The invention relates to a heating system for improving cold region adaptability of a pure electric vehicle. The system comprises an expansion water tank B, an electric water pump B, an electronic two-way valve and a plate heat exchanger A. The electronic two-way valve is connected in series with a first channel of the plate heat exchanger A and then is connected in parallel with a warm air core body in a main heating loop; the expansion water tank B, the electric water pump B, a power battery and the second channel of the plate heat exchanger A are sequentially connected to form a power battery heating loop. The power battery can be heated at a low temperature while a passenger compartment is heated, so that a longer endurance mileage can be ensured, meanwhile, thermal shock to the powerbattery can be prevented, and the reliability of the power battery is improved.

    本发明涉及一种提高纯电动汽车寒区适应性的加热系统,该系统包括B膨胀水箱,B电动水泵,电子二通阀,A板式换热器;所述的电子二通阀与A板式换热器的第一通道串接后与暖风芯体并行连接在主加热回路中;B膨胀水箱、B电动水泵、动力电池与A板式换热器的第二通道顺序连接构成动力电池加热回路。本发明在乘员舱采暖的同时能够对动力电池进行低温加热,因而能够保证更长续航里程,同时能够防止对动力电池的热冲击,提高了动力电池可靠性。
