Based on some types of EVS, the parameters of power train of EVS were selected and designed reasonably. A performance simulation model of dynamic power train system in whole vehicle and key parts, such as electromotor, cells and retarder were developed utilizing the EVS dynamic simulation soft of advanced vehicle simulator (ADVISOR). Then the dynamic performance of EVS was simulated. Simulation result indicates that the dynamic performances of lithium cells EVS, including acceleration performance, grade ability, the maximum speed of the vehicle, retaining distance and etc. are satisfied to the demands of designing guide line. So the correctness and validity of the simulation model are demonstrated.
