Abstract
The present disclosure relates to a battery current sharing control method and a battery current sharing control system. The method includes: acquiring an actually measured cell array current corresponding to each of cell arrays; determining a target current of all cell arrays based on actually measured cell array currents corresponding to all the cell arrays; and adjusting an output current of each of cell array branches to the target current via adjusting current sharing DCDC converters based on the actually measured cell array currents corresponding to all the cell arrays and the target current. In this way, a capacity loss of the cell arrays caused by connecting in parallel can be reduced, and battery capacity utilization of the cell arrays can be improved.
