采用交流感应电机的电动汽车动力传动系统的合理匹配

Study on Power-Train Matching of Electric Vehicle with AC Induction Motor

研究了交流感应电机的输出特性与汽车行驶特性的匹配，电机、电池容量的选择，并采用优化方法确定传动系速比，使整车具有较好的动力性指标和经济性指标。

This paper focuses on the matching of electric vheicle power-train with AC motor. The results show that constant power characteristics of AC output is suitable for electric vehicle. It also shows that the optimal ratio of drive train satisfies the performance and economy requirements of electric vehicle and makes vehicle acquire better criteria of tractive performance and fuel economy.
