13. A system for a vehicle comprising:
-
a pair of main contactors configured to transfer electric charge to a traction battery when closed, the battery including a plurality of portions selectively connectable using an interpack switch to transfer electric charge therebetween; and a controller configured to, in response to a request, operate the switch to disconnect the portions and to initiate charging of the portions via the contactors in parallel and at a same time. - View Dependent Claims (14, 15)

16. A system for a vehicle comprising:
-
circuitry configured to selectively connect portions of a traction battery in series or in parallel; and a controller configured to request a charge current from a charge station at a magnitude that is based on whether the portions are connected in series or connected in parallel, and to charge the portions via the charge current. - View Dependent Claims (17, 18, 19, 20)
