Abstract

A method of setting an optimized distance for inductive charging between a coil system of an inductive charging station and a coil system of an electric vehicle includes determining, by the inductive charging station, the optimized distance and calculating position data based on the optimized distance determined. The method also includes transferring the calculated position data to the electric vehicle and calculating a suspension construction for the electric vehicle based on the position data. The method includes transferring data on the calculated suspension construction to a suspension control device of the electric vehicle.
