Energy storage apparatus

Abstract:

An energy storage apparatus includes: energy storage devices each including an external terminal, the energy storage devices being arranged in a first direction; a bus bar including a plate-like conductive portion; and a neighboring member disposed between the energy storage devices. The conductive portion includes: a fusible portion where a width size, which is a size in a second direction orthogonal to the first direction, is defined by a pair of edges, the width size being smaller than a width size of other portions of the conductive portion; and a pair of enlarged width portions contiguously formed with both sides of the fusible portion in the first direction, a width size of the pair of enlarged width portions increasing in a direction away from the fusible portion. The fusible portion is disposed at a position where the fusible portion overlaps with the neighboring member, and a size of the neighboring member in the first direction is equal to or more than a size of the fusible portion in the first direction.
