Abstract

The disclosure relates to a battery carrier for at least one electric battery module in a vehicle, comprising: a hollow profile base configured to receive the electric battery module, wherein the hollow profile base has a plurality of hollow channels configured to allow fluid to pass through to control the temperature of the electric battery module; and a hollow profile side wall that laterally bounds the hollow profile base, wherein a fluid-distributing structure configured to distribute fluid to the hollow channels is formed in the hollow profile side wall, wherein the fluid-distributing structures configured to be fluidically connected to the plurality of hollow channels.

First claim

What is claimed is:

1. A battery carrier for at least one electric battery module in a vehicle, comprising:
a hollow profile base configured to receive the electric battery module, wherein the hollow profile base comprises a plurality of hollow channels configured to pass fluid to control a temperature of the electric battery module; and
a hollow profile side wall that laterally bounds the hollow profile base, wherein a fluid-distributing structure configured to distribute fluid to the hollow channels is formed in the hollow profile side wall, wherein the fluid-distributing structure is configured to be fluidically connected to the plurality of hollow channels;
wherein the hollow profile side wall comprises at least one web, and the hollow profile base is configured to be placed on the at least one web.

2. The battery carrier according to claim 1 , wherein the fluid-distributing structure extends in a longitudinal direction of the hollow profile side wall and is formed to guide the fluid in the longitudinal direction of the hollow profile side wall.

3. The battery carrier according to claim 1 , wherein the fluid-distributing structure comprises fluid openings that fluidically connect the fluid-distributing structure to the hollow channels of the hollow profile base.

4. The battery carrier according to claim 1 , wherein the fluid-distributing structure comprises a fluid hollow channel configured to guide the fluid, wherein the fluid hollow channel is formed in the hollow profile side wall and comprises fluid openings that fluidically connect the fluid-distributing structure to the hollow channels of the hollow profile base.

5. The battery carrier according to claim 1 , wherein the fluid-distributing structure is formed by a receiving recess that is formed in the longitudinal direction of the hollow profile side wall and is configured to receive a fluid-distributing tube.

6. The battery carrier according to claim 5 , wherein the fluid-distributing tube configured to guide the fluid is arranged in the receiving recess and is releasably connected to the hollow profile side wall.

7. The battery carrier according to claim 6 , wherein the fluid-distributing tube is releasably connected to the hollow profile side wall using a clip connection.

8. The battery carrier according to claim 5 , wherein the fluid-distributing tube comprises fluid openings that fluidically connect the fluid-distributing tube to the hollow channels of the hollow profile base.

9. The battery carrier according to claim 1 , wherein the fluid-distributing structure comprises two mutually opposite end sides, wherein the fluid-distributing structure is closed in a fluid-tight manner on a first end side and wherein the fluid-distributing structure comprises a fluid connection on a second end side.

10. The battery carrier according to claim 9 , wherein the fluid connection comprises a fluid nozzle.

11. The battery carrier according to claim 1 , wherein the fluid-distributing structure is closed in a fluid-tight manner on a first end side by a closing plate, wherein the closing plate is connected in a force-fitting manner to the fluid-distributing structure.

12. The battery carrier according to claim 1 , wherein the fluid-distributing structure faces the hollow profile base, and wherein the hollow profile side wall comprises a deformation region that faces away from the fluid-distributing structure and is configured to absorb impact energy using plastic deformation.

13. The battery carrier according to claim 12 , wherein the deformation region comprises a hollow chamber structure that extends along the hollow profile side wall and is configured to be plastically deformed.

14. The battery carrier according to claim 13 , wherein the hollow chamber structure comprises hollow chambers that lie one above another and are separated by a deformation web, wherein the deformation web is configured to be pushed into at least one of the hollow chambers during plastic deformation.

15. The battery carrier according to claim 12 , wherein the hollow profile side wall comprises a vertical wall extending in a vertical direction of the battery carrier, and wherein the deformation region extends at an angle from the vertical wall and faces away from the hollow profile base.

16. The battery carrier according to claim 15 , wherein the angle comprises a right angle.

17. The battery carrier according to claim 14 , wherein the hollow profile base is connected to the at least one web mechanically.

18. The battery carrier according to claim 17 , wherein the hollow profile base is connected to the at least one web in a force-fitting or integrally bonded manner.
