电动汽车电动机工作参数的优化设计

Optimal Design of Working Parameters of Electric Vehicle Motor

按照国家电动汽车设计标准,对现有的电动汽车驱动系统的功率、转矩、转速等参数配置进行了计算和优化设计,对电动汽车的不同工况进行动力性和经济性分析,在满足车辆安全的条件下,寻求电动汽车电动机工作参数的最优化,选择合适的电机功率以提高电动汽车性能,可供电动汽车设计人员参考。

According to the national design standard of electric vehicles,the power,torque,speed and other parameters of the existing electric vehicle drive system are calculated and optimized,and the power performance and economy of the electric vehicle under different working conditions are analyzed.Under the condition of meeting the vehicle safety,the optimization of the working parameters of the electric vehicle motor is sought,and the appropriate motor power is selected to improve the performance of the electric vehicle.The paper can be used as a reference for electric vehicle designers.
