Abstract
This invention provides an energy storage device that can suppress the adverse effects on electrical equipment caused by water entering the inside of the enclosure. [Solution] In an energy storage device (1) according to one embodiment of the present disclosure, the housing (3) comprises a frame (5) which can be assembled by fastening members and has column units (5a) and beam members (5b) connecting the column units (5a), a partition member (6) which can be fixed to the frame (5) by fastening members and partitions the inside of the housing (3) into a space for housing electrical equipment (14) and other spaces, and a crown member (7) which is fixed to the frame (5). The partition member (6) has water-sealing portions (6c) at both the left and right ends of the partition member (6), and the water-sealing portions (6c) are covered by the crown member (7) when positioned above the electrical equipment (14).
