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.

China North Vehicle Research of major projects of the National Institute of 863 electric vehicles Power Battery Testing Center is the primary test vehicle battery power and authority certification for the state the means of control quality to guide the development of the basic battery of tests, but also at home and abroad to carry out the relevant communication window. At present, China’s battery powers the vehicle in the development and production, what problems still exist? Their technical standards? To solve these problems, this reporter recently interviewed Prince, director of the Center for the winter.

 

“China Automotive News” At present, China’s battery powers the vehicle certification and control, how are we going?

 

Prince of winter: Since 2006, the National Directorate of Vehicle Standards announces new energy battery test in effect, the power of the electric vehicle VGP-BPS13B/B battery before testing the ad should be mandatory. Initially, only a very small output of the battery through certification, is currently about 30% of the production of the product has reached a certain standard. China North Vehicle Research Institute Power Battery Testing Center is the primary test vehicle battery power and authority certification, we passed by the State based on a car battery, battery modules and national standards Project 863 large energy batteries and super capacitors testing standards and all sorts of individual cells, modules, battery performance and safety tests and full tests.

 

Development of new energy vehicles for the safety of battery power and life cycle proposed higher requirements, certification and testing, as the battery from the battery company in the industry threshold of new energy, but this does not mean that by sensing the battery can be well applied to electrical car. Because electric vehicles are electric (EV), fuel and electricity and gas, hybrid electric (HEV, PHEV) and the model for many other performance requirements of the battery varies greatly needed features power to the vehicle VGP-BPS10B battery to assess specific pairing.

 

For the power of the battery of safety tests of performance include acupuncture, overloading, excessive discharge, squeeze, drop, high temperature, short circuit test items, etc. 7. Adopted into a single cell basis, we also test the security module will consist of five cells in the module series of battery tests. Due to cost constraints, at present there are very few companies test the safety of the battery. Testing a cost of “battery pack of 100 thousand to 50 million, while the entire group of test vehicles electric bus battery pack often requires the cost of several million dollars, we now have the batteries used in power real safety data of the electric vehicle, and compared with test data there will be some deviations.

 

“China Automotive News” In the testing and certification, you think how the safety performance of batteries power of China? What problems still exist?

 

Prince of winter: On the security side, China’s leading power vehicle overloading of the VGP-BPS10A battery over-discharge problem is not serious, but more problematic is the short-circuit, acupuncture and squeeze. While the battery life for companies looking to invest substantial funding, but most production of the batteries in these three cases is difficult to ensure. Although acupuncture, short circuit, the compression is borderline, but not underestimate the potential danger. In case of spillage, accident, the implementation of the rescue process, the presence of the battery power of these problems often causes secondary damage.

 

This year, the state-led industrial development of new energy, promote the advancement of electric vehicle technology, however, electric vehicles launched around the relatively blinder. Vehicle battery charge and discharge process is very complicated and complex, motor cars and the environment, often found in the wind, frost, rain, snow and other inclement weather, the battery safety, consistency, stability , demanding. Battery companies not only need to have a strong R & D team, but also a large number of trial experiments, to produce a driving force to meet the application requirements. Currently, Chinese companies generally have no experience of producing batteries supply, equipment manufacturing, sensors, connectors, positive and negative material, divide not advanced enough, there will be a great risk production blind.

 

“China Automotive News”: the last two years, China’s VGP-BPS8B battery production vehicle supply and sales, technical level and scale of development in what way?

 

Prince of winter: the use of point of view, China Ni-MH battery that lithium batteries perform better security, but the lithium battery a higher energy density and longevity. Currently, domestic companies producing lithium batteries more, especially lithium iron phosphate faster than any other battery development. There are many dynamic models of electric vehicles, different models of batteries, has raised one of the requirements of different applications.

 

Scale production and marketing standpoint, my car battery power are in the basic R & D, pilot phase, which has yet to reach mass production, it is not widely used in electric vehicles, short term, businesses in the battery pack is unlikely to achieve profitability.

