Claim 10:
11. A method for charging a reconfigurable battery system of an electrical system having a first battery pack and a second battery pack using a direct current fast-charging (DCFC) station, the method comprising:
verifying, via a controller, a connection of a first charging cable and a second charging cable from the DCFC station to a first charge port and a second charge port of the electrical system, respectively, wherein the first charge port and the second charge port are both configured to receive either of a relatively low charging voltage or a relatively high charging voltage from the DCFC station;
selectively establishing a series-connected (S-connected) configuration of the first and second battery packs, via the controller, by individually commanding respective ON/OFF conductive states of first, second, third, and fourth switches of the reconfigurable battery system; and
charging the reconfigurable battery system via the first charge port or the second charge port when the DCFC station is able to supply the relatively high charging voltage.
