OCPP and OCPI: EV Charging Protocols in 2025
The electric vehicle (EV) charging ecosystem relies on standardized communication protocols to ensure seamless interoperability between charging stations, central management systems (CMS), and service providers. Two of the most critical protocols in this space are the Open Charge Point Protocol (OCPP) and the Open Charge Point Interface (OCPI). While both aim to enhance EV charging infrastructure, they serve different purposes. OCPP focuses on charger-to-CMS communication, enabling remote m...
