The invention discloses a thermal management method, a thermal management system, a storage medium and a vehicle. The thermal management method comprises the following steps: S1, setting a sampling time period r; s2, acquiring temperature data, voltage data and current data of the battery in the sampling time period r; s3, obtaining a battery state comprehensive value FG according to the temperature data, the voltage data and the current data of the battery in the sampling time period r; and S4, comparing the FG with a set battery state threshold value E, if the FG is greater than E, judging that the battery is in an abnormal state, controlling the thermal management system to enter a battery heat exchange amount adjusting state, and if the FG is less than or equal to E, maintaining the working state of the thermal management system. According to the thermal management method provided by the invention, the state of the battery is judged through the temperature data, the voltage data and the current data of the battery, so that the accuracy degree of judging the state of the battery by the thermal management system can be improved, the adaptation degree of a heat exchange strategy of the thermal management system and the working state of the battery is improved, and the safety of the battery is improved.

    本发明公开了一种热管理方法、热管理系统、储存介质和车辆,热管理方法包括:S1、设置取样时间段r;S2、获取取样时间段r内的电池的温度数据、电压数据和电流数据;S3、根据取样时间段r内的电池的温度数据、电压数据和电流数据获得电池状态综合值FG;S4、对比FG和设定电池状态阈值E,若FG>E,则判定电池处于异常状态,控制热管理系统进入电池换热量调整状态,若FG≤E,则维持热管理系统工作状态。根据本发明的热管理方法,通过电池的温度数据、电压数据和电流数据对电池的状态进行判定,可以提高热管理系统对电池状态判定的精准程度,从而提高热管理系统的换热策略与电池的工作状态的适配程度,提高电池的安全性。
