Equalization current adjustment method and related apparatus
First Claim
1. An equalization current adjustment method, the method comprising:
- determining a battery unit to be equalized in a battery pack;
obtaining a current actual equalization current value of the battery unit; and
when a difference between the current actual equalization current value 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 or a voltage gain of the target circuit, so that the difference between the current actual equalization current value and the target equalization current value falls within the range of the preset threshold,wherein the target equalization current value is obtained by a frequency gating battery pack active equalization apparatus according to a current energy status of the battery unit, and the target circuit comprises a circuit component connected to the battery unit, the alternating current power supply, and the battery unit.
