An electrical power supply system for an electrically propelled vehicle provided with a traction unit and an electrical connector and moving along a circulation rail includes an external power supply zone having a supply line extending along the circulation rail for connection with the electrical connector, and an autonomous power supply zone, located after the external power supply zone along the circulation rail. The supply line includes a main section. The supply line includes a terminal section, extending along the circulation rail in the external power supply zone at least between a first end of the main section and the autonomous power supply zone, for connection with the electrical connector, and a diode, electrically connecting the first end of the main section and a second end of the terminal section and designed to let an electrical current pass through from the main section to the terminal section.

Disclosed is a road for charging electric vehicle. The road includes an electrified rail which includes an electrode plate for connecting an electric plate of the electric vehicle, an insulated cover covering on the plate electrode so as to prevent electric leakage and a neutral layer covering on the insulated cover for connecting a neutral electrode plate of the electric vehicle. The electrode plate includes a first electrode plate and a second electrode plate. The first electrode plate is disposed above the second electrode plate and between the first electrode plate and the second electrode plate there is a gap so that the electric plate of the electric vehicle is able to be sandwiched between the first electrode plate and the second electrode plate while charging. According to the present invention, the road surface is provided with electrified rail, thus the electric vehicle can charge while driving.

This system for powering an overhead contact line, which includes a contact wire consisting of a plurality of conductive sections separated by insulating sections, includes power supply sub-stations, each conductive section being connected, on the side of an upstream end, to an upstream sub-station via an upstream controlled switch and, on the side of a downstream end, to a downstream sub-station via a downstream controlled switch. This system includes a detection device, associated with a conductive section, to be monitored, which includes a means for transmitting a characteristic signal to an upstream or downstream end of said conductive section and a receiving means able to receive the characteristic signal at the other end, the receiving means modifying the value of a state signal applied to a control circuit for actuating the opening of the downstream switch and/or of the upstream switch.
