Classification: CPC B  H  Y | IPC B  H

Claim 0:
1. A system for use with a direct current fast-charging (DCFC) station, the system comprising:
a controller;
a reconfigurable battery system that includes:
a first battery pack and a second battery pack;
a plurality of switches having respective ON/OFF conductive states that are individually commanded by the controller to selectively connect the first battery pack and the second battery pack in either a parallel-connected (P-connected) configuration or a series-connected (S-connected) configuration based on a desired operating mode;

an electric powertrain having one or more electric machines powered via the reconfigurable battery system; and
a first charge port and a second charge port each being connectable to the DCFC station via a corresponding charging cable during a DCFC event in which the first battery pack and/or the second battery pack is recharged via the DCFC station, wherein the first charge port and the second charge port are configured to receive a charging voltage from the DCFC station at a relatively low voltage level or a relatively high charging level depending on the ON/OFF conductive states of the switches;
wherein the controller is configured to selectively charge the reconfigurable battery system via either of the first charge port or the second charge port at the relatively high voltage level.
