The 288-cell Volt lithium-ion battery pack comprises four modules in a T shape that fits below the rear seat and in the “tunnel” between the front seats. Bus bars connect the four modules, and a service-disconnect bar connects to the pack contacts (Figure 1). The pack physically divides into plastic-encased slices, or blades, each of which includes two cells. A cooling fin carrying five channels of coolant separates the two cells. Electrically, groups of three cells connect in parallel, and 96 of these groups are in series so that the 288 cells produce 360V with a capacity of 16 kWhr. To prolong battery life, the battery never fully charges or discharges, so it uses only the “middle” 9.4 kWhr of battery energy.
