<p>PROBLEM TO BE SOLVED: To provide an accumulator battery chassis structure capable of widening a use temperature range of a battery.SOLUTION: A battery housing 2 housing a battery holding part 2a therein has an outer wall 3 and an inner wall 4, and is formed by a double wall in which an interspace 5 is formed between the outer wall 3 and the inner wall 4. A part of the outer wall 3 is provided with an air suction opening 6 and an air exhaustion opening 7. Any one of the suction opening 6 and the exhaustion opening 7 is provided with a louver 8 that can be opened and closed, and the other is provided with a blower 9. A duct 10 for blowing cooling air sucked into the interspace 5 from the suction opening 6 by driving the blower 9, to the exhaustion opening 7 via the interspace 5 is formed. Heat radiation means is provided which performs an operation to open the louver 8 and performs an operation to drive the blower 9 to blow the cooling air into the duct 10 of the interspace 5 and perform heat radiation of a battery main body 1 in the case that a temperature of the battery main body 1 is made higher than an upper limit temperature T1 of a setting temperature range.</p> |
