An EV's primary energy source is a battery pack (Figure 1). A pack is typically designed to fit on the vehicle's underside, between the front and back wheels, and occupies the space usually reserved for a transmission tunnel, exhaust, and fuel tank in an internal combustion vehicle. Keeping the pack as low as poss
