Abstract

The invention is based on a device having at least one electrochemical cell (10), which is embodied as essentially flat and has laterally protruding cooling lugs (20, 22) for electrical contacting.

It is proposed that each cell (10) is enclosed between two housing parts (30, 40) that clamp the cell (10) between them with pressure force in at least some regions.

Claims

1. A device having at least one electrochemical cell (10), which is embodied as essentially flat and has laterally protruding cooling lugs (20, 22) for electrical contacting, characterized in that each cell (10) is enclosed between two housing parts (30, 40) that clamp the cell (10) between them with pressure force in at least some regions.

2. The device as defined by claim 1, characterized in that the cell (10) is subjected to pressure force on its edge.

3. The device as defined by claim 1, characterized in that the cooling lugs (20, 22) are subjected to pressure force.

4. The device as defined by claim 1, characterized in that at least one housing part (30, 40) has an indentation (36, 46) for receiving the cell (10).

5. The device as defined by claim 1, characterized in that an encompassing edge (32, 42, 42a) is provided, which subjects the cell (10) to pressure force on its edge.

6. The device as defined by claim 5, characterized in that one housing part (30) has a bead, and the other housing part (40) has a complementary groove.

7. The device as defined by claim 1, characterized in that a shoulder (38, 48) is provided, which subjects a cooling lug (20, 22) to pressure force.

8. The device as defined by claim 1, characterized in that in at least one housing part (30, 40), openings (34a, 44a) for a cooling medium are provided.

9. The device as defined by claim 1, characterized in that in at least one housing part (30, 40), conduits for a cooling medium are provided.

10. The device as defined by claim 1, characterized in that a plurality of encased cells (100) are stacked on one another in a stacking direction (56) and braced against one another.

11. The device as defined by claim 1, characterized in that the cooling lugs (20, 22) protrude from the housing parts (30, 40) and are connected electrically to one another in series and/or parallel.

12. The device as defined by claim 11, characterized in that when there is a plurality of encased cells (100), the cooling lugs (20, 22) on both sides of the housing parts (30, 40) are each clamped in a clamping device (66, 68) for clamping and electrical contacting of the cooling lugs (20, 22) and, except for one cooling lug (20a, 22a) of each of the outer cells (10), at least two cooling lugs (20, 22) on the same side are joined together in the clamping device (66, 68).
