The embodiment of the invention provides a battery state correction method and device, a storage medium and a battery management system. The method comprises the following steps: in response to an obtained vehicle power-on signal, determining power-on effective time; calculating interval time according to the power-on effective time and the stored previous power-on effective time; determining a capacity loss value according to the interval time; and correcting the battery state according to the capacity loss value. In the technical scheme provided by the embodiment of the invention, the self-discharge working condition of the battery can be identified, the correction accuracy of the battery state is improved, the accuracy of the battery electric quantity is improved, and the battery life is prolonged.

    本发明实施例提供了电池状态的修正方法、装置、存储介质和电池管理系统。该方法包括:响应于获取的整车上电信号,确定出上电有效时间;根据上电有效时间和存储的上一个上电有效时间计算出间隔时间;根据间隔时间确定出容量损失值;根据容量损失值对电池状态进行修正。本发明实施例提供的技术方案中,能够识别电池的自放电工况,提高电池状态的修正准确性,进而提高电池电量的准确性,提高电池寿命。
