Claims

1.-10. (canceled)

11. A holding device for battery cells for a high-voltage storage device module which is usable in electrically operated motor vehicles, the holding device comprising: an insulating plate provided with a recess pattern for each battery cell, wherein the recess pattern comprises positioning supports for the battery cell and flow grooves for introduction of an adhesive.

12. The holding device according to claim 11, wherein the positioning supports are configured such that contact between the battery cell and a cooling plate is prevented.

13. The holding device according to claim 12, wherein the flow grooves are configured to ensure that a cavity between the battery cells, which lie on a positioning support, and the cooling plate is completely filled with the adhesive.

14. The holding device according to claim 11, wherein the flow grooves are formed as evenly distributed knob-shaped recesses.

15. The holding device according to claim 11, wherein the positioning supports are formed in the insulating plate as evenly distributed depressions in a form of spacers.

16. The holding device according to claim 11, wherein a number of the flow grooves is a multiple of a number of the positioning supports.

17. The holding device according to claim 11, wherein the positioning supports and the flow grooves are arranged alternately in the recess pattern in equal numbers.

18. The holding device according to claim 11, wherein each positioning support is directly adjacent to one of the flow grooves.

19. The holding device according to claim 11, wherein the adhesive is introduced via the flow grooves with an excess which contributes to lateral support.

20. A vehicle comprising a high-voltage storage device, which comprises the holding device according to claim 11.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] FIG. 1 shows a plan view of the overall arrangement according to an embodiment of the invention, holding a battery cell.

[0013] FIG. 2 shows a cross-section of FIG. 1 through the vertical axis (z axis) with a 120° angle (section A-A).

[0014] FIG. 3 shows a plan view of the recess pattern according to an embodiment of the invention in the insulating plate, without a battery cell.

DETAILED DESCRIPTION OF THE DRAWINGS

[0015] FIG. 1 shows a battery cell 1 in an insulating plate 3 (detail) provided with a recess pattern. In FIG. 1, seen from above, only the flow grooves 4 for the introduction of an adhesive 6 (FIG. 2) can be seen.

[0016] FIG. 2 shows FIG. 1 as seen in the section A-A. The battery cell 1 is seated on a positioning support 5 of the insulating mat 3 and is therefore spaced from a cooling plate 2 provided below the insulating mat 3. The positioning supports 5 are therefore configured in such a way that contact between the battery cell 1 and the cooling plate 2 is prevented.

[0017] In FIG. 2, a flow groove 4 can moreover be seen, which is configured so as to ensure that the cavity between the battery cells 1, which lie on the positioning support 5, and the cooling plate 2 is completely filled with adhesive 6. The chosen adhesive should be electrically insulating.

[0018] FIG. 3 shows all positioning supports 5 (3 here, in the case of a round cell form) and all flow grooves 4 (6 here, in the case of a round cell form).

[0019] The flow grooves 4 are formed as evenly distributed knob-shaped recesses, so that it is possible for the adhesive 6 to escape in a laterally supporting manner.

[0020] The positioning supports 5 are (integrally) formed in the insulating plate 3 as uniformly distributed depressions in the form of spacers.

[0021] The number of flow grooves 4 here is double the number of positioning supports 5. Each positioning support 5 may be directly adjacent to every second flow groove 4.
