Keynote: From Ambition to Reality: How We Built the Global Open Source Community Around EVerest - Marco Möller, Co-founder and CEO, Pionix GmbH

Creating a successful open source project is about more than just code—it's about building a thriving, sustainable community. In this talk, we’ll dive into how the EVerest project—an open-source operating system for EV charging infrastructure—has evolved from an ambitious idea into a global collaboration.

We’ll share what it takes to grow an open source ecosystem in a hardware-centric, standards-heavy domain like electric mobility. Drawing on our journey at PIONIX and real-world experiences working with suppliers, OEMs, and developers along the EV charging supply chain, this session will focus on the strategic and collaborative side of open source: governance, contribution models, ecosystem incentives, and how to create long-term value for everyone involved.

Expect candid lessons, practical frameworks, and stories from the trenches of building a mission-driven open source community—because innovation happens when we build together.

- Quick EVerest update
- Building a healthy contributor community in a commercial-industrial context
- Aligning corporate goals with community needs
- Creating pull along the supply chain through open source collaboration

EVerest is LF Energy’s open source software stack built to power the next generation of EV chargers. Designed with manufacturers in mind, it simplifies integration of industry standards (like OCPP, ISO 15118, and Plug & Charge), improves interoperability, and accelerates time-to-market — all while offering the flexibility of a modular, community-driven approach.

Whether you build AC wallboxes, DC fast chargers, or specialized commercial solutions, this session will show how EVerest can help you streamline your development, reduce engineering costs, and deliver more reliable products to your customers.

Abstract:
Bidirectional charging is transforming electric vehicles into active participants in the energy system, enabling energy flows between vehicles, charging infrastructure, and the grid. This talk will examine the entire impact chain of bidirectional charging, from the vehicle to the grid, and focus on how protocols such as EEBUS, OCPP, and ISO 15118-20 facilitate communication and energy management within this process. We will explore the key challenges and gaps in this ecosystem and discuss strategies for addressing them. EVerest, an open-source EV charging stack, will be highlighted as a solution for integrating these protocols to enable efficient and interoperable charging solutions. Join us to discover how open standards and innovative strategies are driving the future of bidirectional charging and energy management.

One of the reasons why people are hesitant to buy an EV is because of the inadequate availability of charging stations. Incompatibilities between charging stations and electric vehicles lead to a fragmented industry with many protocols and interpretations. Governments are trying to fix that by standardizing around Tesla technologies, but the problem remains. LF Energy-hosted open source project Everest aims to provide a reference implementation for all protocols in the EV charging industry, covering communication to the car and cloud, to simplify and standardize the charging process. In this interview, Piet Gömpel, Tech Lead at Pionix, talks about the work the company and the community is doing around this problem. He strongly feels that participation by EV makers like Tesla will boost the adoption of such standardized technologies.

This session will provide a general overview of how DC charging works, starting with a basic block diagram of a DC charger. It will then explore how to use YETI/YAK dev kits for a basic DC charger prototype, and move into how to configure LF Energy EVerest for DC charging.

A robust and interoperable charging network is key to increasing electric vehicle (EV) adoption, and by extension, to achieving the transportation decarbonization goals of the United States. To ensure reliability and interoperability in software, the U.S. Government has, in the Code of Federal Regulations, section 680, established minimum standards for the charging software stack. The Joint Office of Energy and Transportation (JOET), through the Applied Interoperability (AI) project, is partnering with stakeholders to create an open-source reference implementation that meets these federal minimum requirements. The reference implementation can provide a focal point to work together to implement complex standards consistently. It can also provide a mechanism to disseminate innovative power management monitoring and control techniques into production and increase vehicle to grid integration. This session will outline JOET and AI goals, highlight how they can be achieved using an open-source reference implementation, and issue a call to action to join the broader community around open source software for EV charging.

Speaker: Dr. K. Shankari, US Joint Office of Energy & Transportation

This session will explore how the US Joint Office of Energy & Transportation's Applied Interoperability Project will ensure:
-Any PEV owner can safely plug in anytime and anywhere and be dispatch-able as a 'certified resource’
-That helps electric system operators maintain reliable service while achieving our State RPS and GHG reduction goals
-Seamlessly without confusing the consumer
-Or impacting their transportation needs
-In a way that lowers their total cost of ownership
-Any actor can contract and settle with any other
