Fuel cells and other environmentally friendly hybrid car is more promising

President of Honda Canada and the U.S. Yozo researchers believe that by 2020, fuel cell and hybrid vehicle market share of 5% to 10%. However, many manufacturers, especially Toyota, is even more optimistic about the oil, electricity and future development of  battery hybrid cars. Toyota even said that is not a fuel cell hybrid transitional technologies will be used in all future Toyota hybrid.

 It is reported that the use of hybrid electric vehicles can simultaneously store the battery power and internal combustion engines. A battery-driven electric motor at the very start, idle and other unhealthy working condition when the engine work to meet environmental protection energy-saving effect.

 Those who support the hybrid view, this car technology has gradually matured, the market is starting to recognition, such as the Honda Insight, Toyota PRIUS been used for many years in the United States and Japan, selling over 10 million units, a good energy-saving effect , and fail to create the lowest fuel consumption records.

Kami yang 3, do not optimistic that the hybrid can not fundamentally solve the environmental protection, energy conservation issues. Unless oil prices are abnormally high, or hybrid can do very little market appeal.

Since the hybrid dispute, then the fuel cell vehicle technology more than 20 years before maturity, we will use what green car?

A kind of argument is pure electric vehicles, some domestic R & D has indeed been tried in this regard, but a pure electric car market, after all, is limited, Moreover, technically difficult to solve power is weak, charge cycle is long, the old batteries secondary pollution, etc. problem, therefore, a pure electric vehicles can only serve as buses and other vehicles used for a particular purpose.

There is also often present in Beijing, the street will see liquefied petroleum gas (LPG) vehicles and compressed natural gas (CNG) cars, as well as ethanol and other alternative-fuel vehicles. Such cars are based on the traditional engine, for other gas or liquid fuels. This is technically simple and feasible, but can not fundamentally solve the energy and environmental issues. 

The Volkswagen, PSA and other European car company’s proposed program is the promotion of large quantities of modern diesel cars. To this end, FAW-Volkswagen has also launched a special 1.9-liter SDi diesel Jetta sedan, but the diesel cars in China’s development also faces many problems such as fuel quality.   

Kami yang 3 that, in fact, in recent years, major automobile manufacturers and in high efficiency, low consumption, environmentally friendly gasoline engine devoted more energy, after all, gasoline engine in the future for a long period of time will continue to dominate the market.

Abolition of the tax rebate lead-acid batteries reshuffle imminent

Lead-acid storage battery export tax rebate policy has been canceled the past two months, for lead-acid battery industry, created a profound impact. This is to some extent accelerated the industry reshuffle.

Power Co., Ltd., Zhejiang Nandu power lead-acid battery manufacturers last year, sales of one of the top 50 last year, the battery reached 20 million U.S. dollars export volume. The company’s head of International Trade, Wu Han Qing yesterday to the “Daily Economic News” said that the original thought that this policy would at least half a year later introduced, did not expect was so fast, and businesses affected by the larger than expected. Wu Han Qing, said after the abolition of tax rebates, the domestic prices of lead-acid batteries is only 5% lower than in eastern Europe 6%, using low-cost competitive advantage has been obvious, market share will be reduced, business development pace slowed down significantly.
 
Yangzhou Apollo Battery Co., Ltd. has developed rapidly in recent years, the company claimed that from January to August this year, the company lead-acid battery product exports reached 11.29 million U.S. dollars. However, after the abolition of export tax rebate, businesses will reduce the net profit of more than 1100 yuan.
 
Fortunately, due to Shanghai a few years ago, attaches great importance to environmental protection, only a very small number of lead-acid battery manufacturers, exporters on a large scale only one. Delphi International Battery Co., Ltd. is Shanghai’s largest export enterprises, now the company has changed hands to Shanghai kiangsons Battery Co., Ltd.. The company’s situation and the domestic most of the lead-acid battery business is similar.
 
Domestic lead-acid batteries of large enterprises had a hard time, not to mention small businesses with low ability to resist risks, in the current international battery manufacturers advantages of living in a buyer’s market, the lead-acid batteries of small enterprises will be more shuffling, or merger.
 
