The problem of energy saving and environment protection has become more and more crucial in China. China's energy development process shows that the development of pure electric vehicle to China's energy structure optimization and the construction of the ecological environment. New promising technology that makes the problem solved is reviewed in this paper, including current status of electric automobiles, electric vehicle charging systems and future development. It is given the group of customers and charging mode of electric automobiles in China. It is suggested the matches between charging modes and vehicle types. In the short term, conventional gasoline or diesel vehicles is the most realistic and effective, while in the long run, China will meet the urgent challenges of energy crisis and greenhouse gas reduction. It needs technology breakthroughs in battery, public awareness and government input to the development of electric automobiles.
