Battery control method and device, computer equipment and storage medium

The invention relates to a battery control method and device, computer equipment, a storage medium and a computer program product, firstly, a battery is charged at a preset initial charging rate until the voltage of the battery reaches an initial charging cut-off voltage, and then the battery is charged at a preset buffer charging rate smaller than the preset initial charging rate until the voltage of the battery reaches the initial charging cut-off voltage. And the voltage of the battery reaches the target charging cut-off voltage. Wherein the initial charging cut-off voltage is the corresponding battery voltage when the battery is charged to the initial target charge capacity at the preset initial charging rate; the target charging cut-off voltage is the corresponding battery voltage when the battery is charged to the cut-off target charge capacity at the preset buffer charging rate; the initial target charge quantity is smaller than the cut-off target charge quantity. And the battery is charged to the pre-
