Charging device and method for establishing an electrical connection between a charging device and a motor vehicle for charging an electrical energy storage of the motor vehicle

摘要

The invention relates to a charging device (1) for producing an electrical connection for charging an electrical energy store of a motor vehicle (2), with a first connecting unit (7) for establishing an electrical connection to a corresponding second connecting unit of the motor vehicle (2), the first connection unit (7) is arranged on a base (15) on which the motor vehicle (2) can be parked for loading. In order to further develop the charging device (1) in such a way that a lower complexity is made possible, the following is provided: a ramp (3) which allows the motor vehicle (2) to be driven up with at least one wheel for initiating the charging process, the ramp (3) comprises a first hydraulic cylinder (4), wherein the first hydraulic cylinder (4) is designed to apply a weight force via a hydraulic medium (19) to a second hydraulic cylinder (6) of the charging device (1) as a result of loading the ramp (3) ) is pressurized, wherein the second hydraulic cylinder (6) is adapted to move the first connection unit (7) due to a pressurization of the second hydraulic cylinder (6) vertically.
