A battery system includes: a battery block defining a cooling gap between battery cells composed of a plurality of rectangular/prismatic cells; and a gas blower forcibly blowing the gas through the gap in the block. The block, set in two separate arrays, is provided therebetween with an intermediate duct connected to each of the gaps. An outer duct is provided outside the block set in two separate arrays, and the plurality of gaps are parallel-connected between the outer duct and the intermediate duct. The gas blower forcibly blows the gas from the intermediate duct to the outer duct, and the gas forcibly blown is branched from the intermediate duct to be blown through each of the gaps to cool the cells. The gas having passed through the gaps and cooled the cells is collected at and exhausted from the outer duct. |
