【摘要】 为了实现电动汽车动力电池热管理和车舱制冷，本文基于AMEsim软件搭建了纯电动汽车空调与电池综合热管理系统仿真模型，研究了压缩机转速、电子膨胀阀的开度对综合热管理系统性能的影响。结果表明：当压缩机转速由1 000r/min升至2 800r/min，电池温度下降9.8℃，车舱温度下降至8.8℃；随着电子膨胀阀1开度增大50%，电池温度升高11.5℃，车舱温度下降5℃；当电池的放电电流由40 A升高至65 A时，将压缩机转速由1 250 r/min升至2 700 r/min和电子膨胀阀的开度比从1.20升至3.89，可以使车舱温度保持在23℃，电池温度保持在35℃，从而实现电动汽车综合热管理系统的控制。更多还原

【Abstract】 In order to realize the battery and cabin thermal management of electric vehicles, a model of an integrated thermal management system for electric vehicle air-conditioning and battery is proposed in AMEsim.The effect of compressor rotational speed and the opening of electronic expansion valve on the system performance are studied. The results showed that, the battery and cabin temperature separately decreased by 9.8 ℃ and 8.8 ℃ with the compressor rotational speed increasing from 1 000 r/min to 2 800 r/min. In addition,with the opening of the electronic expansion valve 1 increasing 50%, the battery temperature is increased by 11.5 ℃, while the cabin temperature is decreased by 5 ℃. When the discharge current varies from 40 A to 65 A,the rotational speed simultaneously is increased from 1 250 r/min to 2 700 r/min and the opening ratio of the electric expansion valves is magnified from 1.2 to 3.89, the cabin and battery temperature are kept at 23 ℃ and 35 ℃ respectively.更多还原
