The embodiment of the invention relates to the field of batteries, in particular to a battery heating control method, a battery management system and a computer readable storage medium, an energy revenue table of a battery is obtained, the energy revenue table represents the corresponding relation of the battery temperature, the battery SOC and energy revenue values, and the energy revenue values comprise a first value and a second value; the first value represents that heating has a positive benefit of energy, and the second value represents that heating has a negative benefit of energy; the battery temperature is monitored, if the battery temperature is lower than a first temperature threshold value and the battery is in a discharging state, the battery SOC is obtained, an energy income value is determined based on the battery temperature, the battery SOC and the energy income table, and if the energy income value is a first value, the battery is controlled to supply power to an external heat source. Under the condition of low temperature of the battery, the battery is controlled to supply power to an external heat source for heating during discharging according to the balance of heating energy income, so that the battery performance is improved.
本发明实施例涉及电池领域,尤其涉及一种电池加热控制方法、电池管理系统以及计算机可读存储介质,通过获取所述电池的能量收益表,所述能量收益表表征电池温度、电池SOC与能量收益值的对应关系,所述能量收益值包括第一值和第二值,所述第一值表征加热具有能量的正收益,所述第二值表征加热具有能量的负收益;监测电池温度,若所述电池温度低于第一温度阈值、且所述电池处于放电状态,则获取电池SOC,基于所述电池温度、所述电池SOC和所述能量收益表确定能量收益值,若所述能量收益值为第一值,则控制电池为外部热源供电。在电池低温情况下,根据对加热能量收益的权衡,控制电池在放电时为外部热源供电进行加热,提高电池性能。
