电动汽车传动系结构布置及动力性仿真

Structural Layout of Power Train and Simulation of Dynamic Performance for Electric Vehicles

以微型电动客车为研究对象,对电动汽车动力传动系结构布置进行了探讨,分析了可变速比传动和固定速比传动两种形式下电动汽车的加速和爬坡性能。理论分析、仿真研究和实例验证均表明,采用可变速比减速器不仅可以提高电动汽车的加速性能和爬坡能力,还可以加快电动汽车的改造进程,加速电动汽车的产业化步伐。

Based on the electric minibus,the structural layout of power train for electric vehicle (EV) was discussed.Acceleration performance and grade ability of EV were analyzed in the modes of the variable ratio transmission and fixed ratio transmission respectively.The results of theoretical analysis,simulation and example show that variable ratio transmission can improve the acceleration performance and grade ability of EV, and expedite the rebuild and industrialization of EV.
