Laptop battery using mistakes
2009-11-14
Lives Longer In BIOS? - This is one of the few troubleshooting diagnostic tests you can do at home to find out if your laptop battery life problem is due to a hardware flaw or to the way the laptop is being operated. Enter the BIOS setup immediately after turning on the notebook on with a fully charged battery, usually by hitting the DEL key, the F1 or F2 key immediately after you power on. Some laptops display a text message telling you what key you need to hit to enter the BIOS setup, on others the message is suppressed by a BIOS setting, but you can always go online and Google the right key combination if it’s not in your manual. Once you bring up any BIOS screen, measure the time it takes the laptop battery to run down. If it doesn’t outlast the battery life under regular usage by a good margin, the short battery life is probably due to a faulty battery or a hardware failure that causes the laptop to continually suck power when it shouldn’t.
AC Adapter Noisy? For starters, this is one of those problems that tends to bother more women than men, because men lose their high frequency hearing at a much earlier age than women. Battery chargers typically include a transformer and some power IC’s, at least a bridge rectifier. There’s a lot of potential for humming and whistling with transformers, but they can go on operating that way for years without failing. If the battery charger gets very hot, then it’s time to check the manufacturer specs for temperature and see if it needs replacement, and check the dell Inspiron 6400 battery temperature as well. In all cases, the acoustic behavior of your AC power adapter and charger may naturally vary with the quality of the power from the utility, and the feed voltage if you are traveling. Anytime you can avoid running a computer on poorly regulated or intermittent utility power you should do so, but at least with a laptop you’re better off than with a desktop.
OS Battery Management Active? Older notebooks were equipped with hardware only battery management schemes that controlled both charging and battery operation. All new laptops ship with ACPI (Advanced Configuration Power Interface) which is a marriage between BIOS routines that monitor board level charging and device activity, and the operating system. The operating system power management comes equipped with a number of default profiles that instruct the laptop if and how to nurse the dell Inspiron 640m battery. There’s usually a power user profile that just runs full out with no consideration of battery life, a number of special purpose profiles, such as running a DVD movie for a sole task, and a miserly setting that cuts performance to a minimum and puts devices like the hard drive to sleep when not in frequent use.
You can micro-manage these profiles to suit your needs, and you can always go into the settings and override them or change the profile at any time. The most useful trick to remember for running on dell Inspiron 710m battery is how to brighten or dim the LCD screen using the the function screen. Screen brightness is a serious power drain (you’re essentially powering a small fluorescent lightbulb) and in most indoor usages, strategic choice of where you sit can add time to your battery life. When troubleshooting battery life issues, you may want to run a power management profile that doesn’t come up to your expectations for performance for a few battery cycles just to help diagnose the problem.
DC Voltage Good? Check the voltage at the output of your AC adapter with a DC voltmeter, right on the barrel connector that gets plugged into the laptop. The rule of thumb for acceptable readings on power adapter output is usually a 5% variation either way of the faceplate voltage, and in terms of charging a dell C1295 battery, a high reading is better than a low reading. If you’ve purchased a lightweight battery charger for travel, don’t assume that it’s putting out the correct voltage just because there’s a connector that fit your notebook. Check your owners manual or the label on the original battery charger that came with the notebook.
LED For Charging Blink? While there’s no universal standard, a blinking LED on the battery charge indicator is probably not good news. It often indicates a battery that has been over-discharged, the voltage is so low that it’s confusing the charging circuitry into thinking the battery has a dead cell and would just overheat if a charge is pushed into it. The newer the laptop, the smarter the charging logic, and it won’t want to try putting a charge into a battery that may damage either the battery or the notebook itself. In some cases, you’ll be able to recharge an over depleted dell Latitude D420 battery if you wait until the notebook is shut down, install the battery, and then plug in the the battery charger, but I’d keep a close eye (and occasional finger) on it for overheating. There are also fuel gauges built into some newer batteries that simply disable the battery when it reaches it’s planned cycle life.
Does Battery Get Hot? Recently there have been a spate of high profile stories in the media about laptop batteries catching fire. This wasn’t caused by normal heating due to charging. The problem was in the manufacturing process of the individual cells, where apparently some contamination led to internal short circuits that could cause the battery to overheat even if it wasn’t in use. dell Latitude D430 battery normally heat up a little on charging, and they heat up even more when discharging under heavy demand. Battery packs usually include a temperature cut-off circuit, that will halt battery charging or discharging if it really overheats. In some cases, the battery will not be usable afterwards because the cut-off acts like a circuit breaker that can’t be easily reset.
It certainly doesn’t do your laptop battery any good to get very hot, even if it’s within the toleration of the protective circuitry, so if it’s overheating on discharge, consider running on AC power instead. Just remember you have to shut down before removing the dell Latitude D500 battery unless it’s specified as being hot-swapable:-) You can also try decreasing the performance settings to lower the power drain. If the battery is overheating on charging, you can try charging when the laptop is turned off since the laptop is generating heat as well. Also, pay attention to the ambient air temperature. All notebook computers depend on the ambient air for cooling, so unless you are running the computer on a special cooling pad, think twice about using it on those 110 degree days!
Latch Locks Tight? It’s impossible to see what’s going on with the connector contact inside the battery compartment once the battery is installed, so the only indicator you have to proper installation (aside from normal operation) is the condition of the latch. If the latching mechanism doesn’t show a positive close by clicking back to the relaxed position, try reinstalling the battery. Some laptops have a manual battery lock that is operating separately from the latches, and which will not lock unless the battery is installed properly. If the latches refuse to click closed on their own, remove the battery again, visually inspect for any bulging or distortions in the package, and check the connector for damage.

Notebook Battery daily maintenance FAQ
2009-11-14
Note that these steps correspond with decision points on the flowchart and are reached directly by clicking on the diamond symbols. The text below cannot be read sequentially.
Needs AC Adapter to boot? The first step in troubleshooting your dell Inspiron 6400 battery is determining whether it can hold enough charge to boot the notebook. Will the laptop power up and run on the battery, or does the AC adapter which doubles as the laptop battery charger need to be plugged in? Modern notebooks usually have a whole array of status LEDs that will tell you if the laptop senses good power coming from the battery charger and whether or not the battery is charging. Unfortunately, there’s no universal standard for these LEDs, their colors or their actions. Note also that we’re using the term “boot” rather loosely here. If the laptop powers up on battery, you can hear the fans and the drives, your troubleshooting problem lies elsewhere.
Life Of Battery Too Short? This is the main problem laptop owners complain about, and often for good cause. Older laptops using Ni-Cad and early Ni-MH dell Inspiron 1501 battery often ran for 2.5 to 3.5 hours when brand new, but within a month or so, would barely keep the notebook powered up for an hour. Newer laptops using Ni-MH and Li-ION batteries are much better, often holding onto a three hour life through hundreds of charge and discharge cycles. The first line of defense against complaints about battery life by the manufacturers is always, “Did you charge and operate the battery according to the manual?” Unfortunately, different laptop manufacturers seem to disagree over how to best treat dell Inspiron 1520 battery of the same technology, and I wouldn’t be surprised if the differences extend to different models from the same manufacturer.
