In North America, the Open Charge Point Interface (OCPI) is a standardized communication protocol that connects Charging Point Operators (CPOs) with Electric Mobility Service Providers (EMSPs). It enables seamless data exchange across EV charging networks, allowing drivers to charge their vehicles at stations from different providers without friction.
OCPI ensures interoperability between charging infrastructure and management platforms, simplifying user authentication, billing, and session management. By fostering transparent connectivity and collaboration among industry stakeholders, OCPI supports the growth of an open, reliable, and accessible EV charging ecosystem, which is critical for the widespread adoption of electric mobility across North American cities and fleets.
