Abstract

A charging post at a charging station for charging an electric vehicle can be lowered into the ground by a lifting device such that it does not become a physical obstacle or optically impair the environment and is not damaged by external influences.

Claims

1-18. -18. (canceled)

19. A charging post for an electric vehicle, connectable via a charging cable to the electric vehicle, comprising:

a main body;

a control unit, including a display device and an input device, mounted in the main body; and

means for extending and retracting the main body out of and into a hollow space.

20. The charging post as claimed in claim 19, wherein said means for extending and retracting the main body retracts the main body into the hollow space in an idle state, and extends the main body out of the hollow space in an electric vehicle charging state.

21. The charging post as claimed in claim 20, wherein no electrical and electronic components required for charging the electric vehicle are housed in the charging post.

22. The charging post as claimed in claim 21, wherein the display device and input device is a touch-sensitive display.

23. A charging station for charging an electric vehicle via a charging cable, comprising:

a charging post retractable and extendable into and out of a hollow space and including a control unit having a display device and an input device;

a drive device, embodied as a lifting, sliding or hinged device, moving the charging post into and out of the hollow space; and

a container housing at least some electrical and/or electronic components required for charging the electric vehicle and to which the charging cable can be electrically connected.

24. The charging station as claimed in claim 23, wherein the hollow space into which the charging post is retractable is one of below ground level, in or behind a side wall and in a ceiling.

25. The charging station as claimed in claim 24, wherein the container is located in a separate space below the ground level.

26. The charging station as claimed in claim 24, wherein the container is housed in the hollow space into which the charging post is retractable.

27. The charging station as claimed in claim 24, wherein the hollow space is located in the container.

28. The charging station as claimed in claim 27, wherein the container is constructed of a material and in a shape that transfers heat generated inside the container to outside of the container.

29. The charging station as claimed in claim 28, wherein the container has an outer wall that is at least one of made from galvanized sheet steel, formed with external fins and #components located in the interior of the container which output heat during the operating state of the charging station are thermally connected to the outer wall of the container, in particular via heat conduction and/or heat convection.

30. The charging station as claimed in claim 29, wherein the container further includes at least one of a power connection connectable a power supply for the charging station, and a cable connection to which the charging cable can be connected.

31. The charging station as claimed in claim 30, wherein the container further includes a hatch, providing maintenance access, that can be opened and closed.

32. The charging station as claimed in claim 24, wherein the container and charging post are embodied as one unit located in the hollow space when the charging post is retracted.

33. The charging station as claimed in claim 32, wherein the container has a power connection and no other connection.

34. The charging station as claimed in claim 23, wherein the container is housed in a first space of a building having a second space, at least part of an outer wall of the container forming at least a portion of one of a wall and a floor of the second space, heat being conducted from the first space to the second space via the side wall of the container.
