Abstract
A battery device housing a large number of secondary batteries, in which the batteries can be cooled efficiently as the effect of excessive vibrations or shock or changes in environmental conditions on the housed secondary batteries is suppressed and as sufficient air-tightness is maintained. The battery device includes a modular casing having a battery housing section in its inside and a large number of terminal openings an outer casing member for housing the modular casing in an accommodating space section and a large number of secondary batteries housed in the battery housing section so that terminal sections are exposed to outside through terminal openings The secondary batteries are connected in series with one another. The modular casing is housed in the outer casing member with a gap p between facing outer and inner peripheries with the interposition of mounting portions The modular casing is provided with a suction unit and an exhaust section for supplying and exhausting cooling air to or from the battery housing section The secondary batteries are accommodated in the battery device so that both ends of the batteries are cemented with an adhesive to the terminal openings and so that the outer peripheries of the batteries face the inner surface of the battery housing section with a gap in-between.