 

“China Automotive News” with the advanced international level, the gap between the battery power of China is reflected in what areas?

 

Prince of Winter: First, the foreign power batteries using automated production methods, while internal essentially manual and semi-automatics are not likely capabilities of mass production, level of accuracy is not high. Degree of commercialization of view, China has the VGP-BPS10A/B battery power can be sold, while foreign sales of pre-existing motive power free. From the product structure, the foreign accent on the overall design and evaluation battery, including battery heat, energy management, standardization of connectors. In China, the focus of battery companies still in the material of the battery. In addition, foreign battery parameters of development, standardization, serialization functionality significantly, while the size of domestic products, the range varied from a heterogeneous disorder.

 

Second, China is relatively backward battery production facilities of electricity, many companies focus on the subject, ignoring the improvements of the manufacturing equipment. At present, China will depend mainly on the production of batteries and equipment imports expensive, which is our development of battery power vehicle is very unfavorable power batteries in mass production It should be equipment for advanced automation, the focus of advanced research.

 

Third, most independent research firms in China and battery development, funding is limited, can not solve the fundamental problems of battery technology is difficult to advance further. Lack of adequate communication between businesses, all want to know the circumstances of other people do not want to talk about their own experiences, there is widespread low-level study of the phenomenon of repetition. We must learn from Japan, to create a dynamic alliance in battery technology to promote technological development common to spend money on the razor’s edge.

With the growing popularity of laptops, notebooks on all aspects of the problems appeared in various media on the largest number of arguments for the proper use of laptop batteries, notebook batteries of certain items that the use of personal experience, while others claim expert advice (which we often do these sales), all sorts of stories, the number argument.

 

The author is also a regular laptop user, but not an expert, but with several years experience in the use of notebooks, the author through a friend recruited dozens of university students using a computer mobile, so they talk about their experiences on the use of cell phones, coupled with her a little more experience, summed up what is available to the

We as a reference, hoping to give everyone a little help.

 

Argument 1: activation of a new VGP-BPS8 battery

 

View 1: Before you buy a new battery inside, there will be more than 3% of electricity, more than the battery inside the power exhausted, to rest, then reuse a load external power. The charging time must exceed 12 hours, three times in order to activate the battery.

 

View 2: No, the battery for 10 hours of rechargeable battery to activate the activity of the normal load, the method of release for activation.

 

Survey Results: The authors studied 24 students from colleges and laptop users, 18 is the second view, and the manner and does not charge the battery for future use can hurt, of course, exclude damage to the natural elements. The author himself is also the case when the normal use of a new battery for up to two hours and a half, now two years, the state of the battery is still good, still can reach more than two hours, so I fear I have been satisfied?

 

the proposed method: I agree with the second view, based on available information indicates that the activation of cell work should be completed at the factory and a plant cell battery with a capacity of some natural wear to avoid damaging the VGP-BPS8A battery. The activation of the battery must be in no case to protect the circuit can be with its own circuit of lithium-circuit protection, the purpose of this part of the circuit is to prevent the battery charge and excessive discharge usually filled after charging the battery when the indicator light off, the battery can be recharged in electricity, and then you plug the power plug to recharge the battery in the face of what? Available from the battery can be seen on the battery status of any charges, another teaches you offer a simple way to be able to determine whether there during the battery charging, battery charge , where the phenomenon has a fever, when the battery is full after one hour (power plug does not fire), you’ll try the battery to see if the battery is still warm, not hot? The result is undoubtedly the cold, because the battery is not charging and discharging state is certainly not the heat. Manufacturers of portable computers in the factory will offer a new battery for more than 10 hours. This sentence may be generated for some users the wrong point of view first, the author of this opinion, should be taken into account that some notebook manufacturers a new user in the battery again when n is not fully capture the skills, just so they can charge directly for 10 hours, which should be the business opportunity.

