We introduce Tux-EVSE, an open-source suite of embedded software components for building a complete Electric Vehicle (EV) charging system using readily available hardware on Linux. Tux-EVSE is designed with a strongfocus on security and ease of integration, utilizing a lightweight microservice framework (AFB) that isolates components for flexible development and testing. This modular structure allows developers to efficiently test and refine each component on a local machine before deploying to the final embedded hardware. The framework also embeds a security layer so that fine-grained permissions can be requested and granted to the application and / or services.

Written primarily in Rust, Tux-EVSE supports modern EV charging protocols, including ISO 15118-2x, DIN SPEC 70121, SLAC, and OCPP.

We will detail the different components of the charger: which kind of hardware components it can use, how the charging logic is implemented and how the modular architecture could allow one to adapt the charger to ones needs.