So far in September, the International Lead demand increases rapidly, prices are also sharply higher. Since the second half of 2003, the domestic price of electrolytic lead from 4,500 yuan / ton in September rose to 13.8 thousand yuan / ton, while this month, electrolytic lead prices as high as 15,000 yuan / ton. At the same time, the EU also harmful substances in the battery to be strictly limited, that technical barriers to trade will also have the domestic exports of lead-acid batteries to face more severe test.
 
AQSIQ, experts have said the cancellation of export tax rebate will make the battery much smaller profit margins of enterprises, to a certain extent, accelerate the merger and reorganization among enterprises, as well as the battery industry re-shuffling.
 
At present, the domestic battery producers as soon as possible get rid of “creating a profit on the export tax rebate” concept, appropriate reduction in price competition is relatively intense exports, development of new applications and markets, and even consider establishing manufacturing bases overseas.

China Lithium Battery Patent Battle

The article comes from http://www.mylaptopbattery.co.uk/blog/2009/09/03/china-lithium-battery-patent-battle/

In the first half of this year, this newspaper since 3114, the four successive interest of the University of Texas and its commercial mandate Hydro Quebec, Canada, Phostech alleges that the U.S. battery maker A123 (GEM), Inc., Vaillant (Valence) Company Infringement lithium iron phosphate patent dispute. This series of reports have caused widespread concern outside the industry. Today, lithium HP laptop battery?iron phosphate batteries on the topic of the patent once again affects the electric car industry’s nerves, but the protagonist of the incident replaced by China.
Lithium iron phosphate in North America patent litigation battle it, when a lithium iron phosphate battery patents to defend the war broke out in China.
DVD patent pool in order to avoid recurrence of this tragedy, our country more than the battery companies and research institutions are positive actions, to collect evidence to prove that Hydro Quebec and the French research center in China last year, the application of carbon lithium iron phosphate-layering technology patents ( Phostech Canada has been exclusively licensed to the company) is invalid. However, the present situation hp PB991A battery ,hp PB992A battery, the Chinese side want to win, extremely difficult.
■ foreign success in China for carbon-layering technology patents
This year, our electric cars and motive power batteries of the forum is particularly high. In almost every forum, can see the shadow of Canada Phostech company representatives.
Not long ago, the fourth South China Lithium Power (International) high-level Technical Forum held in Shenzhen. Made a special trip from Canada came to participate in the forum Phostech Rice, CEO? Toston smiling. After the introduction of products and technology, Toston answered live audience on the patent question. He said: “In the United States, the Tribunal intends to recess for some time to continue to hear from companies such as our A123 lithium iron phosphate battery patent dispute. Last December, the European Patent Office rejected the Phostech the company’s lithium iron phosphate battery patent application . We intend to continue to apply for patents, is expected to be approved in 2010. In addition, in Japan, we are also actively apply for a patent. ”
Toston talked about Phostech companies in the United States, Japan and Europe patent applications received, but did not mention China, and I wonder if the wish to avoid. According to report, in 1999, the French scientific research center, Professor Michael? Oman and Germany invented the carbon-layering technology, solves the conductivity of lithium iron phosphate materials, poor problem. Subsequently, from Hydro Quebec and the French Scientific Research Center have applied for the patent. In 2008, the two institutions in the Chinese patent application is approved, the patent has been the exclusive right to use license to the Canadian Phostech company.
Seize the high ground in the patent, after, Phostech actively explore the Chinese market. Currently, the company has opened an office in Shanghai. At the same time, its high-level frequent appearances in China, and actively promote the company’s lithium iron phosphate batteries and materials hp PB994A battery ,hp PB995A battery.
■ two patents can not bypass
Li-Quan Chen Chinese Academy of Engineering, told reporters in the lithium iron phosphate batteries and material field, there are two core technology patents is impossible to bypass, one of which is the layering of carbon technology patents, and the other is the carbon-thermal reduction technology patents. The former has applications in China, the Canadian company has the exclusive right to use Phostech; the latter owned by the United States Viagra can be company, has yet to apply for a patent in China. However, Viagra can be company has set up two companies in Suzhou — Vaillant Technology Co., Ltd., Takeyasu Energy Limited, are responsible for the production of lithium iron phosphate materials, and battery production. In order to seize the Chinese market, Viagra can be company does not rule out the patent on the trivial.

