Zusammenfassung:	An apparatus for flexible DC fast charging of an electrified vehicle includes a charge receptacle and a vehicle charging controller programmed to establish a wireless communication with a charging station. The apparatus further includes a reconfigurable energy storage system selectively and electrically connected to the charge receptacle. The reconfigurable energy storage system includes a first rechargeable energy storage device selectively and electrically connected to the charge receptacle, a second rechargeable energy storage device selectively connected to the charge receptacle, and a plurality of low-loss switching devices selectively connected to the first rechargeable energy storage device and the second rechargeable energy storage device. The vehicle charging controller is programmed to selectively actuate the plurality of low-loss switching devices based on the charging voltage of the charging station such that a nominal voltage of the reconfigurable energy storage system matches the charging voltage of the charging station.
