In recent years, with new lithium-ion secondary battery in top sports energy, environmental protection, security and other lithium breakthrough technology industrialization of electric vehicles entered an important phase of development. August 25, 2006 Lithium power ion battery technology and industrial development of the international forum held in Beijing, Zheng Ji-chun, deputy director of Beijing Municipal Science and Technology Committee briefed the participants on electric vehicles in Beijing and lithium-industry developments ion battery. hp Pavilion dv2000 battery  hp Pavilion dv6000 battery

 

Development of electric vehicles is required

 

Zheng Ji-chun said that in addition to global energy crisis, the background, development of electric vehicles in Beijing there are two main reasons, namely, the requirements of environmental protection and the Olympic requirements.

 

According to statistics, from the end of June this year in Beijing reached 2.73 million motor vehicles to maintain, primarily in China, with an annual growth rate of about 15% is expected of By the end of this year will exceed 3 million euros. With the amount of car ownership has increased year by year, commuting from his people very practical at the same time, has also caused environmental pollution, noise, oil tight and so on. According to the experimental units, each fuel vehicles daily gases emitted about 0.6 ~ 0.9 kilograms, the atmosphere in Beijing more than 70% of oil, over 60% of nitrogen oxides from exhaust from cars, direct discharges of pollutants from car the total concentration of the contribution rate has shown an upward trend. Compared with foreign countries, emissions from motor vehicles in China caused by air pollution is much higher than the United States, Japan, France, automobile exhaust has become the capital of main sources of air pollution.

In addition, the 2008 Olympic Games will be held in Beijing, according to his previous experience in successfully hosting the Olympic and pure electric vehicles have become the host city for the Olympics earlier promotional theme of Green Olympics. In 1996, the United States Olympic Games in Atlanta, has invested more than 250 vehicles from golf carts electric and 15 electric buses in the fleet composition of the green, the Sydney 2000 Olympics, has invested $ 400 pure electric vehicles by the composition of the fleet green 2004 Athens Olympic Games in South Korea Hyundai offers a number of vehicles, pure electric vehicles for the marathon and marathon relay of the torch lead car. Solemn commitment of the Beijing Olympics would be “tight control of exhaust gas from vehicles and other sources of emissions of pollutants and the urban daily average concentration of major pollutants to ensure that weather conditions over unfavorable to achieving the standards of air quality required by the International Olympic Committee.”

 

Zheng Ji-chun said, according to these reasons, Beijing has the responsibility and the need to develop electric vehicles is a difficult and urgent.  IBM ThinkPad X60 battery FRU 92P1141

 

Pure electric vehicles will be used for Beijing Olympics

 

According to Zheng Ji-chun erected the development of Beijing Electric Vehicle fundamental objective is to reduce automobile pollution, adjust and improve the structure of energy consumption and to achieve urban economic development, social and environmental development. To this end, the development of Beijing electric vehicles throughout the deployment of a three-pronged: First, select the bus to promote the use of electric vehicles as the main areas, the second is to promote research electric vehicles, development and industrialization, third battery of active power, etc. advanced technology vehicle research and development.

 

Use of electric vehicles in the Olympic Games, Beijing has also made a corresponding development plan: First, 90% buses and all municipal regulations (environmental and postal) car for the electric vehicle, the second is research and development of pure electric vehicles to improve traffic pollution, three Olympic Park with a zero emission vehicles and ultra-low emission vehicle.

Zheng Ji-chun said, according to the presentation of preliminary ideas for pure electric vehicles as the representative of the zero-emission and ultra-low emission vehicle, it will direct the Beijing Olympics, applied to the major bus lines , focusing on regional and sports centers. To this end, Beijing attaches great importance to electric vehicles in recent years, research, development and promotion application. It is understood that, “15″ period, Beijing took the 863 “national” plan major projects in pure electric vehicles, electric buses and bus research and fuel cell development tasks, and became the National Science and Technology has established four model cities in the world of electric vehicles. Science and Technology Commission of Beijing Olympics is also used in the development and application of electric vehicles, one after another in this area, science and technology funds invested around 2 billion euros, thanks a series of major scientific and technological projects and scientific and technological projects carried out much work, research and development, manufacture, application to promote the three links in the detail and meticulous deployment.

