## Abstract

Discussed is a battery module that may include a battery cell stack in which a plurality of battery cells are stacked, a module frame that houses the battery cell stack; and at least one venting part on an upper part of the module frame, wherein at least one edge of the at least one venting part may be connected to the upper part of the module frame, and a remaining edge of the at least one venting part may be formed by the upper part of the module frame that is cut open.

## Claims

### Claim 1

A battery module comprising:
a battery cell stack in which a plurality of battery cells are stacked;
a module frame that houses the battery cell stack; and
at least one venting part on an upper part of the module frame,
wherein at least one edge of the at least one venting part is connected to the upper part of the module frame, and a remaining edge of the at least one venting part is formed by the upper part of the module frame that is cut open,
wherein the remaining edge includes a plurality of edges that are cut open,
wherein the plurality of edges that are cut open in the venting part are connected to each other,
wherein the plurality of edges that are cut open include a pair of length edges extending in a longitudinal direction of the module frame and a width edge extending in a width direction of the module frame and located between the pair of length edges, and
wherein each of the pair of length edges has lengths that are greater than a length of the width edge.

### Claim 2 (depends on 1)

The battery module of claim 1, wherein:
based on the at least one edge connected to the upper part of the module frame in the venting part, the venting part is configured to be lifted diagonally from the upper part of the module frame toward an outside thereof.

### Claim 3 (depends on 2)

The battery module of claim 2, further comprising:
a first busbar frame that covers a front surface of the battery cell stack and to which a terminal busbar is connected;
a second busbar frame that covers a rear surface of the battery cell stack and to which a module connector is connected; and
a first end plate and a second end plate that are coupled to the module frame, and cover the first busbar frame and the second busbar frame, respectively.

### Claim 4 (depends on 3)

The battery module of claim 3, wherein:
in the at least one venting part, the at least one edge connected to the upper part of the module frame is located adjacent to the first end plate.

### Claim 5 (depends on 3)

The battery module of claim 3, wherein:
in the at least one venting part, the at least one edge connected to the upper part of the module frame extends along a along the width direction of the module frame.

### Claim 6 (depends on 3)

The battery module of claim 3, wherein:
the at least one venting part is configured to be lifted so that any high-temperature heat, gas, and flames are vented in a direction in which the second end plate is disposed.

### Claim 7 (depends on 3)

The battery module of claim 3,
wherein the at least one venting part comprises at least two venting parts, and
wherein the at least two venting parts are spaced apart from each other-along a along the longitudinal direction of the module frame.

### Claim 8 (depends on 7)

The battery module of claim 7, wherein:
the at least two venting parts are disposed in a same direction as each other.

### Claim 9 (depends on 3)

The battery module of claim 3, wherein:
the terminal busbar is connected to an external busbar that allows connection with other battery modules adjacent to the battery module including the terminal busbar.

### Claim 10 (depends on 1)

A battery pack comprising the battery module of claim 1.

### Claim 11 (depends on 1)

The battery module of claim 1, wherein the width edge is perpendicular to the pair of length edges.
