OCPP Overview

What is OCPP

OCPP is simply a syntax (language) used to communicate between a networked charging station and a network management system such as ChargePoint. Open Charge Point Protocol (OCPP) was defined by an informal group known as the OCPP Forum led by two companies from the Netherlands.
++ The OCPP Forum has over 50 members. ChargePoint has been an active member of the OCPP Forum for many years.
++OCPP is not copyrighted and is freely available for use by anyone at no cost.
++OCPP has evolved over the last 5 years from its initial release to Version 1.2, which was the first version to be deployed in production charging stations, and then to the current Version, 1.5.
++OCPP Version 2.0, is a work in progress, that further expands functionality and is currently undergoing a review process prior to its expected release in 2014.

Benefits and Impacts of OCPP

“In simple terms, achieving such interoperability relies either on a proprietary standard or on an open standard. The main difference between these two types of standards is that open standard movement aims at establishing industry-wide or nationwide interoperability among its stakeholders by preventing the rise of any monopolistic power in functioning the interoperability”.5
Some of the main advantages of OCPP are:
 Support a charge point owner to change network operator when it wants, thus preventing the charge station assets from being stranded.6 7
 Allow the common communications between charge station and network service provider to be also leveraged for providing grid services (e.g., demand response) cost effectively.
 Encourage customers to own EVs by enabling uniform access to charging stations, roaming and billing services.
