The invention relates to the technical field of heat management, and discloses a vehicle heat management control method, device and equipment and a storage medium, and the method comprises the steps: determining a corresponding heat demand according to the current environment temperature and the current temperature of a battery pack; generating an engine control strategy according to the heat demand, the current state of the air conditioner and the engine water temperature; controlling an interface of a control valve and the rotating speed of a water pump according to the engine control strategy, the water temperature of the engine and the water temperature of an inverter; after control is completed, a refrigerant expansion valve is adjusted according to the current temperature of the battery, so that control over heat management of the target vehicle is achieved; by means of the mode, whether the engine needs to be forcibly started to generate heat or not is determined according to the current environment temperature and the current temperature of the battery pack, then the connector of the control valve and the rotating speed of the water pump are controlled according to the determination result, then the refrigerant expansion valve continues to be adjusted, and reasonable conversion and utilization of the heat can be achieved; therefore, waste of heat is avoided.

    本发明涉及热管理技术领域,公开了一种车辆热管理的控制方法、装置、设备及存储介质,所述方法包括:根据当前环境温度和电池包的当前温度确定对应的热量需求;根据热量需求、空调的当前状态以及发动机水温生成发动机控制策略;根据所述发动机控制策略、发动机水温以及逆变器水温对控制阀的接口和水泵的转速进行控制;在控制完成后,根据电池的当前温度对冷媒膨胀阀进行调整,以实现对目标车辆热管理的控制;通过上述方式,根据当前环境温度和电池包的当前温度确定是否需要强制启动发动机产生热量,再根据确定结果对控制阀的接口和水泵的转速进行控制,然后继续对冷媒膨胀阀进行调整,能够实现对热量的合理转换和利用,从而避免热量的浪费。
