Abstract: An electric storage device includes a first connection plate, a second connection plate, a fastening member, and a plurality of storage modules. The plurality of storage modules are provided between the first connection plate and the second connection plate in a stacking direction. Each of the plurality of storage modules includes a plurality of rectangular storage cells stacked in the stacking direction to provide a stack of storage cells. The plurality of storage modules are arranged next to each other in a direction that crosses the stacking direction. The plurality of storage modules are clamped between the first connection plate and the second connection plate and fastened together by the fastening member. At least one of the first connection plate and the second connection plate is fastened to the plurality of storage modules in the stacking direction by the fastening member.

Abstract: A wiring module includes an insulating protector. The insulating protector includes a main body and a lid. The main body includes a holding portion that holds at least one of an element connecting member and an external connecting member. The lid is attached to the main body. The lid swings between an open position and a closed position. The holding portion is open at the open position and closed at the closed position. The lid includes a shaft for detachable attachment. The main body includes a shaft holder that receives the shaft and holds the shaft such that rotation of the shaft is allowed. The main body includes a restriction portion to hold the lid to the main body such that the swing of the lid is restricted between the open position and the closed position. The lid includes a restriction portion receiving portion that receives the restriction portion.

Abstract: An electric storage device includes a plurality of storage modules and a first storage-module busbar. The plurality of storage modules each include a storage-cell busbar and a plurality of storage cells. The storage-cell busbar includes a first storage-module terminal at a first end of the storage-cell busbar. The plurality of storage cells are electrically connected to each other with the storage-cell busbar. The first storage-module terminal provided in one of the plurality of storage modules is electrically connected to the first storage-module terminal provided in another of the plurality of storage modules with the first storage-module busbar. The first storage-module terminal includes a first stud bolt which extends through a bolt hole provided in the first storage-module busbar and to which a nut is fastened.

Abstract: An electric storage device includes at least first to third storage modules and storage-module busbars. The at least first to third storage modules each include a plurality of storage cells. The at least first to third storage modules are arranged next to each other. Storage-module terminals of the at least first to third storage modules are adjacent to each other. The storage-module terminals of the at least first to third storage modules are electrically connected to each other with the storage-module busbars. The storage-module busbars includes a long storage-module busbar and a short storage-module busbar. The long storage-module busbar is provided at a first side of the at least first to third storage modules. The short storage-module busbar is provided at a second side of the at least first to third storage modules. The long storage-module busbar is longer than the short storage-module busbar.
