OCPI basics

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.

OCPI aims to:

  • accelerate the market for EV drivers
    A mature EV market needs a single communication infrastructure where all market players in the EV and energy sector are connected. New, integrated and profitable business models can be developed that provide flexibility and assure continuity of supply.
  • improve mobility services
    EV-drivers may expect to have an optimal user experience, regardless of borders, operators or equipment. Prices, tariffs, locations, availability and a single invoice should be available real-time in a transparent way.

The goals of OCPI are to simplify, standardize and harmonize.

Usage

OCPI is used worldwide and adopted by many companies and several roaming hubs. Many organisations use it in a hybrid way for both peer to peer connections and in combination with hubs like GIREVE and e-clearing.net.

The use of an independent open roaming protocol like OCPI is also demanded in many public tenders in Europe and USA.