According to reports, the search for electric vehicles and development process, Beijing has made a series of technical achievements with the rights of independent intellectual property, access to more than 20 patents, developing technical specifications and standards of undertaking of 22 items related companies have independent intellectual property rights produced electric vehicle capabilities, and Beijing R & D of electric vehicles has almost reached the practical level. A number of lines through a model for nearly a year to run the Beijing developed independently of the overall performance of the electric passenger car pure principle has been found practical electric vehicles and key components of the reliability and applicability of the problem was basically solved, the mileage intervals were failure to reach the level of conventional engines, internal combustion, can basically meet the bus and use requirements during the Olympic Games.

 

Lithium battery car problem solving Olympics

 

Electric vehicles are crucial cycle of battery life, safety, cost and application problems efficiently. Electric vehicles in Beijing in the development and commercialization process has also been confronted with these obstacles, the battery technology for power, performance and cost constraints become an issue of wide application of commercial electric vehicles of the neck strangulation.

 

According to Zheng Ji-chun, at present, Beijing, developed mainly in the location of production of electric vehicles, lead to greater capacity, battery acid and lithium-ion batteries as power, fuel cell technology fuel is still at the track and the stage of research. With the trial operation in a number of bus routes and found that the use of lead acid batteries for electric vehicle driving range is shorter lifespan is short. In addition, lead acid batteries, there are still bulky, not environmental protection and other shortcomings. And compared with lead acid batteries, lithium-ion battery is a high energy density, high operating voltage of the green cells is considered to power future electric vehicle battery, one of the best choices, but the high cost of investment of time. It is understood that an electrical bus with 400-an-hour lithium-price ion battery to hundreds of thousands of dollars to reduce the cost of lithium-ion battery is an important element of future research.

 

Beijing attaches great importance to the lithium-ion battery and key material for research and industrialization. It is understood that, “15″ period around the lithium-ion battery research and development and implementation of the Science of Beijing Municipality and Technology Commission has invested more than 4000 million science and funds technology, organization and implementation of lithium, the material of the lithium ion battery cathode of manganese oxide from industrial technological development “,” pure electric vehicle lithium-industrialization of ion battery research and development ” and a significant number of scientific and technological projects, support the cathode material, the diaphragm and other essential materials to a series of lithium-cell research ion. Thanks to scientific research and technological research on key technologies and development of lithium-ion battery Beijing and key materials for the industry has made a breakthrough. Current cathode materials have been developed with intellectual property rights independent of the lithium-ion batteries key information necessary for the synthesis of manganese oxide lithium technology to solve an international structure of lithium manganese spinel oxide the synthesis of key technical problems and the lithium manganese oxide charge and discharge cycle stability of the world with problems of poor technique, and has made lithium oxide and lithium manganese oxide industrialization cobalt material.

 

However, Zheng Ji-chun also emphasized that lithium current China-materials separator ion A1060 M8403 battery necessary to rely solely on imports, prices cost high-powered battery separator materials represent over 30%. If the membrane material to enable location will significantly reduce the cost of battery power. For example, the Olympic 400 with an electric car when the lithium-ion battery, divide the cost accounted for 16 million yuan, if the membrane to allow localization costs will save half of the membrane. Currently, a number of units are organized scientific research, and some have already entered the pilot phase.

Li-maintenance errors ion battery doubts

 

Notebook battery is something more important, its status is directly linked to a mobile environment in the absence of power in the ability to work. Batteries for laptops is also a major consumer of parts so related to the maintenance notebook battery and wise use are also frequently discussed topic. However, some users maintain some of the understanding is wrong, the following should do something to explain. apple iBook G4 12 inch battery  apple iBook G4 14 inch battery

 

Nickel-metal hydride batteries are now equipped models have basically will not see, the universal application of a lithium-ion batteries. General lithium-ion battery cycle life of 300 to 500 charge-discharge. But this does not mean it can only rarely use the extended life battery. Cells of origin as factors in the physical work environment can influence, but the main reason leading to the loss of cells caused by oxidation of the battery internal resistance increases, which explains why Many users complain that they are fully recharged in use why suddenly had no electricity. It may therefore be understood that the problem is that when the end of the assembly of the battery production line, its internal life, the clock, then start walking, even if you do not set aside the battery, it can be to a certain extent, the loss rate of only delaying the battery. However, in other words, if the battery still sits on the side of the meaning of laptops mobile speak?

