ABSTRACT:
TECHNICAL FIELD
The present invention relates to a power line for an electric vehicle.
BACKGROUND ART
Power lines for electric vehicles—such as the one described in German Patent n° 1.011.914 by Ludwig Reihardt, published on Jul. 11, 1957—are known to comprise an elongated insulating enclosure closed at the top by a number of conducting plates aligned in a straight direction and insulated from one another. The enclosure houses an elastically deformable conducting strip element made of ferromagnetic material, and which is attracted by the magnetic field generated by electromagnets to flex a portion of the conducting strip element towards the conducting plates to electrically supply at least one.
French Patent n° 1.151.382 by Jean-Florent DE BRUYN and Josè-Gaston DE BRUYN, published on Jan. 29, 1958, describes an electric vehicle current supply system comprising a hollow elongated insulating enclosure closed at the top by a number of conducting plates aligned in the traveling direction of the vehicle and separated by insulating elements interposed between adjacent conducting plates. The enclosure houses an elastically deformable conducting strip element extending in the traveling direction of the vehicle, and having a strip portion of ferromagnetic material on which is superimposed a strip portion of good electrically conducting material. The conducting element is attracted by the magnetic field generated by electromagnets on an electric vehicle to flex a portion of the conducting strip element towards the conducting plates to electrically supply at least one.
The power lines described in the above patents have no means by which to determine the location of the electric vehicle along the line.
DISCLOSURE OF INVENTION
It is an object of the present invention to provide a power line of the above type, which also provides for determining the location of the electric vehicle along the line. It is a further object of the present invention to provide a power line defined by a number of elementary modules connectable to one another, and which provides for detecting the elementary module along which the electric vehicle is traveling.
According to the present invention, there is provided a power line of the type described in claim
