Method for automatically establishing a plug-in connection in order to charge electric vehicles

A device for automatically establishing a plug-in connection for charging electric vehicles, said device comprising:

• a positioning unit that has
• a positioning head that is supported for displacement in at least two spatial directions and has a free plug-in connector and an alignment sensor supported thereon, and
• a position sensor determining a position of the positioning head relative to a permanently installed plug-in connector;
• wherein the positioning unit has transverse-force sensors operatively associated with the positioning head, and
• wherein each of the free plug-in connectors has at least one respective guide surface with a distance from a cooperating guide surface of the other plug-in connector along a common plug-in axis of the plug-in connectors decreases continuously from an insertion position towards a plug-in position;
• and
• wherein one of the plug-in connectors is mounted so as to be pivotable with adjustable stiffness transversely to the plug-in axis and/or about a pivot axis extending transversely to the plug-in axis.
