Abstract

A charging configuration for the inductive wireless energy transfer to a receiver coil of an electrically operated vehicle. A first circularly wound electrically conductive coil extends in a plane and has a first central opening in the center of the first coil. A second circularly wound electrically conductive coil extends in a plane, coplanar with the first coil, and has a second central opening formed in its center. A ferrite core is supported on a shielding sheet with a rectangular base plate together with the coplanar coils. The coils are arranged in a coil holder on the shielding sheet such that a distance of between 15 and 25 mm remains between the shielding sheet and the bottom edge of the coils.
