Abstract

A system for the inductive charging of an energy accumulator of a vehicle, and a charging station, an electronic circuit being provided in the interior of a hood, the opening of which is situated at the bottom side of the hood.

Claims

1-16. -16. (canceled)

17. A system for inductively charging an energy accumulator of a vehicle, comprising:

an electronic circuit arranged in an interior of a hood, the hood having an opening on a bottom side of the hood.

18. The system according to claim 17, wherein the electronic circuit is arranged on an inside wall of a top side of the hood.

19. The system according to claim 17, wherein the electronic circuit is suppliable with electrical energy from a supply line.

20. The system according to claim 19, wherein the supply line is provided in looped-through fashion, and the electronic circuit is suppliable from a T-node.

21. The system according to claim 17, wherein the hood is mounted on a bottom side of a cover and/or a cover plate.

22. The system according to claim 21, wherein the cover includes a ferrite plate, and a primary winding provided on the ferrite plate.

23. The system according to claim 22, wherein a potting compound is provided between the primary winding and the ferrite plate.

24. The system according to claim 22, wherein the electronic circuit is adapted to impress an alternating current upon the primary winding.

25. The system according to claim 24, wherein the alternating current has a frequency between 10 and 500 kHz and/or between 20 and 30 kHz.

26. The system according to claim 22, wherein the vehicle includes a secondary winding to which a capacitor is connected in series or in parallel such that an associated resonant frequency corresponds substantially to a frequency of the alternating current impressed upon the primary winding.

27. The system according to claim 17, wherein the cover is adapted to be driven over by a vehicle.

28. The system according to claim 17, wherein the cover is placeable upon and joinable to a housing part that has at least one lateral opening for a feed-through of a power supply cable.

29. The system according to claim 28, wherein the power supply cable extends to an outside of the housing part in a conduit that extend through the opening in the housing part.

30. The system according to claim 17, wherein the hood is tight and/or airtight.

31. The system according to claim 21, wherein the cover has a support member and/or a plate made of plastic, on a bottom side of which the ferrite plate is disposed, a primary winding being situated on a top side of the ferrite plate, so that the primary winding is positioned between the ferrite plate and the support member and/or the plastic plate, the primary winding being surrounded by a potting compound and/or a cured potting compound, a side wall and/or the hood being joined to the support member, the plastic plate, the potting compound and/or the ferrite plate.

32. The system according to claim 31, wherein the ferrite plate has a multi-piece construction.

33. The system according to claim 21, wherein the cover has a support member and/or a plate made of plastic, aluminum and/o or steel, to whose bottom side the hood is secured, and on whose top side the ferrite plate is disposed, a primary winding being situated on the top side of the ferrite plate.

34. The system according to claim 21, wherein the cover is mounted on a housing part with the aid of a hinge joint.

35. A charging station, comprising:

a plurality of systems recited in claim 17;

wherein the system are suppliable in parallel from a public supply network via a supply line.

36. The charging station according to claim 35, wherein next adjacent housing parts are connected by a respective conduit for a feed-through of a power supply cable.

37. The charging station according to claim 36, wherein at a first axial end area, each conduit is routed through an opening in a respective first housing part, and at a second axial end area, each conduit is routed through an opening in a respective second housing part.
