Electric drive accelerates China's pure electric vehicles to overcome technical difficulties

Since 2001, China has launched a major technology project for electric vehicles, with fuel cell vehicles, hybrid vehicles and pure electric vehicles as “three verticals”. Multi-energy powertrain control, drive motors and power batteries are “three horizontals”. The development layout of “three vertical and three horizontal”. At present, pure electric vehicle technology has made important progress as the basic technology of three types of electric vehicles. Our reporter will report on the technical progress and industrialization development of pure electric vehicles in two phases. 

“The Beijing Pure Electric Bus Team, led by Beijing Institute of Technology and Beijing Public Transport Group, will provide 50 pure electric buses to the Beijing Olympics Central District (Zero Emission Zone) in 2008.” Talking about pure electric vehicles, Beijing Institute of Technology Lin Cheng, deputy director of the Electric Vehicle Engineering Technology Center, expressed his excitement. He told reporters that with the dual support of national policies and funds, they began to develop pure electric buses from the "Ninth Five-Year Plan" period, and that the pure electric buses developed by them during the "Tenth Five-Year Plan" period have been demonstrated in Beijing. During the Five-Year period, it also undertook the research and development project of the National 863 Program pure electric bus power system technology platform. Now, the pure electric bus they developed has been on the national electric car product announcement, and the battery used has passed the test of the authority designated by the state.

China has always attached great importance to the development of clean and efficient automotive technology. Since 2001, the state has launched the 863 program electric vehicle major project, involving three types of electric vehicles: pure electric electric vehicles, hybrid electric vehicles and fuel cell electric vehicles. Lin Cheng pointed out that pure electric vehicle technology is the basis of other electric vehicle technology. Therefore, solving the technical difficulties of pure electric vehicles is also the key content of developing two other electric vehicles.

Pure electric vehicle advantage highlights

Oil-driven vehicles emit a large amount of atmospheric pollutants such as carbon, nitrogen, sulfur oxides, hydrocarbons, and lead compounds every day. They are important sources of atmospheric pollution and cause serious harm to human health and the ecological environment.

Without the environment, there is no future for the automotive industry. People in the industry agree that energy conservation and emission reduction are the eternal theme of the development of the automotive industry. At the just-concluded National "Two Sessions", NPC deputies and CPPCC members proposed that we must increase the development and promotion of energy-saving and environmentally-friendly vehicles, and introduce more and stronger incentives to support this industry.

Yang Yusheng, an academician of the Chinese Academy of Engineering, believes that among the many technical solutions studied by the state, electric vehicles have become the most competitive technology because of their high efficiency, energy-independent fuel, and zero emissions at the place of use. Compared with the three types of electric vehicles, the advantages of pure electric vehicles are more obvious. Pure electric vehicles use electric motors instead of fuel engines, with low noise and no pollution. The space and weight of electric motors, oil materials and transmission systems can be used to compensate for the demand of batteries. At the same time, due to the use of a single electric energy source, the electronic control system is compared with hybrid electric vehicles. Greatly simplified, it reduces costs and compensates for part of the price of the battery. Moreover, the battery of a pure electric vehicle can be charged at night by using the cheap "valley" of the power grid to stabilize the peak-to-valley difference of the power grid. For the user, using the time-priced cheap "Gudian", as long as the 2-3 yuan electricity bill can save 50 yuan of fuel. In short, pure electric vehicles are of great interest to the country, the power grid, the environment, and the users.
