Abstract

A device for transmitting an information item from a battery cell has a first transformer and a second transformer. The first transformer is arranged on an interior side of an outside shell of the battery cell. The first transformer is configured to emit a signal representing the information through the outside shell. The second transformer is arranged on an exterior side of the outside shell and is electrically isolated from the first transformer. The second transformer is configured to pick-up the signal in order to transmit the information from the battery cell.

Claims

1. A device for transmitting an information item from a battery cell, the device comprising:

a first transmitter arranged on an inner side of an outer shell of the battery cell, the first transmitter configured to emit a signal representing the information item through the outer shell; and

a second transmitter arranged on an outer side of the outer shell and galvanically isolated from the first transmitter, the second transmitter configured to pick up the signal.

2. The device as claimed in claim 1, wherein the second transmitter is configured to emit a further signal, representing a further information item, through the outer shell, and the first transmitter is configured to pick up the further signal.

3. The device as claimed in claim 1, wherein at least one of the first transmitter and the second transmitter is arranged directly on the outer shell.

4. The device as claimed in claim 1, wherein the first transmitter has a first transmission region directed to the outer shell and the second transmitter is arranged within the first transmission region.

5. The device as claimed in claim 1, wherein the first transmitter and the second transmitter are each formed as one of an inductive transmitter and a capacitive transmitter.

11. The device as claimed in claim 1, wherein the second transmitter has a second transmission region directed to the outer shell and the first transmitter is arranged within the second transmission region.

12. The device as claimed in claim 4, wherein the second transmitter has a second transmission region directed to the outer shell and the first transmitter is arranged within the second transmission region.

6. A battery cell for storing electrical energy, the battery cell comprising:

an outer shell configured to surround the battery cell; and

a device arranged on the outer shell, the device including;

a first transmitter arranged on an inner side of the outer shell, the first transmitter configured to emit a signal representing an information item through the outer shell; and

a second transmitter arranged on an outer side of the outer shell and galvanically isolated from the first transmitter, the second transmitter configured to pick up the signal.

7. The battery cell as claimed in claim 6, wherein:

the outer shell has a rupture membrane, and the device is arranged in a region of the rupture membrane.

8. The battery cell as claimed in claim 6, wherein the outer shell is electrically insulating in a region of the device.

9. The battery cell as claimed in claim 6, wherein the outer shell is electrically conductive in a region of the device.

10. A method for transmitting an information item from a battery cell, the method comprising:

emitting a signal representing the information item with a first transmitter arranged on an inner side of an outer shell of the battery cell, the signal configured to pass through the outer shell; and

picking up the signal with a second transmitter arranged on an outer side of the outer shell.
