A modular battery pack system includes a battery pack and controller. The battery pack has first and second battery modules interconnected via electrical cables, with each module having a battery cell string. The pack has first, second, and third electrical connectors and four switches that selectively connect the strings to one or more of the electrical connectors. A DC charging connector is electrically connected to one of the cables between the first electrical connectors of the battery modules, and electrically connects the pack to an off-board DC fast-charging station. In response to input signals corresponding to a requested mode, the controller commands an open/closed state of each of the switches, via switching control signals, to establish a series charge mode, a parallel charge mode, and one or more of a series and/or parallel drive mode of the battery pack. A motor vehicle includes the system.