Academician Li-Quan Chen also told this reporter in a surprising thing: It turned out that Viagra can be company owned by the carbon thermal reduction technology patents, is entirely his students — Dong masterpiece.
In 2000, Dong switched from a Canadian company to enter the United States Vaillant, serving as a senior research fellow. Prior to that, he has been the French National Research Center for Condensed Matter Physics Institute of Chemistry of Bordeaux and received a doctorate and post-doctoral study in the United States. In Vaillant’s work, Dong fully demonstrated the Chinese people industrious, intelligent character in just six years, he helped Vaillant companies in 28 countries around the world applied for the patent materials, lithium iron phosphate (Dong is the inventor , the property Vaillant companies hp PP2182D battery ,hp PP2182L battery).
However, things are unpredictable, Dong was perhaps never imagined that today, these patents would become the Chinese battery enterprises to enter the field of lithium iron phosphate battery barrier.
“At that time, I can think of their own materials, lithium iron phosphate formulations and preparation methods are written out and apply for a patent. Some of the patent, Viagra can be company already has the appropriate technology at that time, and others are under development, There are simply not begun to study. This series of patents is very tight, almost covering the manufacturing aspects of lithium iron phosphate battery is indeed hard to break. “talking about past events, Dong told this reporter.
■ want the patent is invalid, the Chinese side little chance of toppling
“In the lithium iron phosphate batteries and materials, China has absolutely can not be called art. A small number of corporate patents, said there is no problem, it is nonsense, and there are many complex issues to be resolved. If we say that, for the University of Texas and the A123 Corporation Lithium iron phosphate between the patent dispute, we are somewhat indifferent manner of taste, then, this time with the Phostech companies in China to obtain the carbon-layering technology patents, as well as companies such as Viagra can seize the Chinese market, speed up, patent issues very realistic placed in front of us, not be evaded. “a company official said the battery hp Pavilion DV1000 battery ,hp Pavilion dv2000 battery.
It is aware of this, these batteries before businesses and relevant research institutions together to gather evidence, look forward to tear down barriers to multinational patents.
State Intellectual Property Office a staff surnamed Wang told reporters, “Patent Law” Article 22 clearly provides that a patent application at least have novelty, creativity and practicality, and there is no other substantive issues in order to be authorized. By the same token, if you want the patent invalid, the State Intellectual Property Office shall review committee to pursue the invalid request has been authorized by the patent to prove there is no novelty, inventiveness or usefulness. If rejected, you need to bring an action through the legal channels to resolve.
The staff member also said that the best means of proof is to find a one or more previously public documents, and to compare the patent claims, if the overlap, you can prove that the patent lacks novelty. Corporate sources, and now they have found an open literature, but the arguments are not particularly strong. Once the proceedings, the odds are not great.
Chinese Academy of Sciences Institute of Physics, doctoral tutor Huang Xue-Jie said, after the U.S. Japan’s NTT paid 30 million yuan (equivalent to RMB) settlement, the only solution of the lithium iron phosphate material patent disputes. Many enterprises in Taiwan is to spend money to buy other companies to Phostech the right to use the patent. “If in the end, China and Japan, companies have to embark on the road to spend money on patent licensing, which is China’s iron phosphate lithium battery manufacturers would be a bad news, but also a sad thing hp Pavilion DV4000 battery ,hp Pavilion DV5000 battery ,hp Pavilion dv6000 battery.”

Freezing method can do repair laptop battery

The article comes from http://www.mylaptopbattery.co.uk/blog/2009/09/02/freezing-method-can-do-repair-laptop-battery/

Books bought in April 2004, when the laptop battery can only be used 40 minutes, and after almost a year of use, performance, good books, but the battery can only uphold the 10 minutes of. According to jar the depth discharge method, I have poor battery more terminal one, even if the power shortages and a serious shortage of warnings can only be completely closed to maintain less than 8 minutes. My HP laptop battery has become legendary in the body.
Practical problems placed in front of me: for the core, or replace the battery, not a moment to decide, usually very few battery when the things that delayed down. Until one day, by chance I broke into a Hong Kong mobile phone forum, saw a revival of the method for mobile phone battery, anyway, I think the battery has finished on the dead horse a living horse doctor bar. 5 days later, my battery reborn.

