The invention discloses a heat pump system of an electric automobile and an electric automobile. The heat pump system comprises a compressor, a gas-liquid separator, a four-way reversing valve, an evaporator, an external heat exchanger, a high-pressure heater, an air conditioner core and a first heat exchanger. A first circulating pipeline is connected among the compressor, the gas-liquid separator, the evaporator and the four-way reversing valve; the external heat exchanger is connected to the first circulating pipeline; the first heat exchanger is connected to the first circulating pipeline;and a second circulating pipeline is communicated between the high-pressure heater and the air conditioner core body and is connected with the first heat exchanger. According to the heat pump systemand the electric automobile, recycled heat can be adopted for heating the air conditioner core body and the battery pack, multiple heating modes can be achieved, different requirements are met, energyconsumption in the system is reduced, attenuation of the endurance mileage of the electric automobile in winter is reduced, and the endurance capacity of the electric automobile is improved.

    本发明公开了一种电动汽车热泵系统及电动汽车,包括压缩机、气液分离器、四通换向阀、蒸发器、外部换热器、高压加热器、空调芯体和第一换热器;所述压缩机、所述气液分离器、所述蒸发器和所述四通换向阀之间连接有第一循环管道;所述外部换热器连接在所述第一循环管道上;所述第一换热器连接在所述第一循环管道上;所述高压加热器与所述空调芯体之间连通有第二循环管道,所述第二循环管道与所述第一换热器连接。本发明公开的电动汽车热泵系统及电动汽车,可以采用回收的热量给空调芯体采暖和电池包加热,可以实现多种加热模式,满足了不同的需求,减少了系统中能量的消耗,减小了电动汽车在冬季续航里程的衰减,提高了电动汽车的续航能力。
