Abstract
A charging station for wireless energy-transfer coupling of an electrically powered vehicle has a terminal for an electrical energy source and an electronic coil that generates an alternating magnetic field. The electronic coil has a cylindrical winding and a ferromagnetic body. A front face of the winding abuts against the ferromagnetic body in order to couple the alternating magnetic field issuing from the winding via the front face into the ferromagnetic body. The winding has a first winding and a second winding which are arranged next to one another and with their front faces abutting against the ferromagnetic body. The two windings generate an opposing alternating magnetic field. A space encompassed by the first and second windings respectively contains a ferromagnetic material.