First, remove the battery from the books, obtain other a newspaper. What, no, can not it, quickly ran downstairs to buy a bar. Hey, toilet paper can also be. Roll up a newspaper to put the hp 367759-001 battery ,hp F2024A battery dead.
The next step is carefully put the battery pack is good, pay attention: Be sure to tightly wrap, remember, remember. The purpose of a newspaper for a while to tell.

To rent a suitable volume of plastic bags, newspaper or toilet paper would be a good battery pack into them, excess release pockets of air, with wire or rubber band fasten pocket.

It is a critical step, and open your refrigerator freezer door, your masterpiece into the minus 5 degrees of frozen box. This time, after you waited patiently in the closing 72 hours, what, you do not know 72 hours is how long? Yun Si, that is, three heavens. This time, you know the newspaper because of the use of the bar, that is, to absorb excess moisture, plastic bags are sealed to prevent outside moisture stored into.

3 days later, remove the battery, remove the plastic bags and newspapers, at room temperature for 48 hours which is two days after the charge on the machine. Wow, a miracle, my battery can insist that 1 hour and 18 minutes, and 78 minutes Yeah, my mother, my God. My battery finally alive again.
In this experiment the same time, a IBM600E battery, a Canon S100 digital camera batteries and a battery-Lucent PHS has been tested and all of them.
But later, after a few freezing, the battery completely back to the original state, so freezing lithium batteries can not be repaired hp F4812A battery ,hp HSTNN-LB31 battery ,hp Pavilion ZV6000 battery.

Microbial fuel cells a new direction

The article comes from http://www.mylaptopbattery.co.uk/blog/2009/09/01/microbial-fuel-cells-a-new-direction/

Tsinghua University, China University of Pennsylvania and the latest research shows that bacteria can be dirty salt water into drinking water and electricity.
The study made clear the development of a microbial fuel cells laptop battery a new direction. In the past, microbial fuel cells are often used to generate electricity or hydrogen or methane in the form of stored electricity.
According to the Discovery Channel reported that the University of Pennsylvania scientist Bruce Logan (Bruce Logan) said that the microbial fuel cell can be organic waste into energy source acer laptop battery. Logan and other authors in the “Environmental Science and Technology” magazine (Environmental Science and Technology) published a related paper. Logan said: “In this latest discovery, we believe that by changing the micro-power generation, we can deal with salt water for desalination.”
The researchers first from ponds or other natural water samples collected. Millions of micro-organisms in the sample, some bacteria (scientists have yet to ascertain the type) will be automatically generated within their cells, electrons and protons, and they are transferred to in vitro. Other bacteria will absorb these electrons and protons, as the creation of hydrogen, methane and other chemicals such as acer Aspire 1690 battery，acer Aspire 1300 battery energy material “fuel.”
The researchers found that the use of two specially designed plastic film to take advantage of the energy generated by these organisms. This film can be produced by microorganisms isolated electron, ion, or gas, allowed to flow to the cathode or anode, respectively. Cathode, anode and membrane assembled in a small tissue box, as the same transparent plastic box. Between the film by adding a cup of pond water, bacteria start and, ultimately, can produce up to 90% purity of water.
The purity of water can be based on scientific or commercial needs to be adjusted, or even up to drinking water standards. Microbial fuel cell can be removed in the water most of the salt, because the process can reduce power consumption, it can also reduce the cost of water desalination.
The same is also studying the microbial fuel cells, Oregon State University, Liu (phonetic) said: “No matter how the treated water salinity, which will be the first time the human microbial fuel cell used for desalination acer Aspire 1410 battery，acer Aspire 5560 battery.”
Liu said: “Using this method, basically do not need to input energy; if artificially added to the cells in the organic material they can even produce energy.”
At present, both the dilute salt water to produce electricity or produce hydrogen, methane or other gases, microbial fuel cells are restricted to the laboratory. This situation will change next month, Logan and his colleagues at a winery near the installation of a large-scale microbial fuel cells, plans to produce wastewater into hydrogen.
Logan said: “At present this is only a demonstration project. But in the end wineries will be able to use the power generated by microbial fuel cell-driven cars, forklifts and other vehicles.”