 

Material for lithium-ion battery cathode is generally formed by a lithium-active compounds, the negative electrode is a particular molecular structure of carbon. Common Cathode Material for key elements of LiCoO2, charging, added to the PA3285U-3BRS PA3383U-1BRS battery positive pole of electric potential to force the release of compounds, the lithium ions, incorporate negative elements arranged in a lamellar structure of carbon. Discharge, lithium-ion lamellar structure of carbon precipitation and re-cathode combination of compounds. Lithium-ion movement generated a current. Although the principle of chemical reaction is very simple, but in actual industrial production, the practical problems must be considered much more: the cathode material additives required to maintain multiple load-discharge activity, the electrode material If not, who should design the molecular structure of the class to accommodate more lithium-ion battery; fill in the electrolyte between the positive and negative electrodes, in addition to maintaining stability, but also need to have good electrical conductivity, reducing the resistance of the internal battery.

 

Although lithium-ion batteries for low-nickel cadmium battery memory effect, the memory effect of this principle is that the crystallization in lithium batteries will have little reaction. However, the capacity of lithium-ion battery charge after repeated discharge will continue to decline, its causes are complex and diverse. Is mainly positive and negative changes in the material itself, from the molecular level, the positive and negative electrodes of lithium ions on the hole to accommodate the structure will gradually collapse, taken from a chemical standpoint, is the material anode active is passive, there is another side to form a stable compound. Physics will appear on the cathode material to fall off gradually, etc., in short, which ultimately reduces the 346970-001 367759-001 battery charge-discharge process can be free to move many lithium ions.

 

Overload and excessive discharge, lithium-ion batteries will be positive and negative cause permanent damage, from the molecular level of intuitive understanding, an excessive discharge of carbon anode will lead to excessive release of lithium-ion shows the lamellar structure collapsed, over - Rechargeable lithium-ion battery will go too hard in the carbon negative, causing some of the lithium-ion batteries can not be released. Therefore, the lithium-ion batteries are usually equipped with charge-control circuit discharge.

 

Not suitable for temperature, lead to lithium-ion battery inside the reaction of other chemicals that we do not want to see both of the lithium-ion batteries are put in place between the negative temperature-controlled protection by a diaphragm or electrolyte additives. In the battery temperature in a given case, the composite membrane electrolyte membrane hole closed or degeneration, increased resistance of the internal battery until the circuit, the battery is no longer to warm up to ensure that the battery charging temperature is normal.

And loads of deep-discharge lithium-ion batteries can improve the real capacity? According to experts, the answer he did not make sense. Experts say that even the so-called triple full charge-discharge prior to use of “activation” in their knowledge of Mr. Lane does not include this as a need. Why do people provided, however, after the charge deep-discharge capacity of the battery information label will be possible where a change? Will be mentioned later.

 

Notebook Computer lithium-ion batteries are generally the management of the chip and chip load control. What chip running a series of records, there is capacity, temperature, identity, charge state, the values of firing rate. These values are in use will gradually change. Personally believe that the instructions for use in notebooks in the “Use a month should post a full load” approach to a role is now to set those records where the wrong values, making the burden of Battery control and the nominal capacity of the battery match the real situation.

 

Responsible for controlling the main control chip, the battery charging process. Lithium-ion battery charging process is divided into two phases, phase constant current fast charge (when the LED on the battery in yellow) and constant voltage stage down (the battery indicator blinks green. Constant current phase of rapid charging, the battery voltage is gradually increased voltage standard battery, and then transferred to constant pressure in the control phase of the next chip, the voltage does not increase to ensure that no overload, battery current, with the rising gradually weakened to 0, and the ultimate end load.

Statistics smart energy consumption by recording the discharge curve (voltage, current, time) can calculate the battery power of the sample is what we read in the battery information inside World Heritage. Worth. The lithium-ion batteries in repeated use, the discharge curve will change if the chip has not been an opportunity once again read out a complete discharge curve, which is calculated from the electricity that is not true. Therefore, the need to support deep discharge to calibrate the battery chips.

