Abstract
A buried power supply system for an electric vehicle (,) equipped with collector shoes (,), the system comprising a succession of conductive segments (,A,,B,,C) that are electrically isolated from one another, and that form a conductive track for the shoes on a road surface. Each segment is provided with individual switching means (,) of the static type, which means are received under the segment in a trough along which a common power supply link (,) and a common return link (,) run. The switching means provide electrical continuity between the segment to which they are assigned and the power return link so long as a connection control signal for connecting a segment to the power supply link is not received from a vehicle either directly by the segment in question (,C) or by either of the immediately adjacent segments (,B,,D). The vehicles include means for transmitting a connection control signal to a segment of track.
