8. A charging station for a vehicle equipped with a charging module in an underbody of the vehicle, the charging module comprising a secondary coil and having a localization magnet, the charging station comprising:
-
a housing; a charging unit comprising a primary coil and a positioning magnet, the charging unit being floatingly disposed in the housing of the charging station so as to be provided with a predefined horizontal movement area within the housing, wherein an interaction of the positioning magnet with the localization magnet of the charging module causes an attractive positioning force that horizontally moves the charging unit floatingly disposed in the housing of the charging station. - View Dependent Claims (9, 10)

11. A method for charging a vehicle, equipped with a charging module in an underbody thereof, by a stationary charging station equipped with a charging unit for inductively charging a battery of the vehicle, the charging station being disposed close to or in the ground and having a charging unit floatingly disposed in the charging station so as to be movable in a predefined horizontal movement area via an attractive positioning force between a positioning magnet of the charging unit and a localization magnet of the charging module, the method comprising the acts of:
-
moving the vehicle into a stopping position in which the charging module is located above the predefined horizontal movement area; in the stopping position, floatingly moving the charging unit by the attractive positioning force into a charging position relative to the charging module; and when the charging position is reached, inductive energy transfer between a primary coil of the charging unit and a secondary coil of the charging module is locally maximal with respect to a position of the charging unit in the predefined horizontal movement area, wherein charging of a battery of the vehicle occurs. - View Dependent Claims (12)
