PROBLEM TO BE SOLVED: To cool a plurality of power storage cells configuring a power storage pack uniformly.SOLUTION: A power storage pack P is configured by juxtaposing a first power storage module M1 and a second power storage module M2, each laminating a plurality of power storage cells C in the lamination direction, in the width direction. Cooling medium supplied from a suction duct 38, provided along one external surface of the first power storage module M1 in the width direction, cools the power storage cells C of the first power storage module M1 and flows into an intermediate duct 42. The cooling medium mixed in the intermediate duct 42 and having a uniform temperature cools the power storage cells C of the second power storage module M2, before being discharged to an exhaust duct 39 provided along the other external surface of the second power storage module M2 in the width direction. Since both ends of the intermediate duct 42 in the lamination direction are closed with seal members 43, the cooling medium in the intermediate duct 42 is prevented from leaking to the outside, and cooling efficiency of the power storage cells C can be enhanced. |
