Abstract: Aiming at the need of pure electric vehicle research and development, the necessity of bench test was introduced. After the analysis of the current electric automobile comprehensive performance test bench of the research status at home and abroad, the pure electric automobile comprehensive performance testbed was established by frame, road simulator, loading device, inertia simulation device, etc.. Combined with the practical requirements of electric vehicle test, it was presented that the electric wheel bench test is important to the development of electric vehicles. A number of improved design scheme of electric wheel comprehensive performance test rig was introduced. The results show that it can truly simulate the car working conditions, but also has the motor test, vertical load test, mechanical and electrical coupling brake test, lateral force test and so many kinds of expanding function, which has great practical effect for studying the performance of pure electric vehicles driven by the wheel motor.

Key words: electric vehicles(EV); drive motor; comprehensive performance test; test bench
