Simulation analysis of electric vehicle power system based on cruise

In this paper, the drive motor, main deceleration ratio, tire and power battery of an electric vehicle are matched and calculated, and the parameters of the main components of the powertrain are obtained. In order to improve the authenticity of the vehicle matching design, the vehicle model is built on the AVL CRUISE software, and similar configuration models are selected in the road test database for test verification, so as to prove that the results of the matching calculation meet the design requirements. By modifying the model parameters, the results of relevant test projects can be quickly obtained to meet the design requirements of rapid product iteration, which lays a solid foundation for enterprises to save costs and shorten the research and development cycle.
