graphdefined / ocpi

The Open Charge Point Interface (OCPI) allows for a scalable, automated roaming setup between Charge Point Operators and e-Mobility Service Providers. It supports authorisation, charge point information exchange (incl transaction events), charge detail record exchange and finally, the exchange of smart-charging commands between parties.

This repostory contains the OCPI specification.
