摘　　要：鉴于纯电动汽车与普通汽车的空调系统负荷特性的较大差异,引入电动机室传入热的概念。在考虑电池包对空调冷负荷影响的基础上,对空调冷负荷进行了计算和测试,得到怠速工况和行驶工况下,从不同围护结构的瞬时得热量随时间的变化曲线。最后,比较分析了理论计算与测试的结果,为纯电动汽车空调系统负荷特性的研究提供参考。In view of the big difference between pure electric vehicles and ordinary vehicles in load characteristics of A /C system,a concept of‘incoming heat from motor compartment＇is introduced. With consideration of the effects of battery pack on the cooling load of A /C system,both calculation and test on the cooling load of A /C system are conducted with the time-history curves of instantaneous heat acquired from different enclosure structures obtained in both idling and normal driving conditions. Finally the results of theoretical calculation and test data are compared and analyzed,providing references for further research on the load characteristics of A /C system in pure electric vehicles.
