一种电动汽车热管理系统、热管理方法及电动汽车,其中,热管理系统包括电池热循环回路、空调热循环回路、以及能够储存热量的储热罐,储热罐分别与电池热循环回路及空调热循环回路热耦合;电动汽车冬季工况下,在充电阶段,储热罐储存动力电池充电过程中所散发的废热;在启动阶段,储热罐为电池热循环回路供热同时将储热罐为空调热循环回路供热;在稳定运行阶段,储热罐储存动力电池放电过程中散发的废热,同时将储存的热供给空调热循环回路,实现整车的热管理。本发明能够有效解决电动汽车冬季工况下、启动阶段无法同时满足动力电池组加热与客舱供暖需求的问题,且热管理调控集中、热能利用率高。
The invention discloses an electric vehicle thermal management system and method and an electric vehicle, the thermal management system comprises a battery thermal circulation loop, an air conditioner thermal circulation loop and a heat storage tank capable of storing heat, and the heat storage tank is thermally coupled with the battery thermal circulation loop and the air conditioner thermal circulation loop; under the working condition of the electric vehicle in winter, in the charging stage, the heat storage tank stores waste heat dissipated in the charging process of the power battery; in the starting stage, the heat storage tank supplies heat to the battery heat circulation loop and supplies heat to the air conditioner heat circulation loop at the same time. In the stable operation stage, the heat storage tank stores waste heat emitted in the discharging process of the power battery and supplies the stored heat to an air conditioner heat circulation loop at the same time, and heat management of the whole vehicle is achieved. The system can effectively solve the problem that the electric vehicle cannot meet the requirements of power battery pack heating and passenger cabin heating at the starting stage at the same time under the working condition in winter, and is centralized in heat management regulation and high in heat energy utilization rate.
