摘　　要：准确计算空调的冷热负荷是合理设计电动汽车空调系统的关键。夏/冬季炎热/寒冷时期,汽车停用期间车内温度高/低,导致车内空调运行初始负荷大,计算这一阶段的动态负荷是汽车空调负荷评估的关键。为此分析电动汽车空调动态负荷的3种计算方法,以在不同环境温度下运行的电动汽车为实例进行负荷计算,比较不同方法下的夏/冬季动态负荷及温降/升阶段的平均负荷,确定合适的方法,使计算值更接近实际值以满足设计要求。Accurately calculating the heating and cooling loads in winter and summer is crucial for designing electric vehicle air conditioning systems.During hot/cold periods in summer and winter,when the vehicle was park,the interior temperature could rise/fall significantly,resulting in a high initial load on the vehicle′s air conditioning system.Calculating the dynamic load during this stage was key to evaluating the air conditioning load in vehicles.Three calculation methods for the dynamic load of electric vehicle air conditioning systems was analyed,and the load calculation method was givenby taking the operation of electric vehicles at different ambient temperatures as an examples.It compared the dynamic loads and average loads during temperature rise/fall stages using different methods.By compared,an appropriate method was determined to ensure that the calculated values were closer to the actual values,meeting the design requirements.
