Abstract
A battery array is provided with a battery stack (5) having a plurality of rectangular battery cells (1) stacked together with intervening separators (2), endplates (3) disposed at the ends of the battery stack, and binding bars (4) extending in the battery cell stacking direction and attached to the endplates in a manner that binds both sides of the battery stack. The binding bars are configured as plates of given width extending along the battery stack surfaces. The binding bars and separators fit together in a linked configuration that limits their relative movement in the up-and-down direction.

A battery array comprising:
- a battery stack having a plurality of rectangular battery cells stacked together with intervening separators;
- a first endplate disposed at a first end of the battery stack;
- a second endplate disposed at a second end of the battery stack;
- and
- a binding bar extending in the battery cell stacking direction and attached to the endplates to bind the battery stack,
- wherein each of the separators has an insertion groove recessed inwardly towards a center of the battery stack from a side surface of the battery stack, the insertion grooves being aligned in a line extending along the stacking direction of the rectangular battery cells,
- wherein the binding bar has a vertical section facing the side surface of the battery stack and a horizontal section fitting in the insertion grooves of the separators, and
- wherein the horizontal section and insertion grooves of the separators fit together in a linked configuration that limits their relative movement in a direction which is vertical relative to the horizontal section.
