전기차 무선 전력 전송을 위한 무선 통신 방법 및 장치가 개시된다. 전기차에 탑재된 무선 충전 제어 장치에서 수행되는, 전기차 무선 전력 전송(Wireless Power Transfer, WPT)을 위한 무선 통신 방법은, 상기 무선 충전 제어 장치에 미리 저장된 AP(Access Point) 식별 정보를 포함하는 프로브 요청(probe request) 메시지를 적어도 하나의 차징 스테이션에 전송하는 단계, 상기 AP 식별 정보에 상응하는 차징 스테이션(charging station)으로부터 프로브 응답(probe response) 메시지를 수신하는 단계, 인증 암호 정보를 상기 차징 스테이션에 전송하여 무선 통신을 위한 인증(Authentication)을 수행하는 단계 및 상기 무선 통신을 위한 인증이 완료되면, 상기 무선 충전 제어 장치에 미리 저장된 사용자 인증 정보를 이용하여 상기 전기차의 무선 전력 전송을 위한 사용자 인증을 수행하는 단계를 포함한다.

    Disclosed are a method and apparatus for wireless communication for wireless power transfer (WPT) to an electric car. The method for wireless communication for WPT to an electric car, which is performed by a wireless charging control device mounted on an electric car, comprises the steps of: transmitting a probe request message including access point (AP) identification information previously stored in the wireless charging control device to at least one charging station; receiving a probe response message from the charging station, which corresponds to the AP identification information; transmitting information on authentication password to the charging station to perform authentication for wireless communication; and using information on user authentication previously stored in the wireless charging control device to perform user authentication for WPT to the electric car when the authentication for wireless communication is completed. The present invention can provide a customized service including a vehicle software update through user information stored in an electric car.
