## Abstract

A battery module and a battery pack including the same are provided. The battery module includes a battery cell stack in which a plurality of battery cells including protruded electrode leads are stacked, the battery cell including protruding portions respectively formed at both ends of a lower edge of the battery cell, a module frame that houses the battery cell stack, and busbar frames disposed to a front and a rear of the battery cell stack where the electrode leads are protruded, at least one of the busbar frames including a guide portion extending to a lower surface of the battery cell stack, the guide portion comprising a guide groove into which the protruding portion is inserted, and the guide groove including an adjusting portion of which a width becomes narrower from where the battery cell is positioned to where the busbar frame is positioned.

## Claims

### Claim 1

A battery module comprising:
a battery cell stack in which a plurality of battery cells including protruded electrode leads are stacked;
a module frame that houses the battery cell stack; and
busbar frames disposed to a front and a rear of the battery cell stack where the electrode leads are protruded,
wherein the battery cell includes protruding portions respectively formed at both ends of a lower edge of the battery cell,
wherein at least one of the busbar frames include a guide portion extending to a lower surface of the battery cell stack,
wherein the guide portion comprises a guide groove into which the protruding portion is inserted,
wherein the guide groove includes an adjusting portion of which a width becomes narrower from where the battery cell is positioned to where the busbar frame is positioned, and
wherein the protruding portion is obliquely bent by the adjusting portion to reduce a height of the busbar frame.

### Claim 2 (depends on 1)

The battery module of claim 1, wherein, when the busbar frame is disposed to the front or the rear of the battery cell stack, the protruding portion of the battery cell is inserted into the guide groove.

### Claim 3 (depends on 1)

The battery module of claim 1, wherein the adjusting portion is opened in a direction to where the battery cell is located.

### Claim 4 (depends on 1)

The battery module of claim 1, wherein the guide groove comprises an inner portion that is farther from the battery cell than the adjusting portion, and
the protruding portion is inserted into the inner portion.

### Claim 5 (depends on 1)

The battery module of claim 1, wherein the adjusting portion comprises a first side and a second side that face each other, and
the first side and the second side become closer from where the battery cell is positioned to where the busbar frame is positioned.

### Claim 6 (depends on 5)

The battery module of claim 5, wherein the first side forms an inclined plane oblique to a protruding direction of the electrode lead, and
wherein, when the protruding portion is inserted into the guide groove, the first side is positioned corresponding to the protruding portion.

### Claim 7 (depends on 6)

The battery module of claim 6, wherein the second side is parallel with the protruding direction of the electrode lead.

### Claim 8 (depends on 1)

The battery module of claim 1, wherein the guide groove is formed in a plurality to correspond to each of the plurality of battery cells.

### Claim 9 (depends on 1)

The battery module of claim 1, wherein a busbar is mounted to the busbar frame, and
the electrode lead is bonded to the busbar.

### Claim 10 (depends on 1)

A battery pack comprising the battery module of claim 1.
