“This CharIN Testival marks a major step forward. The strong focus on Megawatt Charging andVehicle-to-Grid shows that interoperability is moving beyond concepts into real, scalablesolutions for both e-mobility and power systems. By bringing together OEMs, infrastructureproviders, grid experts, and technology partners in a hand-on environment, we accelerate trust,technical alignment, and real-world readiness. This collaboration shows how interoperabilityenables reliable, scalable, smart charging for the future.”Mariia Andreeva, Executive Board at CharIN
The CharIN Testival featured:
- 200 attendees participated in the event
- 145 testers and 55 public day participants
- 15 charging stations
- 8 AC/DC test systems
- 6 heavy-duty vehicles
- 4 electric vehicles In 9 testing slots throughout the 3 days
“The Megawatt Charging System(MCS) represents a major step forward in enabling long-haul electric transport at scale. At Milence, we recognize its potential, which is why we are already deploying MCS along key transport corridors. Scaling this technology requires close collaboration across the ecosystem. Through the CharIN Testival EUROPE 2026, hosted at our Interoperability Lab, we are providing a platform to validate the performance of MCS technologies in real operational conditions. This kind of collaborative testing is essential to ensure interoperability, reliability, and readiness for widespread adoption.”Maarten Jaspers, Chief Operations Officer at Milence
“Electric vehicles are becoming an increasingly integral part of the energy system. This makes interoperability and Vehicle-to-Grid testing more important than ever. At ElaadNL, we see this Testival as a unique opportunity to test and improve the latest charging technologies, support their integration into the grid, and share practical insights that contribute directly tointernational standardization."Thijs van Wijk, manager at Elaad Test

V2G and MCS: driving interoperability in e-mobility
The CharIN Testival EUROPE 2026 highlighted the transformative potential of Vehicle-to-Grid (V2G) and Megawatt Charging System (MCS) technologies to create a sustainable, interconnected e-mobility ecosystem. The event brought together main players in the industry for rigorous interoperability testing, performance validation, and standardization discussions, key steps toward accelerating the adoption of these solutions. Both AC and DC bidirectional power transfer were actively tested. For AC use cases, EV and EVSE prototypes and test systems were available for the first time to test AC distributed energy resource services based on ISO 15118-20 amendment 1, supporting a subset of grid support functions. For DC use cases, a commercial heavy-duty vehicle supported bidirectional power transfer in combination with MCS. The trend toward V2G support is reflected in the test landscape. 13 out of 23 DC test devices supported bidirectional power transfer, and 7 out of 11 AC test devices supported AC bidirectional power transfer or AC bidirectional power transfer distributed energy resource functions in line with ISO 15118-20 and amendment 1. While vehicle-to-grid implementations and or EU grid codes compliance tests remain at an early stage of maturity, the event represents a strong step forward compared to previous CharIN Testivals, further strengthened by the availability of grid emulation systems, which enabled more realistic and controlled testing environments
Moreover, MCS testing attracted significant interest, with a record of 4 heavy-duty vehicles, 7 EVSEs, and 4 test systems supporting MCS services, primarily focusing on high power charging via ISO 15118-20 amendment 1 and TLS 1.3 support. One identified area for improvement was compatibility and line lock reliability of the MCS coupler and inlet standardization, referencing IEC TS 63379, further underlining the importance of continuous alignment within CharIN’s standardization and testing ecosystem.
