Abstract

A battery module comprising a cell assembly comprising a plurality of battery cells, a support frame disposed to face the cell assembly, a plurality of busbars disposed on the support frame and electrically connecting the plurality of battery cells, and a busbar spacer at least partially disposed between the plurality of busbars and provided to maintain the spacing between adjacent busbars among the plurality of busbars.

First claim

What is claimed is:

1 . A battery module comprising:
a cell assembly comprising a plurality of battery cells; a support frame disposed on at least one side of the cell assembly; a plurality of busbars disposed on the support frame and electrically connecting the plurality of battery cells; and a busbar spacer at least partially disposed between the plurality of busbars and separating adjacent busbars among the plurality of busbars.

2 . The battery module of claim 1 , wherein a melting point temperature of the busbar spacer is higher than a melting point temperature of the support frame.

3 . The battery module of claim 1 , wherein the plurality of busbars and the busbar spacer are disposed to face each other with the support frame interposed therebetween.

4 . The battery module of claim 3 , wherein the busbar spacer is disposed between the support frame and the cell assembly, and at least partially protrudes to be disposed between the plurality of busbars.

5 . The battery module of claim 1 , wherein the busbar spacer includes,
a spacer body provided to face the support frame; and a protrusion protruding from the spacer body toward a gap between the plurality of busbars.

6 . The battery module of claim 5 , wherein the protrusion includes,
a first protrusion supporting a first surface of the plurality of busbars, facing the cell assembly; and a second protrusion protruding further than the first protrusion and supporting a second surface opposite to the first surface.

7 . The battery module of claim 6 , wherein the first protrusion includes a first support contacting the first surface of the plurality of busbars,
the second protrusion includes a second support contacting the second surface of the plurality of busbars, and at least one of the plurality of busbars is disposed and inserted between the first support and the second support.

8 . The battery module of claim 5 , wherein the support frame includes a spacer hole provided between the plurality of busbars so that at least a portion of the protrusion is inserted thereinto.

9 . The battery module of claim 6 , wherein the first protrusion and the second protrusion are disposed alternately.

10 . The battery module of claim 6 , wherein at least one first protrusion and at least one second protrusion are provided; and
the first protrusion is disposed between a plurality of the second protrusions.

11 . The battery module of claim 7 , wherein the second support includes a hook on which edges of a plurality of adjacent busbars are caught.

12 . The battery module of claim 5 , wherein the spacer body has a height greater than a height of the plurality of busbars.

13 . A battery module comprising:
a cell assembly including a plurality of battery cells; a support frame disposed to face the cell assembly; a plurality of busbars disposed on the support frame and including a first busbar and a second busbar adjacent to each other; and a busbar spacer at least partially disposed between the first busbar and the second busbar, and coupling the first busbar and the second busbar to each other.

14 . The battery module of claim 13 , wherein the plurality of busbars and the busbar spacer are disposed to face each other with the support frame interposed therebetween; and wherein
the busbar spacer comprises: a spacer body disposed between the support frame and the cell assembly; and a protrusion protruding from the spacer body toward a space between the first busbar and the second busbar.

15 . The battery module of claim 14 , wherein the protrusion includes,
a first protrusion supporting a first surface of the first busbar and the second busbar; and a second protrusion at least partially disposed between the first busbar and the second busbar, and supporting a second surface of the first busbar and the second busbar, opposite to the first surface.

16 . The battery module of claim 15 , wherein the first busbar and the second busbar are configured to be coupled to each other while being at least partially interposed between the first protrusion and the second protrusion.
