Abstract

The invention relates to a cooling plate (10) for battery cells (40), wherein the cooling plate (10) is in the form of a mounting plate and has mounting elements (12) for directly mounting the cooling plate (10) into a motor vehicle. It is further necessary for the cooling plate (10) together with a housing (20), in particular a half-shell housing, to form a closed-off space (30) for accommodating battery cells (40). The invention further relates to battery cells (40), to a battery cell module and also to a motor vehicle having a battery cell module of this kind.

First claim

The invention claimed is:

1. A battery cell module comprising:
a cooling plate ( 10 ) for battery cells ( 40 ), wherein the cooling plate ( 10 ) is in the form of a mounting plate and has mounting elements ( 12 ) configured for directly mounting the cooling plate ( 10 ) into a motor vehicle,
characterized in that the cooling plate ( 10 ), together with a first housing ( 20 ), forms a first closed-off space ( 30 ) for accommodating battery cells ( 40 ),
wherein the cooling plate ( 10 ), together with a second housing ( 20 ), forms a second closed-off space ( 30 ) for accommodating battery cells ( 40 ),
wherein the second closed-off space ( 30 ) is separated from the first closed-off space;
wherein the first housing ( 20 ) includes an outer periphery;
wherein the cooling plate ( 10 ) includes an outer periphery; and
wherein the entire outer periphery of the cooling plate ( 10 ) is outside of the outer periphery of the first housing ( 20 ).

2. The battery cell module as claimed in claim 1 , characterized in that the mounting elements ( 12 ) are in the form of openings.

3. The battery cell module as claimed in claim 1 , characterized in that the mounting elements ( 12 ) are in the form of fastening or holding elements.

4. The battery cell module as claimed in claim 1 , characterized in that the cooling plate ( 10 ) forms a lower boundary of one of the closed-off spaces ( 30 ).

5. The battery cell module as claimed in claim 1 , characterized in that the cooling plate ( 10 ) forms an upper boundary of one of the closed-off spaces ( 30 ).

6. The battery cell module as claimed in claim 1 , characterized in that the first closed-off space ( 30 ) is sealed off by means of a seal ( 15 ) which is arranged between the first housing ( 20 ) and the cooling plate ( 10 ).

7. The battery cell module as claimed in claim 1 , characterized in that the cooling plate ( 10 ) comprises cooling lines ( 14 ).

8. The battery cell module as claimed in claim 7 , characterized in that the cooling lines ( 14 ) are arranged in the interior of the cooling plate ( 10 ).

9. The battery cell module as claimed in claim 7 , characterized in that the cooling lines ( 14 ) comprise an inlet opening ( 16 ) and an outlet opening ( 17 ).

10. The battery cell module as claimed in claim 1 , wherein the housing is a half-shell housing.

11. A battery cell module having a plurality of battery cells ( 40 ) electrically connected to one another, the battery cell module comprising
a cooling plate ( 10 ) in the form of a mounting plate, the cooling plate having mounting elements ( 12 ) configured for directly mounting the cooling plate ( 10 ) into a motor vehicle,
a first housing ( 20 ) which, together with the cooling plate, forms a first closed-off space ( 30 ),
a second housing ( 20 ) which, together with the cooling plate, forms a second closed-off space ( 30 ), separate from the first closed-off space ( 30 ), and
battery cells ( 40 ) arranged in the first and second closed-off spaces ( 30 ) formed by the first and second housings ( 20 ) and the cooling plate ( 10 ),
wherein the first housing ( 20 ) includes an outer periphery;
wherein the cooling plate ( 10 ) includes an outer periphery; and
wherein the entire outer periphery of the cooling plate ( 10 ) is outside of the outer periphery of the first housing ( 20 ).

12. The battery cell module as claimed in claim 11 , characterized in that the battery cells ( 40 ) are arranged directly on the cooling plate ( 10 ).

13. The battery cell module as claimed in claim 11 , characterized in that the battery cells ( 40 ) are arranged in a manner suspended directly from the cooling plate ( 10 ).

14. A motor vehicle, comprising a battery cell module as claimed in claim 11 , wherein the battery cell module is connected to a drive system of the motor vehicle and is mounted in the motor vehicle by means of the cooling plate ( 10 ).

15. The battery cell module as claimed in claim 11 , characterized in that the mounting elements ( 12 ) are in the form of openings.

16. The battery cell module as claimed in claim 11 , characterized in that the mounting elements ( 12 ) are in the form of fastening or holding elements.

17. The battery cell module as claimed in claim 11 , characterized in that the cooling plate ( 10 ) forms a lower boundary of the first closed-off space ( 30 ).

18. The battery cell module as claimed in claim 11 , characterized in that the cooling plate ( 10 ) forms an upper boundary of the second closed-off space ( 30 ).

19. The battery cell module as claimed in claim 11 , characterized in that the first closed-off space ( 30 ) is sealed off by means of a seal ( 15 ) which is arranged between the first housing ( 20 ) and the cooling plate ( 10 ).

20. The battery cell module as claimed in claim 11 , characterized in that the cooling plate ( 10 ) comprises cooling lines ( 14 ).

21. The battery cell module as claimed in claim 20 , characterized in that the cooling lines ( 14 ) are arranged in the interior of the cooling plate ( 10 ).
