A battery management method includes: obtaining a current high-voltage inflection point power value of each cell; obtaining a current historical cumulative balance power value of each cell; obtaining a current equivalent self-discharge value of each cell through calculation; obtaining an equivalent self-discharge value at a previous moment of each cell; obtaining a target equivalent self-discharge value of each cell through calculation; determining a maximum target equivalent self-discharge value and a minimum target equivalent self-discharge value; obtaining a maximum equivalent self-discharge rate and a minimum equivalent self-discharge rate through calculation; and when a difference between the maximum equivalent self-discharge rate and the minimum equivalent self-discharge rate is greater than a preset threshold, managing a target cell corresponding to the maximum target equivalent self-discharge value.
