Abstract

A battery device having at least one battery and having at least one heating and/or cooling device temperature-controlling the battery. It is provided that the battery, submerged in an heating and/or cooling medium, is situated in a housing that accommodates the heating and/or cooling medium. The present invention also relates to a corresponding method.

Claims

1-10. -10. (canceled)

11. A battery device comprising:

at least one battery and at least one of a heating device and a cooling device temperature-controlling the battery, wherein the battery is submerged in a heating or cooling medium and is situated in a housing that accommodates said heating or cooling medium.

12. The battery device as recited in claim 11, wherein the heating or cooling medium is conveyed in a circulatory system, and at least one of a heating device and a cooling device for the heating or cooling medium is located in the circulatory system.

13. The battery device as recited in claim 11, wherein the battery is enveloped by a hermetically sealed enclosure on all sides.

14. The battery device as recited in claim 12, wherein the battery is enveloped by a hermetically sealed enclosure on all sides.

15. The battery device as recited in claim 13, wherein the enclosure is a foil.

16. The battery device as recited in claim 14, wherein the enclosure is a foil.

17. The battery device as recited in claim 13, wherein the inside of the enclosure is evacuated.

18. The battery device as recited in claim 14, wherein the inside of the enclosure is evacuated.

19. The battery device as recited in claim 11, wherein the battery has encapsulated or bonded contact locations or terminal locations for insulation from the heating or cooling medium.

20. The battery device as recited in claim 12, wherein the battery has encapsulated or bonded contact locations or terminal locations for insulation from the heating or cooling medium.

21. The battery device as recited in claim 13, wherein the battery has encapsulated or bonded contact locations or terminal locations for insulation from the heating or cooling medium.

22. The battery device as recited in claim 15, wherein the battery has encapsulated or bonded contact locations or terminal locations for insulation from the heating or cooling medium.

23. The battery device as recited in claim 17, wherein the battery has encapsulated or bonded contact locations or terminal locations for insulation from the heating or cooling medium.

24. The battery device as recited in claim 11, wherein the heating or cooling medium is an incombustible medium.

25. The battery device as recited in claim 12, wherein the heating or cooling medium is an incombustible medium.

26. The battery device as recited in claim 11, wherein the heating or cooling medium is an electrically nonconductive medium.

27. The battery device as recited in claim 12, wherein the heating or cooling medium is an electrically nonconductive medium.

28. The battery device as recited in claim 11, wherein the heating or cooling medium is a fireproofing agent or contains a fireproofing agent.

29. A method for temperature-controlling a battery device as recited in claim 11.
