A passenger compartment warm air heat loop and a battery heat loop share only one electric heating source, and heat is provided for the passenger compartment warm air heat loop and/or the battery heat loop by switching the flow direction of the electric heating source, so that the passenger compartment warm air heat loop and the battery heat loop are supplied at different temperatures. In addition, heat of the electric heating source can be extracted through the refrigerant loop and supplied to the passenger compartment warm air heat loop, and therefore the requirements for refrigerating and heating of the system are met while energy consumption is reduced. According to the invention, while the production cost is reduced, the thermal management energy consumption of the whole vehicle is reduced, and the thermal management efficiency of the whole vehicle is improved.
本发明公开了一种新能源车整车热管理系统,其乘客舱暖风热回路和电池热回路共用仅有的一个电加热源,通过切换电加热源流向为乘客舱暖风热回路和/或电池热回路提供热量,使乘客舱暖风热回路和电池热回路不同的温度供给。本发明还能利用制冷剂回路抽取电加热源的热量供给至乘客舱暖风热回路,从而在降低能耗的同时实现系统制冷与制热的需求。本发明能在降低生产成本的同时,降低整车热管理能耗,提高整车热管理效率。
