摘要：提出纯电动汽车整车热管理夏季方案，电池与乘客舱用制冷剂回路并联冷却，其中电池由制冷剂分支通过热管来冷却，电机采用液冷。在联邦测试-72工况下用系统模拟的方法进行测试。乘客舱温度经过57s，从35℃降到设定温度24℃，随后保持动态平衡；电池温度在68s左右达到设定温度25℃，然后维持设定温度以下；电机温度在前期迅速升高，最高为 61℃，随后冷却液与外界换热增强，温度最终下降至52℃，未超出电机热管理目标80℃。

Battery and the cabin are parallel cooled by refrigerant, and the battery is cooled by the branch of refrigerant through heat pipes, and the liquid cooling system for motor. The thermal management systems is tested by system simulation under the Federal Test Procedure 72. The results show that the temperature of cabin reaches 24 °C at 57 s, and then keeps a dynamic stability. In addition, the temperature of the battery reaches 25 °C at 68 s, and later it is controlled to maintenance the temperature stabilization. The increase of the motor temperature is at a high rate before 400 s, and the highest temperature is 61 °C. When the heat transfer is enhanced, motor temperature is decrease to 52 °C. Finally, the temperature of motor is within 80 °C under the Federal Test Procedure 72.
