Abstract

An energy store includes a housing and bridge plug. In relation to the housing, the bridge plug is receivable by the housing in two orientations different from each other, e.g., in the same opening or configuration of openings.

First claim

What is claimed is:

1. An energy store, comprising:
a housing; and
a bridge plug;
wherein the housing and the bridge plug are configured such that the bridge plug is insertable into the housing in two orientations that are different from each other;
wherein a cutout is arranged in the bridge plug and electrically connects two terminals; and
wherein in a first orientation of the bridge plug, a current path of the energy store leads through the cutout and a current path connects a potential of an energy storage module of the energy store to a terminal for a potential of the energy store, and, in a second orientation of the bridge plug, the current path is cut off.

2. The energy store according to claim 1 , wherein the housing and the bridge plug are configured such that the bridge plug is insertable into the housing in two orientations that are different from each other in a same opening and/or configuration of openings.

3. The energy store according to claim 1 , wherein the housing includes a cover part, and the bridge plug includes an upper part and a lower part connected to the upper part, the upper part being connected to the cover part, the lower part being arranged between the upper part and the cover part.

4. An energy store, comprising:
a housing; and
a bridge plug;
wherein the housing and the bridge plug are configured such that the bridge plug is receivable by the housing in two orientations that are different from each other;
wherein the housing includes a cover part, and the bridge plug includes an upper part and a lower part connected to the upper part, the upper part being connected to the cover part, the lower part being arranged between the upper part and the cover part; and
wherein the lower part is screw connected to the upper part, and the upper part is screw connected to the cover part by screws that are received in tapped holes of the cover part and that include screw heads that push the upper part toward the cover part.

5. An energy store, comprising:
a housing; and
a bridge plug;
wherein the housing and the bridge plug are configured such that the bridge plug is receivable by the housing in two orientations that are different from each other;
wherein the housing includes a cover part, and the bridge plug includes an upper part and a lower part connected to the upper part, the upper part being connected to the cover part, the lower part being arranged between the upper part and the cover part; and
wherein regions projecting toward an interior of the energy store surrounded by the housing are formed on the lower part, each region protruding at least partially through an opening that passes through the cover part, the regions being set apart from each other, the openings being set apart from each other.

6. The energy store according to claim 5 , wherein a cutout is arranged in the bridge plug and electrically connects two terminals.

7. The energy store according to claim 1 , wherein a first terminal of the two terminals is detachably electrically connected electrically to a first contact pin accommodated in a lower part of the bridge plug, and a second terminal of the two terminals is detachably electrically connected electrically to a second contact pin accommodated in the lower part.

8. The energy store according to claim 1 , wherein a first region of the lower part surrounds a first contact pin at least partially, and a second region of the lower part surrounds a second contact pin at least partially.

9. An energy store, comprising:
a housing; and
a bridge plug;
wherein the housing and the bridge plug are configured such that the bridge plug is receivable by the housing in two orientations that are different from each other;
wherein a circuit board piece is accommodated in the lower part, the circuit board piece includes circuit traces arranged on a first side of the circuit board piece electrically connected electrically to circuit traces arranged on a second side of the circuit board piece via plated-through holes.

10. The energy store according to claim 9 , wherein a third region of the lower part surrounds the circuit board piece at least partially.

11. The energy store according to claim 6 , wherein in a first orientation of the bridge plug, a current path of the energy store leads through the cutout and a current path connects a potential of an energy storage module of the energy store to a terminal for a potential of the energy store, and, in a second orientation of the bridge plug, the current path is cut off.

12. An energy store, comprising:
a housing; and
a bridge plug;
wherein the housing and the bridge plug are configured such that the bridge plug is insertable into the housing in two orientations that are different from each other;
wherein in a first orientation of the bridge plug, via a circuit board piece, signal lines connect signal electronics of the energy store to energy storage devices of the energy store, and, in a second orientation of the bridge plug, the signal lines are cut off.

13. The energy store according to claim 12 , wherein the energy storage device includes (a) an accumulator and (b) double-layer capacitors and/or ultracaps.

14. The energy store according to claim 9 , wherein in a first orientation of the bridge plug, the circuit board piece is received and/or inserted in a connecting part.

15. An energy store, comprising:
a housing; and
a bridge plug;
wherein the housing and the bridge plug are configured such that the bridge plug is insertable into the housing in two orientations that are different from each other;
wherein a cutout is arranged in the bridge plug and electrically connects two terminals,
wherein a first terminal of the two terminals is detachably electrically connected electrically to a first contact pin accommodated in a lower part of the bridge plug, and a second terminal of the two terminals is detachably electrically connected electrically to a second contact pin accommodated in the lower par; and
wherein in a first orientation, the first contact pin is received in a first socket part, the second contact pin is received in a second socket part, and the first socket part, the second socket part, and a connecting part are provided on a circuit board of signal electronics of the energy store.

16. The energy store according to claim 15 , wherein in a second orientation, the first contact pin is received in the first socket part, and the second contact pin is set apart from the circuit board of the signal electronics and not connected to the first socket part provided on the circuit board.

17. The energy store according to claim 15 , wherein the first and the second socket parts formed of metal.

18. The energy store according to claim 1 , wherein the bridge plug includes an indication device.

19. The energy store according to claim 15 , wherein signal lines of the signal electronics are fed through controllable semiconductor switches that are closed in response to application of a deblocking signal to an input of the energy store and that are open in response to non-application of a deblocking signal to an input of the energy store.

20. An energy store, comprising:
a housing; and
a bridge plug insertable into the housing in two orientations different from each other in a same opening or configuration of openings, the bridge plug including a cutout electrically connecting two terminals;
wherein in a first one of the orientations of the bridge plug, a current path of the energy store leads through the cutout, and i
