Abstract

The invention relates to a charging contact unit (100, 1100) for a vehicle, for integrating beneath a road surface, with a charging contact element carrier head (113, 1113) designed to interact with a contact device on the lower side of a vehicle, the contact making and the contact separation being carried out by a relative movement of the charging contact element carrier head and the contact device in a contacting direction (6), the charging contact element carrier head (113, 1113) being movable inside the charging contact unit and/or rotatable or pivotable about the contacting direction (6) in order to compare incorrect positioning in either one or a plurality of directions extending transversely to the contacting direction (6). The invention also relates to a contact system and a road covering.
