Transferring electric energy to a vehicle by induction

摘要

The invention relates to a system for transferring electric energy to a vehicle, in particular to a road automobile or to a track bound vehicle such as a light rail vehicle, wherein the system comprises an electric conductor arrangement (37) for producing a magnetic field and for thereby transferring the energy to the vehicle, wherein the electric conductor arrangement (37) comprises at least one current line (37a, 37b, 37c), wherein each current line (37a, 37b, 37c) is adapted to carry the electric current which produces the magnetic field or is adapted to carry one of parallel electric currents which produce the magnetic field and wherein: - the current line or lines (37a, 37b, 37c) extend(s) at a first height level, - the system comprises an electrically conductive shield (20) for shielding the magnetic field, wherein the shield (20) extends under the track and extends below the first height level, and - a magnetic core (39) extends along the track at a second height level and extends above the shield (20).
