본 발명은 전기차 충전시스템 내에서 OCPP를 기반으로 하는 충전 스테이션 관리시스템과 충전스테이션 사이의 통신 방법을 개시하는 것으로, 본 실시예의 전기차 충전시스템 내에서 OCPP를 기반으로 하는 충전 스테이션 관리시스템과 충전스테이션 사이의 통신 방법은, 전기차 충전시스템에서의 충전 스테이션 관리시스템과 충전 스테이션 사이의 OCPP 메시지를 처리하는 방법에 있어서, (a) 상대 OCPP Entity로부터 OCPP 메시지를 수신하여 Message Handler로 전달하는 단계, (b) 전달받은 OCPP 메시지의 유효성을 검사하고, OCPP ctrlrs에 OCPP 메시지를 전달하는 단계, (c) OCPP 메시지에 대한 Response OCPP 메시지를 생성하여 Message Handler로 반환하는 단계, (d) 반환받은 Response OCPP 메시지를 Sending Queue에 보관하는 단계, 및, (e) Sending Queue에 보관된 Response OCPP 메시지를 상대 OCPP Entity에 전송하는 단계를 포함한다.
The present invention provides a communication method between a charging station management system and a charging station based on an OCPP in an electric vehicle charging system. According to an embodiment, a communication method between a charging station management system and a charging station based on an OCPP in an electric vehicle charging system is a method for processing an OCPP message between the charging station and the charging station management system in the electric vehicle charging system. The method comprises the following steps of: (a) receiving an OCPP message from an opposite OCPP entity and transmitting the OCPP message to a message handler; (b) checking the validity of the received OCPP message, and transmitting the OCPP message to an OCPP ctrlrs; (c) generating a response OCPP message to the OCPP message, and returning the message to the message handler; (d) storing the returned response OCPP message in a sending queue; and (e) transmitting the response OCPP message stored in the sending queue to the opposite OCPP entity. According to the present invention, efficient message transmission can be possible.
