The invention discloses a heat management system and a control method thereof, a storage medium, a controller and a vehicle. When the heat management system is in a refrigerant flushing state, an inlet of a liquid storage tank communicates with an exhaust port of a compressor, and an outlet of the liquid storage tank communicates with an air suction port of the compressor; when the thermal management system satisfies a first condition, the thermal management system is in a battery heating state. Therefore, the refrigerant flushing state is set before the battery heating state, when the battery needs to be heated, the heat management system is in the refrigerant flushing state firstly, and a high-temperature and high-pressure refrigerant discharged by the compressor can take out the refrigerant in the liquid storage tank, so that the refrigerant in the liquid storage tank can participate in heat exchange of the heat management system; the quantity of refrigerants participating in circulating heat exchange in the heat management system is effectively increased, and the circulating quantity of the refrigerants participating in heat exchange in the heat management system is large, so that the battery heating efficiency of the heat management system can be effectively improved, the charging and discharging performance of the battery is improved, and the running stability and safety of the compressor are improved.
本发明公开了一种热管理系统及其控制方法、存储介质、控制器和车辆,当热管理系统处于冲冷媒状态时,储液罐的入口与压缩机的排气口连通且储液罐的出口与压缩机的吸气口连通;当热管理系统满足第一条件时,热管理系统处于电池加热状态。由此,通过在电池加热状态前设置冲冷媒状态,在需要对电池进行加热时,热管理系统先处于冲冷媒状态,压缩机排出的高温高压冷媒可以将储液罐中的冷媒带出,使得储液罐中的冷媒可以参与热管理系统的换热,有效增加热管理系统中参与循环换热的冷媒量,热管理系统中参与换热的冷媒循环量多,从而可以有效提高热管理系统对电池加热的效率,提高电池的充放电性能,并且有利于提高压缩机运行的稳定性和安全性。
