<p>Electric road vehicles are charged while either stationary or moving along a roadway through electrical conductors 2 aligned in the direction of travel on a road surface. Electrically conductive brushes 3 extend downwards from a vehicle and make contact with the tracks 2. Power supply from the rails 2 to identified vehicles is triggered only when a series of precaution conditions are met, to ensure the safety of pedestrians. Weight sensors 1 are positioned either side of the rails 2 and detect the presence of a suitable vehicle; the vehicle itself can be identified through electrical signals transmitted through electrically conductive tyres to the weight sensors 1, where the signals are detected by control unit 9, which in turn controls power to the rails 2. A residual current device (RCD) disables power supply to the rails 2 if a leakage current to the surroundings is detected. To improve road drainage and safety, the tracks 2 may be positioned at the bottom of narrow channels (5, fig. 4) in the road surface.</p> |
