A coil device for a motor vehicle has a housing which has a receiving area, at least one secondary coil which is arranged in the receiving area for inductively transmitting electric energy in order to charge an energy storage unit of the motor vehicle, and at least one ferrite element which is arranged in the housing for conducting at least one magnetic field in order to inductively transmit the electric energy. The ferrite element has at least two ferrite regions that are at least partly mutually spaced by at least one through-opening which is arranged between the ferrite regions and in which a support structure is at least partly arranged that is made of a fiber composite material and has ferrite elements received in the fiber composite material, wherein opposing housing elements of the housing are supported against each other via said support structure.

Coil device for a motor vehicle, in particular for an automobile

A method is provided for producing an induction coil, in particular for a charging device for the cableless charging of an electrical energy storage device of an electrically driven motor vehicle. At least one coil wire is placed on a carrier fabric in a conductor loop-type coil pattern. The coil wire is stitched to the carrier fabric via at least one stitching wire.

Charging device having an induction coil stitched to a surface of a cross-laid structure

A coil unit for inductive transfer of energy has an induction coil and a ferrite core which cooperates with the induction coil. The ferrite core is produced from a fiber reinforced ceramic material. A motor vehicle is equipped with such a coil unit.
