Abstract: Electric vehicles is a complex multi-domain coupled physical system. Based on the multi-domain unified modeling language modelica, models’parameters of various system can achieve a seamless solution and optimization. In the electric vehicle performance simulation analysis, electric vehicle motor drive system is the core components and its accuracy and usefulness occupy a very important position. In this paper, Modelica language was used, based on Dymola platform, permanent magnet synchronous motor drive system simulation model was builted and in combination with motor and drive system test bench experiment, the motor drive system was inspected and corrected. On this basis, the motor drive system model was tested with an experimental pure electric vehicle simulation, simulation results close to the results of test bench, and the correctness and feasibility of this article were verified.
