Abstract

The invention is based on a rechargeable battery charging case, in particular a cordless handheld power tool case, having at least one battery attachment device and a case body. It is proposed that the rechargeable battery charging case has an electrical energy output and a supply unit, which in at least one operating state is connected to the energy output and to the battery attachment device for supplying the energy output.

Claims

1. A rechargeable battery charging case, in particular a cordless handheld power tool case, having at least one battery attachment device and a case body, and having an electrical energy output and a supply unit, which in at least one operating state is connected to the energy output and to the battery attachment device for supplying the energy output.

2. The rechargeable battery charging case as defined by claim 1, wherein the battery attachment device has at least one coupling means, which is provided for connecting at least one battery charger of the battery attachment device disconnectably mechanically and disconnectably electrically to the case body.

3. The rechargeable battery charging case as defined by claim 1, further having a case body, wherein the case body has a suspension device, with an energy input and/or an energy output.

4. The rechargeable battery charging case as defined by claim 2, further having a case body, wherein the case body has a suspension device, with an energy input and/or an energy output.

5. The rechargeable battery charging case as defined by claim 1, wherein the case body has at least one BUS system, which is provided for connecting a plurality of units at least electrically.

6. The rechargeable battery charging case as defined by claim 1, further having a battery charger, which is provided for charging a rechargeable battery separately from the case body.

7. The rechargeable battery charging case as defined by claim 2, further having a battery charger, which is provided for charging a rechargeable battery separately from the case body.

8. The rechargeable battery charging case as defined by claim 1, further having a battery charger, which has at least one coupling device that is provided for charging a battery in electrically contactless fashion.

9. The rechargeable battery charging case as defined by claim 2, further having a battery charger, which has at least one coupling device that is provided for charging a battery in electrically contactless fashion.

10. The rechargeable battery charging case as defined by claim 1, further having an electronic unit, which is provided for furnishing an adjustable output voltage.

11. The rechargeable battery charging case as defined by claim 2, further having an electronic unit, which is provided for furnishing an adjustable output voltage.

12. The rechargeable battery charging case as defined by claim 1, further having an electronic unit, which is provided for furnishing an alternating voltage.

13. The rechargeable battery charging case as defined by claim 2, further having an electronic unit, which is provided for furnishing an alternating voltage.

14. The rechargeable battery charging case as defined by claim 1, further having at least one USB interface.

15. The rechargeable battery charging case as defined by claim 2, further having at least one USB interface.

16. The rechargeable battery charging case as defined by claim 5, wherein the at least one BUS system has at least two receiving regions for at least one individual, particular unit.

17. A system having a battery and a rechargeable battery charging case as defined by claim 1.

18. The system as defined by claim 17, wherein the battery is provided for being charged, while connected to a power tool, by the rechargeable battery charging case.

19. The battery charger of a rechargeable battery charging case as defined by claim 2.

20. The battery charger of a rechargeable battery charging case as defined by claim 5.
