Based on analysis of coupling relationship among acceleration ability, climbing ability, maximum speed, transmission gears and driving motor parameters, key power components parameters matching and selec-tion of Extended-range Electric Vehicles (e-revs) drive system is carried out. Finally e-revs vehicle simulation model is established with Matlab/simulink to simulate and verify the dynamic and economy performance under electric mode. The dynamic performance of the 0-50km/h acceleration time was 4.24 seconds, overtaking 50-80km/h acceleration time is 7.16 seconds, pure electric mode mileage is about 83.86km, the vehicle energy consumption per hundred kilometers is about 14.516kwh. The results show that key power components meet the dynamic performance and economy matching requirement.%基于加速能力、爬坡能力、最高车速和变速器挡位数、驱动电机参数之间的耦合关系分析,开展增程式电动汽车驱动系统关键动力部件的参数匹配及选型确定.采用Matlab/simulink建立增程式电动汽车整车仿真模型,对纯电动模式下的动力性和经济性进行仿真验证,动力性表现为0~50km/h加速时间为4.24秒,50~80km/h超车加速时间为7.16秒,纯电动状态下行驶里程约为83.86km,车辆百公里能耗约为14.516kwh,表明所确定的关键动力部件满足动力性及经济性的匹配要求.
