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.

A charging arrangement for a vehicle includes: a charge receiving connector secured to the roof of a vehicle at a fixed height from the roof of the vehicle, the charge receiving connector including at least three elongate charge receiving conductors longitudinal axes of the charge receiving conductors being disposed substantially along the same line; and a charging gantry including at least three charging conductors, the charging conductors being vertically movable between a raised position in which the charging conductors are clear of the vehicle when the vehicle is under the charging gantry, and a lowered position in which the charging conductors make contact with the charge receiving conductors on the roof of the vehicle.

An electrical power supply system with assistance with the making of electrical contact, of a type having a power supply arm mounted on a post positioned alongside the road, entering into electrical contact with a longitudinal conductor rail carried on the vehicle, is characterized in that the arm hasat its enda means of rolling or sliding that enters into moving contact with an adjacent lane alongside the conductor rail at the beginning of its length. This invention concerns the domain of electrically-propelled vehicles carrying at least one longitudinal power supply rail.

A power supply device for a vehicle includes at least one contact head which can be connected to a vehicle and can be brought in contact with a docking station, wherein a contact head roll mechanism is rotatably connected to the at least one contact head and connected so as to be able to be brought in contact with the docking station, where the contact head roll mechanism includes at least two rolls or at least two rollers, via which a rolling contact can be established between the at least one contact head and the docking station, and where a first roll or a first roller is arranged on a first flank of the at least one contact head, and a second roll or a second roller is arranged on a second flank, located across the first flank, of the at least one contact head.

A wireless power supply system is a wireless power supply system provided with a travel lane for wirelessly transmitting power to a moving body and includes a power transmitting coil that is disposed such that the axial direction of the coil is substantially parallel to the width direction of the travel lane, and electromagnetic shielding walls that are disposed on the respective sides of the travel lane in the extension direction of the travel lane.

A charging station for an electric vehicle having a charging blade may include a charge head configured to electrically connect with a charging blade of a vehicle to charge the vehicle, the charge head extending from a front end to a rear end along a longitudinal axis that extends along a direction of travel of the vehicle. The charge head may include a first housing and a second housing, wherein the first and second housings are (a) symmetrically positioned about the longitudinal axis and (b) separated by a channel that extends from the front end to the rear end of the charge head, the channel being dimensioned to position the charging blade therein. The charge head may further include one or more charging brushes located in each of the first housing and the second housing, wherein each of the one or more charging brushes in each housing is configured to extend into the channel towards the other housing to contact the charging blade positioned in the channel. The charge head may also include one or more sensors located in at least one of the first housing or the second housing, wherein the one or more sensors is configured to detect a presence of the charging blade in the channel.

A vehicle power supply system is configured to supply power to a vehicle from a power supply apparatus laid on a power supply lane of a vehicle travel path, the power supply apparatus includes a plurality of power supply segments laid in a preset interval along the power supply lane, and a controller configured to control the plurality of power supply segments. The controller is configured to estimate timing of the vehicle reaching a next power supply segment that supplies power next after a present power supply segment that is supplying power, from at least a vehicle velocity derived from a change in position of the vehicle, and cause the next power supply segment to start power supply at the timing estimated.
