SHOVEL

An upper rotating body is rotatably mounted on a lower running body. A power storage module is mounted on the upper rotating body. The power storage module includes a plurality of power storage cells. Each of the plurality of power storage cells accumulates electric energy. A heat absorbing plate is disposed between the power storage cells. The heat absorbing plate is thermally coupled to the power storage cells, and a flow channel circulating cooling medium is formed in the inner portion of the heat absorbing plate. A cooling medium supply device makes the cooling medium flow into the flow channel formed in the inner portion of the heat absorbing plate.