If the laptop’s dell Inspiron 1521 battery life has been slowly degrading over time, it’s probably operating more or less in accordance with plan, but if you find the operating life shortened by more than 15% or 20% within the first few months, there’s probably something wrong. Batteries of all technologies can be “trained” to perform poorly through non-ideal usage patterns, but the Li-ION battery technology is pretty resistant, and as long as you run them all the way down once a month or so, you can probably prevent any serious charging memory issues.
Is Battery New? Purchasers of brand-new laptops are often surprised to find the battery is dead, or runs down very quickly. Even if the dell Inspiron 6000 battery was fully charged when the laptop was boxed for shipment, that box may have been sitting in a warehouse for six months or a year before you purchased it in a store, more than enough time for a notebook battery to self discharge to an appreciable degree, even if it’s not being drawn upon. If the battery isn’t new, and you just received the laptop as a hand-me-down or purchased it second hand, there’s no reason to expect that a short dell Inspiron 630m battery life is due to anything other than an aged battery. You can try to recondition the battery (see the laptop manufacturer website for for software that may be available), but odds are the battery simply can’t hold a charge the way it did when it was new.
User Condition Dell Inspiron 640m battery? Some manufacturers may condition the battery before installation in the laptop, others expect you to read the owners manual instructions and do it yourself in the first few days you own the laptop. The most general procedure is to charge the battery fully before use (leaving it on the AC battery charger overnight is best), and then to run exclusively on battery until the battery is discharged. Some brands suggest you run until the operating system warns of low battery life remaining, which could be anywhere from 10% to 3% remaining on standard settings. Others recommend that you run the laptop until it shuts itself down. This doesn’t mean that you have to sit there working for three or four hours, you can run the Dell Latitude D620 battery down over multiple sessions over multiple days. The important thing is not to plug the AC power adapter back in and start recharging the battery until it is completely run down. The condition process generally requires you to go through this cycle three times in a row.
Runs Always With dell C1295 battery? If the owners manual for your notebook suggests removing the battery when plugged in for prolonged periods, doing so may greatly prolong the battery life in terms of both charge cycles and years. Personally, I tend to be lazy and just leave the battery in all the time, despite the fact I almost always work plugged in. The battery life on the first couple Toshiba’s I owned dropped down to a half hour or so of running time within a few months my buying them, so it may have been my fault. Li-ION dell GD761 battery are much more friendly to poor power management habits, but you should run them down to empty once a month to keep them from developing a memory.
Battery conditioning means training the individual dell TD347 battery cells into a pattern of giving as much power as they can and accepting the largest charge that they can. It would take an advanced chemistry text and a person much smarter than I to describe the underlying reasons for battery memory, and the techniques for best charging and storing batteries sometimes contradict one another. Once a laptop battery pack is conditioned, you may still need to run it all the way down once a month for best performance, especially if you normally work with the laptop plugged in. It’s important to read the owners manual section on battery life, because different models ship with different battery technologies, and the best practices to extend the battery life may not be the same.

2012 global solar cell production capacity of 3.2 times for 2008, a substantial increase in Taiwan
2009-11-10
French research company Yole Developpement released in July 2009 predicted that by 2012 the global solar HP laptop battery production capacity will reach by electricity converted 42.78GW. Is expected to win gold medals in 2006 China will by 2012 have maintained the largest producer status. However, its share decreased year after year, 2012 will be reduced to 23.7%.
And in April 2009 compared to the predicted values, Yole global solar cell production capacity increase of 2.37GW. The steepest increase in Taiwan, for 1.03GW. Than forecast in April 2009 the value increased by 29.3%. In the semiconductor and LCD panel businesses against the backdrop of an increasingly sophisticated Taiwanese companies started to focus on the production of solar cells, as the next areas of development.
A result of Spain a "slam the brakes", the first half of 2009 substantially reduced the global demand for solar hp 346970-001 battery ,hp 367759-001 battery, but then began to gradually restored. Especially in Japan, because the Government to restore subsidies on the installation of solar cells, solar cells need to expand rapidly. In addition, as the global demand for solar cells the steady growth in prices began to decline in solar cells also play a catalytic role. -
A car can be completed within a few minutes of fuel to add, but only water vapor emissions. This may sound a bit like science fiction, but it does already exists: the Hollywood star Jamie Lee Curtis and Honda Motor Co. CEO Takeo Fukui has such a horse - hydrogen fuel HP laptop battery cars. This "environmentally friendly" cars have also been some local people became the final version of the next car.
Although fuel cell vehicles to the high production costs, ordinary people are already legendary, but the October 23 opening of the 2009 Tokyo Motor Show, such a hydrogen fuel cell vehicles are still singing the leading role.
Honda president Takeo Fukui at the auto show on the opening day, said: "We believe fuel cell vehicles will become the ultimate version of the car of the future because it has a number of unusually strong advantages: zero-carbon emission, single travel long distances to add fuel, add fuel hp 338794-001 battery ,hp 361742-001 battery time and short. "Last year, Honda will be 200 FCX Clarity hydrogen-powered car has been rented to customers from Japan and the United States, including some of Hollywood's biggest names.
Of course, some other auto makers will not let Honda dominate and, therefore, being a lot of money to pound hydrogen technology research and development, including the Toyota. As a pioneer in the field of hybrid vehicles, the company has expressed its intention in 2015 to introduce a fuel-cell cars, hybrid technology company in which the advantages of application. Responsible for developing the first generation Toyota Prius hybrid car in Yamada, chief engineer Wu said: "We can not focus solely on a single technology." The company president Akio Toyoda said the company hopes can become short of pure electric vehicles, Ideal for traveling, hybrid has become essential for long-distance travel.
In addition to these two companies, Nissan and Mazda has also developed its own fuel cell vehicles, and has rented their products to the government and corporate clients. In the Tokyo Motor Show, the Suzuki company also displayed the company's newly developed fuel cell vehicles, wheelchairs and scooters.
At present, each hydrogen-powered cars cost as much as several hundred thousand dollars. Therefore, in research and development process, the major car manufacturers are faced with how to reduce production costs. However, this does not scare off investors. Asia Ash, executive director of automotive intelligence agencies Wen Elcoteq, said: "It is envisaged by 2050, the number of fuel cell vehicles will be more than pure electric vehicles. The ultimate goal of vehicle manufacturers may include the use of renewable energy (such as solar energy) electrolytic water to produce hydrogen, so hydrogen powered cars. "
Although the majority of vehicle manufacturers will continue to focus on hybrid cars or pure electric vehicles, fuel cell vehicles, but supporters say that, although the development of hydrogen-powered vehicles than the hybrid and pure electric vehicles hp 371785-001 battery ,hp 372772-001 battery a step late, but it has a More advantages: fuel Adding a short time, a single trip so far.
Another professionals believe that the future of small electric vehicles will be the ideal choice for short-haul travel, while fuel cell technology is more suitable for large vehicles such as trucks, hydrogen fuel cans because the dress would account for a lot of room. In addition to cost, the hydrogen charging stations and the lack of an appropriate size models are also developing fuel cell vehicles on the road obstacles.
This year in September, Toyota, Honda, Hyundai, Ford, General Motors, Daimler, Kia Motors Corporation and other well-known joint statement, called upon the Government in 2015 to build more hydrogen fuel infrastructure. If this goal can be achieved, from 2015 onwards, I believe that worldwide there will be a few 100,000 hydrogen-powered vehicles progressive realization of the commercial production. The U.S. Congress recently passed a resolution, agreed to invest 187 million U.S. dollars for research fuel cell, which will greatly promote the development of fuel cells.
