Abstract
A system of energy storage and charging usable in vehicles and other applications that eliminate the battery capacity and automotive range issues is described. In our invention, vehicles are equipped with charging mechanisms to charge and recharge onboard batteries using wireless electricity and power transmission using magnetic resonant coupling between tuned electromagnetic circuits. The batteries may be charged using wireless charging systems installed along the roads while the vehicle is in use on the road. Charging system may optionally utilize infrared laser beam radiation to transmit power for charging the batteries on board a vehicle while it is in use as well. The onboard vehicle batteries may also be charged when the vehicle is not being driven either by plugging in the vehicle into wall electricity using wired power connection or may be wirelessly charged using the magnetic resonant coupling. By locating the charging circuits on roads, a continuous operation of electric-only mode of hybrid vehicles or pure electric-only vehicles can be accomplished and fully eliminate the need for gasoline usage.
