Accelerating the Future of Heavy-Duty Charging with Megawatt Charging System
PUBLISHED
A milestone for Megawatt Charging System development
CharIN’s Megawatt Charging System (MCS) journey continued with the Testival in Saint Genis-Pouilly, the first event dedicated to advancing high-power charging for heavy-duty transport. Hosted by ADVANTICS, this three-day event brought together testing experts, EV and charging system manufacturers, and key stakeholders to push forward the next generation of interoperable charging solutions.
After a successful CharIN MCS Controller Testival at AUTEL Energy Europe, this latest CharIN Testival is now focused on fully integrated MCS testing, bringing four heavy-duty vehicles into the signature testing process.
This was full MCS system integration in action. For the first time, power transfer was successfully tested with real vehicles and charging systems. Participants were able to mutually authenticate charging sessions using the mandatory mutual TLS 1.3 security mechanism, marking a first step toward a more secure and seamless Plug and Charge integration in compliance with the ISO 15118-20 standard. This advancement paves the way for a future-proof, interoperable, and secure charging ecosystem.
Megawatt Charging System in action
The highlight of the event was the Public Day on June 4th, which offered visitors a deep dive into real-world MCS controller testing and implementation. This day attracted a broader audience from across the e-mobility value chain, including business developers, media representatives, and industry decision-makers eager to witness the latest progress in MCS.
The day began with opening words and a welcome from Patrice Dunand, President of Pays de Gex, who attended setting the tone for collaboration and innovation. Attendees then joined a guided CharIN Testival tour led by CharIN’s CTO Michael Keller, who walked participants through the full testing environment, showcasing how heavy-duty vehicles, charging systems, and communication protocols came together in real-world conditions. One of the standout moments was the live MCS charging demonstration hosted by ADVANTICS in collaboration with Stäubli, featuring their MCS connector in action.
Visitors were also able to explore how an MCS station is built from the ground up and learned more about secure charging through sessions on Multi-PKI authentication and V2G applications for commercial vehicles.
The day concluded with a strategic deep dive into the “Why, What, and How” of Plug and Charge, led by Strategic Testing Partner Hubject. This session tied everything together by highlighting the critical role of secure, standardized communication for the successful rollout of megawatt charging worldwide.
CharIN: Leading the Global MCS Rollout
Since 2018, CharIN has led the development of the Megawatt Charging System (MCS), building on existing CCS (Combined Charging System) standards. Through its MCS Task Force, CharIN brings together industry leaders to drive innovation and establish a unified global standard for high-power charging.
Continuing the development journey from the CharIN MCS Controller Testival at AUTEL Energy Europe, CharIN has now stepped up to full, integrated MCS testing by bringing four heavy-duty vehicles into its signature testing process. This achievement underscores CharIN’s sustained dedication to real-world validation and practical implementation of MCS technology. As part of this ongoing initiative, Scania is scheduled to showcase MCS equipped trucks at the upcoming EVS38 event in Gothenburg, exemplifying CharIN’s leadership in guiding the industry’s progression from ISO standardization efforts, specifically ISO 15118-20 and related protocol, to large-scale deployment of interoperable and secure MCS solutions globally.
Industry Voices
Patrice Dunand, President from Pays de Gex attended the Public Day and quoted:
"We are proud to welcome this international event to the Pays de Gex. It is a strong signal of our support for electric mobility and our ambition to position the region as a major player in innovation. By bringing together manufacturers, experts, and constructors to test, exchange, and move forward on interoperability, this event fully reflects our identity, where technological excellence, local roots, and conviviality come together."Michal Elias, founder of ADVANTICS added:
“Hosting the CharIN Testival is a proud moment for us at ADVANTICS. We are excited to test the market-ready MCS charge controller against real-life trucks. The future of megawatt charging is here.”We were proud to host this year’s CharIN Testival at our headquarters, where real-world MCS testing marked a key step forward for high-power charging. We hope all participants enjoyed the experience and left inspired by the progress made across the e-mobility ecosystem.
