Abstract

A cooling system for cooling electrochemical cells of a battery system is provided. The cooling system includes a housing configured to accommodate a plurality of stacked electrochemical cells. The housing includes a structured side wall having a protrusion therein, and the protrusion is adapted to receive a section of a thermally conductive element arranged between two adjacent ones of the stacked electrochemical cells.

First claim

What is claimed is:

1 . A cooling system for cooling electrochemical cells of a battery system, the cooling system comprising a housing configured to accommodate a plurality of stacked electrochemical cells, the housing comprising a structured side wall having a protrusion therein, the protrusion being adapted to receive a section of a thermally conductive element arranged between two adjacent ones of the stacked electrochemical cells.

2 . The cooling system of claim 1 , wherein the housing further comprises first side walls extending parallel to a height of the electrochemical cells accommodated by the housing and second side walls arranged perpendicular to the first side walls, and
wherein the structured side wall is one of the second side walls.

3 . The cooling system of claim 1 , wherein the structured side wall has a plurality of the protrusions therein that are respectively configured to receive the thermally conductive elements, and
wherein the structured side wall comprising the protrusions has a meandering cross-section.

4 . The cooling system of claim 1 , wherein the protrusion in the structured side wall has a U-shaped cross-section.

5 . The cooling system of claim 1 , wherein the protrusion is a groove in the structured side wall.

6 . The cooling system of claim 1 , wherein the housing comprises a plastic material.

7 . The cooling system of claim 1 , wherein the structured side wall has a plurality of the protrusions therein that are respectively configured to accommodate the thermally conductive elements, and
wherein a space between adjacent ones of the protrusions on an outer side of the structured side wall forms an outer receiving structure configured to receive a cooling fin.

8 . The cooling system of claim 7 , further comprising a holding device configured to receive the housing, the holding device comprising the cooling fin corresponding to the outer receiving structure of the structured side wall.

9 . The cooling system of claim 8 , wherein the holding device has a body section from which the cooling fin extends.

10 . The cooling system of claim 9 , wherein the holding device has a channel in the body section thereof, the channel being configured to allow a cooling fluid to flow through the body section.

11 . The cooling system of claim 8 , wherein the cooling fin comprises a thermally conductive material.

12 . A battery system comprising:
a plurality of stacked electrochemical cells; a thermally conductive element arranged between adjacent ones of the stacked electrochemical cells; and a housing accommodating the stacked electrochemical cells, the housing comprising a structured side wall having a protrusion therein, wherein a section of the thermally conductive element is arranged within the protrusion in the structured side wall.

13 . The battery system of claim 12 , wherein the thermally conductive element has a plate shape and a height that is greater than a height of the electrochemical cells.

14 . The battery system of claim 12 , wherein the section of the thermally conductive element is received in the protrusion in the structured side wall via a form-fit connection.

15 . The battery system of claim 12 , wherein, in a fully assembled state, the section of the thermally conductive element received by the protrusion does not extend along an entire depth of the protrusion.