 

A good battery maintenance is required, so many people have asked how to protect a battery but it will not be early retirement for life on this problem. As the battery life is primarily determined by the number of charge cycles in order to avoid frequent use of the battery can be said that one of the most fundamental way, that uses the power of the environment as far as possible does not use batteries.

 

This leads to a question, that is, if energy use when the battery removed from the machine, it is indeed a problem that people in the head. However, the condition of high load and high temperature accelerated the decline in battery capacity. I now invite all imagine that if you do not remove the battery, the laptop because of the role of the charging protection circuit, so that the battery is maintained at 95-100% of the charge state to a high when the battery in which the temperature at least 30 ° C, so if it is hot, the temperature will be higher, so the stability of the supply alternating current, we should try to remove the battery to the using computers. If you are planning a long period does not use batteries, charge the battery to 40% should be placed in a cool place after the save. If the battery is fully charged, will be placed at high temperatures, so that the battery will cause damage. Because load of 100% within 60 ° C environmental conservation, 3 months after the battery capacity has dropped by 40%. Set aside for the preservation of the battery should be at least one month will be used once the battery Zhuangshang Qu, recharged to prevent the loss of activity of the ion.

Similarly, dust and moisture also acts as a battery killer role, they will destroy the circuit of the battery and accelerate the oxidation of the internal battery, so for those of long-term preservation of the battery You can place a layer of thin sheets of low-grade dust and breach of the humidity.

 

In addition, lithium batteries how reasonable prices and dump? As lithium-ion battery that can power a small memory effect is negligible, so it loads half of the injury is not too great, and his fear most is the excessive discharge (full discharge). Lithium-ion batteries often the result of low flow excessive battery can be left in advance, such as bios discharge, discharge procedures, and even connected to the discharge bulb is the best way to do see no alternative but to not try. So, for lithium-ion batteries need not wait until the charging 0%.

 

To summarize, the maintenance of the battery are a few suggestions:

 

1. No need to ensure that whenever a new full release END electric charge;

 

2. A period of time to make a protection circuit placed under the control of the profound power of the battery charge to change the statistics, but it will not increase the actual capacity of the battery;

 

3. A long time without the battery must be placed in the shade to weaken its internal autonomy, the reaction rate passivation;

 

4. Protection circuit is also capable of monitoring battery discharge, in the long term without the battery must be charged to a certain degree of power to prevent self-discharge of batteries for storage in the discharge of excessive lead to excessive damage to the battery.

 

In fact, there is not much to take into account the use of the battery of attention, in other words, is the need did not have much effect. The number of times a cell can use the differences are mainly coming from the battery itself, the making of individual differences rather than use. Choose a reputable brand of notebook PCs is the use of long battery life in the only future of the security.

Rechargeable Ni-MH battery how long charge

 

Depends mainly charger charging current is really spacious. Take note of the charger output current above, for example, 500mAh, 2000mAh Laptop battery should charge for four hours, then add a drizzle of extra hours. This is usually rapid battery. There is also a slow 100-200 mAh rechargeable empathy with the size of the battery capacity divided by the output current can be drawn.

 

In addition, Ni-MH battery memory effect the battery is relatively low, but not the representatives are not, so the best time to recharge completely discharged, then charge. If it is in the use of the battery, then obviously do not use electricity, such as MP3, uses no power of nature will be arrested and charge re-born. This helps prolong life.

 

The use of lithium-ion battery

 

