Problems solved by technology

Therefore, when there is a substance (such as metal or magnetic material) that can affect the magnetic field between the transmitting coil and the receiving coil, it directly affects the resonant frequency of the WPT system, resulting in abnormal operation of the WPT system or a decrease in the efficiency of the WPT

Abstract

The invention relates to a method and an apparatus for controlling wireless power transfer to an electric vehicle using an object detection sensor. A wireless power transfer (WPT) control method usingan object detection sensor, performed at a WPT apparatus, may include detecting whether or not an object exists between a transmission pad and a reception pad mounted on an electric vehicle (EV) using an object detection sensor; in response to detecting that an object does not exist between the transmission pad and the reception pad, controlling the transmission pad to perform WPT to the reception pad; and in response to detecting that an object exists between the transmission pad and the reception pad, generating ultrasonic waves using an ultrasonic wave generator.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2016-0116645 filed on September 9, 2016 and Korean Patent Application No. 10-2017-0110005 filed on August 30, 2017, the entire contents of which are All purposes are hereby incorporated by reference. technical field [0003] The present invention relates to a method and apparatus for controlling wireless power transfer (WPT) to an electric vehicle (EV), and more particularly, to a method and apparatus for communicating with a receiving board when a transmitting board is detected using an object detection sensor. When various objects such as animals are placed between the plates, the stability of the WPT is enhanced by preventing the entry of various objects that interfere with the WPT by generating ultrasonic waves. Background technique [0004] An electric vehicle (EV) charging system can basically be defined as a system that charges a high-volta...
