Abstract

The present invention relates to a cell contacting arrangement for an energy storage module having a plurality of electrochemical storage cells, each storage cell having at least two electric connection terminals, the arrangement comprising: a carrier plate which is mountable on the energy storage module, and at least one cell connector inserted into the carrier plate for connecting at least two of the connection terminals of different storage cells, the carrier plate comprising at least one catch spring having a detent for fixing the cell connector in the carrier plate.

First claim

The invention claimed is:

1. A cell contacting arrangement for an energy storage module having a plurality of electrochemical storage cells, each storage cell having at least two electric connection terminals, the arrangement comprising:
a carrier plate which is mountable on the energy storage module,
at least one cell connector inserted into the carrier plate for connecting at least two of the connection terminals of different storage cells,
the carrier plate comprising at least one catch spring having a detent for fixing the cell connector in the carrier plate, and
wherein the catch spring is configured to be arcuate, a first end of the arc being connected to the carrier plate, and the detent being arranged on the second end of the arc.

2. The cell contacting arrangement according to claim 1 , wherein the catch spring and the detent are integrally produced with the carrier plate.

3. The cell contacting arrangement according to claim 1 , wherein a catch spring with a detent is provided per connection terminal contacted by the cell connector.

4. The cell contacting arrangement according to claim 1 , wherein the cell connector at the side opposite to the catch spring is pushed under a shoulder of the carrier plate.

5. The cell contacting arrangement according to claim 1 , wherein the cell connector comprises connection surfaces which are configured for connection with the connection terminals.

6. The cell contacting arrangement according to claim 1 , wherein the cell connector comprises connection surfaces which are configured for connection with the connection terminals, and the detent blocks a movement of the cell connector in a first direction, and that the catch spring allows a spring-loaded movement of the cell connector in a second direction perpendicular to the first direction.

7. The cell contacting arrangement according to claim 6 , wherein the cell connector comprises connection surfaces which are configured for connection with the connection terminals, and the connection surface is configured as a plate, the second direction extending perpendicular to the direction of the thickness of the plate.

8. The cell contacting arrangement according to claim 6 , wherein the cell connector comprises connection surfaces which are configured for connection with the connection thermals, and the connection surfaces of the cell connector for the connection terminals to be connected are arranged one after the other in a third direction, the third direction being perpendicular to the second direction.

9. The cell contacting arrangement according to claim 1 , wherein the cell connector between two connection surfaces comprises a connection arc for compensating for internal stresses in the cell connector.

10. A high-voltage storage device for power supply, particularly of an automotive vehicle, comprising:
an energy storage module having a plurality of electrochemical storage cells, each storage cell having at least two electric connection terminals , and
a cell contacting arrangement according to claim 1 .

11. A cell contacting arrangement for an energy storage module having a plurality of electrochemical storage cells, each storage cell having at least two electric connection terminals, the arrangement comprising:
a carrier plate which is mountable on the energy storage module,
at least one cell connector inserted into the carrier plate for connecting at least two of the connection terminals of different storage cells,
the carrier plate comprising at least one catch spring having a detent for fixing the cell connector in the carrier plate,
wherein the catch spring is configured to be arcuate, a first end of the arc being connected to the carrier plate, and the detent being arranged on the second end of the arc, and
wherein the cell connector comprises connection surfaces which are configured for connection with the connection terminals, and the detent blocks a movement of the cell connector in a first direction, and that the catch spring allows a spring-loaded movement of the cell connector in a second direction perpendicular to the first direction.

12. The cell contacting arrangement according to claim 11 , wherein the catch spring and the detent are integrally produced with the carrier plate.

13. The cell contacting arrangement according to claim 11 , wherein a catch spring with a detent is provided per connection terminal contacted by the cell connector.

14. The cell contacting arrangement according to claim 11 , wherein the cell connector at the side opposite to the catch spring is pushed under a shoulder of the carrier plate.

15. The cell contacting arrangement according to claim 11 , wherein the cell connector comprises connection surfaces which are configured for connection with the connection terminals, and the connection surface is configured as a plate, the second direction extending perpendicular to the direction of the thickness of the plate.

16. The cell contacting arrangement according to claim 11 , wherein the cell connector comprises connection surfaces which are configured for connection with the connection thermals, and the connection surfaces of the cell connector for the connection terminals to be connected are arranged one after the other in a third direction, the third direction being perpendicular to the second direction.

17. The cell contacting arrangement according to claim 11 , wherein the cell connector between two connection surfaces comprises a connection arc for compensating for internal stresses in the cell connector.

18. A high-voltage storage device for power supply, particularly of an automotive vehicle, comprising:
an energy storage module having a plurality of electrochemical storage cells, each storage cell having at least two electric connection terminals, and
a cell contacting arrangement according to claim 11 .
