The invention relates to an efficient heat management system for a pure electric vehicle, which comprises a motor heat exchange loop, a battery heat exchange loop and a PTC (Positive Temperature Coefficient) heating loop, simultaneous or independent heating and variable-flow heating requests are realized through the controllable opening degree of an electronic three-way valve, and water replenishing and air exchange functions of a motor heat exchange system and heat exchange of a battery system are realized. A radiator cooling mode is adopted, the energy consumption of the whole vehicle in a low-temperature environment can be saved, and the endurance mileage is increased; the aim of heating the battery and improving the discharge capacity of the battery is achieved by repeatedly utilizing the heat of the motor, the energy consumption of PTC heating can be saved on the premise of avoiding energy consumption waste, the energy consumption of the whole vehicle is reduced, and the diversified requirements of users are met.

    本发明涉及一种纯电动汽车高效热管理系统,包括:电机换热回路、电池换热回路、PTC加热回路,通过电子三通阀的可控开度实现同时或独立加热,以及可变流量的加热请求,实现了电机换热系统的补水、换气功能、电池系统换热,采用散热器冷却方式,能节省低温环境下整车能耗,提升续航里程;通过重复利用电机热量达到加热电池提升电池放电量的目标,避免能耗浪费的前提下还能节省PTC加热的能耗,降低整车能耗,满足了用户的多元化需求。
