A charge redistribution apparatus includes a transformer including a primary winding and a plurality of secondary windings. The apparatus also includes a plurality of rectifier circuits, respective ones of which are configured to connect respective ones of the secondary windings across respective groups of a plurality of serially connected energy storage devices (e.g., respective individual cells, respective batteries and/or respective strings of batteries). The apparatus further includes a switch configured to connect the primary winding across the plurality of serially connected energy storage devices, and a control circuit configured to control the switch. The control circuit may be configured to cause the switch to alternately connect and disconnect the primary winding to and from the string of serially connected energy storage devices to redistribute charge among the energy storage devices.
