standard way of exchanging information. Since there was no standard available this early in the industry, ElaadNL devided to start writing OCPP.

With the growing adoption and support for OCPP, ElaadNL decided to transfer OCPP to the Open Charge Alliance, a non-profit foundation under the Dutch law. The two co-founders of OCA are ESB, the Irish Utility and Greenlots, back then a US based startup in EV charging networks. The mission of OCA was stated as following:
“To foster development, adoption, and compliance of the OCA Standards and any other additional standards in connection therewith, specifically the Open Charge Point Protocol (OCPP), globally through collaboration, education, testing, and certification.”

2023 : New OCPP Test Tool & Opening of the OCPP 2.0.1 certification
In 2023 OCA and OCPP really had a substantial growth as OCPP certification has been made mandatory for government funding in both The Republic of Korea (in 2022) and in the USA (in 2023). To match this growth OCA developed a new Test Tool which is easier to use and will be able to test both OCPP 2.0.1 and 1.6 implementations (1.6 will be available in 2024).
Next to the Test Tool certification for 2.0.1 made available to keep up with the demand in the industry and the development of e-mobility.
