Abstract
An induction charging device is disclosed. The induction charging device includes at least one coil and at least two magnetic-flux guiding elements spaced apart from one another. At least one gap is disposed between the at least two magnetic-flux guiding elements. A filling assembly is at least partially arranged in the at least one gap. The filling assembly is at least partly magnetically conductive. The filling assembly includes a plurality of layers where at least one layer defines a magnetically conductive layer and at least one other layer defines a magnetically neutral layer. The at least one gap has a gap height, a gap width, and a gap length. The filling assembly, in the at least one gap, is defined of different layers with respect to at least one of the gap height and the gap length.
