The electric vehicle power system parameters have an important impact on the vehicle performance.Based on the dynamic performance simulation analysis,CarSim and Simulink are selected to establish a joint simulation model.The influence of the key parameters of the electric vehicle on the dynamics is analyzed,including the centroid position and the moment of inertia.The selection method of the relevant parameters,as well as the joint simulation interface setting are introduced.Through simulation conditions of constant speed cruising,full acceleration and climbing test,the accuracy of the model simulation is verified.The results show that the model has certain simulation accuracy and can be used as a power simulation platform for electric vehicles.
