Disclosed are a two-way hydrogen fueling communication process and a device using same, which can overcome the limitations and vulnerabilities of one-way communication and improve the safety, efficiency, and reliability of hydrogen fueling. The two-way hydrogen fueling communication process comprises the steps of: transmitting, to a dispenser, a request message containing a protocol list of communication protocols to be used for a fueling session of hydrogen fueling; and receiving, from the dispenser, a response message containing information about a common protocol selected by the dispenser, most preferred by a vehicle, and mutually supported by both the vehicle and the dispenser, wherein on the basis of the common protocol, the vehicle and the dispenser reach an agreement on the communication protocol to be used for fueling communication of hydrogen fueling. La présente invention concerne un processus de communication bidirectionnelle pour le ravitaillement en hydrogène et un dispositif l'utilisant, qui peuvent surmonter les limitations et les vulnérabilités de la communication unidirectionnelle et améliorer la sécurité, l'efficacité et la fiabilité du ravitaillement en hydrogène. Le processus de communication bidirectionnelle pour le ravitaillement en hydrogène comprend les étapes consistant à : transmettre, à un distributeur, un message de demande contenant une liste de protocoles de protocoles de communication à utiliser pour une session de ravitaillement de ravitaillement en hydrogène ; et recevoir, à partir du distributeur, un message de réponse contenant des informations concernant un protocole commun sélectionné par le distributeur, le plus préféré par un véhicule, et pris en charge mutuellement par le véhicule et le distributeur ; sur la base du protocole commun, le véhicule et le distributeur parvenant à un accord sur le protocole de communication à utiliser pour la communication de ravitaillement du ravitaillement en hydrogène. 단방향 통신의 한계와 취약점들을 극복하고 수소 충전의 안전과 효율 및 신뢰성을 향상시킬 수 있는 수소 충전 통신 양방향 프로세스 및 이를 이용하는 장치가 개시된다. 수소 충전 통신 양방향 프로세스는, 수소 충전의 충전 세션에 사용할 통신 프로토콜들에 대한 프로토콜 리스트를 포함하는 요청 메시지를 디스펜서로 전송하는 단계, 및 디스펜서에 의해 선택되고 차량이 가장 선호하며 차량과 디스펜서 양측에 의해 공통으로 지원되는 공통 프로토콜에 대한 정보를 포함하는 응답 메시지를 디스펜서로부터 받은 단계를 포함하며, 공통 프로토콜에 의해 차량과 디스펜서가 수소 충전의 충전 통신에 사용할 통신 프로토콜에 대해 합의에 도달한다.