General Motors Asia-Pacific region is responsible for the commercialization of fuel cells, George Hansen, said: "The application of fuel hp 398876-001 battery ,hp 417066-001 battery there is no shortcut to take. We already have the technology, now what the Government is willing to build the appropriate infrastructure, while mass production can reduce costs. " -
Electric vehicle batteries often stolen, this is what our electric vehicle users often encounter problems. So how to solve this problem do? That is multi-function battery lock.
In the just-concluded 15th session of the primary and secondary school teachers and students of Nanjing Science and Technology Invention Contest, on a small Xiaguan District, Nanjing City invention of a small primary school students come to the fore, causing the judges attention. That is a multi-function battery lock, was awarded first prize for the city's small invention.
The inventor of multi-function battery lock is a small city in the fifth grade students in Chen Kun, he invented multi-function dell Inspiron 1100 battery, Dell Inspiron 1300 battery lock is very useful, both to protect the battery, but also into a small bench. According to Chen Kun, said her mother often sent him riding a bike to school, in order to prevent the battery was stolen, the car often with a large chain lock, but the phenomenon of electric vehicle batteries were stolen are still serious, a lot of thieves are fixed to the vehicle owners forget the lock battery or the battery lock very few electric vehicles. How to make the battery lock to become more solid, more convenient to take the battery, these problems became his research goals. He first tries to folding chairs at one end fixed to the electric car, the other end can be freely folded into the seat, fold flat when not in contraction, and the fixed-side electric car lock, the entire battery is folded after seat lock at the bottom, forming a lid, so that the battery is very safe. Locks and seats can also integrated, does not affect the appearance. Chen Kun, said he is also very useful for this invention, there are the parents of a child seat when riding put away, the children sat on it is also very safe, very comfortable, parents also eliminating the seat back and forth with the trouble. Take the battery, as long as the lock open, up folding chairs can be removed off the battery.
According to Chen Kun's father, said Chen Kun had a habit of blind Daogu run into problems, a habit, and engage in radio uncle explore the invention of a three grade will be blowing bottles, the school held in October this year, Science Week, so Students come up with "creative ideas gold," Chen Kun thought the electric car battery lock. Zhang Xiang, under the guidance of their teachers, he put the idea into reality, never thought that also was the first prize. Chen Dad believes that these have benefited Dell Inspiron 1501 battery, Dell Inspiron 1520 battery from science and technology teachers pointing in peacetime to enable students to observe life, from life to discovering problems, find solutions to problems before students have invented power. -
October 20, 2009, the EC issued notification, the European Commission proposed to amend the development on the portable rechargeable battery (rechargeable) and automotive batteries and battery capacity labeling rules.

On the Sony Ni-Cd Battery
2009-10-26
Nickel-cadmium battery is present in the negative cadmium (Cd) and sodium hydroxide (NaOH) in the hydroxide ion (OH-) generating hydroxide compounds, cadmium, and that this compound attached to the anode, and can also release e. E-flow along the wires to the cathode, with cathode nickel dioxide and sodium hydroxide solution in the water reaction, and then produce nickel Sony laptop battery hydroxide and the hydroxide ion, nickel hydroxide will be adsorbed on the anode, so that hydroxyl ions also Huitang to the sodium hydroxide solution, the resulting concentration of sodium hydroxide solution does not change over time wastage.
Nickel-cadmium batteries were the first used in mobile phones, laptop computers and other equipment, the battery type sony PCGA-BP2E battery,sony PCGA-BP2NX battery, which has excellent high-current discharge characteristics, resistance to over charge and discharge capability and easy maintenance. Nickel-cadmium batteries of the most fatal flaw is that in the charge-discharge process if not handled properly, there will be serious "memory effect", makes the service life shortened. The so-called "memory effect" is the battery in the charge before the battery power has not been completely exhausted, the battery capacity over time will cause the reduction of the battery charge and discharge process (discharging more obvious), would be very on-board battery is some of small bubbles, these bubbles accumulate and reduce the size of the battery plates also indirectly affect the battery capacity. Of course, we can control the charge and discharge reasonable way to reduce the "memory effect."
In addition, cadmium is toxic and, therefore, nickel-cadmium battery is not conducive to the ecological environment protection. Since traditional sintering process is extremely negative, cadmium and coarse grains, if the nickel-cadmium battery is fully discharged before they are re-charging, easy to gather Manifold Ershi grain cadmium battery discharge formed when the secondary discharge plateau. Discharge the battery will be stored in this platform and in the next cycle will end as a discharge, although the capacity of the battery itself, can make the battery discharge to a lower platform. In the subsequent discharge process in the battery will only remember the low volume. Similarly, every time you use, any one not fully discharge all will deepen this effect, so that the battery capacity becomes lower.
Nickel-cadmium battery cathode active material from the board of nickel oxide powder and graphite powder composition, graphite not participate in chemical reactions, whose main role is to enhance the conductivity. Negative electrode active material from the board of cadmium oxide powder and iron oxide powder composition, the role of iron oxide powder is to cadmium oxide powder have a higher proliferation, prevent clotting, and increase the plate capacity. Active substances were wrapped in perforated steel, the compression molding was turned into positive and negative battery plate. Between plates of hard rubber insulation with alkali-stick or a hole PVC corrugated plates separated. Electrolyte is usually potassium hydroxide solution. Compared with other batteries, NiCd batteries self-discharge rate (ie, the battery loses charge when not in use rate) moderate. NiCd batteries in the use of process, if not completely discharge on another charge, discharge next time, you can not release all the power. For example, the release of 80% of the electricity and then fully charged, the battery will only emit 80% of the electricity. This is the so-called memory effect.
Finally talk about the packaging under the nickel-cadmium batteries sony PCGA-BP2NY battery,sony PCGA-BP2T battery,sony PCGA-BP2V battery, which contains retail use of the positive convex head plate, and assembly used in both positive Flat packaging, they in terms of volume, and there is no difference. In the charge back on the road is also similar with the nickel-metal hydride batteries. But one thing is different is that nickel-cadmium battery memory effect than Ni-MH battery should be obvious. Therefore, to ensure that life will not be affected, then they would pay attention to daily maintenance in the use of electricity before carrying it out completely without charge. -
Today, modern electronic products have more and more features, and more complex, more and more compact shape, weight, become more portable, under such compaq laptop battery circumstances, provided there is a higher power battery requirements. The emergence of nickel-metal hydride batteries allow more people to use. Nickel-metal hydride batteries as the positive electrode nickel hydroxide in order to be free to absorb ﹑ release of hydrogen as a hydrogen storage metal alloy anode. Compared with the nickel-cadmium batteries, nickel-metal hydride batteries, more than twice the energy density and energy, there is a similar voltage. In the design of portable products and wireless communications equipment, the engineers have a variety of battery solutions to choose from, including the nickel-metal hydride battery (NiMH), lithium-ion batteries, lithium polymer batteries, and advanced lithium batteries (ALB) and so on. Among them, Li-ion battery with its high energy density and continue to lower the price to be more and more widely used; Ni-MH battery than the nickel-cadmium battery energy density, lighter and more environmentally friendly memory effect, so in many portable applications continues to occupy a place. Ni-MH battery with standard size, in most applications can be a direct replacement for alkaline batteries, and has superior security features, anti-overcharge ability is good, ultra-high discharge rate, discharge platform, ultra-low resistance, long service life long, STAR high-capacity fine compaq EVO N400c battery features.
