Abstract
An equalization current adjustment method includes: determining a battery unit to be equalized in a battery pack, and obtaining a current actual equalization current value of the battery unit; and when it is determined that a difference between the current actual equalization current value of the battery unit and a target equalization current value does not fall within a range of a preset threshold, adjusting a fundamental amplitude of an alternating current power supply of a target circuit on which the battery unit is located and/or a voltage gain of the target circuit, so that the difference between the current actual equalization current value of the battery unit and the target equalization current value falls within the range of the preset threshold.
