The invention provides a thermal management system, a control method and device and an automobile, and relates to the technical field of automobiles. The thermal management system comprises a passenger compartment heating loop, a battery heating loop, a motor heat dissipation loop, a first four-way reversing valve connected with the passenger compartment heating loop and the battery heating loop,and a second four-way reversing valve connected with the battery heating loop and the motor heat dissipation loop. The passenger compartment heating loop, the battery heating loop and the motor heat dissipation loop are coupled through the two four-way reversing valves and integrated into a whole; vehicle heat resources are fully utilized by controlling the conduction states of the two four-way reversing valves, supplementation of a whole vehicle heat system by means of electric energy is reduced to the maximum extent, vehicle electric power resources are saved, and endurance mileage is prolonged.
本发明提供了一种热管理系统、控制方法、装置及汽车,涉及汽车技术领域。该热管理系统,包括:乘员舱加热回路、电池加热回路和电机散热回路;第一四通换向阀,与乘员舱加热回路和电池加热回路分别连接;第二四通换向阀,与电池加热回路和电机散热回路分别连接。通过两个四通换向阀将乘员舱加热回路、电池加热回路和电机散热回路进行耦合,将其整合为一个整体,通过控制两个四通换向阀导通状态的控制,实现对车辆热量资源的充分利用,最大限度减少依靠电能对整车热系统进行的补充,节约车辆电力资源,延长续航里程。
