Abstract

An interface system for mechanically decoupling a cooling system includes: a housing having an opening; an inset having opposite first and second sides; an interface body having first and second ends and a bore-hole open to the first and second ends thereof. The inset has a recess in the second side to accommodate the interface body. The interface body is at least partially inserted into the inset, and the inset is at least partially inserted into the opening in the housing such that the first side of the inset is inside the housing. The first side of the inset has an opening open to the bore-hole of the interface body. One end of the bore-hole is configured to slidably receive an inlet of a cooling pipe, and the other end of the bore-hole is configured to be connected, in a fluid-tight manner, with an external coolant supply or coolant discharge.

First claim

Whats is claimed is:

1. An interface system for mechanically decoupling an interface body and a cooling pipe of a cooling system for a battery cell or battery module of a vehicle, the interface system comprising:
a housing for a battery cell or a battery module, the housing comprising a part having an opening;
an inset having a first side and a second side opposite to the first side and being removably attached to the housing; and
an interface body having a first end, a second end, and a bore-hole with a first opening open to the first end and a second opening open to the second end,
wherein the inset has a recess in the second side to accommodate the interface body,
wherein the interface body is inserted into the inset such that the first end of the interface body is in the recess of the inset and the first end of the interface body is also inside the housing and surrounds an outer surface of an inlet of the cooling pipe,
wherein the inset is at least partially inserted into the part through the opening therein such that the first side of the inset is inside the housing,
wherein the first side of the inset has an opening open to the first opening of the bore-hole of the interface body,
wherein the inlet of the cooling pipe is arranged in the opening of the first side of the inset, and
wherein the first opening of the bore-hole through the interface body is configured to slidably receive the inlet of a cooling pipe, and the second opening of the bore-hole is configured to be connected, in a fluid-tight manner, with an external coolant supply or coolant discharge.

2. The interface system according to claim 1 , wherein the inset is inserted into the opening in the part of the housing, and
wherein the interface body is inserted into the inset and over the inlet.

3. The interface system according to claim 1 , wherein the inlet of the cooling pipe extends through the opening in the first side of the inset and is at least partially inserted, in a slidable manner, through the first end of the interface body into the first opening of the bore-hole of the interface body.

4. The interface system according to claim 3 , further comprising a first seal between an inner surface of the opening in the first side of the inset and an outer surface of the inlet.

5. The interface system according to claim 4 , further comprising a further seal between the inner surface of the first opening in the first end of the interface body and the outer surface of the inlet.

6. The interface system according to claim 5 , wherein the first seal and/or the further seal is an elastic seal.

7. The interface system according to claim 1 , wherein a drain channel is between the inset and the interface body.

8. The interface system according to claim 1 , wherein the inset and the housing are configured such when the inset is not fixed to the housing, the inset is moveable relative to the housing from the outside of the housing through the opening in the housing into the inside of the housing.

9. The interface system according to claim 1 , wherein the inset comprises a second seal abutting against an outer side of the housing when the inset is inserted into the opening in the part of the housing.

10. The interface system according to claim 1 , wherein the inset is configured to be fixed to the part of the housing.

11. The interface system according to claim 10 , wherein the inset comprises a first collar, and
wherein the first collar abuts against an outside wall of the part of the housing.

12. The interface system according to claim 1 , wherein the interface body is configured to be fixed to the inset.

13. The interface system according to claim 1 , wherein the interface body is configured to be fixed to the part of the housing.

14. The interface system according to claim 13 , wherein the inset comprises a first collar abutting against an outside wall of the part of the housing, and
wherein the interface body comprises a second collar abutting against an outside wall of the part of the housing and/or against the first collar of the inset.

15. The interface system according to claim 13 , wherein the inset comprises a second seal abutting against an outer side of the housing when the inset is inserted into the opening in the part of the housing, and
wherein the interface body and the inset are both configured to be fixed to the part of the housing by a plurality of fixing elements.

16. A battery system comprising the interface system according to claim 1 .

17. An interface system for mechanically decoupling an interface body and a cooling pipe of a cooling system for a battery cell or battery module of a vehicle, the interface system comprising:
a housing for a battery cell or a battery module, a cooling system, and a cooling pipe fluidly connected with the cooling system, the housing comprising a part having an opening;
an inset having a first side and a second side opposite to the first side and being removably attached to the housing; and
an interface body having a first end, a second end, and a bore-hole with a first opening open to the first end and a second opening open to the second end, the interface body being fixed to the part of the housing,
wherein the inset has a recess in the second side to accommodate the interface body,
wherein the interface body is at least partially inserted into the inset such that the first end of the interface body is in the recess of the inset,
wherein the inset is at least partially inserted into the part through the opening therein such that the first side of the inset is inside the housing,
wherein the first side of the inset has an opening open to the first opening of the bore-hole of the interface body,
wherein an inlet of the cooling pipe is slidably arranged through the opening in the first side of the inset, and
wherein the inlet of the cooling pipe is slidably arranged through the first opening of the bore-hole through the interface body, and the second opening of the bore-hole is configured to be connected, in a fluid-tight manner, with an external coolant supply or coolant discharge.
