Abstract
An inductive charging system is provided for a vehicle. A floor unit is designed to generate an electromagnetic charging field for transmitting electrical energy to the vehicle. The floor unit has a first interface which is designed to receive electrical energy in the form of a direct current at the floor unit. The floor unit further has an alternating current generator which is designed to convert the direct current into an alternating current. The floor unit also has a primary coil which is designed to generate the electromagnetic charging field on the basis of the alternating current.
