Abstract

A battery module and a vehicle including the same are disclosed. According to an exemplary embodiment of the present invention, the battery module may include: a plurality of battery cells; a housing configured to include a base plate, a housing frame, and a cover plate; and a gasket interposed between the housing frame and the base plate and between the housing frame and the cover plate, wherein an upper flange of the housing frame facing the cover plate and a lower flange of the housing frame facing the base plate have a step shape forming a recess portion opened to an inner side of the housing plate, and the gasket is disposed in the recess portion.

Claims

1. A battery module comprising:

a plurality of battery cells;

a housing configured to include a base plate, a housing frame, and a cover plate; and

a gasket interposed between the housing frame and the base plate and between the housing frame and the cover plate,

wherein an upper flange of the housing frame facing the cover plate and a lower flange of the housing frame facing the base plate have a step shape forming a recess portion opened to an inner side of the housing plate, and

the gasket is disposed in the recess portion.

2. The battery module of claim 1, wherein

the gasket is attached to the base plate and the cover plate.

3. The battery module of claim 2, wherein

the gasket is a foam gasket formed by providing a foaming agent to each of the base plate and the cover plate.

4. The battery module of claim 1, wherein

a width of the recess portion has a range of 1:

5 to 1;

2 with respect to a total width of the upper flange and the lower flange.

5. The battery module of claim 1, wherein

a width of the recess portion has a range of 3:

1 to 1.2;

1 with respect to a width of the gasket.

6. The battery module of claim 1, wherein

a depth of the recess portion has a range of 1:

1.1 to 1;

2 with respect to a height of the gasket.

7. The battery module of claim 1, wherein

the recess portion includes a flange surface extending in a direction intersecting the inner side of the housing frame and a circumferential protrusion disposed on the flange surface of the recess portion.

8. The battery module of claim 7, wherein

the gasket is disposed at an upper side of the circumferential protrusion.

9. The battery module of claim 8, wherein

The circumferential protrusion has a height h2, and the recess portion has a height h3, and

a ratio of the height h3 to the height h2 is in a range of 2:

1 to 5;

1.

10. A vehicle comprising a battery module according to claim 1.
