In response, PIONIX has developed a project called EVerest, an open-source software stack designed to establish a common base layer for a unified EV charging ecosystem. EVerest has gained some serious cred in the developer world, with its biggest support LF Energy (the Linux open-source foundation for the power systems sector). I spoke to the project’s brainchild, Dr. Marco Möller, managing director of PIONIX, to find out more.
What’s the problem with EV charging software?
The idea for EVerst came from Marco Möller’s previous startup, German commercial drone software firm MAVinci (Intel acquired the company in 2016). Möller shared: After the initial founder team left Intel in 2020, they did consulting work with charging manufacturers and found that many engineers were involved in “me too” projects, effectively replicating the same code, even though 99% of the code was already engineered. Shared open source implementations are vital to mitigate the differences in charging standards globally from CHAdeMo, commonly used by Japanese automakers, to China’s ChaoJi, and CCS, popular in Europe and the US. Further, every car is slightly different, making it even more urgent to have an open-source solution for the chargers. An open tech stack means developers can focus on more exciting work and bring products to market faster.
The EVerest EV charging solution
Möller explained that the project had received interest from various players in the EV charging space, except for a few big proprietary players, noting: The EVerest software platform runs on a lightweight Linux system inside the charging point. It manages communication around energy between different players:
Car (e.g., EN IEC 61851, ISO 15118) Local energy generation & batteries (e.g., Modbus, Sunspec) Grid (including specific grid constraints) Cloud backend / payment (e.g. OCPP 1.6) The user (interface)
EVerest digitally abstracts the complexity of multiple standards and use cases. This means it can run on any device, from AC home chargers to public DC charging stations. This helps facilitate new features for local energy management such as local energy management, PV integration, and initiatives like wind and solar-powered EV stations and bi-directional charging.
What about the elephant in the machine: security?
There’s been a lot of research about the challenges of securing EV chargers, especially preventing hackers from using them for over or undercharging, committing identity fraud, or damaging the grid. Vulnerabilities in open-source libraries have increasingly become an attack vector. The insertion of malicious code being inserted into packages in repositories (for example, npm and PyPI) is rising, and the recent Log4j zero-day exploits demonstrate the challenge of code maintenance in open source projects. However, having a project under the auspices of The Linux Foundation is an advantage. It especially helps lend credibility increases the number of people working on the code. Möller noted: The project is also liaising with the hacker enthusiast community to participate in hackathons over the summer months hopefully. As Marco asserts, “these people who break systems for fun.” The team is also raising venture capital, which will go into developing and improving the open-source codebase. In short, EVerest welcomes the global community to contribute to this project. Visit the project on GitHub and subscribe to the EVerest general mailing list.
