Abstract

The device according to the invention for storing electrical energy comprises at least one galvanic cell. The same is at least partially surrounded by a casing. Furthermore, the device comprises a cell holding unit comprising an internal space. The at least one galvanic cell is arranged in the internal space. Furthermore, the cell holding unit comprises a wall, which at least partially delimits said internal space. Therein, the wall of the cell holding unit and/or the at least one galvanic cell comprise at least one hollow space. The at least one hollow space is at least partially filled with a first heat conducting means.

Claims

1. A device for storing of electrical energy comprising at least one galvanic cell, which is at least partially surrounded by a casing;

and

a cell holding unit having an internal space and a casing, which at least partially delimits the internal space,

wherein the at least one galvanic cell is arranged inside the internal space, and wherein at least one of the casing and the at least one galvanic cell include at least one hollow space

wherein the at least one hollow space is at least partially filled with one first heat conducting means.

2. Device The device according to claim 1, further comprising at least one second heat conducting means is at least partly arranged between the casing and the galvanic cell.

3. Device The device according to claim 1, wherein the first heat conducting means is capable of at least partially undergoing a phase change and that the phase change occurs at predetermined conditions, which are adapted to the operating conditions of the at least one galvanic cell.

4. The device according to claim 1, wherein the first heat conducting means is at least partially capable of flowing and that the at least one hollow space is configured to guide the first heat conducting means.

5. The device according to claim 4, wherein the device is associated with at least one container, which is connected with the at least one hollow space.

6. The device according to claim 1, wherein the device is assigned to a delivery unit, which is provided to deliver the first heat conducting means.

7. The device according to claim 1, further comprising a heat exchanger, which is provided to exchange heat energy between the first heat conducting means and a heat sink.

8. The device according to claim 1, wherein the device is assigned to at least a first measuring unit, a control unit and an operating unit, wherein the control unit is provided to operate the operating unit.

9. The device according to claim 8, wherein the device is assigned to a second measuring unit, which preferably records a pressure or pressure differences.

10. The device according to claim 1, wherein the control unit is capable of exchanging signals with a higher level control.

11. The device according to claim 8, further comprising a measuring unit measuring value, wherein the control unit, depending on a deviation of the measuring value from a predefined target value, operates at least one of an operating unit and a delivery unit.

12. The device according to claim 11, wherein the control unit, depending on a deviation of the measuring value from a predefined target value, sends a predefined signal to a higher level control.
