Abstract

A battery module including a plurality of battery cells aligned in one direction, each battery cell of the plurality of battery cells including a terminal portion on one surface thereof; and a housing on outer surfaces of the plurality of battery cells, wherein the housing includes a bending portion on at least one surface thereof, the bending portion protruding toward one battery cell of the plurality of battery cells.

First claim

What is claimed is:

1 . A battery module, comprising:
a plurality of battery cells aligned in one direction, each battery cell of the plurality of battery cells including a terminal portion on one surface thereof; and a housing on outer surfaces of the plurality of battery cells, wherein the housing includes a bending portion on at least one surface thereof, the bending portion protruding toward at least one battery cell of the plurality of battery cells.

2 . The battery module as claimed in claim 1 , wherein the bending portion has elasticity.

3 . The battery module as claimed in claim 1 , wherein the bending portion has a through-region in a portion thereof that contacts the battery cell.

4 . The battery module as claimed in claim 1 , wherein the bending portion has a recessed portion in a portion thereof that contacts the battery cell.

5 . The battery module as claimed in claim 1 , wherein the bending portion faces another surface of one of the battery cells, the another surface being opposite to the one surface that has the terminal thereon.

6 . The battery module as claimed in claim 1 , wherein the housing further includes:
a pair of end plates that respectively contact outermost battery cells of the plurality of battery cells; and an accommodating portion coupled with the pair of end plates, the accommodating portion surrounding: another surface of one of the battery cells, the another surface being opposite to the one surface, and side surfaces that connect between the one surface and the another surface of the one battery cell.

7 . The battery module as claimed in claim 6 , wherein the bending portion is in the accommodating portion.

8 . The battery module as claimed in claim 6 , wherein the housing further includes a top plate that covers the one surface of the one battery cell.

9 . The battery module as claimed in claim 8 , wherein the plurality of battery cells are pressed to the top plate by elastic force from the bending portion.

10 . The battery module as claimed in claim 1 , wherein the bending portion faces a side surface of a battery cell of the plurality of battery cells.

11 . The battery module as claimed in claim 1 , wherein the bending portion is elastically biased toward the plurality of battery cells.
