Communications

ISO 15118

Also called: Vehicle-to-grid communication interface, V2G communication interface ISO 15118 is a family of international standards for digital communication between an electric vehicle and EV charging equipment. It defines higher-level communication used for functions including charging control, identification and Plug & Charge. ISO 15118-2 is widely associated with first-generation Plug & Charge implementations. ISO 15118-20 defines second-generation network and application-layer requirements and includes message sequences for bidirectional power transfer. The standard sits on the vehicle-to-EVSE side of the system. Back-office communication between the charging station and a CSMS is normally handled separately through OCPP. J K
