International ClassH01M 010/46AbstractAn apparatus and method are disclosed for equalizing individual module voltages in a multiple module battery pack during recharging. Two individual module voltages are compared, and charge redistribution is caused to occur by way of switched mode converters when the voltages are not equivalent. Switched mode converters may be of unidirectional or bidirectional topologies.Other References
