Abstract: This study utilizes the Simulink simulation tool to conduct an in-depth investigation into the modeling methods for battery electric vehicles. By designing specific simulation working conditions, the dynamic performance and energy economy of the vehicle are validated, providing an experimental basis for performance optimization. Firstly, taking a specific battery electric passenger car as a prototype, the principles and methods of editing script files and performing modular modeling in Simulink are elaborated. Secondly, the various subsystem modules are organically integrated to construct a complete battery electric vehicle model. Subsequently, parameters related to the vehicle's dynamic performance and energy economy are obtained through simulation runs under the new European driving cycle (NEDC), acceleration, and hill-climbing conditions. Finally, a comparative analysis of the simulation results is conducted, offering theoretical support and data for the design optimization, parameter adjustment, and performance enhancement of battery electric vehicles. The accuracy and effectiveness of the established vehicle model are verified, laying a solid foundation for subsequent research.
