Abstract
A system for remote wireless charging for an electric vehicle using OOFDMA and Risley prisms is proposed. The system includes a receiver configured to transmit location of the receiver and photovoltaic panel size information as a power request signal through V2I, and a transmitter configured to control power transmission based on the information on the power request signal, control a distance between the 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 OOFDM, transmits the signals to areas where the power transmission is available when the prisms are rotated by the predetermined angle, thereby reducing time to find exact locations of the receiver and photovoltaic panel.
