PROBLEM TO BE SOLVED: To suppress a temperature change in a power storage device.SOLUTION: A plurality of battery modules 11 are contained in a box 10. A heat insulation sheet 18 is disposed in the box 10 to cover the battery modules 11. Inner lids 12, 13 and 14 are disposed in openings 10a, 10b, and 10c of the box 10, respectively, and panels 15, 16, and 17 are disposed outside of the inner lids 12, 13, and 14, respectively. Through-holes 12a, 13a, and 14a are formed in the inner lids 12, 13, 14, respectively. Vent holes 15a, 16a, and 17a are formed in the panels 15, 16, and 17, respectively. Even if outside temperature falls in winter, the heat insulation sheet 18 can suppress a temperature fall in a power storage device 2. Furthermore, even if insolation influences the power storage device 2 in addition to an increase in the outdoor temperature in summer, it is possible to cool the interior of the power storage device 2 and release heat from within the power storage device 2 since air enters and exits the power storage device 2 via the vent holes 15a, 16a, and 17a and the through-holes 12a, 13a, and 14a. |
