An energy management system (ESMS) (11) includes energy storage devices (32, 34, 36) coupled to a vehicle drivetrain (18, 26, 14, 24) and configured to store DC energy, a power electronic conversion system (42) having energy ports (102), the power electronic conversion system (42) comprising a DC electrical converters (104, 106, 108), each DC electrical converter (104, 106, 108) configured to step up and to step down a DC voltage, wherein each of the energy ports (102) is coupleable to each of the energy storage devices (32, 34, 36) and each of the energy ports (102) is coupleable to an electrical charging system (44). The ESMS (11) includes a controller (46) configured to determine a voltage of each energy port (102) having either an energy storage device (32, 34, 36) or a DC electrical charging system (44) coupled thereto, and electrically connect a first energy port to a second energy port such that at least one of the DC electrical converters (104, 106, 108) either steps up or steps down an input DC voltage based on the determined voltage of each energy port (102).
