Abstract

Device to monitor the voltage of battery cells. The device includes a control device, voltage taps configured to tap the voltages of the battery cells, a holding plate having a first holding plate part and a second holding plate part, and a stamped-out circuit having measuring lines configured to electrically connect the control device to the voltage taps, the stamped-out circuit being arranged in cut-outs of the first holding plate part and the cut-outs being covered by the second holding plate such that the measuring lines are fixedly positioned in the cut-outs.

First claim

What is claimed is:

1. A device to monitor battery cell voltages, the device comprising:
a control device configured to monitor battery cells;
voltage taps configured to tap voltages of the battery cells;
a holding plate comprising first and second holding plates, the first holding plate having a plurality of cut-outs therein; and
a stamped-out circuit comprising measuring lines configured to electrically connect the control device to the voltage taps, ones of the measuring lines being arranged in respective ones of the cut-outs in the first holding plate that correspond to the shape of the measuring lines,
wherein control device-side ends of the measuring lines extend out of the cut-outs at ends of the cut-outs in a direction perpendicular to a surface of the first holding plate to be at a height of the second holding plate, the ends of the ones of the cut-outs being spaced from the respective ones of the voltage taps in a direction parallel to the surface of the first holding plate, and
wherein the second holding plate covers the cut-outs in the first holding plate such that the measuring lines are contained in the cut-outs.

2. The device of claim 1 , wherein the voltage taps are arranged in the cut-outs of the first holding plate.

3. The device of claim 2 , further comprising holding elements configured to hold the voltage taps in the cut-outs of the first holding plate.

4. The device of claim 3 , wherein the holding elements comprise elastic holding elements.

5. The device of claim 1 , wherein the voltage taps are at least partially covered by the second holding plate.

6. The device of claim 1 , wherein the second holding plate comprises maintenance orifices in a region of the voltage taps.

7. The device of claim 1 , wherein the control device is structurally integrated in the holding plate.

8. The device of claim 7 , wherein the control device is arranged on the first holding plate.

9. The device of claim 1 , wherein the second holding plate comprises a control device orifice in a region of the control device.

10. The device of claim 1 , further comprising a plug-connector configured to directly connect the control device to the measuring lines.

11. The device of claim 10 , wherein the control device is directly connected to the measuring lines at the control device-side ends of the measuring lines.

12. The device of claim 1 , wherein the control device-side ends of the measuring lines comprise male connectors configured to connect to corresponding female connectors of the control device.

13. The device of claim 1 , wherein the second holding plate comprises a stop adjacent the control device, the stop being configured to block a horizontal displacement of the measuring lines.

14. A battery module comprising:
a plurality of battery cells, each of the battery cells comprising connection terminals;
a control device configured to monitor voltages of the battery cells;
voltage taps electrically connected to the connection terminals to tap the voltages of the battery cells;
a first holding plate and a second holding plate, the first holding plate having a plurality of cut-outs therein; and
a stamped-out circuit comprising measuring lines configured to electrically connect the control device to the voltage taps, ones of the measuring lines being arranged in respective ones of the cut-outs in the first holding plate and extending along a direction parallel to a surface of the first holding plate,
wherein the cut-outs are covered by the second holding plate such that the measuring lines are contained in the cut-outs, and
wherein control device-side ends of the measuring lines extend out of the cut-outs in a direction perpendicular to the surface of the first holding plate to be at a height of the second holding plate at an end of each of the cut-outs, the end of each of the cut-outs being spaced from the respective voltage tap in the direction parallel to the surface of the first holding plate.

15. The battery module of claim 14 , wherein the voltage taps are arranged in the cut-outs of the first holding plate.

16. The battery module of claim 15 , further comprising holding elements configured to hold the voltage taps in the cut-outs in the first holding plate.

17. The battery module of claim 14 , further comprising a plug-connector configured to directly connect the control device to the measuring lines.

18. The battery module of claim 14 , wherein the control device-side ends of the measuring lines comprise male connectors configured to connect to corresponding female connectors of the control device.

19. The battery module of claim 14 , wherein the second holding plate comprises a stop adjacent the control device, the stop being configured to block a horizontal displacement of the measuring lines.