In this paper, a standard for AA and AAA nickel-metal hydride battery charge controller for nickel-metal hydride battery charge management techniques are discussed. In addition to the completion of the charge controller controlling the outer Ni-MH battery charging. You can also identify the cell type, to avoid alkaline batteries.
A Ni-MH battery charging algorithm
With the extensive use of nickel-metal hydride batteries, the charger also introduced a number of techniques. Generally require use of constant current source for nickel-metal hydride batteries, when the meet is full of state, the battery exothermic chemical reaction will occur and lead to the battery temperature rises, the battery terminal voltage reduction. Can detect the battery temperature increase rate or a negative voltage change rate, to terminate charging. Fast charge will be 0.lC after the end of the charging rate of about 30 minutes of float, thereby completely adequate battery. To compensate for the self-discharge Ni-MH bcompaq EVO N410c battery,compaq EVO N400 battery effect, after the completion of floating out before the battery charger will always C/20 or C/30 trickle charge the battery remained at full state.
Two super-new Ni-MH battery charger
They can constitute a stand-alone charger, or embedded systems to use, and can be flexibly configured to the battery or batteries in parallel concatenation structure. Both devices use the same temperature, voltage and charging parameters such as to carry out fast-charge control, and to provide float and trickle-charge and other basic functions. The most important thing is that they can also automatically test the battery type, to avoid alkaline primary batteries. Example below to DS2712 their charge control and battery detection explanation. The charge controller can also automatically detect the battery type, and to avoid other types of batteries. The tests are mainly based on nickel-metal hydride batteries and alkaline batteries to achieve the impedance difference. Although different manufacturers offer battery impedance will be different, the same battery charge state in a variety of resistance will change, but, in general, alkaline battery internal resistance than nickel-metal hydride batteries is much higher. Therefore, by detecting the battery internal resistance DS2712 determine whether the compaq EVO N410 battery,compaq Evo N600C battery charge. Good performance with safety features, high standards of production and quality control of model aircraft-specific batteries to create superior safety performance, in the subject than the harsh conditions of use, but will not have security issues. At the same time long, long life, according to customer requirements, Shida power battery 0.5C cycle life can reach 500 or more times, 0.5C-current charge-discharge cycle life of up to 300 times. -
Sodium sulfur batteries, a battery-new member of the family, as a leader in high-capacity battery, is optimistic about the potential of the most competent urban power savings, "super-bank." Yesterday, reporter learned from the DELL laptop battery CAS Shanghai Institute of Ceramics, from the Institute and the Shanghai Electric Power Company jointly developed "high-capacity storage of sodium sulfur batteries City Network," made important progress in the subject this year, will develop 100 kilowatts by the end of the sodium level of sulfur battery energy storage system, and access to the Expo next year will be displayed.
City Power is now faced with many challenges, including: poor disparity between peak and valley power consumption, safe operation of increased risk, power quality requirements increase, the rapid development of new energy, but the performance of unstable grid. If it is not an effective solution to the above-mentioned "instability factor", it is prone to blackouts. The first blackout of a city's "mass destruction", even if only a few seconds, but also no less than a major earthquake. Want to improve grid stability, essential for large-scale energy storage: it is like ibm ThinkPad R50 battery,ibm ThinkPad R50e battery power bank, make the same power as the money they deposit will be taken.
Sodium sulfur batteries, is a kind of metallic sodium anode, sulfur as a cathode, ceramic tube membrane electrolyte secondary battery. At a certain temperature, the sodium ions through the electrolyte membrane and the reversible reaction between the sulfur and form of energy release and storage.
In terms of urban power grid, sodium sulfur batteries rated as an effective "assurance." Sodium sulfur storage battery with large capacity, small size, energy storage and conversion efficiency, long life, without geographical restrictions, etc., are very suitable for electrical energy storage. After comprehensive analysis, sodium sulfur storage battery is the most economical and practical storage methods, is the large-capacity storage battery in the crowd. Pumped-storage, in need of special sites; metal - air battery, charging problems; lithium batteries, the cost too high; lead-acid batteries, life is too short, anyone not as reliable, sodium sulfur batteries.
Therefore, the sodium sulfur battery research and development at the international level in the ascendant. In August 2006, the Shanghai Silicate Research Institute and Shanghai Municipal Electric Power Company to carry out a large-capacity single sodium sulfur battery research and development co-operation. 5 months later, 650Ah battery of single trial success, after Japan, China became the world's second largest-capacity to master the core technology of sodium sulfur battery single country in August 2007, the two sides build a "Shanghai Development of sodium sulfur battery base "and soon captured the preparation of sodium sulfur batteries key technologies, has successfully developed more than 170 sets of production with its own intellectual property and performance evaluation of equipment, and run through the annual output of 2 megawatts of sodium sulfur storage battery pilot line, to achieve 10 kW energy storage system successfully demonstrated.
It is predicted that by 2020 China plans to build a comprehensive unified "strong smart grid" and its technology and equipment to fully reach the ibm ThinkPad R51 battery,ibm ThinkPad R52 battery,ibm ThinkPad T40 battery international advanced level, when the national grid of clean energy installed capacity ratio to 35%. In Shanghai, for example, by 2010, power grids, the largest difference peak and valley will reach 13,000 megawatts in photovoltaic cell industry will reach 1,500 megawatts, according to 20% of the total storage capacity of configuration, large-scale energy storage devices, the market demand of at least 560 MW. -
Auto energy-saving emission reduction has become the driving force behind the development of automotive electronics, with the increasing oil supply shortage and growing environmental pollution, electric vehicles such as electricity-powered vehicles, with its energy-saving and environmental protection advantages of becoming a concern to the industry focus DELL laptop battery. However, even if the electric car has many advantages, but it is a time can not replace the traditional gas powered model, so the new hybrid vehicle is clean electric vehicle with industrialization and marketization of the most promising models. However, batteries, cost, reliability, longevity, more complex environment, the requirements of high-voltage power devices for automotive manufacturers and many other issues facing the many challenges.
Infineon Technologies (China) Limited's automotive electronics business, senior marketing engineer Cao Yu pointed out: At present, the main challenges of hybrid cars from two aspects: one is the traditional power systems and electric systems of coordination; the other is the need for cost-controlled conditions, to meet the automotive electronics in complex application environments reliability requirements .
Cao Yu: Hybrid cars as a major challenge is the traditional power systems and electrical systems for coordination dell Latitude D430 battery,dell Latitude D500 battery.
Fairchild, senior manager of global automotive market, Hans-PeterHoenes believes that hybrid vehicles the main design challenges are based on a very low cost to create a very complex and yet highly reliable systems.
"Electric cars can be divided into three categories: hybrid, fuel cell and electric vehicles. Electric car there is a universal problem - battery, batteries due to the existing problems, the future can be the possibility of mass production the largest is the hybrid. than a hybrid engine with conventional technology, an increase in three parts, one vehicle control, 2 battery management, and third is motor control. "Freescale's automotive electronics engineering manager for China, said Kang Xiao Dun .
