Abstract: A battery tray apparatus for receiving and retaining a plurality of batteries includes a body portion having a length and a width. The body portion includes a plurality of first ridge portions extending along the length of the body portion and a plurality of second ridge portions extending along the width of the body portion. The plurality of second ridge portions intersects the plurality of first ridge portions. The plurality of first ridge portions and the plurality of second ridge portions define a plurality of recessed portions for receiving the plurality of batteries and preventing movement of the plurality of batteries relative to the body portion.

Abstract: A battery pack for an electric/hybrid vehicle including a cooling system that provides a substantially uniform cooling of the batteries within the pack. The battery pack includes a base that supports the batteries stacked in layers one atop the other. Each battery includes a plurality of cells with cooling air channels between them. A retention frame overlays and is affixed to the batteries to restrict the movement of the batteries within the pack. The batteries are held in spacers disposed above and below each layer of batteries. The spacers provide air passages above and below the batteries to allow cool air to flow across the batteries and through the cooling channels. An inlet admits cool air into the pack and an outlet releases the air from the pack after it is has passed through the stack of batteries. A front manifold is connected to the inlet and includes a plurality of separate runners for evenly splitting the air between the spacers below each layer of batteries.
