The embodiment of the invention provides a thermal management method and device, a vehicle and a readable storage medium, and the method comprises the steps: obtaining the highest temperature and the lowest temperature of each battery pack based on the current temperature of each battery pack in the vehicle; determining a to-be-executed heat treatment request based on the highest temperature and the lowest temperature; and under the condition that at least two to-be-executed heat treatment requests exist, determining a target heat treatment request from the at least two to-be-executed heat treatment requests based on the highest temperature and the lowest temperature, and responding to the target heat treatment request. Therefore, when the target heat treatment request is determined, a fixed strategy that cooling is greater than heating and greater than uniform temperature is not adopted any more, but different target heat treatment requests are determined according to the current temperature of the battery pack and according to the difference between the highest temperature and the lowest temperature, so that corresponding heat management can be carried out based on the actual use condition of the battery; and the flexibility of thermal management is improved, so that the service life of the battery can be ensured to a certain extent.
本发明实施例提供了一种热管理方法、装置、车辆及可读存储介质,方法通过基于车辆中各电池组的当前温度,获取各电池组中的最高温度和最低温度;基于最高温度和最低温度,确定待执行的热处理请求;在存在至少两个待执行的热处理请求的情况下,基于最高温度和最低温度,从至少两个待执行的热处理请求中确定目标热处理请求并响应目标热处理请求。这样,在确定目标热处理请求时,不再是采取冷却大于加热大于均温的固定策略,而是根据电池组的当前温度来确定,根据最高温度和最低温度的不同,确定不同的目标热处理请求,从而可以基于电池的实际使用状况进行相应的热管理,提高了热管理的灵活性,进而可以一定程度上保证电池的使用寿命。
