The Open Charging Network allows very efficient roaming between CPOs (Charge Point Operators) and eMSPs (emobility Service Provider). Whilst the pure P2P connection via OCPI (Open Charge Point Interface) is complex and therewith time and money consuming, the OCN allows to connect to all players just with one connection.
The OCN is curated by the non-profit Share&Charge Foundation. eMobilify is main contributor to the OCN. The Foundation has got strong members like innogy SE, EV Box, Elaad, Volkswagen Financial Services and leading scientific institutions.
