Abstract

A battery module includes a battery array including a plurality of battery cells arranged in a first direction and a plurality of separation barriers respectively interposed among the battery cells, side frames at two opposite sides of the battery array along the first direction, and at least one reinforcing barrier between two adjacent battery cells in the battery array, the reinforcing barrier having a metal member in a surface facing a corresponding side frame, and the metal member being fixed to the corresponding side frame.

First claim

What is claimed is:

1 . A battery module, comprising:
a battery array including a plurality of battery cells arranged in a first direction and a plurality of separation barriers respectively interposed among the battery cells; side frames at two opposite sides of the battery array along the first direction; and at least one reinforcing barrier between two adjacent battery cells in the battery array, the reinforcing barrier having a metal member in a surface facing a corresponding side frame, and the metal member being fixed to the corresponding side frame.

2 . The battery module as claimed in claim 1 , wherein the reinforcing barrier is positioned at a center of the barrier array, based on the first direction.

3 . The battery module as claimed in claim 1 , wherein the reinforcing barrier is wider than one separation barrier along the first direction.

4 . The battery module as claimed in claim I, wherein the metal member includes a same material as the side frame.

5 . The battery module as claimed in claim 4 , wherein the metal member and the side frame include stainless steel.

6 . The battery module as claimed in claim 1 , wherein the metal member includes:
an inserting portion inserted and fixed inside the reinforcing barrier; a welding portion exposed to an outside of the reinforcing barrier, the welding portion being fixed to the side frame; and an extending portion extending from the inserting portion to the welding portion through a surface of the reinforcing barrier.

7 . The battery module as claimed in claim 6 , wherein a width of the inserting portion is wider than that of the extending portion along the first direction.

8 . The battery module as claimed in claim 6 , wherein a width of the welding portion is wider than that of the extending portion along the first direction.

9 . The battery module as claimed in claim 1 , wherein the metal member and the reinforcing barrier are injection molds.

10 . The battery module as claimed in claim 1 , wherein upper and lower end portions of the side frame are bent portions respectively bending toward upper and lower surfaces of the battery array.

11 . The battery module as claimed in claim 10 , further comprising a buffer member between the bent portions of the side frame and the battery array.

12 . The battery module as claimed in claim 1 , wherein the metal member of the at least one reinforcing barrier is exposed through the surface of the reinforcing barrier to an exterior of the reinforcing barrier.

13 . The battery module as claimed in claim 1 , wherein at least one separation barrier among the plurality of separation barriers is the at least one reinforcing barrier.

14 . The battery module as claimed in claim 1 , wherein only one of a reinforcing barrier or a separation barrier is between every two adjacent battery cells.

15 . A method of manufacturing a battery module, the method comprising:
arranging a plurality of battery cells in a first direction and a plurality of separation barriers respectively interposed among the battery cells to define a battery array; arranging side frames at two opposite sides of the battery array along the first direction; and affixing at least one reinforcing barrier between two adjacent battery cells in the battery array, the at least one reinforcing barrier including metal member in a surface facing a corresponding side frame, and the metal member being fixed to the corresponding side frame by soldering or welding.

16 . The method as claimed in claim 15 , wherein the metal member and the reinforcing barrier are formed through injection molding.
