Abstract: The present disclosure provides a method, device, computer apparatus, and readable storage medium for controlling a battery, belonging to the field of processing technology. The method includes obtaining a first initial adjustment factor and a second initial adjustment factor based on the current application scenario of the battery, and obtaining a target output voltage of the battery; monitoring an actual output voltage of the battery in real time; and adjusting, if the difference between the actual output voltage and the target output voltage is greater than a preset threshold, the first initial adjustment factor and/or the second initial adjustment factor based on the target output voltage and the actual output voltage, so as to make the difference between the actual output voltage and the target output voltage less than or equal to the preset threshold.
