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.