Kang Xiao Dun: The battery technology is the key to hybrid cars, batteries account for the cost of the vehicle 1 / 3 of the above.
Hybrid electric vehicle is further divided into light (micro) mixed with full hybrid vehicles, the challenges they face are different.
Light mixed with the different challenges facing the entire mixed
Cao Yu analyzed, micro-mixing system and the entire hybrid system in the system are structurally very different, it is more than the total electrical power system, the percentage of the value of difference is important that the quantitative changes in the structure caused by vehicles. Micro-hybrid system in general to achieve start-stop function, the whole hybrid system requires no engine power vehicles in the case still has some endurance dell Latitude D505 battery,dell Latitude D510 battery. Because the system greatly increased the coupling degree, full-hybrid system structure is more complex and more challenges in the design.
Hans-PeterHoenes were analyzed for the mild hybrid vehicles, the chassis (the basic design) is still the traditional automotive design, usually in a normal car on the integration of hybrid characteristics. As the chassis (the basic design) design has been set, the additional needs of all systems must be able to meet the demand. However, this is not always the best technical solution, so far the biggest challenge in this regard is the integration of mechanical and electrical integration. In other words, the minimum space requirements need to design. As for the full use of hybrid cars, the whole design needs to change, not only the powertrain, chassis and even had to move forward and is optimized for mixed. A good design should be designed around the automobile powertrain, while the traditional program is designed to cars, but the engine placed in the "somewhere." This is a complete change in the concept of design thinking, because drive system has been decided, or at least greatly affect the shape and appearance of the vehicle.
"Design work is facing the biggest challenge is the lack of high-power electric transmission under high pressure (high pressure-driven high-power motors) has extensive experience in automotive engineers. As a result of conditions and the traditional cars are different, so even in the field of industrial drives and experienced Senior consultant, can offer the help is very limited. "Hoenes said. Fairchild not only has a discrete power technology, as well as gate driver IC such as IC. This not only applies to low-voltage, but also covers the full voltage range of up to 1200V. This module integration capability allows customers to receive a fully tested to optimize power level, can solve many problems related to the interaction between the parasitic and device design issues.
Motor Control Challenges
In motor control, Cao Yu pointed out that the main difficulty is the need to achieve auto-level reliability requirements, and needs to take into account the cost of realization of the right. Also need to consider the high-power drive system caused by electromagnetic interference and noise effects. If you are using industrial-grade device although the initial period of no major problems, but as time goes on, accompanied by a device destined to produce failure, vendor will give the brand image and reputation has brought incalculable loss, "so we recommend the use of automotive-grade devices, can effectively guarantee the vehicle's life cycle system, reliable operation. "he said. "As the world's leading supplier of power devices, Infineon has a deep system of experience and many experts team, which can better understand the specific needs of customers, even helping customers find those hidden in the system application requirements under the details."
Infineon offers the industry's leading provider of high power density automotive-grade module HP1 (hybridpack1) & HP2 (hybridpack2), with ultra-small size, the most relevant automotive systems of space limitations. HP1 weight 485g (72x140x17mm) 3 half-bridge in-one design, 650V400A maximum drive capability for less than 20-30KW motors. HP2 (106.5x48.5x20.5mm) weight of 1250g, is more directly based on a special water-cooled thermal design in order to meet the 80-100KW Module 650V800A motor applications.
Microchip Automotive Products Group Automotive Marketing Manager, Chan Chung-yan, the view that: "In the hybrid vehicle, the motor control for steering control, and battery cooling and other key subsystems is critical. Brushless DC (BLDC) motors due to small size, controllability and high efficiency The widely used. brushless DC motors are increasingly being used to eliminate the belts and hydraulic systems, to provide additional functionality and improved mileage. magnet costs continued to decline and control of brushless DC motor of the electronic devices needed to continue to reduce the dell Latitude D520 battery,dell Latitude D600 battery, leading to more and more used cars, power level is also rising. "
Chan Chung-yan, went on to explain, DC brushless motors are usually controlled with one or more of the rotor position sensor used in conjunction with, because their electrical excitation must be synchronized with the rotor position. For the cost, reliability and mechanical packaging reasons, especially if the motor need to being immersed in a fluid, preferably in the case of sensorless brushless DC motor running - that is, without sensor operation. Sensorless motor lower cost, because it does not require sensors, but the driver is more complex. Sensorless Motor in Hybrid Electric Vehicle Battery cooling system has excellent performance, this time do not need to start and stop the motor. "Automotive system designers embedded in the face of changing environment, the need to develop a cost-effective and environmentally friendly solution. Low-power micro-controller is an important device to meet the demanding requirements, which can increase the cost of lower reliability of the system in a small package to adapt to a smaller board space, and no external components. In addition, to have the socket, software and peripheral compatibility with micro-controller architecture provides designers with excellent flexibility, enabling them to shorten the development time and reduce costs. Microchip Technology offers a variety of micro-controllers and DSC, for facing the challenges of hybrid demand for automotive electronics designers is the best solution. "
In the powertrain systems, Cao Yu think the biggest challenge is how to coordinate the motor system and the traditional power system operation, give the user a better driving experience. Improve the efficiency of the whole system mainly from the following aspects: improving motor system efficiency, braking energy feedback rate, reducing the efficiency of the engine at low speed range of operation and so on.
For motor control, Kang Xiaodui Freescale, "said Freescale's gasoline engine management electronics a global leader. We offer advanced embedded controllers, sensor technology, power management components and power brakes drive, so that the new vehicle more economical, and protect the environment. We're still the engine control technology introduced into the electric vehicle control and management, and based on PowerArchitecture Freescale processors MPC55/56xx series offers many of the most advanced engine control, vehicle management, electrical drive, battery management solutions. "
Battery management is facing the biggest challenge
In the (full) hybrid vehicles, the battery is the most expensive, but also the most delicate parts. Although the lithium battery with high power density advantages, but in the development of suitable batteries for hybrid cars, there is still a lot to be done. In this case, the next few years, nickel-metal hydride (NiMH) batteries will still be more and more widely used.
Hans-PeterHoenes pointed out that to achieve the fast charge without damage (damage) batteries, designers need a very precise charge (charge) control technology. Although the micro-controller integrated intelligent programming algorithm is basically a software solution, but Fairchild continued to focus on the hardware. In order to avoid interference with power lines during charging, a good power factor correction solution is necessary, to some extent even a legal norm requirement. The control IC Fairchild has an extensive product portfolio, combined with built-in with a soft-recovery rectifiers (performance of the rectifier diode) and low saturation voltage drop across the IGBT, can provide a complete solution.
In the battery management, Cao Yu Li-ion battery that Infineon has a dynamic balance of Application patents, can reduce the differences between each other, effectively improve battery efficiency and longevity. This patented feature is the battery charged and discharged, or any idle time to implement power balance, very suitable for automotive power applications in such diverse environments and rapid mode switching needs.
