The present invention provides a wireless charging communication method for an electric vehicle, comprising: a charging connection step of establishing a communication relationship between an IVU of vehicle-mounted equipment and a CSU of ground equipment; a charging starting step of the vehicle-mounted equipment and the ground equipment sequentially performing communication operations of compatibility detection pre-test, initial foreign substance detection, initial alignment detection, initial living body protection, and frequency detection and locking; a charging transmission step of the IVU transmitting a charging demand to the CSU in real time, and the CSU adjusting output power depending on the charging demand, the step including a request for the start of charging and a power transmission communication interaction process; and a charging stopping step of, if charging stopping conditions are satisfied, both the IVU and the CSU capable of determining and initiating a charging stopping request, and transmitting the charging statistics data of the whole charging process to each other after charging is stopped. The wireless charging communication method for an electric vehicle according to the present invention realizes normal, efficient and safe interaction during the wireless charging of an electric vehicle.

    본 발명은 전기차 무선 충전 통신 방법을 제공한다. 여기에는 차량 탑재 장비의 IVU와 지면 장비의 CSU가 통신 관계를 구축하는 충전 연결 단계; 차량 탑재 장비와 지면 장비가 호환성 검출 사전 검사, 초기 이물질 검출, 초기 정렬 검출, 초기 생체 보호 및 주파수 검출과 잠금의 통신 작업을 순차적으로 실행하는 충전 가동 단계; IVU가 실시간으로 CSU에 충전 수요를 전송하고, CSU가 충전 수요에 따라 출력 전력을 조정하는 충전 전송 단계 - 해당 단계에는 충전 시작 요청 및 전력 전송 통신 상호작용 프로세스가 포함됨 - ; 및 충전 정지 조건이 충족되면 IVU와 CSU가 모두 충전 정지 요청을 판단하여 개시할 수 있으며, 충전이 정지된 후, 전체 충전 프로세스의 충전 통계 데이터를 서로 전송하는 충전 정지 단계가 포함된다. 본 발명에 따른 전기차 무선 충전 통신 방법은 전기차 무선 충전 시의 정상적이고 효율이 높으며 안전한 상호작용을 구현한다.
