Open Plug&Charge Protocol

The Open Plug&Charge Protocol (OPCP) is the worlds first protocol, standardizing the access of Plug&Charge related services. In this way, Hubject enables the discriminatory free access of the Plug&Charge Ecosystem for everyone in the industry. This will become very soon very relevant,

as the market is adopting Plug&Charge and therefore a lot of different solutions by different organisations will be in place. Therefore an open access, without lock-in effects will be needed. Publishing this protocol is for Hubject another step in enabling this.

Why Open Source?

Hubject has decided to publish this protocol as open source, because we believe that a more mature EV market requires standards and protocols, which are used by everyone. To ensure a high level of adoption, we think, protocols published under an open source agreement are the best way to achieve this and to differentiate between stakeholders with a strong believe in collaboration from others. Further information to our used open source licence can be found here

How it works

Based on this publication, everyone can use the protocol for own needs. In addition, this protocol will be used, to connect to the Plug&Charge services provided by Hubject.

In addition, we would like to get feedbacks and improvement ideas from the industry, so if you would like to support us in further developing this protocol please contact us.
