The invention relates to a vehicle thermal management system, method and device, a controller and a storage medium. In a vehicle, a first port of a first three-way valve communicates with a liquid outlet of a motor, a first liquid inlet of a battery heat exchanger communicates with a third port of the first three-way valve, a first liquid outlet communicates with an inlet of a motor water pump, an outlet of the motor water pump communicates with a liquid inlet of the motor, and the battery heat exchanger and a battery are correspondingly arranged; the controller is communicated with an outlet of the one-way valve and an inlet of the motor water pump, controls the states of the first three-way valve and the one-way valve based on the motor temperature and the cooling liquid temperature, cools the motor and heats the low-temperature battery through the cooling liquid absorbing heat to achieve heat recovery. Compared with a traditional mode that a plurality of independent heat circulation loops are arranged, according to the scheme, the heat management loops of different systems are communicated through the three-way valves, independent control over the heat management loops is achieved, the control strategy of heat management is determined by monitoring the temperature of all components, and the energy utilization rate is increased.
本申请涉及一种车辆热管理系统、方法、装置、控制器和存储介质。通过在车辆中令第一三通阀的第一端口连通电机的出液口,电池换热器的第一入液口连通第一三通阀的第三端口,第一出液口连通电机水泵的入口,电机水泵的出口连通电机的入液口,电池换热器和电池对应设置,连通单向阀的出口和电机水泵的入口,控制器基于电机温度和冷却液温度,控制第一三通阀和单向阀的状态,分别对电机进行冷却以及将吸热后的冷却液的加热低温电池实现热量回收。相较于传统设置多个独立的热量循环回路,本方案通过设置三通阀将不同系统的热管理回路进行连通并实现各热管理回路的独立控制,通过对各个部件的温度进行监控确定热管理的控制策略,提高能量利用率。
