Abstract: Aiming at the design of the power train of electric vehicle， the power train selection， motor parameters and transmission parameters of the pure electric vehicle were researched， the advantages of the motor transmission power train compared to the motor reducer power train were analyzed from the points of economy， power and manufacturing cost. In the process of designing power train parameters， the design theory of power train of electric vehicle was put forward from the angles of power， economy， comfort and power train size. The model was established by Matlab and the parameters was simulated by the model. The experiment results indicate that the power train designed meets the requirements of performance targets.
