The complete solution for communication with charging infrastructure and electric vehicles
倍福的 TwinCAT IoT 产品系列增加了基于 WebSocket 的 IoT 通信,支持开放充电协议(OCPP)。OCPP 规范了电动汽车充电桩与相应的中央管理系统之间的通信。它可与符合 IEC 61851 和 ISO 15118 标准的新型 EtherCAT 通信接口端子模块 EL6761 结合,构成一个通用的充电基础设施通信解决方案。
随着最新的 TwinCAT 3 IoT OCPP(TF6771)功能的推出,通过 C++ 驱动程序可以实现 OCPP,并封装为 PLC 功能库。考虑到市场需求,倍福首先推出的是 OCPP 1.6 和 2.0.1 版本。重点是以下两个用例:
EL6761 单通道通信接口还提供两个选项:EtherCAT 端子模块可用于实现充电基础设施与电动汽车以及上层充电管理系统之间的通信。此款端子模块支持符合 IEC 61851 标准的 PWM 通信和符合 ISO 15118 标准的电力线通信这两种完全独立的通信标准。后者具有灵活的通信通道,可用于实现汽车与充电站之间的数据传输。
The Open Charge Point Protocol (OCPP) is added to the IoT product portfolio based on the WebSocket protocol. OCPP standardizes the communication between charging stations for electric vehicles and the associated central management systems (CSMS). OCPP versions 1.6 and 2.0.1 are used here on account of their market relevance.
The EL6761 EtherCAT Terminal enables communication for the charging infrastructure both to the EV (Electric Vehicle) and to the higher-level charging management system. It supports two completely independent communication standards: PWM communication in accordance with IEC 61851 and powerline communication as stated in ISO 15118. ISO 15118 communication provides a flexible communication channel for transporting all necessary data between the car and the charging station. In combination with OCPP (TF6771) as communication to higher-level controllers, this results in a complete communication system for charging infrastructure applications.
