A battery tray for an electric vehicle includes a tub component that has a floor portion and a perimeter wall portion that integrally extends upward around a peripheral edge of the floor portion to border a battery containment area of the tub component. The tub component may include a plurality of cross member portions that integrally interconnect with the floor portion and the perimeter wall portion so as to span laterally across the battery containment area to divide the battery containment area into separate compartments. A support structure of the battery tray may have an elongated member coupled at an exterior side of each of opposing longitudinal sections of the perimeter wall portion of the tub component.

Battery packs that include a housing, a plurality of rechargeable battery cells within the housing, and a plurality of thermoelectric generators. The plurality of thermoelectric generators are within the housing and are positioned proximate to and in thermal communication with the plurality of rechargeable battery cells.
