空调系统作为电动汽车上能耗最大的辅助设备，其能耗对整车能效有很大的影响。建立了电动汽车空调系统年总能耗的综合评价模型。基于车内热舒适性和气候控制负荷方法，考虑了气候数据、车辆使用强度、平均行驶速度和空调系统性能等主要影响因素。利用该模型对我国30个省会城市轻型汽车空调系统的能耗进行了分析。给出了采暖能耗与纬度的拟合曲线。结果表明，不同城市的空调系统能耗差异较大，热泵系统平均节能41.03%。
As the largest energy consumption auxiliary device on the electric vehicle, the energy consumption of air conditioning system has a great impact on total energy efficiency. A comprehensive model is established in this article to evaluate the total annual energy consumption of electric vehicle air conditioning system in different cities across China. The major influencing factors, such as climate data, vehicle-use intensity, average driving speed and the performance of air conditioning system are taken into consideration based on a cabin thermal comfort and climate control load approach. With the model, the energy consumption of air conditioning system in light duty vehicles is analyzed in 30 province capital cities across China. The fit curves of heating energy consumption to latitude are also given. It is found that the energy consumption of air conditioning system varies largely in different cities, and the heat pump is capable of saving 41.03% heating energy in average.
