Abstract

A handheld tool battery charging unit, e.g., for a handheld machine tool battery, has at least one battery accommodation region and at least one detachable battery contact unit provided to be connected to at least one battery pack, as well as at least one charging connection element provided for receiving energy transmitted in a wireless manner.

Claims

1-13. -13. (canceled)

14. A handheld-tool battery charging apparatus, comprising:

at least one battery accommodation region;

at least one detachable battery contact unit configured to be connected to at least one battery pack; and

at least one charging connection unit configured to receive wirelessly transmitted energy.

15. The apparatus as recited in claim 14, further comprising:

at least one detachable machine contact unit configured to transmit the energy to a handheld machine tool.

16. The apparatus as recited in claim 15, wherein the detachable battery contact unit and the detachable machine contact unit are configured in a complementary manner.

17. The apparatus as recited in claim 15, wherein the charging connection unit has an energy receiving coil.

18. The apparatus as recited in claim 15, wherein the detachable machine contact unit has a protective device which prevents energy absorption from a wire-bound charging device.

19. The apparatus as recited in claim 18, wherein the protective device prevents contacting of the wire-bound charging unit.

20. The apparatus as recited in claim 15, further comprising:

a monitoring electronics system configured to monitor at least one charging process.

21. The apparatus as recited in claim 15, further comprising:

a connecting element configured to connect at least one of the detachable battery contact unit, the detachable machine contact unit, and the charging connection unit on at least two different sides of the battery accommodation region.

22. The apparatus as recited in claim 15, wherein the charging connection unit at least partially encloses the handheld machine tool.

23. A system comprising:

a battery pack; and

a handheld-tool battery charging apparatus, including;

at least one battery accommodation region;

at least one detachable battery contact unit configured to be connected to the battery pack; and

at least one charging connection unit configured to receive wirelessly transmitted energy.

24. The system as recited in claim 23, wherein the handheld-tool battery charging apparatus is configured to remain connected to the battery pack when the battery pack is separated from a handheld machine tool.

25. A system comprising:

a handheld machine tool; and

a handheld-tool battery charging apparatus, including;

at least one battery accommodation region;

at least one detachable battery contact unit configured to be connected to the battery pack; and

at least one charging connection unit configured to receive wirelessly transmitted energy.

26. The system as recited in claim 25, wherein the handheld-tool battery charging apparatus is configured to remain connected to the handheld machine tool when the battery pack is separated from the handheld machine tool.
