Embedded Open Source Summit 2023

In this presentation you will learn how to build your own electric vehicle charger using open hardware designs in combination with the EVerest open source software stack for EV charging infrastructure. Following a quick introduction into EV charging technology, with explanations of the standards, protocols and complexities involved, the talk will go into a deep dive on how you can build your own AC charging station. Reference hardware designs for a power board, as well as a high level control board will be explained in detail. This will be followed by a comprehensive overview of the EVerest software stack and the different use-cases that can be implemented with it. Implementations of relevant communication protocols, such as ISO 15118, DIN SPEC 70121 and OCPP are integrated seamlessly. Drivers for hardware devices such as power meters and charging controllers are included as well. Additionally, comprehensive tools for simulating the charging process are provided. EVerest is an Apache 2.0 licensed project within LF Energy. It was initiated by PIONIX GmbH to support the electrification of the mobility sector. The hardware designs presented in this talk are CERN Open Hardware Licence Version 2 - Permissive licensed, initially developed by PIONIX GmbH as well.
