Monthly Developer Community Calls are being hosted to align the development of all Open Charging Network software components.
Anyone is invited to jointly discuss current status of development, upcoming releases, development contributions from the community, and other related topics.
Calls will take place every second Tuesday of the month via the video conferencing platform Zoom. The call will be recorded and published on this page.

The development of the Open Charging Network is steered by community needs with the non-profit Energy Web Foundation curating the development.
For this purpose, transparency about the current feature set is required, which the following OCN maturity model (inspired by Gitlab) shall provide. The maturity model and the roadmap of the Open Charging Network development is discussed quarterly during the Share&Charge Foundation and Tech Call.
The maturity model is based on different categories (columns):
Messaging: How messages between OCN Parties are transmitted and secured
Service interfaces: Interfaces that can be used by OCN Parties to connect their services to the OCN
Connection & Community: Tools for the community to test and use the OCN
Maturity is indicated with different-sized black boxes or a heart:
A reference to the open source repositories is provided in parenthesis after the feature description.

The development of the Open Charging Network is driven and steered by the non-profit Energy We Foundation. Many users and community members are contributing to it in the form of feedback, raised issues, pull requests and dedicated working groups. This article should provide you with some guidance on how you can contribute to this project.
The production-ready version of every Open Charging Network component can be found in its MASTER BRANCH
Development of each component can be found in its DEVELOP BRANCH. Pull requests should therefore generally derive from the develop branch, which will be eventually merged into the master branch to coincide with the release of a new version.
Bare in mind that new features that are big enough may warrant their own feature branch so that multiple contributors can work on them before being merged into the development branch.
Before we can include your contributions to the Open Charging Network code, you need to give us permission. As the author of any creative work (including source code, or documentation), you control the copyright for that work. Energy Web Foundation Foundation can’t legally use your contribution unless you allow us to.
Please take the following steps so that we can include your work:
Your sign-off certifies that you are either the author of the contribution or have the right to submit it under the Apache 2.0 license used by the Share&Charge project. The sign-off is done by adding the following line to your source code:
You must use your real name. Pseudonyms or anonymous contributions are not allowed.
If you set your user.name and user.email as part of your Git configuration, you can sign your commit automatically with git commit -s.

Planned: Requirements are getting defined
Minimal: First implementations are tested
Viable: Can be used in production
Lovable: Functionality set is complete and used by community

The Open Charging Network is a community project by and for the Electric Vehicle Charging community. Its mission is to provide the EV Charging industry players an open, secure and decentralized network for digital interoperability. This is why the core components are developed open source under the .
