The invention discloses a new energy electric vehicle multi-working-condition whole vehicle thermal management system and method, and the system comprises a refrigerant circulation loop and a cooling liquid circulation loop, and the refrigerant circulation loop and the cooling liquid circulation loop carry out heat exchange through a water cooling condenser (11) and a battery cooler (14); heat exchange management of each loop of the motor (18), the battery pack (15) and the passenger compartment is carried out through the kettle (17), and then the heat is distributed to each loop for use; and multiple working modes including a refrigeration mode, a heating mode, a series/parallel dehumidification and defrosting mode, a battery fast charging cooling mode, a battery heating mode, a low-temperature compressor self-heating mode, a waste heat recycling mode and the like are achieved. The system is wide in applicable working condition range, high in adaptability, complete in function and capable of being used in cooperation with different refrigerant system structures. The system heating operation temperature can be lowered, the power consumption of the whole vehicle can be reduced, consumption can be reduced, energy can be saved, the energy utilization rate is increased, and the heat management requirements of the passenger compartment and the battery pack under different working conditions can be met.

    新能源电动汽车多工况整车热管理系统及方法,包括制冷剂循环回路和冷却液循环回路,制冷剂循环回路和冷却液循环回路通过水冷冷凝器(11)和电池冷却器(14)进行热交换;通过水壶(17)进行电机(18)、电池组(15)、乘员舱各回路的热量交换管理,然后再分配给各个回路利用;实现涵盖制冷模式、制热模式、串联/并联除湿除霜模式、电池快充冷却模式、电池加热模式、低温压缩机自加热模式以及余热回收利用模式等多种工作模式。适用工况范围广,适配性强,功能齐全,可与不同冷媒系统架构搭配使用。可下探系统制热运行温度,减少整车功耗,可减耗节能,提高能源利用率,可满足在不同工况下的乘客舱与电池组热管理需求。
