ABSTRACT:
An air-cooled battery enclosure includes a battery tray frame having a floor section including a plurality of outer slats joined to a lower floor frame. A plurality of corner posts extend upward from the lower floor frame. An array of a plurality of criss-crossed inner slats are joined to the outer slats. Outer side walls join the posts, the outer slats and a set of inner slats in a criss-crossed array of cubbyhole compartments. Each cubby hole compartment contains a battery. A plurality of air spaces are located between respective adjacent walls of the enclosure frame for circulation of cooling gas, such as air. In an alternate embodiment stackable battery trays have outer walls with corrugations to space batteries within the tray from outer walls and an open mesh floor. Criss-crossed internal spring baffles with shallow bends within the trays form spaces for the circulation of cooling gas.
