Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a method and apparatus for equalizing charging of a power battery, a control device, and a storage medium. The method comprises: determining a first voltage difference between a first battery cell and a second battery cell of a power battery, wherein the first battery cell is the cell that has the highest current voltage, and the second battery cell is the cell that has the lowest current voltage; when the first voltage difference is greater than a target voltage difference, controlling the first battery cell to discharge; determining a second voltage difference between the voltage of the first battery cell and a first target voltage; adjusting the charging current on the basis of the second voltage difference; and charging the power battery on the basis of the adjusted charging current.
