Abstract
An undercarriage-mounted battery pack is provided that includes a foot well cavity that is aligned with the foot well corresponding to one or more of the vehicle's seats, e.g., the rear vehicle seats. A portion of the battery pack is located in front of the foot well cavity while a second portion is located behind the foot well cavity, where the two portions are coupled together using conduits. The bottom surface of the battery pack may be shaped in order to minimize drag and enhance the flow of air under the vehicle. The battery pack may include cross-members, either interposed between battery subassemblies or incorporated into the subassembly enclosures, to increase side impact resistance and provide further protection to the batteries within the pack as well as the vehicle's occupants.
