Wireless charging system for vehicles

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.

1 . A wireless charging system for vehicles, said wireless charging system comprising a transmitter system and further comprising a receiver system, said transmitter system to wirelessly transmit power to said receiver system, said transmitter system wirelessly coupled to the said receiver system using magnetic resonant coupling, said transmitter and receiver systems comprising tuned electromagnetic circuits to perform wireless power transfer from the said transmitter system to the said receiver system, said receiver system comprising at least one rechargeable battery system wirelessly coupled to the said transmitter system to charge the said rechargeable battery, and the said receiver system further comprising a load operated by the said rechargeable battery system, when the said rechargeable battery is charged. 
     
     
         2 . A wireless charging system for vehicles, said wireless charging system comprising a transmitter system and further comprising a receiver system, said transmitter system to wirelessly transmit power to said receiver system, said transmitter system comprising at least one light or laser or infrared laser transmitting device coupled to the said receiver system using visible or invisible light spectrum coupling, said receiver system comprising at least one visible or invisible light detector panel to receive the energy transmitted by said transmitter, said receiver system further comprising at least one rechargeable battery system wirelessly coupled to the said transmitter system to charge the said rechargeable battery, and the said receiver system further comprising a load operated by the said rechargeable battery system, when the said rechargeable battery is charged. 
     
     
         3 . The transmitter system of  claim 1  further comprises: a. a power source to supply power to said transmitter system and b. a tuned electromagnetic resonant coupling transmitter coil to transmit said power to said receiver system. 
     
     
         4 . The receiver system of  claim 1  comprising a first rechargeable battery, and further comprising a second rechargeable battery, said first rechargeable battery providing power to operate said load when said second rechargeable battery is coupled to the said transmitter system for charging. 
     
     
         5 . The receiver system of  claim 2  comprising a first rechargeable battery, and further comprising a second rechargeable battery, said first rechargeable battery providing power to operate said load when said second rechargeable battery is coupled to the said transmitter system for charging. 
     
     
         6 . The power source of  claim 3  comprising hydroelectric power, solar power, nuclear power, geothermal power, coal power or wind power source or the like or a combination to power the said transmitter system.
