Abstract

A battery module includes a housing component that delimits a module interior and is intended for accommodating at least one module component. The housing component is formed as one piece and delimits the module interior at least on three sides.

First claim

The invention claimed is:

1. A battery module comprising:
a housing component that delimits a module interior and is configured to accommodate at least one module component,

wherein:
the housing component is formed as one piece and delimits the module interior on at least three sides,
the housing component has a bottom side and two side walls that extend spaced apart from one another and in a perpendicular manner with respect to the bottom side,
the housing component comprises mounting areas integrated in the housing component,
the mounting areas are configured to mount the battery module in a housing of a traction battery, and
the mounting areas are located on the bottom side of the housing component.

2. The battery module of claim 1 , wherein the two side walls comprise cutouts.

3. The battery module of claim 1 , wherein the housing component is formed as a bent metal sheet.

4. The battery module of claim 1 , wherein the housing component comprises a molded material or is formed as a molded part.

5. The battery module of claim 1 , wherein the module interior accommodates the at least one module component, and the at least one module component comprises battery cells, power electronics, a battery control system, an air-conditioning system, and/or cables.

6. The battery module of claim 1 , wherein the housing component comprises attachment areas configured to attach the at least one module component.

7. The battery module of claim 6 , wherein the attachment areas are formed as one piece with the housing component.

8. The battery module of claim 6 , wherein the at least one module component comprises at least two different module components.

9. A traction battery comprising:
a housing; and
at least two battery modules,

wherein:
the at least two battery modules are mounted in the housing,
each battery module comprises a housing component that delimits a module interior and is configured to accommodate at least one module component, wherein the housing component is formed as one piece and delimits the module interior on at least three sides,
the housing component has a bottom side and two side walls that extend spaced apart from one another and in a perpendicular manner with respect to the bottom side,
the housing component comprises mounting areas integrated in the housing component,
the mounting areas are configured to mount the battery module in the housing of the traction battery, and
the mounting areas are located on the bottom side of the housing component.

10. The traction battery of claim 9 , wherein a first battery module of the at least two battery modules accommodates at least one battery cell and a second battery module of the at least two battery modules accommodates a battery control system, an air-conditioning system and/or cables.

11. The traction battery of claim 9 , wherein the at least two battery modules are arranged in rows adjacent to one another in a longitudinal direction of the housing.

12. The traction battery of claim 9 , wherein the at least two battery modules are arranged one above the other.

13. The traction battery of claim 9 , wherein the housing component is formed as a bent metal sheet.

14. The traction battery of claim 9 , wherein the housing component comprises attachment areas configured to attach the at least one module component.

15. The traction battery of claim 14 , wherein the attachment areas are formed as one piece with the housing component.
