Has been placed.

  The first fan device 47A of the end-side first rack 30A is configured such that the gas in the gaps 38, 39 between the inner wall surfaces 18a, 19a and the end-side first rack 30A is supplied to the center-side first rack 30B. The first fan device 47A of the center side first rack 30B generates a gas flow so that the gas from the end side first rack 30A is supplied to the gaps 40 and 41 with the second rack 60. Generate a flow of

  In addition, the power storage device 10F is installed in a facility having the air conditioning equipment 90, and an opening 91 in which at least a part of the air conditioning equipment 90 is disposed is formed above the container 11E. Inside the opening 91, a gas outlet 92 and a gas recovery port 93 of the air conditioning equipment 90 are arranged.

  In addition, the power storage device 10F includes a guide member 94F that guides the gas from the gas outlet 92. The guide member 94F guides the gas so that the gas from the gas outlet 92 is supplied to the gaps 38 and 39. In the present embodiment, the guide member 94F guides the gas from the gas outlet 92 so that the gas from the gas outlet 92 is supplied to the gaps 38 and 39 and not supplied to the gaps 40 and 41.

  As described above, also in this embodiment, a large number of storage battery modules 45 and 75 can be arranged in the internal space SP of the container 11E. Moreover, in order to cool the 1st storage battery module 45 of the center side 1st rack 30B with the gas which cooled the 1st storage battery module 45 of the edge part 1st rack 30A, the 1st storage battery module of the edge part 1st rack 30B is used. The gas which cooled 45 can be used effectively. Moreover, since the 2nd storage battery module 45 is cooled with the gas which cooled the 1st storage battery module 45, the gas which cooled the 1st storage battery module 45 can be used effectively.

  Also in the present embodiment, it is possible to cool the storage battery modules 45 and 75 by effectively utilizing the air conditioning equipment 90 of the facility where the container 11E is installed, increasing the size of the power storage device 10F, complicating the structure, In addition, an increase in manufacturing cost can be suppressed.

  Also in the present embodiment, the cooling gas from the gas outlet 92 can be supplied in an arbitrary direction using the guide member 94F, and the storage battery modules 45 and 75 can be efficiently cooled.
