Induction charging device for a vehicle charging system

An arrangement of magnetic-flux guiding elements for an induction charging device, comprising:

• at least two magnetic-flux guiding elements spaced apart from one another,
• at least one gap disposed between the at least two magnetic-flux guiding elements that are spaced apart from one another,
• wherein the at least one gap is filled partly or entirely by a filling assembly with a plurality of layers,
• wherein the at least two magnetic-flux guiding elements, spaced apart from one another, provide together with the filling assembly in the at least one gap an assembly that is able to be mounted in one piece,
• wherein at least one layer of the filling assembly defines a magnetically conductive layer and at least one other layer of the filling assembly defines a magnetically neutral layer,
• wherein the at least one gap has a gap height corresponding to a thickness of the at least two magnetic-flux guiding elements, a gap width corresponding to a distance between adjacent faces of the at least two magnetic-flux guiding elements, and a gap length extending in a direction transversely to the gap height and the gap length, and
• wherein the filling assembly, arranged 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 including the magnetically conductive layer and the magnetically neutral layer.
