Information
Definition
Open Charge Point Protocol (OCPP) is the open protocol used for communication between EV charge points and charging station management systems. It supports authorisation, transactions, remote monitoring, diagnostics, smart charging and interoperability between hardware and backend platforms.
Why it matters
It matters because OCPP support strongly affects backend choice, charger migration, software integration, operational control and long-term support for UK public, workplace and fleet charging networks.

EN 63584
EN IEC 63584 is the European and international standards-track home for OCPP, formalising Open Charge Point Protocol communication between charge points and charging station management systems. In UK terminology it supports OCPP as a recognised interoperability standard for EV charging infrastructure.
