OCPI

Also called: Open Charge Point Interface OCPI, the Open Charge Point Interface, is an open protocol for exchanging EV charging data between Charge Point Operators, e-mobility service providers and roaming platforms. It supports information such as locations, availability, tariffs, authorisation, sessions and Charging Detail Records. OCPI solves a different interface problem from OCPP. OCPP usually connects charging equipment to its management system. OCPI connects the organisations and platforms that need to exchange charging and roaming information. The current OCPI version is 2.3.0. It adds support for data required by EU National Access Points under AFIR, along with direct-payment functions, Plug & Charge indication and extensibility.