 

Secondly, the argument two: whether the AC disconnects the VGP-BPS8B battery?

 

View 1: Use an external power supply when the battery removed.

 

View 2: Use an external power supply is not necessary to remove the battery.

 

Survey Results: Most students in the use of an external power source, the battery removed, only a few use an external power supply when the battery is placed above, the few brands are used by students in several global brands.

 

the proposed method: In fact, if the battery is removed, the conflict has focused on the use of an external power supply when the battery is in charge of question

. We must know that the number of loading and unloading of the battery life is directly related to the lithium-General established the number of loading and unloading are fixed number of charge cycles only 400-600 times, especially products modified, but 800 times, once for each rechargeable batteries a step toward retirement. The first argument is simply because they are afraid to use power, the battery will be conducted on the above charge, not only to increase the number of charge cycles, but also cause an overload. The second view is that the battery is full power on the computer using an external power supply will not recharge. In fact, both views have their right side, but also in the wrong place. Because only the views expressed by individuals is not very full after my investigation, many laptop manufacturers taking into account the vulnerability of the stack, and the proceeds added to technology protection VGP-BPS9 battery, and therefore different laptop batteries corresponding brand protection technology pricing is different, as some large companies are doing very well in this area, such as IBM, Hewlett-Packard, Toshiba, Compaq, etc.. One of the most thoughtful consideration is that IBM, the IBM laptop can detect the location of the discharge of the battery, laptop battery ThinkPad only less than 95% of the time will reload automatically. This can play a very good protective effect on the battery, held today and many other manufacturers followed. So, as drums, you do not have time to use pull down, because only when the capacity is less than 95% of the time, he is responsible. But even so, if you are prolonged use of computers, or will be removed from the battery to compare well, because the long duration of heat generated when the laptop battery will cause some damage. However, some other “little brand” batteries, may not benefit from such treatment because he was not within the protection technology of the battery. I like to use a certain brand of computers phones if the battery is fully charged to the above, when you use an external power supply has been confirmed at the first charge on electricity, because the storage battery, will wear, can not reach 100 %, while not 100% as long as the power supply connected to the load. Each access to an external power supply is equivalent to recharge the battery once, although only a small charge will be yet. It therefore proposes that we use when the machine according to their own situation, look at the manual laptop, choose whether you want to use an external power supply when the VGP-BPS9A battery removed.

 

Thirdly, the argument 3: how to load correctly?

 

View 1: The battery should always be all exhausted, so that consumption of portable computers to automatically stop and reload every time must be filled.

 

View 2: When the battery is very deliberately not pay attention and use it when I wanted to pay extra.

 

Survey Results: The majority of students said that, needless to the view first, as used in automatic standby mode, then load, but also as the second point of view, it is free. Are generally used when the battery must be recharged when the computer has prompted further charge, of course, calls per hour may be set, the default is 3%.

 

the proposed method: In this paper, the proposed method with the majority of students is the same. In fact, regardless of nickel batteries using a laptop-metal hydride, lithium batteries are such a memory effect, and nickel-hydride batteries with metal memory effect is very obvious, but it will effect memory lithium, but his memory effect smaller than nickel-metal hydride Bale. There is no memory effect on lithium-that only exaggerated and irresponsible to do business in advertising, is totally misleading. Well, since the VGP-BPS9A/B battery has a memory effect, it should be noted at the load point, as far as possible, then run out of charge, but you do not need to say deliberately use the computer to s ’stop automatically, so that although there is no harm in using them (because the laptop battery has a charge-discharge secure a laptop automatically shut down has not yet reached the standard battery protection discharge), but you do not feel tired? In fact, less than 3% of the burden in this way is very good, memories will certainly effect compared to natural wear, there should be nothing. The second count on the charge to view the author is totally disagree and we have already said, if the laptop battery nickel metal hydride, lithium, which has a memory effect, if in this way, then the battery life will be shortened.
