The position-determining system serves to determine a position of a contact interface of the vehicle in relation to a charging interface of the charging station. The position-determining system determines the position visually in at least two dimensions. As a result of the at least two-dimensional determination of the position, the vehicle is not tied to a predefined route. This increases the reliability of the positioning of the vehicle when it approaches the charging station. ## Claims ### Claim 1 A charging station for an at least partly electrically driven vehicle having a contact interface, the charging station comprising: a position-determining system having a camera and an analysis unit configured to determine a position of the contact interface using images from said camera; a charging interface; and an infrared illumination unit for illuminating a region with infrared light, wherein the region containing at least one position tolerance region in which the contact interface must be disposed so as to be contactable by means of the charging interface. ### Claim 2 (depends on 1) The charging station according to claim 1, wherein said position-determining system is configured to determine the position of the contact interface using geometric features of the contact interface. ### Claim 3 (depends on 1) The charging station according to claim 1, wherein said camera is an infrared camera. ### Claim 4 (depends on 1) The charging station according to claim 1, wherein a position determination includes determining a distance of the contact interface from said charging interface using a size of a position marker disposed on the contact interface in a camera image. ### Claim 5 (depends on 1) The charging station according to claim 1, wherein the charging station is configured to only enable a charging process if a result of a position determination is that the contact interface is disposed in the position tolerance region. ### Claim 6 A system, comprising: a vehicle being driven at least partly electrically, said vehicle containing a storage device for electrical energy and a contact interface; a charging station, containing: a position-determining system having a camera and an analysis unit configured to determine a position of said contact interface using images from said camera; a charging interface; an infrared illumination unit for illuminating a region with infrared light, wherein the region containing at least one position tolerance region in which said contact interface must be disposed so as to be contactable by means of said charging interface; said charging station configured to only enable a charging process if a result of a position determination is that said contact interface is disposed in the position tolerance region; and said contact interface being contacted by said charging interface of said charging station so that said storage device can be charged, said contact interface having at least one position marker. ### Claim 7 (depends on 6) The system according to claim 6, wherein said position marker is embodied to selectively reflect or radiate light in a specified range of wavelengths. ### Claim 8 (depends on 6) The system according to claim 6, wherein said vehicle having a heating element for heating said position marker. ### Claim 9 (depends on 6) The system according to claim 6, wherein said vehicle and said charging station each have a unit for data transmission and said charging station is embodied to transmit a determined position to said vehicle. ### Claim 10 (depends on 6) The system according to claim 6, wherein: said charging station and/or said vehicle has a telemetry unit for telemetering a determined position; and said vehicle has a display and is configured to display a transmitted position of said vehicle on said display. ### Claim 11 (depends on 6) The system as claimed in claim 6, wherein said position marker has geometric figures or codes and by means of said geometric figures or codes, information is transmitted that enables positive association of said vehicle with said charging station. ### Claim 12 (depends on 6) The system according to claim 6, wherein said position marker has light-emitting diodes and by means of said light-emitting diodes, information is transmitted that enables positive association of said vehicle with said charging station.