Activate the “aging” laptop battery

The article comes from http://www.mylaptopbattery.co.uk/blog/2009/09/01/activate-the-aging-laptop-battery/

To show the battery is damaged. Therefore, the laptop battery maintenance and rehabilitation needs of laptop users is the topic of concern. Maintenance process is also often referred to as “activation”, “activation”, a very vivid and to reflect that the acer laptop battery “dead” and rebirth process.
I summed up the activation of a battery approach, its basic principle is that when the charge and discharge currents must be small (but not too small, or too long), there is to try to be filled, put completely. Cell damage because the battery in use after a period of time will “aging” of. Concrete expression of the resistance is bigger, at charging time at both ends of voltage rise faster, so it will be easily found for the charge control circuit has been filled, the capacity also is naturally “down”. Since relatively large battery acer BTP-42C1 battery，acer BTP-43D1 battery internal resistance, discharge voltage drop by high speed, the system can easily mistaken for a voltage not enough, lack of electricity (in fact, there is no electrical discharge).
As can be seen from the above description of the battery is a vicious cycle of aging process, the discovery of lost working hours, the battery faster than when what it should be tempered, or else it will be finished sooner or later. In addition, many lithium battery failure is the battery package of a certain energy-saving result of core failure, a bad pot of soup mouse droppings. This phenomenon can not be avoided, because the battery power-saving core of each character can not be fully consistent with a long time there are some quality, the aging first weakened, undermining the whole (series after) the discharge curve. It simply means that section of bad batteries before charging full discharge also finished first place, but this time the capacity of the other batteries have not been fully utilized.
The core of a power-saving over charge / over-discharge will not cause the battery monitoring circuit that the whole is full of / discharge end of the. For example, when charging other batteries start getting close to full charge when pressed, that section of bad batteries may have reached the terminal voltage of 4.30V or higher, resulting in overcharge damage, while others are sufficient dissatisfaction. Editor’s note: For internal batteries battery damage, the “Chinese computer education” 2001 No. 2 has a very good article - “notebook computer batteries DIY” worth learning from. Interest, courage and capacity of friends can try to open the battery pack, believe that the help of multimeter, you can quickly find the damaged batteries (voltage abnormality). If conditions permit, according to the corresponding parameters of the replacement batteries can be qualified product. The battery charge and discharge lithium-ion battery charging poses as a way of fast charge constant current in the voltage reaches a certain value and then to slow charging constant voltage mode. Notebook computers are often not strictly a constant-current charge of monitoring devices acer BTP-44A3 battery，acer BTP-52EW battery.
The system load when a large charge current on small, whereas the large, the current from the AC power adapter power margin decision. Clearly, the system will charge the battery and other components, such as CPU, hard drive, LCD and other competing energy sources. I tried to run side Superπ, while charging the way and found that the charge current in the 0.70 ~ 1.70A between the changes, can not meet the lithium-ion battery charging requirements, so I fear that this will work, rechargeable batteries were defective. IBM statement calling for notebook computers will not operate when the charge is probably the reason. Charge at boot time, if we can select the charge mode, you do not choose fast charge mode (Express charge mode), to avoid premature battery “full.”
There is a time of low battery power to prohibit the use of the highest CPU performance in order to reduce the power of the competition. If the notebook computer’s CPU is to support the use of SpeedStep technology, it is best to install the driver (the vendor will be responsible installed) to facilitate the adjustment performance. SpeedStep program icon is a blue flags, right-click performance tuning options it can occur. Under the Windows XP system, SpeedStep program will be problems, this time to rely on or to modify the BIOS parameters of the regulation of a number of brand-specific programs, such as IBM notebook computer software is very powerful tool.
Electric-discharge of lithium, or always-on, let the natural discharge better acer Aspire 1680 battery. Is best not to use physical methods (string of resistors in the class). Not to say that that was not feasible, but relatively large risk, if the internal protection circuit was not working, then set aside the batteries, and the worst is probably the battery explosion, of course, this unlikely. Circuit hidden dangerous is not impossible, a number of big-name manufacturers have found that the design of potential risk factors exist in a battery recall, as mobile phone battery when you do not hear the explosion.
Small knowledge:
In general, notebook computer battery protection circuit in the part is usually voltage block, control chip, insurance, and temperature probes. Temperature protection device is usually a one-off, the inside has a fuse (some 130 ℃ Fuse), is used to monitor the voltage regulator block work. If the charge-discharge process exceptions, immediately there will be a current through the temperature protection device, will fuse fuse, the battery’s internal circuitry at this time for the open circuit state, and can not be restored. If you want to repair only the replacement of temperature protection device, but such temperature protection device on the market hard to find. Discharge is the discharge current as small as possible, the operation is to slow down and let the CPU, hard disk stops turn, transferred the darkest the screen (or close the switch off), then do not run any programs until the laptop automatically shut down. The emphasis on small-current discharge is to prevent premature detection of laptop battery shortage. I have disabled the hard disk, close the screen, cancel the power of the state police under the laptop completely discharge (put a close to 6 hours), the battery acer BTP-58A1 battery，acer BTP-59A1 battery，acer BTP-60A1 battery，acer BTP-63D1 battery，acer BTP-73E1 battery capacity from 31.72Wh restored to 33.65Wh.

