摘　　要：电动汽车冬季采暖热负荷计算是热泵型电动汽车空调热力计算的首要步骤和系统设计的主要依据。电动汽车空调系统与普通的汽车空调相比,动力源不同,热负荷特性有很大差异。为此,在延续和完善夏季冷负荷特性试验研究思路与方法的基础上,利用一台国产电动汽车进行多工况下的整车试验,得到车体各部分的热负荷变化曲线,并结合理论计算进行比较分析。通过对比车底和车顶的热负荷特性,探究车底电池包对热负荷的影响,以期对电动汽车空调系统的研发提供更全面的参考。The first step of thermodynamic calculation on the heat pump air-conditioning system of electric vehicle in winter heating is to achieve the heating load,which is also the primary basis of system design.The air-conditioning system of electric vehicle is greatly different from that of traditional engine-driven vehicle in heating load characteristics because of their different power supply modes.Based on the improvement of the summer cooling load experiment method,the air-conditioning system of one domestic electric vehicle is measured in various heating operation conditions.Based on traditional theory calculation method,the variation curve of heating load in every part of the vehicle are compared and analyzed.Through comparing the heating load characteristics of vehicle bottom and roof,the influence of vehicle battery package on the heating load is also analyzed.The results aim at providing a more comprehensive reference for the design and development of the air-conditioning system for electric vehicle.
