본 발명의 충전 통신 방법은, EVCC가, 전기차에 전력을 전송하는 프라이머리 어셈블리와 연관되는 SECC 및 EVCC 간에 공유되는 호환성 정보에 기반하여 SECC와 association을 수행하는 단계; SECC와 관련된 SECC 발견 프로토콜(SDP)에 기반하여 동적 무선 전력 전송(D-WPT)을 제공하는 SECC를 EVCC가 식별하는 단계; 및 SECC 및 EVCC 간에 적용될 수 있는 공통 프로토콜을 식별하는 단계를 포함한다.

    A charging communication handoff method according to the present invention comprises steps in which: an EVCC mounted on an electric vehicle transmits a handoff trigger request to a first SECC so that the first SECC corresponding to a first primary assembly for transferring power to the electric vehicle by means of dynamic wireless power transfer (D-WPT) performs wireless LAN scanning in order to search for a second SECC that can support a D-WPT service while being adjacent to the first SECC; and the EVCC transmits, on the basis of the wireless LAN scanning result, a message including the handoff trigger request to the second SECC.
