China's key components in electric vehicle motor technology have made major progress, but in the product integration, reliability, and system application technology, but with the international advanced level there is a big gap, is mainly reflected in these few areas: China a reliable assessment Sex and the issuance of life is not clear, assessment work has not done enough in place; motor, controller, DC / DC volume,quality is generally too large; adaptive research assessment on the environment there are also inadequate; modular design inadequate,insert Then pieces of the standard there is no effective unified,engineering degree to be improved; the key power electronics components are imported not only the ability to self-produced.

    Electric cars motor difficulties in the industrialization as following :Electrical contact with the vehicle very close thing, the basic need to be synchronized and vehicle development, it is difficult large-scale standardized production, only in accordance with specific plans for the various models and production. Motor is difficult, as the battery as a standardized product made, the first step can hope to achieve standardization of interface areas.
