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.

A charging configuration for inductive wireless transfer of energy to a receiving coil of an electrically operated vehicle, the charging configuration comprising:
- a first circularly wound electrically conductive coil extending in a given plane and having a first central opening formed in a center of said first coil;
- a second circularly wound electrically conductive coil extending in a given plane and having a second central opening formed in a center of said second coil;
- said first and second coil having a bottom edge and being disposed in a coplanar relationship;
- a ferrite core;
- a shielding sheet with a rectangular base plate supporting said ferrite core and said coplanar coils thereon;
- and
- a coil holder configured to hold said first and second coils on said shielding sheet to maintain a distance of between 15 and 25 mm between said shielding sheet and said bottom edge of said coils.
