Abstract
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.