1, how to charge the battery in use for a new lithium battery should be noted that a period of time after the battery is placed into hibernation, lower than normal capacity at this time, the use of time has also come to shortening. However, lithium batteries can easily activated, as after 3-5 times the normal charge-discharge cycles the IBM ThinkPad R51 battery can be activated to restore normal capacity. As the characteristics of lithium, its decision is almost no memory effect. Mobile phones so that users of the new lithium battery in the activation process does not require methods and special equipment. Not only is the theory that, from my point of view practice from the start on using the standard method of charging that “activation” is the best approach. For the lithium battery “activate” problem, many say, is the cooldown should be longer than 12 hours, three times in order to activate the battery. This “The first three load over 12 hours to charge” was obviously the nickel battery (such as nickel-cadmium and nickel metal hydride) inherited from the argument. Therefore, this argument can be said that the beginning a miscommunication. Lithium batteries and charge the battery nickel and discharge characteristics are very different but also very clear to you that I have gone through all the serious official stressed that the technical information and charge-off will discharge lithium batteries, especially lithium liquid Ion causing major damage. According to the standard load and therefore the best time and the standard method of pricing, in particular, do not make more than 12 hours of ultra-long burden. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of pricing. In addition, cell phone batteries or lithium charger stops automatically when the hp 361742-001 battery is full load, there is no electricity nickel charger for 10 hours the so-called “trickle” charge. In other words, if your lithium batteries in full, on the white horse is also sufficient. And we can not guarantee that no one battery charge and the circuit characteristics of discharge protection and will never change and the quality of the safety device so that your battery will be of long duration space flight hazard. It is also d ‘another charge against the main reason. In addition, in some mobile phones, charging more for some time, if they do not remove the charger, this time not only to stop charging system will start to discharge — charge cycle. Perhaps the makers of this approach has its own purpose, it is clear that the battery and cell phone / charger is detrimental in terms of life expectancy. Meanwhile, the charging time should be some time, often at night, but our situation to the electricity grid at night in many places, over voltage, but also volatile. As already said, the lithium batteries is very precious, and more that nickel in the electric charge and discharge aspects of fluctuations in the resistance is much less, if this brings additional risk. In addition, another aspect can not be overlooked is the lithium toshiba PA3285U-2BRS battery is not not appropriate for excessive discharge, excessive discharge of lithium batteries is also very unfavorable. This leads to the following questions.

 

2, normal use should be time to start loading in our forums, often see this argument, because the number of charging and discharging is limited, so phone, the battery should be used as much as possible recharge. But I found one on the charge of lithium-ion battery and Table discharge cycle test, data life cycle is as follows: life cycle (10% DOD):> 1000 Once the life cycle (100% DOD):> 200 times DOD is the rejection of which depth abbreviation. Can be seen from the table in May of depth charge and discharge times, 10% DOD cycle life when the DOD of 100% for much longer. Of course, if the equivalent of actual costs to the total capacity on 10% * 1000 = 100100 * 200% = 200, one full charge and discharge, or better than some, but not before friends say some changes: Under the normal case, you should have a standby battery power is left in accordance with the principle of charging the short load again, but if your battery in your first two days can be expected to persist throughout the day, when they should start on time charge, of course, if you’re willing to back the charger to the office again a different issue. And you need to recharge in order to cope with the communication provided lead busy to come to an important event, even if a lot of apple A1022 battery power over time, then you just charge ahead, because you don ‘are not really lost, “as a” life cycle support is “0.x” times only, and that x is often very low. Short on battery and then filling the rest of this principle is that you want to go to the extreme. And long as charging a widespread view that “as far as possible the cell phone battery power runs out, it is preferable to use automatic shutdown.” It’s really just practice for nickel, the goal is avoid the memory effect occurs, unfortunately, it is also spread of lithium batteries on this. It was too low because the cell phone battery warning appears, still do not charge to continue using the example has been used in automatic shutdown. The results in this case, cell phone charging and starting later in the answer no, should provide review services to clients. In fact, it is because of the battery caused by excessive discharges of electricity at low voltage, so that was not the normal load and footwear and conditions.

 

3 phones for lithium batteries good way to sum up, I lithium batteries used in mobile loading and unloading, the most important recommendations are: (1) in accordance with standards and procedures, charging time, even the first three have to do, (2) when it is weak advice cell phone battery, you should try to start charging a timely manner, (3), lithium batteries do not need ‘ enable the special mode, a battery of standard cell phones use lithium is naturally activated. If you insist on spreading the use of “three previous 12-hour long activation charge” approach, in fact, there will be no effect. Therefore, the pursuit of all super-long 12-hours lithium rechargeable Aspire 3000 battery cell phone use and integration of the practice of automatic shutdown, are wrong. If you’ve already done under the argument wrong, please correct time, perhaps not too late. Of course, cell phones and chargers to protect themselves and the circuit control for good quality, protection of lithium batteries is still guaranteed. Therefore, the burden is central to understanding the rules and, in some cases also may make some concessions. For example, you find your cell phone the night before bed charge, you can also start charging before going to bed. knot of the problem, you need to know what good thing, and not deliberately wrong to do so in accordance with.

