The invention provides a thermal management system of a pure electric vehicle, which comprises an electronic power device cooling subsystem, an air conditioner refrigerating and heating subsystem and a battery pack cooling and heating subsystem. According to the thermal management system of the pure electric vehicle, the battery pack adopts a water cooling mode and is coupled with the air conditioning system through the heat exchange device, heat of the battery pack is brought out of the vehicle through the high COP value of the air conditioning system, the cooling efficiency is improved, and the energy consumption is reduced; the battery pack is heated at a low temperature. The water cooling mode is also adopted and the water type PTC heating mode is utilized. The heating and cooling of the battery pack share a water circulation system, switching between the water type PTC heating mode and the battery pack is achieved through a switching electromagnetic valve, flow resistance is reduced, and arrangement space is saved.

    本发明提供了一种纯电动汽车热管理系统,一种纯电动汽车热管理系统,包括电子功率器件冷却子系统、空调制冷采暖子系统和电池包冷却加热子系统。本发明所述的一种纯电动汽车热管理系统,电池包采用水冷冷却方式,并通过热交换装置与空调系统耦合,通过空调系统的高COP值将电池组的热量带出车外,提升冷却效率,降低能耗;对于电池包在低温下加热,同样也是采用水冷方式,利用水式PTC加热,电池组的加热和冷却共用一套水循环系统,通过一个切换电磁阀实现二者之间的切换,降低了流动阻力节省了布置空间。
