METHOD FOR WIRELESSLY RECHARGING ELECTRIC VEHICLE USING VISIBLE LIGHT COMMUNICATION AND VEHICLE FOR CARRYING OUT THE SAME

摘要

Disclosed is a method for efficiently retrieving a charger to supply electric power to an electric vehicle and achieving maximum wireless recharging efficiency, using visible light communication, upon wirelessly recharging the electric vehicle. Wireless visible light communication can be realized, using the existing head lamp installed at the vehicle. Accordingly, it is unnecessary to provide separate communication equipment. In addition, enhanced physical security, efficient charger retrieval, and maximum wireless recharging efficiency can be achieved by virtue of straightness of light.
