Battery module
A battery module includes a battery cell; a case housing the battery cell, the case including a conductive material; a bus bar electrically connected to the battery cell, the bus bar including a terminal exposed to outside of the case; and a barrier disposed between the terminal and the case, wherein the barrier comprises a groove in an end of the barrier.
1 . A battery module comprising:
a battery cell;
a case housing the battery cell including an upper plate, a lower plate, a front plate, and a rear plate, the case including a conductive material;
a bus bar electrically connected to the battery cell, the bus bar including a terminal exposed to outside of the front plate of the case; and
an insulating member disposed between the terminal and the front plate of the case,
wherein the insulating member includes a barrier including a groove in an end of the barrier,
wherein the barrier is disposed between the terminal and the case in a first direction, extends in a second direction, and exposed to outside of the insulating member in a third direction,
wherein the second direction is perpendicular to the first direction and the third direction,
wherein the groove is formed in an end of the barrier in the second direction,
wherein the groove includes a depth in the second direction, and
wherein the depth of the groove is the distance from an open surface of the barrier to a recessed bottom surface of the groove.
2 . The battery module of claim 1 , further comprising a cover disposed on the terminal.
3 . The battery module of claim 1 , wherein the barrier is configured to surround a peripheral edge of the terminal.
4 . The battery module of claim 3 , wherein the groove extends along the end of the barrier.
5 . The battery module of claim 4 , further comprising a cover disposed on the barrier,
wherein the cover comprises a protrusion inserted into the groove of the barrier.
6 . The battery module of claim 1 , wherein the groove is provided as a plurality of grooves formed between the terminal and the case.
7 . The battery module of claim 5 , wherein the cover further comprises a hook formed in an end thereof, and
wherein the barrier comprises a locking portion accommodating the hook.
8 . A battery module comprising:
a plurality of battery cells stacked within a case including an upper plate, a lower plate, a front plate, and a rear plate;
the case which includes a conductive material;
an internal bus bar electrically connecting the plurality of the battery cells, the internal bus bar including at least one terminal protruding out of the front plate of the case and configured to be coupled with an external bus bar;
an insulating member disposed between the terminal and the front plate of the case, the insulating member includes a barrier including at least one groove formed at a first end of the barrier;
and a cover disposed on the barrier, the cover comprising at least one protrusion inserted into the at least one groove of the barrier,
wherein the barrier is disposed between the terminal and the front plate of the case in a first direction, extends in a second direction, and exposed to outside of the insulating member in a third direction,
wherein the second direction is perpendicular to the first direction and the third direction,
wherein the at least one groove is formed in the second direction, and
wherein the at least one groove includes a depth in the second direction from an open surface to a recessed bottom surface.
