Abstract: Based on the conception of new energy automobile, the procedure of focusing on three different new energy automotive types are described. The promoting effect for the development of new energy automotive industry is analyzed with the technology progress. The development level and the tendency of key technologies for new energy automotive industry, such as battery, motor, electric control system and the chassis are discussed. With the progress of technologies, it is pointed out that the new energy automobile in the near future will be made based on more electric, intelligent, network, lightweight and so on. This will lay the foundation for the full realization of the intelligent transportation system with more safety, energy-saving and driving convenience.
