A battery cell balancing system includes N switching circuits connected to first terminals and second terminals of N battery cells, respectively, where N is an integer greater than one. A first transformer includes a first core and N sets of windings wound around the first core. The N sets of windings are connected to the N switching circuits, respectively. A first control module controls switching of the N switching circuits to reverse first connections between the first terminals and the second terminals of the N battery cells and the N sets of windings, respectively, at a first frequency to balance charge levels of the N battery cells. |
