The invention provides a heat management system of an electric vehicle. The heat management system comprises a first compressor, a second compressor, a first heat exchanger, a heat regenerator, a first electronic expansion valve, a gas-liquid separator, a second electronic expansion valve, an in-vehicle evaporator, a battery cooler, a first water pump, a battery pack water cooling plate, a second water pump and a first radiator. According to the heat management system, the refrigerating loop of the passenger compartment and the cooling loop of the battery can be connected in series to achieve secondary cooling, the connection relation of the heat management system in the refrigerating mode is simplified, and energy consumption is reduced.

    本发明提供了一种电动车辆的热管理系统,包括:第一压缩机、第二压缩机、第一换热器、回热器、第一电子膨胀阀、气液分离器、第二电子膨胀阀、车内蒸发器、电池冷却器、第一水泵、电池包水冷板、第二水泵以及第一散热器。所述热管理系统可将乘员舱制冷和电池包括冷却的回路串联起来实现二次冷却,简化了制冷模式下的热管理系统的连接关系并节省了能耗。
