为比较纯电动汽车不同驱动系统的关键性能，基于同一整车参数和某公司提供的可变绕组永磁同步电机试验数据，对纯电动汽车电机驱动系统开展了相关研究。基于精英保留遗传算法和动态规划理论，对单挡、两挡电控机械式自动变速器驱动系统的速比进行了设计优化。采用了精英保留遗传算法和动态规划理论对系统速比进行设计优化，并对可变绕组永磁同步电机绕组切换过程进行了动力性和经济性设计。仿真结果表明，在动力性上，两挡自动变速器驱动系统的加速性能最优;在经济性上，可变绕组永磁同步电机驱动系统的百公里能耗最小，单挡自动变速器驱动系统的动力性和经济性表现最不理想。
Comparative Study on Key Performance of Battery Electric Vehicles Under Different Drive Systems
To compare the key performance of different drive systems in battery electric vehicles,a study on the motor drive system was carried out based on the same vehicle parameters and company-provided experimental data for variable-winding permanent magnet synchronous motors.Using the elite-preserving genetic algorithm and dynamic programming theory,the speed ratios for both single-and two-speed AMT drive systems were designed and optimized.These methods were applied to optimize the system speed ratios,and to design the dynamic and economic aspects of the winding switching process in variable-winding permanent magnet synchronous motors.The simulation results show that in terms of dynamics,the two-speed AMT drive system offers the best acceleration performance.In terms of economy,the variable-winding permanent magnet synchronous motor drive system achieves the lowest energy consumption per 100 km.Conversely,the single-speed drive system exhibits the least satisfactory performance in both dynamics and economy.