"In view of current technology, battery technology is the hybrid cars and electric cars key. Even a relatively high market appeal hybrid cars, batteries account for the cost of the vehicle's 1 / 3 or more. But also the weight of , reliability, longevity and many other issues to be resolved. lithium iron phosphate battery technology should be a better solution. However, as regards the above problems still need further improvement. Fuel cells are another technology, its technical maturity, fuels (mostly liquid hydrogen) storage and control issues, we can say can not immediately become a mature, mass-produced products. while pure electric cars, hybrid terms, the battery cost, weight, reliability, life , including the charging issue will be the government, automobile companies are facing a major problem. "Kang Xiao Dun said," So, the current hybrid vehicles in Europe and the United States and Japan, and has become industrialized, and domestic dell Latitude D610 battery,dell Latitude D620 battery,dell Latitude D800 battery still in its infancy, there is no formation of industrialization. As the world's leading automotive semiconductor manufacturers, Freescale is committed to the Chinese domestic automotive electronics contribute to the development. Our key customer support (such as BYD, etc.), including technical exchanges, product pricing and so on. " -
The new University of Florida (UF) has just revealed one of its new laptop battery study: solar cells can achieve a more cost-effective, more efficient light capture and collection of new programs.
Energy path is achieved through molecular movement molecular accumulation and transmission for this new study press release, "Valeria Kleiman, and three collaborators to obtain real-time monitoring of the path.", They use "for the stages of laser pulse, "or" special dell Inspiron 9200 battery,dell Inspiron 9300 battery spectrum at different speeds, "access to a different source of energy. As Kleiman found that they can affect the energy in the "coding pulses in the excited state of different information."
Solar or solar photovoltaic researchers now have the ability to identify the optimal molecular structure for use in photovoltaic devices (storage and conversion of energy), to create a cheaper, more efficient solar cells.
Valeria Kleiman said the findings "not only enable us to understand how the molecular reactions between, we can change the reaction pathway, so we can test different energy transfer channels to identify the most efficient path."
Kleiman explained: "Suppose you want to go from here in Miami, but the road ahead blocked, we can tell you, 'Do not select this one and take another one bar'."
It appears that this exciting new dell Inspiron 9400 battery,dell Inspiron B120 battery discovery is the solar energy researchers and the general public has been hoping and waiting. -

Adding to the positive battery performance
2009-10-12
The cobalt added to the Ni (OH) 2 electrode is mainly based on the formation of high conductivity of CoOOH, at the activation stage of the process of charging, is oxidized into CoOOH, thereby enhancing the conductivity of a pole piece HP laptop battery, because this reaction is not reversible, so add the Co there is no contribution to the capacity of the electrode.
In the Ni (OH) 2 electrodes of cobalt can be added to increase its proton conductivity and electronic conductivity, thereby enhancing the utilization of positive active material to improve the charge-discharge performance and increase oxygen over-potential, thereby reducing the charge voltage to improve the charging efficiency . However, adding an excessive amount of cobalt not only cause the battery to increased costs, will reduce the discharge voltage.
Studies have shown that, in the nickel hydroxide electrode added 10% Co (OH) 2 can reduce the spread of active substances increase the electrode resistance and depth of discharge (DOD). Partial oxidation of the CoO surface showed the best hp 417066-001 battery ,hp 346970-001 battery activity, the surface without pre-oxidation of the CoO (ie S-CoO) is also very active, but because of its instability in air, with oxygen exposure Ershi deep oxidation activity decreased.
With the deepening of the surface oxidation degree, CoO activity gradually decreased, but in 20% before a decrease is not obvious, oxidation degree of more than 20%, then the activity dropped sharply. This is due to the surface of high-priced states Co3O4 too much impact on changing the time of CoO in the formation.
Content on the positive impact of utilization: Add a small amount of (2Wt%) without pre-oxidation of the surface of CoO can obtain a higher utilization of positive active material, in the 5Wt%-10Wt% get the best results within the framework of hp 367759-001 battery ,hp F2024A battery. Prior to joining 10Wt% higher than after the battery capacity actually decreased, which is due to the amount added is too high, reducing the amount of active material filling, then the battery capacity can not be improved, but also increase the positive production costs.
Cobalt addition on the battery large current discharge performance impact: by adding cobalt to improve the large current discharge performance of the battery has a good effect, adding the amount of the more high-current discharge performance of the better, but adding excessive costs rise more, and the battery capacity decline in the proportion of suitable 5Wt%-10Wt%.
Cobalt in electrical activation period (the first charge), as Co (OH) 2 oxidation potential than the Ni (OH) 2 oxidation potential low, which resulted in Ni (OH) 2 into NiOOH before they form a stable CoOOH not only greatly reduces the contact resistance between particles, but also greatly increased the particles and the matrix conductivity. If the discharge voltage is not obvious after less than 1.0V, then the CoOOH no longer involved in the follow-up response to the battery, so the negative would be the corresponding total charge on the provision of this pre-charge. If the subsequent discharge to the available capacity has been exhausted positive, but because of pre-charge of the reasons, there are still negative discharge reserve, it can be avoided to some extent the negative battery terminal a large number of hydrogen evolution and to ensure the efficiency of hydrogen compound.
Cobalt additive with some of these advantages, but it also had a negative result in micro-shorts and beyond, such as increased self-discharge, the reason some people think that:
Positive in the cobalt compound dissolved in concentrated alkali to form cobalt complexes, which migrated to the diaphragm, it will divide molecule oxidation, itself is reduced to cobalt and deposited on the diaphragm, while cobalt complex was also through the membrane to reach the negative film, When the negative charge, and when reduced to cobalt deposited. Deposited on the membrane after a certain amount of cobalt can accumulate to form a very thin membrane, "Co-Bridge", the electron conductivity, initially caused by micro-short-circuit, later developed into a full short-circuit, so that the battery failure, deposited on the cathode hp F2024B battery ,hp F4486B battery on the Cobalt if not generate "cobalt bridge" may also be raised due to the negative surface of cutting-edge of cobalt in the charge and discharge point discharge occurs when the result of micro-short-circuit. Negative in the Mn dissolution also can lead to micro-short-circuit, but also will accelerate the dissolution of manganese dissolution and alloys of cobalt oxide. This micro-short-circuit the battery self-discharge is also an important reason. Filling the battery after the seal and seal immediately after the fast part of the electrical charge can reduce the likelihood of micro-short circuit, that is first converted to the cobalt CoOOH. -
Electrolyte as an important component of the battery, its composition, concentration, quantity of how much and the type and amount of impurities will be the performance of the HP laptop battery a crucial impact. It directly affects the capacity of the battery capacity, internal resistance, cycle life, internal pressure properties.
By comparison found that the electrolyte generally use about 6mol / l of KOH solution (NaOH also has a certain place of KOH) and of course by adding a small amount of electrolyte also has other components, such as LiOH, etc., but for some impurities, such as carbonate, chloride, sulfide Deng Jun demanding.
The battery positive and negative film only in the electrolyte in the electrochemical reaction can occur. For a sealed hp 338794-001 battery ,hp 361742-001 battery is finished, where space is for certain. If the electrolyte too much room space would result in smaller letters the tone Ershi battery charging and discharging process of internal pressure rise; the other hand, the electrolyte membrane to plug holes caused by too much, preventing the conduction of oxygen, hydrogen quickly compound the negative it will also cause increased pressure within the battery and may cause oxidation of a pole piece pole piece passivation capacity decline in the rise in pressure may cause battery leakage, climbing base, making the battery failure. However, if the electrolyte is too small would make great films can not be fully impregnated into the electrolyte, which electrochemical reaction or a pole piece is not entirely certain parts of the electrochemical reaction can not occur, making the battery capacity of less than design requirements, resistance change large, shorter cycle life.
