An energy storage system (100) for supporting dual electrical functions of a vehicle (10) includes an energy storage unit (400) having a plurality of energy storage modules (478, 420, 424) connected in series, a plurality of sensing units for sensing state of charges of the plurality of energy storage modules, and a pair of primary voltage terminals (404, 405). The series connected plurality of energy storage modules (418, 420, 424) is connectable across the pair of primary voltage terminals (404, 405) during a key-on state of the vehicle (10) to supply energy storage power at a first voltage level to support primary electrical functions of the vehicle (10). The energy storage system (100) is further configured to select a subset of the plurality of energy storage modules (418, 420, 424) during a key-off state of the vehicle (10) to connect across a pair of secondary voltage terminals(415, 416) using a switch network (BMS 104) to supply energy storage power at a second voltage level. |
