Abstract

An electric storage device includes first storage modules, a second storage module, an attachment part, and a holding frame. The first storage modules include one first storage module and another first storage module. The attachment part has an attachment surface on which the first storage modules are mounted. The holding frame is disposed between the one first storage module and the second storage module to hold the second storage module. The holding frame includes a first frame member and a second frame member. The first frame member has a first bottom portion connected to the attachment surface. The second frame member has a second bottom portion connected to the attachment surface such that the second bottom portion is disposed between the attachment surface and a lower part of the another first storage module.

Dependent claims

An electric storage device comprising:

a plurality of first storage modules in each of which a plurality of storage cells are stacked;
a second storage module in which a plurality of storage cells are stacked;
an attachment part to which the first storage modules are fixed in line;
and
a holding frame that holds the second storage module above a predetermined first storage module of the first storage modules in a height direction,
wherein the holding frame is divided into at least a first frame member and a second frame member,
wherein the first frame member has a first bottom portion fixed to the attachment part, and
wherein the second frame member has a second bottom portion set below the other first storage module adjacent to the predetermined first storage module and fixed to the attachment part.
