Abstract

A charging device for charging an electric vehicle with electrical energy includes a charging cable which is able to be connected to a charging connector on the electric vehicle to be charged. The charging device has a drag chain assembly which is configured to transport a set of cables flexibly in the direction of the charging connector in at least one spatial direction and to co-align it with the charging connector of the electric vehicle.

First claim

1 . A charging device for charging an electric vehicle with electrical energy, the charging device comprising:
a charging cable configured to be connected to a charging connector of the electric vehicle to be charged; a set of cables; a drag chain assembly configured to transport said set of cables flexibly in a direction of the charging connector of the electric vehicle in at least one spatial direction and to co-align said set of cables with the charging connector of the electric vehicle.

2 . The charging device according to claim 1 , wherein said set of cables includes at least one of a charging cable or a charge transmission cable or a power transport line or an electrical auxiliary line, and said drag chain assembly is configured to receive, guide and move said set of cables.

3 . The charging device according to claim 1 , wherein said drag chain assembly is configured to guide and move said set of cables in a plurality of spatial directions.

4 . The charging device according to claim 2 , wherein said drag chain assembly is configured to guide and move said set of cables in a plurality of spatial directions.

5 . The charging device according to claim 1 , wherein said drag chain assembly includes at least one of:
at least one drag chain for guiding said set of cables, or at least one plug bracket for entraining a charging plug.

6 . The charging device according to claim 5 , which further comprises at least one drive assembly for moving said at least one drag chain.

7 . The charging device according to claim 6 , wherein said at least one drive assembly includes a linear adjustment unit, and said at least one drag chain is disposed parallel to said linear adjustment unit.

8 . The charging device according to claim 5 , wherein said drag chain assembly is configured to cool said charging cable and said charging plug.

9 . The charging device according to claim 5 , wherein said at least one drag chain is configured to be flexible and deflectable.

10 . The charging device according to claim 5 , wherein said at least one drag chain is configured as a flexible hollow section support in which said set of cables is received at least in portions.

11 . The charging device according to claim 1 , wherein said set of cables is guided without drag chains in a transition between two spatial directions.

12 . The charging device according to claim 2 , wherein said charging cable includes a plurality of stranded copper wires.

13 . The charging device according to claim 12 , wherein said plurality of stranded copper wires are configured as flexible individual lines and are at least one of installation space-optimized or configured depending on an output class.

14 . The charging device according to claim 5 , which further comprises at least one strain relief element, said at least one drag chain having at least one end, and said set of cables being fastened to said at least one end of said at least one drag chain by said at least one strain relief element.
