Abstract

A battery holder for an electric vehicle is disclosed. The battery holder is mounted in a subfloor region of the electric vehicle and includes a pan and a cover. The pan is formed by an outer encircling frame and a bottom. A cooling system is integrated in the bottom of the pan.

First claim

The invention claimed is:

1. A battery holder for an electric vehicle, comprising:
a pan;
a cover;
wherein the pan is formed by an outer encircling frame and a double-layered bottom; and,
a cooling system integrated in the bottom of the pan, and wherein the cooling system is formed by the bottom layers.

2. The battery holder according to claim 1 , wherein the frame is formed from a hollow profile.

3. The battery holder according to claim 1 , wherein cooling ducts are formed between the two bottom layers to carry a heat transfer fluid.

4. The battery holder according to claim 1 , wherein the cooling system can operate as a heating system by reversal of the heat flux.

5. The battery holder according to claim 1 , wherein latent heat storages are arranged in the bottom.

6. The battery holder according to claim 5 , wherein the latent heat storages are arranged between the cooling ducts.

7. The battery holder according to claim 1 , wherein at least one bottom layer is formed from a metallic material, preferably the two bottom layers are formed from a metallic material.

8. The battery holder according to claim 1 , wherein at least one bottom layer is formed from a fiber composite and/or a plastic material.

9. The battery holder according to claim 1 , wherein the first bottom layer facing the batteries is made from a light metal.

10. The battery holder according to claim 1 , wherein at least one battery lies in sheetlike manner with a bias force against the bottom.

11. The battery holder according to claim 1 , the bottom layers are coupled to each other in integrally bonded and/or form-fitting manner.

12. The battery holder according to claim 1 , wherein the battery holder is mounted in a subfloor region of an electric vehicle.

13. The battery holder according to claim 2 , wherein the hollow profile is a multichambered hollow profile.

14. The battery holder according to claim 2 , further comprising at least one transverse web and at least one longitudinal web are arranged in the frame.

15. The battery holder according to claim 9 , wherein the light metal is an aluminum alloy.

16. The battery holder according to claim 11 , wherein the coupled comprises being joined together by adhesive and/or screws.
