The Open Charge Alliance is a formed industry alliance of EV charging hardware and software vendors, and charging network operators and service providers. OCA’s mission is to foster global development, adoption, and compliance of the Open Charge Point Protocol (OCPP) and related standards through collaboration, education and testing.
Frequently asked questions
OCA was formed to continue and extend the work of the OCPP Forum, adding an international dimension, stronger organizational structure, and capabilities for protocol compliancy and formal certification.
OCA’s Originating Members are E-Laad, the EV charging network operator launched by a consortium of Netherlands DSOs (utilities); ESB, the Irish national utility; and Greenlots, a North American vendor of open standards-based EV charging solutions. In 2015 the board has grown with two new members: RWE, an electricity and gas company and G2 mobility an electric vehicle (EV) smart charging solutions company specialized in energy optimization.
The Open Charge Alliance is focused on the development of the Open Charge Point Protocol (OCPP) and Open Smart Charging Protocol (OSCP), including the upcoming publication of OCPP v2.0 and OSCP v1.0 Specification and compliancy and certification services. OCA is also promoting and informing stakeholders about OCPP and OSCP worldwide, and developing Alliance membership services and market/business value.
OCA provides members with the opportunity to help shape current and future versions of OCPP to meet their market and product requirements. By leveraging the technical expertise, market intelligence, and industry leadership of its members, OCA can help drive the adoption of open standards and deliver low-cost, interoperable and universal EV charging infrastructure. The ultimate goal of OCA is to provide a superior experience for drivers, site owners, network operators, and the entire EV industry.
The specification for OCPP v1.5 was published in 2012 and is being used in multiple charging networks today. In 2015 OCA has published a Release Candidate of OCPP 1.6 and work has started on finalizing 2.0 in 2016. OCA has released in 2016 the Compliance Testing Tool for OCPP 1.6.
The three Originating Members (E-Laad, ESB, Greenlots) comprise the OCA Board at present. In 2015 the board has grown with two members: G2 mobility (France) and RWE (Germany).
