The invention relates to the technical field of hybrid vehicles, and particularly discloses a battery thermal management system of a hybrid vehicle. The system comprises a refrigerant circulation loop, a battery pack natural cooling loop, a battery pack forced cooling loop, a battery pack direct heating loop and a battery pack indirect heating loop; the working states of a plurality of three-way electronic water valves, an electronic water pump, an electric compressor, an electromagnetic expansion valve and other components are controlled through a controller, and the heating and cooling requirements of a battery pack are met. Therefore, the battery pack natural cooling loop, the battery pack forced cooler loop, the battery pack direct heating loop and the battery pack indirect heating loop are switched and matched, so the problem that the battery pack is overheated and overcooled can be effectively, quickly and energy-saving solved, the battery pack can normally work under any workingcondition, and a hybrid vehicle can obtain the environmental adaptability comparable to that of a traditional fuel vehicle.

    本发明涉及混动车辆技术领域,具体公开了一种混动汽车电池热管理系统。它包括冷媒循环回路、电池包自然冷却回路、电池包强制冷却回路、电池包直接加热回路和电池包间接加热回路,通过控制器控制多个三通电子水阀、电子水泵、电动压缩机、电磁膨胀阀等部件的工作状态,实现电池包的加热及降温需求。由此,通过电池包自然冷却回路、电池包强制冷器回路、电池包直接加热回路、电池包间接加热回路间的切换配合,能够有效快速、节能的解决电池包过热和过冷的问题,从而保证电池包在任何工况下都能正常工作,并使混动车辆得到与传统燃油车媲美的环境适应能力。
