Ground assembly for wireless charging of electric vehicles and method for controlling the wireless charging thereof

Abstract

A ground assembly for wireless charging of electric vehicles according to an embodiment of the present invention includes: a transmitting coil; a power supply unit capable of supplying power to the transmitting coil; a detection sensor unit capable of detecting foreign matter in an external matter detection area surrounding the transmitting coil; and a control unit for detecting foreign matter using the detection sensor unit, measuring the distance to the detected foreign matter, determining the presence of foreign matter in the foreign matter detection area based on the measured distance, and controlling the power supplied to the transmitting coil based on the determination result. The detection sensor unit includes at least one of a sonar sensor, a lidar, and a camera device. The foreign matter detection area can be within a predetermined distance from the edge of the transmitting coil in a direction parallel to the ground surface, and can be within a predetermined distance from the upper part of the transmitting coil in a direction perpendicular to the ground surface.
