<p>PROBLEM TO BE SOLVED: To improve workability when coupling a plurality of power storage modules between a pair of connection plates, while preventing a power storage device from being enlarged in size.SOLUTION: A power storage device P is configured by constituting a power storage module M by stacking a plurality of square power storage cells 11 in a stacking direction, holding a plurality of power storage modules M juxtaposed in a direction crossing the stacking direction between a first connection plate 26A and a second connection plate 26B which are disposed on both sides of the stacking direction, and integrally coupling the power storage modules M by means of bolts 29. Since the first and second connection plates 26A and 26B are coupled in the stacking direction by the bolts 29, even without especially devising shapes of the first and second connection plates 26A and 26B, a distance between a tool for operating the bolts 29 and the first and second connection plates 26A and 26B can be sufficiently secured. Thus, workability of coupling work can be improved and the first and second connection plates 26A and 26B can be reduced in size.</p> |
