<p>PROBLEM TO BE SOLVED: To solve problems, for example, when heat generated from a battery body is transmitted to a storage space on outside of a battery cover, air in the storage space is heated, and the heated air heats cooling air flowing in an inlet duct, resulting in reduction of cooling efficiency of the battery body.SOLUTION: A branch duct 40 which is branched from an inlet duct 38 is provided. The branch duct 40 introduces cooling air to a storage space 14. The cooling air introduced from the branch duct 40 performs air ventilation in the storage space 14.</p> |
