About us : Promoting Open Standards - Connecting the EV Industry

The Open Charge Alliance (OCA) is a non-profit organisation founded in 2014. With members from all over the world we focus on open standards and improving the development of sustainable charging.

Our mission is to foster global development, adoption, and compliance of communication protocols in the EV charging infrastructure and related standards through collaboration, education, testing, and certification. The OCA reinvests the fees collected from members and companies purchasing OCTT to advance the development and spread of OCPP and other open standards.

With more than more than 350 members from all over the globe, we span all sectors of the industry, including charging equipment manufacturers, software and systems providers, charging network operators, and research organizations.
