摘　　要：基于车辆运行城市道路工况,结合车辆设计指标,以降低车辆能耗为目标,进行了动力驱动系统中电池、电动机及传动系统参数的优化匹配.对济南市道路工况进行测试,分析得到车辆行驶工况点密集区域.综合车辆设计目标,电池组电压及电池组质量对车辆能耗的影响,进行动力驱动系统关键部件选型,并在试验台上对选择的7.5 kW交流异步电动机系统效率特性、192 V/100 A.h磷酸铁锂电池组效率特性及其之间的匹配特性进行测试分析.利用底盘测功机测试并优化了电力驱动系统与机械传动系统之间的匹配关系,使电力驱动系统高效区与车辆实际道路行驶工况点密集区域相吻合.等速法测试结果表明:车辆按40 km·h-1匀速行驶里程达169 km;车辆在基本城市循环工况下100 km能耗为12·01 kW·h,续驶里程达160 km.To lower EV energy consumption, the optimal matching of battery pack, driving motor and transmission system parameters of power-train was carried out based on car design index and city road conditions. The driving cycle of Jinan city was tested with pure electric microbus to contour the ordinary EV running conditions. A 7.5 kW AC asynchronous motor and a 192 V/100 A·h LiFePO4/C battery pack for the power-train were analyzed by consideration of car design index, battery pack voltage and mass effect on energy consumption. The efficiency characteristics of the driving motor, the battery pack, the matching character were determined by the EV test bench. The matching relationship between the electrical power driving system and the mechanical transmission system was measured by chassis dynamometer and optimized to suit for most EV common driving conditions. The results show that the EV endurance mileage reaches 169 km under 40 km · h-1 by constant speed metering method. Under the basic urban driving cycle, the endurance mileage reaches 160 km with energy consumption of 12.01 kW ·h/100 km.
