Abstract

The invention relates to a battery shell, in particular a battery shell of a traction battery, the battery shell being formed from plastics material, the battery shell having a fastening system for fastening a component to the battery shell, the fastening system having a guide rail, an inner profile and a fastening element, the guide rail being integrally or interlockingly connected to the battery shell, the inner profile being guided by the guide rail, the fastening element being designed to establish a connection between the component and the inner profile.

First claim

The invention claimed is:

1. Battery shell of a traction battery, the battery shell being formed from plastics material, the battery shell having a fastening system for fastening a component that is inside the battery shell to the battery shell, wherein the fastening system has
a guide rail,
an inner profile arranged inside the guide rail, and
a fastening element,
the guide rail being integrally or interlockingly connected to the battery shell,
the inner profile being guided by the guide rail, and
the fastening element being designed to establish a connection between the component, which is inside the battery shell, and the inner profile.

2. Battery shell according to claim 1 , wherein the battery shell is produced using a pressing process.

3. Battery shell according to claim 1 , wherein the guide rail has a proportion of at least 90 wt. % metal.

4. Battery shell according to claim 1 , wherein the guide rail has a proportion of at least 90 wt. % plastics material.

5. Battery shell according to claim 1 , wherein the inner profile has a proportion of at least 90 wt. % metal.

6. Battery shell according to claim 1 , wherein at least one fastening element is pressed into the inner profile.

7. Battery shell according to claim 1 , wherein the inner profile has, relative to the guide rail, at least one translational degree of freedom.

8. Traction battery for a motor vehicle having a vehicle mass and the battery shell according to claim 1 .

9. Traction battery according to claim 8 , wherein the inner profile and/or the guide rail has an electrically conductive connection between the component and the vehicle mass.

10. Motor vehicle having a battery shell according to claim 1 .

11. Battery shell according to claim 1 , wherein the guide rail has a proportion of at least 95 wt. % metal.

12. Battery shell according to claim 1 , wherein the guide rail has a proportion of at least 98 wt. % metal.

13. Battery shell according to claim 1 , wherein the guide rail has a proportion of at least 95 wt. % plastics material.

14. Battery shell according to claim 1 , wherein the guide rail has a proportion of at least 98 wt. % plastics material.

15. Battery shell according to claim 1 , wherein the inner profile has a proportion of at least 95 wt. % of metal.

16. Battery shell according to claim 1 , wherein the inner profile has a proportion of at least 98 wt. % metal.

17. Battery shell according to claim 1 , wherein the fastening element fastens the component and wherein the fastening element comprises at least one of: a screw, a thread, a threaded insert, a nut, a washer, a threaded bolt, a weld nut, a weld bolt, a locking hook, a clip, a cable tie, a line holder, a cable holder, and a fir tree clip.

18. Battery shell according to claim 1 , wherein the battery shell is produced using a blow molding process.

19. Battery shell according to claim 1 , wherein the component is one of a plurality of components, all of which are fastened to the battery shell by the fastening system.
