CELL BLOCK

摘要

A cell block includes holding sections that hold a battery cell arrayed body of a lower layer between a lower holding frame member and a middle holding frame member, hold a battery cell arrayed body of an upper layer between the middle holding frame member and an upper holding frame member, and hold the battery cell arrayed body of the upper layer and the battery cell arrayed body of the lower layer in a state displaced from each other in the row direction. Lower fastening sections are disposed at positions below a battery cell and projects in the row direction beyond the battery cell arrayed body of the lower layer, and join the lower holding frame member and the middle holding frame member with each other by fastening.

主权项

1. A cell block of at least two battery cell arrayed bodies configured by disposing cylindrical battery cells in parallel, and the at least two battery cell arrayed bodies by at least three holding frame members in a stacking direction of the battery cell arrayed bodies, the cell block comprising:
holding sections that hold a battery cell arrayed body of a lower layer between a lower holding frame member and a middle holding frame member, hold a battery cell arrayed body of the upper layer between the middle holding frame member and an upper holding frame member, and hold the battery cell arrayed body of the upper layer and the battery cell arrayed body of the lower layer displaced from each other in a row direction; lower fastening sections that are disposed at positions below a battery cell that projects to one side in the row direction beyond the battery cell arrayed body of the lower layer out of battery cells composing the battery cell arrayed body of the upper layer, and joining the lower holding frame member and the middle holding frame member with each other by fastening; and upper fastening sections that are disposed at positions above a battery cell that projects to one side in the row direction beyond an upper layer battery cell arrayed body of battery cells composing a lower layer battery cell arrayed body, and joining the middle holding frame member and the upper holding frame member with each other by fastening.