 

Battery Maintenance:

 

We know that the cell phone apple A1060 battery is a source of electrical energy, which is the driving force of mobile phone, there is no mobile phone battery is one piece, high capacity, high performance batteries, not only for cell phone long battery life, but also protect telephone circuits to devices that can operate effectively a long time, and vice versa, is likely to cause unexpected damage to mobile phones. For us players, the performance of the battery when the factory, it had already been determined, the size of its capacity, performance, good or bad, are determined by the cell itself and in this regard, we can not man-made changes, but this does not mean that we get the battery after it has produced it should not be done. The use of mobile phones are lithium-ion rechargeable batteries used to store electricity is consumed, need to be added once the feedstock. Do not look down on charge of this aspect of a good shipper and the correct method of load can keep the battery long wait time, but also extend battery life. No more, says mobile phones can also play a protective effect.

 

Methods on how to charge, often in the forum, players will be invited, after a period of actual use and reference, I have summarized the following points:

1. Lithium general factory, manufacturers enable the processing and pre-charge the batteries have more than electricity, you can buy a new cell phone battery is a lithium-ion toshiba PA3285U-3BRS battery, then the first 3 to 5 times charged as a period of adjustment, should be sufficient for more than 14 hours to ensure complete activation of the lithium-ion activity. Lithium-ion battery without memory effect, but a strong inert, should be given to fully activated to ensure that used to achieve best performance. The first charge on this issue, I also consulted the technical staff of Samsung gave me the answer is Samsung original battery, the factory has already been done before the full activation of the treatment, then it does not a long way to activate the charging lithium-ion activity, the first rechargeable battery inside as long as I can be filled after the consumption of electricity. I would like to Samsung’s technical staff should be able to claim convincingly.

 

2. Some automated intelligent rapid charger when the lights change direction, but only said he was full of 90%. Charger will automatically change with the slow loading of the battery is full. Do not immediately cut off the charger, the best should be given to supplement the battery for a while, the battery is fully charged before use, otherwise it will shorten the duration of use. 3. Before charging, lithium batteries do not need to assume, can not fulfill the current production of hp F2024B battery charger lithium is impossible to perform functions, so you can adjust the speed of loading, then suggest that you try to slow Chong Chongdian pricing to reduce the fast charge mode: either slow or fast charge fee of more than 24 hours. Otherwise, the battery is likely to spend long hours of power have an enormous flow of electrons and burning batteries.

 

4. There are many users in charge when the phone open, in the process of charging, the battery side because of the use of mobile phones in landfills, and also because the battery while the assets of Supply disruption of power supply is likely to result in the councils of cell phone circuit will be fever, if an incoming call will result in an instant return current to damage the internal parts of the phone.

 

5. Battery determined by the number of repeated charge-discharge, lithium batteries can continuously charge and discharge of about 500 or so after the battery performance will be significantly weakened, and must try to avoid all batteries I put an end to the rechargeable power, or with the load increase in the battery performance will gradually weaken, the battery reserve time it would be difficult not decreased.

 

6. Do not expose the battery to heat or cold, as a day dog should not be placed on a mobile phone under the sun, and withstood exposure to hot sun, or get air-conditioned room, the air conditioning blowing right places. Loading, the current return, the battery a little fever is normal.

 

7. If the mobile phone battery to attach too long without employment, it is best to call the maintenance department to apply on the drums for an activation treatment, you can own devices with a constant voltage direct current, by adjusting the voltage of 5 ~ 6V, current 500 ~ 600mA reverse battery connector. Note that the liberalization of touch, most can be repeated three times, after such treatment, re-use original charger “adjustment” charge.

 

8. The higher the load is not good, not protecting the circuit fully charged battery must be stopped immediately, otherwise they will have an impact on performance due to fever or overheating. Theoretical calculation of IBM ThinkPad R52 battery charging time is as follows: power battery charger, divided by the output current can be, for example a 800mAh battery, for example, the charger output current 500MA, then the time load is equivalent to 800MAH/500MA = 1.6 hours, of course, this is a theoretical calculation of time is full of power, while the charger shows charging is completed, preferably about half an hour or and should be given to the size of the battery power-up time. Dedicated lithium-ion battery charger must be selected, or they may not reach saturation, the impact on its performance.