Dell laotop battery usage instruction

The article comes from http://www.mylaptopbattery.co.uk/blog/2009/09/01/dell-laotop-battery-usage-instruction/

Notebook laptop battery is a more important component, its state is directly related to the notebook computer in the absence of the power of the environment the ability to work, so the correct use and maintenance of batteries is necessary. Laptop battery is a form of consumables in the use of a period of time, will begin to age. Original Batteries as a physical work environment factors susceptible to influence, but the main reason leading to cell loss is caused by oxidation of the DELL laptop battery internal resistance to increase, even if you do not set aside the battery, it can only be a certain degree of delay loss rate of the battery only. Therefore, the use and maintenance of the battery are a few suggestions:

1. No need to ensure that every time the full release END electric recharge, there is an external power supply conditions should make full use of external power supply;
2. A period of time to do a protection circuit placed under the control of deep-charge battery power to amend the statistics, but it will not increase the actual capacity of the battery dell Inspiron 4100 battery,dell Inspiron 4150 battery;
3. A long time without the battery, should be placed in the shade in order to weaken its internal self-passivation reaction speed; this article Source: Dell Laptop Battery Use
4. Protection circuit is also able to monitor the battery self-discharge, long-term without the battery should be charging to a certain degree of power in order to prevent self-discharge of batteries in storage in the discharge of excessive lead to excessive damage to the battery.
In addition, according to our information the battery manufacturer, Dell notebook battery charging protection measures have improved in 95% of electricity that is used trickle charging, the battery is full will no longer charge after that there will be no overcharging phenomenon. In addition, because the battery life is fully charge and discharge cycles to calculate, not simply in order to calculate the number of charge cycles (fully charged battery to completely run out of this be considered a charge-discharge cycle), not on reducing the battery life on one charge one tine. Therefore, the battery should have been inserted in a notebook is the right to use the above method, and will not affect dell Inspiron 8000 battery,dell Inspiron 8100 battery,dell Inspiron 8200 battery life.

