Abstract: The parameter matching of power system is one of the core technologies of electric vehicle. In this paper, linear acceleration racing car as the research object, in order to optimize the dynamic performance index of the car as the goal, linear acceleration racing car power system parameters matching and the selection of the main components. In ADVISOR, the acceleration time, maximum speed and motor working state are analyzed, and the transmission speed ratio of linear accelerated racing car is optimized according to the simulation results.The simulation results show that the overall performance of the car and the working characteristics of each component are well reflected, and its dynamic performance basically reaches the preset value, indicating that all parameters are in a reasonable range.
