System for remote wireless charging for electric vehicle using OOFDMA and risley prisms

A system for remote wireless charging for an electric vehicle using an optical orthogonal frequency division multiple access (OOFDMA) and Risley prisms, the system comprising:

• a receiver configured to transmit location of the receiver and photovoltaic panel size information as a power request signal through a vehicle-to-infrastructure (V2I);
• and
• a transmitter configured to control power transmission based on the information on the power request signal, control a distance between the Risley prisms according to the location of the receiver and the size of a photovoltaic panel, transmit transmission power information (PowerInfo) for all laser signals to be received by the photovoltaic panel, and rotate the Risley prisms by a predetermined angle,
• wherein the transmitter, after generating the transmission power information for each wavelength by an optical orthogonal frequency division multiplexing (OOFDM), transmits the signals to areas where the power transmission is available when the Risley prisms are rotated by the predetermined angle.
