Abstract
Cylindrical battery modules ( ) composed of a plurality of serially connected cells ( ) and arranged in parallel and stacked in piles within a holder case ( ) are cooled with a forced current of air supplied from the underside. The battery modules ( ) located on the most upstream side of the air current are covered with film tubes ( ), so as to prevent them from being cooled more than the other battery modules ( ), thereby achieving uniformity in the temperatures of the battery modules. Temperature equalization is further improved by providing film tubes ( ) to the several tiers of the battery modules such that the film tubes for covering upstream battery modules ( ) have larger diameters than those for downstream battery modules.
