PROBLEM TO BE SOLVED: To enable compatibility of high cooling performance, insulation performance and miniaturization to secure a rigging space in a power storage device having high voltage and high capacity while uniformalizing the temperature difference in power storge cells.SOLUTION: A power storage device has power storage modules 1a to 1d which have a plurality of power storage cells connected to one another in series, in parallel or in a combination style of series-connection and parallel-connection and are kept to predetermined potential, insulating materials 2, 3a, 3b, and a cooling unit 7. Each of the power storage modules 1a to 1d is configured by arranging power storage cells in a case having a cooling air flow path along the peripheries of barrel portions of the power storage cells, and a plurality of thus-configured power storage modules are combined and connected to one another in series, and arranged so that cooling air is directly introduced from the cooling unit 7 into a cooling air intake port provided to each case. Each of the power storage modules 1a to 1d is integrated with the cooling fan unit through an insulation material 2 to constitute an integral unit 16.SELECTED DRAWING: Figure 1 |
