A method for balancing states of charge of battery cells of a battery includes determining the individual cell capacities of the cells. A k-th cell having the smallest cell capacity, the individual states of charge, the depth of discharge, a target depth of discharge, and a target state of charge are determined. The deviation of the state of charge of a cell from the target state of charge (DeltaSOCtarget,n) and the minimum deviation of the state of charge of a cell from the target state of charge (DeltaSOCmin) are determined. At least one of the cells, to which DeltaSOCtarget,n-DeltaSOCmin>X applies, where X>=0, is discharged. If DeltaSOCtarget,n-DeltaSOCmin@X applies to all cells, the method ends. If this condition does not apply to all cells, the individual states of charge are determined again and the method is repeated.
