Abstract

A system and a method for validating electric vehicles in a network are provided herein. The method may include the following steps: transmitting energy from at least one road section to at least one electric vehicle; recording a magnitude of energy received by said at least one electric vehicle and transmitting a record of said magnitude of energy received for validation; recording a magnitude of energy transmitted from said at least one road section and transmitting a record of said magnitude of energy transmitted for validation; and validating energy usage of said at least one electric vehicle by periodically comparing said magnitude of energy received with said magnitude of energy transmitted to identify at least one of: component failure; and, a potential fraud. The system implements the method in a power-over-the-air network for electric vehicles.

Abstract

A system for wireless power transfer of on-road vehicles is provided herein. The system includes a plurality of base stations; a power transmission line located beneath a surface of a road having a plurality of segments, each segment having at least one pair of coils and at least one capacitor electrically connected via a switch to the coils in the segment; and at least one vehicle having at least one power receiving segment having at least two coils, connected to at least one capacitor, wherein the at least one vehicle further includes a communication transmitter configured to transmit a power requesting signal, wherein the coils of the power transmitting segment are configured to receive the power requesting signal; and wherein each of the base stations is further configured to feed a plurality of the power transmitting segments with current at a resonance frequency, responsive to the power requesting signal.

Abstract

A system and method for powering an electric vehicle on a road, the system comprising a generator configured to produce power, an inductive accumulator array for installation in a road configured to receive power from the generator, a receiver array of receiver coils for installation beneath a vehicle, each coil being configured to receive power from a corresponding accumulator coil installed in a road, wherein said receiver array is configured to provide excess power back to the accumulator coils, said excess power being providable to other vehicles by the accumulator array. The system further comprises a vehicle communications coil for location in a vehicle in front of the receiver array in the driving direction of the vehicle, and an accumulator communications unit configured to receive a signal from said vehicle communications coil and to operate corresponding accumulator sections to provide power to a receiver attached to the vehicle.