KOH electrolyte is usually not the main use of NaOH, the main reason lies in KOH than NaOH higher than conductance, and in KOH solution by adding a small amount of LiOH in order to enhance the battery discharge capacity. It is now necessary to look into the impurities in the electrolyte and LiOH on the battery performance impact:
In the long-term charge-discharge process, Ni (OH) 2 particles will gradually thicken, so that charging difficult. Reason is the high temperature, electrolyte concentration as well as at a metal impurities. When adding LiOH when it adsorbed on the active material particles around to prevent the particles increased, so as to maintain a high degree of dispersion. However, by adding LiOH not too much, otherwise it will affect the electrical activation process. Is generally believed that iron reduces the oxygen over-voltage, so that the battery charging efficiency decline, carbonate film on the electrode surface is generated, so that the battery internal resistance increases; dendritic resultant sulfide will form, causing the battery short-circuit; silicate can be the electrode capacity loss; chloride electrode is caused by corrosion; while organic compounds but it will increase the self-discharge effects and the outbreak of the Deputy reactions. Therefore, the electrolyte must be controlled impurity content.
Finally, it should be noted that the concentration of electrolyte in order to reduce the concentration resistance.
Why is the battery in the storage and use of the process (cycle) appears to reduce the internal resistance increases and the discharge capacity and charge efficiency go down?
I think that are many reasons for this:
First, the additive Co in the storage and use of the process will spread to the pole piece or move deeper, resulting in a pole piece surface of the Co content decreased, making the pole piece surface of the contact hp 371785-001 battery ,hp 372772-001 battery resistance increases (expressed as impedance rise), thereby reduce the charging efficiency and oxygen evolution over-potential, eventually leading to decline in discharge capacity.
Secondly, in the recycling process, the pole piece is the electrolyte corrosion, resulting in a pole piece powder loose, fall off or bad contacts (particles and particles, between particles and the substrate) led to increased resistance, as well as the excessive charge / discharge cause pole piece damaged.
Third, a pole piece may be due to expansion of the diaphragm in the electrolyte squeezed and sucked out, due to the electrochemical reaction is always carried out from the surface and then again deep development, and therefore result in incomplete electrochemical reaction, resulting in decreased discharge capacity; and because of the lack of electrolyte, resulting in increased resistance (concentration and ion conduction resistance of resistor / relocation of resistance rise), charging potential increases discharge voltage drop.
Fourth, it may be due to the electrolyte in the water or stored in a loop, after a period of time, in some form is not yet clear, such as crystal water, was bound van der Waals forces, was bound by hydrogen bonding and other forces, but not involved in electrochemical reaction (ie increase the concentration of the electrolyte), resulting in difficulties in the electrochemical process of ion conduction, resistance increases, charge potential increases discharge potential drop, eventually leading to decline in discharge capacity.
Finally, it may be due to the battery in the loop or storage process, the electrolyte is re-distribution, proliferation and infiltration into the pole piece and going deep, resulting in a decline in the electrolyte the electrode surface, while the electrochemical reaction is always carried out from the surface then again deep development, and therefore result in incomplete electrochemical reaction to a series of problems arise.
Of course, the battery in the course of the excessive charge / discharge, causing the battery pressure relief, hydrogen / oxygen from escaping and bring out the electrolyte, making the electrolyte dries up, is also important reasons.
Anatomy of open storage and used batteries, you will find inside the battery plate and separator paper drying (visual), is perhaps one of the reasons mentioned hp 398876-001 battery ,hp 417066-001 battery above, or the result of several factors. -
Sanyo Electric Co., Ltd. 26 to determine the latest plan shows that the company will, during the fiscal year the car with the Ni-MH DELL laptop battery capacity by 2.5 times. Investment Advisor in the new energy automotive industry researcher Li Sheng-mao said Sanyo Electric to increase production capacity, mainly due to hot-selling hybrid vehicle on the nickel-metal hydride batteries due to increasing demand.
It is reported that Sanyo Electric is currently the U.S. Ford Motor Company Honda and supply batteries. Honda's new hybrid insigh Launched in February of this year, orders have exceeded expectations, sales are very hot, also boarded the same month in April new car sales charts. Honda expects its hybrid sales this fiscal year will reach 6 million units, equivalent to about 5 times the previous year dell Inspiron 710m battery,dell Inspiron 8500 battery.

The battery itself may be due to defects within the sluggish battery charge discharge which caused explosions; 2, the battery's internal batteries overcharge. As the lithium batteries in special circumstances, such as bad contact, temperature, humidity properly, it may lead to transient overcurrent conditions which led to the battery fire or explosion; In addition, the short-circuit the battery explosion is caused by one of the reasons.
People buy cell phone batteries are most in need of attention: first, mobile phone battery nominal voltage and voltage to match mobile phones, if not match, do not use, otherwise it will cause damage to components, etc.; Second, strict test battery sampling tests and inspection documents show that the regular battery packing box generally have the statement. In identifying aspects of each brand of batteries have different identification methods, through the following points on the purchase price is still relatively cheap China-made batteries are very helpful:
An appearance on the identification
High imitation counterfeit batteries and the battery is the most common problems exist: the core components of the battery cell chips of poor quality, mainly the volume charge and discharge time is too short, the anti-sabotage poor performance, easy to leakage, the actual nominal power also that are not matching.
The original mobile phone batteries generally have the following exterior features: use of a secondary battery label printing technology, in certain light, and from the slope of view, part of the color bar is more dark. Mo Shangqu hand, feeling slightly awkward than the other parts, many brands of original equipment batteries have such features. Genuine white label batteries at designated light metal objects, similar to a pencil scratches. Special material shell is relatively strong, difficult to damage, usually under the battery cover seal better, neat appearance, there is no extra flaws feel quite comfortable hp Business Notebook 6510b battery , hp Business Notebook 6515b battery.
Cell phone battery electrode and the width of film is akin to the appropriate location in the bottom of the battery electrode polarity marked "+","-" mark battery electrodes separation between the materials and shell materials, the same as the battery into phone feel comfortable. Battery lock push part of the card spaces appropriate, firmly. The battery label writing is also relatively clear, there are corresponding with the battery type of battery parts number. Battery manufacturers LOGO should outline a clear, anti-counterfeiting marks the brightness is better, there are three-dimensional look.
Second, the weight on the identification of
Under normal circumstances, the weight of lithium-ion battery is not thick, each cell of about 100 grams; taking into account the obvious features, we can use the method of measuring the weight of mobile phone batteries to identify whether the shoddy battery battery. After all, other types of batteries, lithium batteries with relatively large difference in terms of weight, overweight, too many or too light if the battery if the battery can be roughly inferred are fake and shoddy products.
3, color on the identification of
In the purchase of mobile phone battery, the appearance of the battery when you buy a friend a number of places where more attention, but now the battery fabrication process is also very amazing a lot of cases, and original equipment batteries do not see the difference. However, I still sum up the experience in this consumer: buy batteries, cell phone battery exterior color, usually the appearance of the color line and cell phone. Under normal circumstances, the appearance of genuine mobile phone batteries appearance of colors and color is basically the same. Therefore, we have just selected to the battery, be sure to try on the phone, if the gap is too large, that the battery may be inferior goods.
