## Abstract

A battery pack including a battery cell; a protection circuit module (PCM) electrically coupled to the battery cell; a case including internally defined positions for housing the battery cell and the PCM and having a hole; a connector extending through the hole and protruding from the case, the connector electrically coupling the battery cell to an external device; and a sealing member located substantially parallel to an extending direction of the connector and adjacent to an inner side of the case and sealing the hole.

## Claims

### Claim 1

A battery pack comprising:
a battery cell;
a protection circuit module (PCM) electrically coupled to the battery cell;
a case comprising internally defined positions for housing the battery cell and the PCM and having a hole;
a connector extending through the hole and protruding from the case, the connector electrically coupling the battery cell to an external device; and
a sealing member in the case and located substantially parallel to an extending direction of the connector and adjacent to an inner side of the case and sealing the hole.

### Claim 2 (depends on 1)

The battery pack of claim 1, wherein the hole is in a side of the case, and the side extends in a thickness direction of the case.

### Claim 3 (depends on 1)

The battery pack of claim 1, wherein the sealing member comprises a fire-retardant material.

### Claim 4 (depends on 1)

The battery pack of claim 1, wherein a height of the sealing member is greater than a height of the hole.

### Claim 5 (depends on 1)

The battery pack of claim 1, wherein a cross-sectional size of the sealing member is greater than a cross-sectional size of the hole.

### Claim 6 (depends on 1)

The battery pack of claim 1, wherein a cable extends from an end of the PCM through the sealing member and electrically couples the PCM to the connector.

### Claim 7 (depends on 1)

The battery pack of claim 1, wherein the sealing member is between an end of the PCM and the inner side of the case.

### Claim 8 (depends on 7)

The battery pack of claim 7, wherein the end of the PCM contacts the sealing member, and a first outer side of the sealing member contacts the inner side of the case.

### Claim 9 (depends on 7)

The battery pack of claim 7, wherein a first outer side of the sealing member contacts the inner side of the case, and a second outer side of the sealing member, opposite to the first outer side, faces the end of the PCM.

### Claim 10 (depends on 1)

The battery pack of claim 1, wherein the case has a frame shape comprising a side wall extending in a thickness direction and substantially surrounding the battery cell and the PCM, and a lower rib extending vertical to the side wall and having a space configured for loading the PCM.

### Claim 11

A battery pack comprising:
a battery cell;
a protection circuit module (PCM) electrically coupled to the battery cell;
a case comprising internally defined positions for housing the battery cell and the PCM and having a hole;
a cable coupling a connector to the PCM and protruding through the hole; and
a sealing member substantially parallel to a protrusion direction of the connector and sealing the hole.

### Claim 12 (depends on 11)

The battery pack of claim 11, wherein a first outer side of the sealing member contacts an inner side of the case, and the sealing member comprises a fire-retardant material.

### Claim 13 (depends on 12)

The battery pack of claim 12, wherein a second outer side of the sealing member, opposite to the first outer side, faces an end of the PCM.

### Claim 14 (depends on 11)

The battery pack of claim 11, wherein the cable extends through the sealing member.

### Claim 15 (depends on 11)

The battery pack of claim 11, wherein the hole is in a side of the case, and the side extends in a thickness direction of the case.

### Claim 16

A battery pack comprising:
a battery cell;
a protection circuit module (PCM) electrically coupled to the battery cell;
a case comprising internally defined positions for housing the battery cell and the PCM and having a hole;
a connector extending through the hole and protruding from the case, the connector electrically coupling the battery cell to an external device; and
a sealing member between an end of the PCM and an inner side of the case and sealing the hole.

### Claim 17 (depends on 16)

The battery pack of claim 16, wherein a cable electrically couples the connector to the PCM and extends through the sealing member.

### Claim 18 (depends on 16)

The battery pack of claim 16, wherein a first outer side of the sealing member contacts an inner side of the case.

### Claim 19 (depends on 16)

The battery pack of claim 16, wherein the sealing member comprises a fire-retardant material.

### Claim 20 (depends on 16)

The battery pack of claim 16, wherein a height of the sealing member is greater than a height of the hole.

### Claim 21 (depends on 1)
