Energy issue of pure electric vehicle in China

pure electric vehicle•promotion can not only mitigate the recent traditional vehicle contradiction between supply and demand of energy, solve the vehicle energy problem after the exhaustion of fossil fuel, but also improve environment quality and energy utilization efficiency.But PEV promotion is restricted by infrastructures such as energy, power supply, charging station and so on. •According to the composition characteristics of Chinese primary energy, situation of Chinese power industry and requirement of power infrastructures of pure electric vehicle, I analyzed the shortcomings in the power industry while PEV are promoted in China. There are four major problems in PEV promotion. First, in China more than 70% power supply is from coal, and the average coal consumption of power generation is high. Second, electricity generation per person-year of China is far less than that of developed countries, and power shortage exists in some areas. Third, the stability of power supply is poor because it can be easily affected by some uncertain factors, such as the supply of water, coal and natural gas. Furthermore, current power capacity can not meet the requirements of the PEV promotion. In order to promote PEV, power industry must acquire high power efficiency, sufficient power supply, and extensive use of clean fuel or renewable energy etc.
