Cut-off voltage control method and system and electronic equipment

The invention discloses a cut-off voltage control method and system and electronic equipment, and belongs to the technical field of batteries, and the method comprises the steps: determining that the cell temperature of a battery is in a first temperature interval, and the residual capacity of the battery is smaller than or equal to a capacity threshold value; in response to the condition that the discharge rate of the battery is smaller than or equal to a first discharge threshold, adjusting the cut-off voltage of the battery to a first voltage value; in response to the discharge rate being greater than a second discharge threshold, adjusting the cut-off voltage to a second voltage value; wherein the second discharge threshold value is larger than the first discharge threshold value, the first voltage value is larger than the second voltage value, and the first temperature interval is represented as the range of the rated working temperature of the battery. According to the method provided by the invention,