How to play laptop battery greatest potential

The article comes from http://www.mylaptopbattery.co.uk/blog/2009/08/30/how-to-play-laptop-battery-greatest-potential/

 Activation of a new battery
Does not require the laptop battery for 10 hours of rechargeable battery to activate the activity of the normal charge-discharge method for activation.
The proposed method: According to the available information suggests that the activation of cell work should be completed at the factory, and DELL laptop battery factory with a capacity of some natural wear and tear in order to avoid damaging the battery. Activation of the battery should be in no circumstances to protect the circuit can be with its own lithium battery circuit protection circuit, the purpose of this piece of the circuit is to avoid excessive battery charge and discharge, generally filled with the battery after charging when the indicator light off , the battery can not be recharged into the electricity, and then you then plug the power plug to recharge the battery in the face of what use? Available from the battery can be seen on the status of the battery have any charge, another teaches you a simple way to be able to determine whether there during the battery charging, battery charging, when the phenomenon will have a fever, when the battery is full after one hour (power plug does not pull), you go try the battery to see if the battery is still warm not hot? The result is definitely cold, because the battery is not charging and discharging state certainly does not heat. Notebook makers at the factory will propose that a new battery for more than 10 hours. The author of this opinion, should be taken into account that some notebook manufacturers a new user in the new battery charge when not fully grasp the skills, simply so that they can directly charge 10 hours, so this should be the business of expediency dell FK890 battery,dell GK479 battery.
How to correctly charge
Most people said that the unnecessary use automatic shutdown and then charge, and do not arbitrarily charge. Are generally used when the battery needs charging when the computer prompted further charge, of course, prompts the time can be set, the default is to 3%.
I proposed approach with the majority of the people is the same. In fact, regardless of laptop use nickel-metal hydride or lithium batteries, these batteries are have a memory effect, and nickel-metal hydride batteries with memory effect is very obvious, but equally there will be lithium memory effect, but its memory effect smaller than the nickel-metal hydride Bale . There is no memory effect on lithium to say, only exaggerated and irresponsible business conduct in advertising, is totally misleading. Well, since the battery has a memory effect, it should be noted when charging point, as far as possible and then run out of charge, but do not have to deliberately say must use the computer to automatically shut down, so that although there is no harm in using them (because the laptop battery has a charge discharge protection and automatic shutdown in general has not yet reached notebook battery discharge protection standards), but you do not feel so tired? In fact, less than 3% of the charge in this way is very good, memories will certainly be the effect, compared to natural wear and tear, it should be nothing. As for the charge that they want to charge on the point of view, the author is completely disagree, and have already said, whether laptop battery nickel-metal hydride or lithium, which has a memory effect, if in this way then the battery life will be shortened dell 3R305 battery,dell Inspiron 2500 battery.
Unplug the battery when the external power supply is
Most people use an external power source, will the battery removed, only a few use an external power supply when the battery is placed above, but their brands are used in several international brand.
In fact, if the battery is removed, the conflict focused on the use of an external power supply when the battery is charging to the issue. We should know that the number of charging and discharging the battery life is directly related to the general lithium battery set the number of charging and discharging are fixed number of charge cycles only 400-600 times, specially modified products, but 800 times, once for each rechargeable batteries a step forward to retirement. The first argument is simply because they are afraid to use power, the battery will be conducted on the above charge, not only increase the number of charge cycles, but will also cause overcharge. The second view is that the battery is full power on the computer in the use of an external power supply will not recharge.
In fact, both views have their right side, but also the wrong place. Because it is only the views expressed by individuals is not very comprehensive, after I investigated, many notebook manufacturers are taking into account the vulnerability of the battery, and the product added to the battery protection technology, and thus the corresponding different brand laptop batteries charging protection technology is different, like some large companies do very well in this regard, such as: IBM, Hewlett-Packard, Toshiba, Compaq, etc.. One of the most thoughtful consideration is that IBM, IBM’s notebook computers can detect the battery discharge situation, ThinkPad notebook battery only less than 95% of the time will automatically recharge. This can play a very good protective effect on the battery, and now many other manufacturers have followed suit dell Inspiron 3700 battery,dell Inspiron 3800 battery,dell Inspiron 4000 battery.

 

So, like the battery, you do not have the time to use pull down, because only when the capacity less than 95% of the time it would charge. But even so, if you are prolonged use of computers, or will the battery be removed to compare the good, because the long-running laptop heat generated when the battery will cause some damage. However, some other “little brand” laptop batteries, may not enjoy such treatment, because it has not done inside the battery protection technology. I like to use a certain brand of notebook computers, if the fully charged battery on the above, when using an external power supply was confirmed when the first charge about electricity, because the battery storage, will have wear and tear, can not reach 100%, while not 100% as long as , power supply connected to the charge. Each access to external power supply is equivalent to charging the battery once, although only a small charge will be the time. Therefore propose that we use when the machine according to their own circumstances, look at the laptop manual, choose whether to use an external power supply when the battery removed.

