무선 전력 전송 및 충전 시스템이 개시된다. 무선 전력 전송 및 충전 시스템의 전력전송 장치 동작 방법은 전력 수신기의 높이 별로 핑 신호 조건이 매핑된 핑 벨류 테이블(ping value table)을 유지하는 단계와, 상기 핑 벨류 데이블에 기록된 핑 신호 조건에 따라 핑 신호를 가변하여 전력 수신기를 인식하는 단계 및 상기 전력 수신기로부터 수신된 메시지에 따라 충전 모드를 제어하는 단계를 포함한다. A wireless power transmitting and charging system is disclosed. A method for operating a power transmitter of the wireless power transmitting and charging system comprises the steps of: maintaining a ping value table where ping signal conditions are mapped according to the height of a power receiver; recognizing the power receiver by varying a ping signal according to the ping signal conditions recorded in the ping value table; and controlling a charging mode according to a message received from the power receiver.
