What is OCHP?

The Open Clearing House Protocol enables boundless electric vehicle charging across charging station networks. Using OCHP, service providers for EV charging can connect to infrastructure providers in order to provide access to their network.

Open Clearing House Protocol (OCHP) has the purpose to connect market actors in the field of electric mobility charging infrastructure. This protocol enables parties to communicate between their own back-end system (like a CMS) and a clearing house system, in a simple way.

OCHP is an open source protocol. It offers a uniform, SOAP based, interface solution. Everyone is free to implement and to actively participate in the development of the protocol, which is rapidly becoming the free international standard in the electric vehicle market. The current protocol version is 1.3.


OCHP 1.4 & OCHPdirect 0.2

After a full year of so far undisturbed productive operation of eCHS on OCHP Version 1.3, we are proud to announce OCHP 1.4. Starting with an integration phase from November 2016, the new interface will provide more functionality and higher convenience in the implementation.

At the same time, the OCHPdirect extension that was introduced with OCHP 1.3 will be updated to version 0.2 to enable further functionality and better usability for all parties.

As always, an overview of the changes can be found in the Update_Announcement.

Find the complete documentation and WSDL of Open Clearing House Protocol v1.4 on GitHub along with the OCHPdirect Extension. We are looking forward to further input from all our partners and will be hosting the next annual OCHP Workshop in February.