4, texture on the identification of
A certain type of cell phone batteries, texture can be hard or not in accordance with the method to identify the authenticity of the battery leave. Can force users to purchase mobile phone batteries by pressing the circular arch point, and directly with your fingers and feel the soft and hard levels of the conjugate point. The combination of genuine mobile phone battery point texture is relatively soft and flexible, when the battery is inserted into the phone, the elastic suitable locking stability; On the contrary, poor battery becomes more jerky texture of some, the battery installation, not easy to smoothly, according to the hp Business Notebook 6715b battery , hp Business Notebook 6715s battery slot.
5, charging on the identification of
In general, the superior performance of the cell phone battery, an internal over-current protection device, once the external short-circuit the phone, give rise to significant impact on current, the overcurrent protection device can automatically cut off the charging circuit in order to avoid cell phone batteries due to high current the impact of the phenomenon of the event of damage or burning. The bad battery is likely that there is no over-current protection devices; this lengthy battery charging, the battery shell may appear the phenomenon of boiling, the worst case, smoking behavior may occur. If the battery charge did not take long, hot phenomenon appeared, then the likelihood, the battery is defective.
The need to remind consumers that the mobile phone battery warranty should be at least six months, during which the event of quality problems, you may ask for contact returned to the dealer to maintain their legitimate rights and interests.
The following are some well-known brand or model of battery purchase the application skills and knowledge in maintenance of cell phone batteries, could you provide some help:
Mobile Phone Battery Maintenance common sense:
1. In order to extend battery life, battery charging time is normally no more than the necessary charging period (5-7 hours).
2. Only when the manufacturer first wife purchase the charger.
3. The battery contacts are not with the metal or contact with grease fittings, pay attention to moisture.
4. Battery Do not immerse in water or throw in the fire.
5. Battery Do not put objects in low-or high-temperature side, such as refrigerators and stoves.
6. Dealing with the battery, please use the special facilities.
7. To replace the battery, use only approved battery type of phone.
8. For the memory effect of battery, each battery should be used up, and then recharge. Otherwise, the battery memory effect occurs, greatly reducing the battery life.
9. Battery life is based on charge-discharge cycles to calculate and, therefore, adequate electricity, run out of power, maximize hp Business Notebook 6710b battery , hp Business Notebook 6710s battery life. -
Three third-party laptop battery problems
2009-09-30
● Third-party laptop battery Security:
Earlier, the laptop battery door" events has created a hubbub. In August 2006, they heard a certain brand of laptop battery problems prone to fire and may burn the whole laptop. August 14, 2006, the brand recall order was issued in the United States announced 410 recalls notebook batteries may cause fire, saying production of defective battery supplier.
Subsequently, the supplier acknowledged the statement and said: battery flawed mainly due to the production process contains a mix of small metal fragments, these fragments led to the battery charging dell Inspiron 1721 battery,dell Inspiron 2600 battery system and computer contacts short-circuited, causing overheating or explosion.
Subsequently, the major brand notebook makers have to have the defective laptop battery recall order was issued, and made for the matter of compensation to consumers.
"Battery Door" event to enable consumers to re-understand notebook battery - if the laptop battery quality problems exist, is likely to burn the whole laptop; if we use the original notebook battery, the battery can lead to accident compensation .
For consumers, safety is always the most important, followed by unexpected is the product when the compensation package. If I use the original notebook battery, then either burn the battery alone, or the battery lead to the whole laptop was totally destroyed, I can get from the laptop manufacturer for compensation. However, if I use a third-party laptop battery, then when the accident occurred, it is difficult to find a fairly clear compensation package.
Thus, for third-party laptop battery, how to ensure the safety of such products, how in the event of an accident to provide a reasonable compensation package is absolutely the greatest concern to consumers.
● a comprehensive third-party laptop battery dell Inspiron 2650 battery,dell Inspiron 5150 battery:
Die variety of notebook computers, notebook batteries die naturally varied. Solely from our recent evaluation prototype of the notebook off, you can pick several different styles of the laptop battery dies.
If you want to operate third-party laptop battery, and would like to become bigger and stronger, of course, can not rely on a single species, at least to achieve "coverage of all popular notebook computer" level. However, the development of laptop battery dies it takes a lot of money, which is "Why are long-standing third-party laptop battery has not been a" main reason.
Thus, for third-party laptop battery, how to ensure the comprehensiveness of the battery dies, but also a major issue of concern to consumers.
● the need for third-party laptop battery:
The last problem is the need for third-party laptop battery. Bluntly, that is - not only the original laptop battery with high security, but also in the unexpected when it comes to compensation, and there is no "mold type of failure" problem, then why do we need to purchase third-party laptop battery it?
At present, the original laptop batteries generally have higher prices, in addition to a very few brand laptop batteries other than the price of 300 yuan, the price of most brand laptop batteries have been around 600 yuan, and some brand laptop battery even more than the price of 1,000 yuan .
We specifically for this issue inside the company did a survey of my colleagues are basically the answer: "original laptop battery price is too high, in order to increase endurance time to buy a battery asking too much, if the price is cheaper, then I'd would consider buying a few pieces to prepare for contingencies.
Can be seen, only the price of third-party laptop battery cheap enough to arouse the desire of consumers to buy, which is decided the key to the success of third-party laptop battery problems.
● Summary:
First of all, we must recognize the value of third-party laptop batteries, laptop batteries because the original price is too high. Secondly, we hope third-party laptop battery to properly handle security, comprehensiveness and the need for these three issues. Finally, we would like to see massive numbers of visitors for the third-party laptop dell Inspiron 6000 battery,dell Inspiron 630m battery view. -

Massachusetts Institute of Technology scientists have developed a new battery materials, processing technology, can be used to create smaller rechargeable Sony laptop battery, its charge-discharge rate is expected to be reduced to minutes or even seconds, rather than hours.
Li-ion battery is a small mobile phones and other electronic devices, one of the most commonly used power, they have a very high energy density, very good at storing energy, drawback is that charge and discharge slowly.
Scientists generally believe that, resulting in slow Li-ion battery charge and discharge the reason is responsible for carrying charge lithium-ion sony PCGA-BP1N battery,sony PCGA-BP2E battery materials through the movement is too slow. However, scientists at Massachusetts Institute of Technology discovered a few years ago, according to computer model forecasts, common battery materials, lithium iron phosphate in lithium-ion velocity should be very fast.
After further calculations, they found that lithium-ion only through the channels on the surface of this material quickly into the material, that do not directly face the difficult passage into the material of lithium ion inside, because they can not exercise to the channel entrance.
Massachusetts Institute of Technology research team in the battery of this surface to create a new type of structure, so that lithium-ion movement in the surface quickly, just like an automobile along the "ring road" to high speed. Movement encountered a lithium-ion channels, they will immediately enter the cell materials.
They used this technique to create a piece of the battery, its charge and discharge rate of only 10 seconds to 20 seconds, compared with untreated material of the battery needs 6 minutes to fully charge and discharge. In addition, the use of new technology made the battery charge and discharge in the case of repeated failure slower.
Scientists say the technology could greatly reduce the cell phone and laptop sony VGP-BPS2A battery,sony VGP-BPS2B battery,sony VGP-BPS2C battery charging time can be used to create a better acceleration performance electric vehicles. Will be held March 12 issue of the British "Nature" magazine will be published in the paper. -
