Ground level power supply system for a non-guided electric vehicle and corresponding method of use
First Claim
1. A ground level power supply system for a non-guided electric vehicle, comprising:
- a pair of power supply tracks including a live conductor track capable of being brought to a supply voltage to supply power to a non-guided electric vehicle travelling over a section of a roadway equipped with the ground level power system, and a neutral conductor track for the return of a current supplied to the non-guided electric vehicle, with the neutral track running parallel to the live track and the live track consisting of a plurality of rectangular segments, disposed end to end, each segment being electrically isolated from adjacent segments thereof;
a first voltage source capable of supplying a low supply voltage and a second voltage source capable of supplying a high supply voltage;
a selector configured to connect each segment to either to the first voltage source or to the second voltage source;
at least one speedometer configured to measure an instantaneous speed of the non-guided electric vehicle; and
a selection device configured to acquire the instantaneous speed of the non-guided electric vehicle measured by the speedometer, compare the measured speed with a threshold speed, and control the selector based on the results of the comparison.

Abstract
A ground level power supply system includes a live track capable of being brought to a supply voltage and a neutral track for the return current, with the live track being constituted of rectangular segments; a first voltage source capable of supplying a low supply voltage and a second voltage source capable of supplying a high supply voltage, each segment being connected by a controlled selector either to the first voltage source, or to the second voltage source; a speedometer capable of measuring the speed of a vehicle travelling over a section of a roadway equipped with the system; and a selection device capable of acquiring the vehicle speed measured by the speedometer, then comparing the speed measured with a threshold speed, and controlling the selector based on the results of the comparison.
