Vehicle connection device, ground contact unit, vehicle coupling system and method for automatically conductively connecting a vehicle contact unit with a ground contact unit

A vehicle connection device for a vehicle battery charging system for automatically conductively connecting a vehicle contact unit to a ground contact unit, comprising:

• the vehicle contact unit that has a base with a contacting area in which at least one first contact electrode, at least one second contact electrode and at least one third contact electrode are provided, wherein the vehicle contact unit is moveable towards the ground contact unit in a contact direction in order to bring said at least one first contact electrode, said at least one second contact electrode and said at least one third contact electrode in contact with the ground contact unit,
• an aligning actuator that is connected to the base in such a way that it is able to rotate the base about an axis of rotation running substantially in the contact direction,
• wherein a magnetic area is provided in the contacting area, in said magnetic area a contact magnet is located in or on the base, wherein the contact magnet determines a position of the axis of rotation, wherein the axis of rotation runs through the contact magnet.
