Abstract
A supply line (1) for an electric vehicle (80) has a plurality of conductive plates (34) alternating with insulating plates (37) and disposed along a top of a long hollow insulating casing (4) in a direction of travel for an electric vehicle (80). An elastically deformable ribbon-like conductive element (60) including a strip of ferromagnetic material (63) is also disposed in the hollow casing (4). The ribbon-like conductive element (60) is attracted by a magnetic field induced by electromagnets (84) carried by the electric vehicle (80) to cause deflection of the portion of the ribbon-like conductive element (60) towards the conductive plates (34) until at least one conductive plate (34) contacts a supply line carried within the casing (4). The electric vehicle (80) also has at least one pickup (87) which contacts the conductive plates (34) to supply electricity of at least one polarity to the electric vehicle (80).
