PROBLEM TO BE SOLVED: To restrain deterioration of temperature adjusting efficiency to a battery due to heat exchange with ambient air.SOLUTION: A housing region S1 housing a first battery stack 11 and a second battery stack 12 is formed at a center inside a case 10. A first partition wall 31 for forming a first temperature control flow path 21 in which a heat medium is circulated after circulating through the housing region S1 is provided between the housing region S1 and a first side wall 10b. A first inflow path 24 is formed between the first battery stack 11 and the first partition wall 31. A temperature control device 40 is provided adjacent to the first inflow path 24 via the first partition wall 31. An induction wall 51 as an induction member for inducing the heat medium after passing through the first temperature control flow path 21, i.e., the heat medium heated or cooled by the temperature control device 40 to the first inflow path 24 is formed on a flow path reaching the first inflow path 24 from an outflow portion 23 of the first temperature control flow path 21. |
