SYSTEM AND METHOD FOR POWERING ON-ROAD ELECTRIC VEHICLES VIA WIRELESS POWER TRANSFER
First Claim
1. A system for wirelessly powering on-road vehicles, the system comprising:
- a plurality of base stations configured to output an alternating current at a specified frequency;
a power line located beneath a surface of a road and comprising a plurality of independently switched power transmitting segments each comprising at least one pair of coils connected electrically in series to at least one capacitor electrically and via a switch to one of the base stations, forming a switched power transmission inductance circuitry; and
at least one vehicle having at least one power receiving segment having at least two coils and at least one capacitor forming a power receiving inductance circuitry,wherein the at least one vehicle further comprises a communication transmitter configured to transmit a power requesting signal,wherein the coils of the power transmitting segment are configured to receive said power requesting signal;
wherein the base station associated with the coils of the power transmitting segment receiving said power requesting signal is further configured to feed said power transmitting segment with the alternating current at the specified frequency being a resonance frequency of said power transmission and receiving inductance circuitries, responsive to the power requesting signal.
