BATTERY PACK AND VEHICLE INCLUDING THE SAME
First Claim
1. A battery pack comprising:
- a battery assembly including a plurality of rectangular battery cells that are arranged side by side;
a pair of end plates that are arranged on the side-by-side arrangement directional end surfaces of the battery assembly; and
a plurality of metal bind bars that couple said end plates, which are arranged on the end surfaces of said battery assembly, to each other,wherein each of the bind bars includes bent parts that are formed by bending the both end parts of the bind bar toward a common direction, and the bind bar is formed in a substantially rectangular U shape as viewed from the bar edge side by forming the bent parts by bending the both end parts of the bind bar, wherein the bent parts on the both ends of the bind bar are coupled to said end plates so that said battery assembly is interposed and secured between the end plates,wherein said bent part includes a bent-part-side engagement structure in a coupling area of the bent part to be coupled to said end plate,wherein said end plate includes an end-plate-side engagement structure that is positioned so as to face said bent part, andwherein said end plates are securely held by the bind bars when said bent-part-side engagement structures of the bind bars engage with the end-plate-side engagement structures of the end plates.

Abstract
A battery pack includes a battery assembly constructed of rectangular battery cells that are arranged side by side. End plates are arranged on the end surface of the assembly. Metal bind bars securely hold the assembly and the plates. Each bar includes bent parts that are formed by bending the both bar end parts toward a common direction. The bar is formed in a substantially rectangular U shape as viewed from the bar edge side The bent parts on the both bar ends are coupled to the plates so that the assembly is interposed and secured between the plates. A bent-part-side engagement structure is formed in a coupling area of the bent part of the bar. An end-plate-side engagement structure is positioned in the plate to face the bent part. When the bent-part-side and end-plate-side engagement structures engage with each other, the bar is fastened to the plates.
