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.

First claim

The invention claimed is:

1. A charging station in a first space of a building having a second space, 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, 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 in the building, heat being conducted from the first space to the second space via the side wall of the container.

2. The charging station as claimed in claim 1 , 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.

3. The charging station as claimed in claim 2 , wherein the container is located in a separate space below the ground level.

4. The charging station as claimed in claim 2 , wherein the container is housed in the hollow space into which the charging post is retractable.

5. The charging station as claimed in claim 2 , wherein the hollow space is located in the container.

6. The charging station as claimed in claim 5 , wherein the container is constructed of a material and in a shape that transfers heat generated inside the container to outside of the container.

7. The charging station as claimed in claim 6 , 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.

8. The charging station as claimed in claim 7 , 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.

9. The charging station as claimed in claim 8 , wherein the container further includes a hatch, providing maintenance access, that can be opened and closed.

10. The charging station as claimed in claim 2 , wherein the container and charging post are embodied as one unit located in the hollow space when the charging post is retracted.

11. The charging station as claimed in claim 10 , wherein the container has a power connection and no other connection.

12. The charging station as claimed in claim 1 ,
further comprising heat emitting components located in the container, and
wherein, during operation of the charging station, the heat emitting components in the container are thermally connected to the outer wall of the container via at least one of heat conduction and heat convection.

13. The charging station as claimed in claim 12 , wherein the charging station is a direct current charging station.