The misunderstanding of laptop battery repeatedly charge and discharge deeply

The article comes from http://www.mylaptopbattery.co.uk/blog/2009/08/30/the-misunderstanding-of-laptop-battery-repeatedly-charge-and-discharge-deeply/

 Notebook computers equipped with original equipment batteries, after a period of time after use, there will inevitably be of standby time. Some users said: “The depth with repeated charge and discharge method, you can restore the performance of the DELL laptop battery, thereby extending battery life,” I think this to be relatively one-sided.

To understand this issue correctly, may start with the battery type used in laptop computers start with. As you know, before 1995 the production of notebook computers are basically nickel-cadmium batteries to power. The battery is in use, if the charge-discharge method is not correct, the battery will have a “memory effect”, thereby reducing the battery’s actual capacity to eliminate this “memory effect” is used repeatedly in the best way to charge and discharge depth way. With the emergence of nickel-metal hydride batteries, battery capacity has significantly improved, but the “memory effect” did not completely eliminate the shortcomings.
In recent years, lithium-ion batteries in notebook computers has been rapidly growing popularity, due to lithium-ion batteries have basically eliminated the “memory effect” problem, it is used repeatedly to restore the battery depth of charge and discharge performance of the method no longer applies. However, lithium-ion batteries why I still appear to reduce the capacity of the problem? The root causes of that situation, is used in notebook computers and the original lithium-ion battery built-in battery management system in the making.
Battery Management: At present, in notebook computers, almost all adopted the “battery management” and “charge-discharge control” two kinds of chip-level management system. The “battery management chip” placed in a notebook inside the chip to store the register of the computer used in the capacity of lithium-ion batteries, working temperature, ID, serial number, charge and discharge status, charging and discharging the accumulated frequency of important information. The data information in the use of the process, according to the actual situation of continuously updated. The battery built-in “charge-discharge control chip,” the most important role is to monitor and control the battery charge-discharge process as a whole and be documented dell C1295 battery,dell GD761 battery,dell TD347 battery.
Charge: Lithium-ion battery charging process of the whole, divided into “fast charge constant-current” and “constant-voltage charging current decreasing,” two phases. The so-called “constant-current fast-charge” means a charge has just begun when the charge current is fixed and the charge voltage to follow the battery terminal voltage gradually increased until it reaches the nominal voltage charging. When the battery terminal voltage has reached the standard value, the control chip will be automatically transferred to the “Constant current charge decreasing” phase, this time charging voltage will no longer continue to rise, while the charge current is to follow the battery capacity is rising gradually decreasing and finally reached zero, and so will complete the entire battery charging process.
In the meantime, the process of charging the charge arising from voltage, current, time and other data curves will be recorded in the cell are known as “charge-discharge control chip” in memory. “Battery Management IC” is through the retrieval of these data, and is calculated by sampling data such as battery capacity, which is what we read in the Battery Information where the value of Wh.
Fixed: After repeated charging and discharging the battery after use, its built-in chip in the charging and discharging of data will of course change. If at this time “battery management chip” has no chance to re-read the newer, more complete data, it calculated battery capacity would of course not accurate, and to the user the impression that the battery capacity has decreased, but the reality on the battery capacity and there is no real reduction in the actual. Some brands of notebook computers comes with charging management software works, that is, the process of charging Refresh “charge-discharge control chip” in memory of the data, thus ensuring the “battery management chips,” the correctness of calculations.
If you take a close look over the use of laptop computers instructions, you will find among them the “computer in use one month later, the battery should be to make a full charge and discharge operation” instructions. Its main purpose is to use the depth of charge and discharge a way to modify the charge and discharge control chip registers inside the curve data, so that the battery charge control and the nominal capacity and the actual situation of the battery corresponds to arrive at the correct battery capacity values dell HD438 battery,dell KD186 battery,dell GD761 battery,dell Y9943 battery.
