Abstract:
A power line for an electric vehicle, comprising:a number of conducting elements (34) arranged in a traveling direction (8) of the electric vehicle (80) and separated electrically from one another;at least a first conducting line (27) supplied with a first polarity;a strip element (60) extending in said traveling direction (8) along substantially the whole length of the line;an enclosure (4) for housing said strip element (60);said strip element (60) being elastically deformable and comprising at least one portion made of ferromagnetic material (65);said strip element (60) being positionable in a rest position in which it extends substantially undeformed along said enclosure;said portion made of ferromagnetic material (65) interacting with a magnetic field generated by excitation means (84) carried by said electric vehicle (80) engaging said line, to attract at least one portion (60a) of said strip element (60) into a contact position in which an electric connection (51, 65, 27) is established between said first conducting line (27) and at least one of said conducting elements (34);characterized by comprising position detecting means (52) for detecting a first arrangement in which said strip element (60) is in said rest position, and a second arrangement in which at least a portion of said strip element (60) is in said contact position.
