The Open Charge Point Interface protocol (OCPI) supports connections between eMobility Service Providers who have EV drivers as customers, and Charge Point Operators who manage charge stations. This protocol is free to use and independent. It can work both bilateral as well as in combination with roaming hubs. Everyone can participate in the development of OCPI.
