MAN Truck & Bus and ABB E-mobility have successfully completed a landmark week of testing for the next-generation Megawatt Charging System (MCS), a critical technology for the electrification of heavy-duty transport. The comprehensive tests validated the system’s performance, safety, and interoperability between the electric truck and the charging infrastructure.
Key Highlights
- Rapid Charging: An electric truck battery with a 480 kWh capacity was charged from nearly empty to 90% in under 40 minutes.
- High Power Delivery: The system supported an extended charging session at a steady 1000 A, reaching a peak power of 740kW.
- Advanced Safety: Emergency shutdown tests showed the current was reduced from 1000 A to 0 A in less than 3 milliseconds, far exceeding the required safety standards.
- Proven Stability: A continuous charging session was completed over 3.5 hours without any interruption, demonstrating the platform’s reliability.
- Low Operating Temperatures: During a long, high-current session, the charging pin temperature never exceeded 55°C, remaining well below the 100°C standard limit.
Importance of Interoperability Testing
As the heavy-duty trucking industry transitions to electric powertrains, ensuring seamless interoperability between trucks and charging stations is a primary challenge. Any incompatibility could lead to operational disruptions, increased costs, and a slowdown in the adoption of sustainable long-haul transport.
These tests are essential for building confidence in the technology. Christopher Thompson, Head of Product and Portfolio Marketing at ABB E-mobility, noted that the validation proves an electric truck can charge efficiently and safely without losing valuable time. According to Marcel Hessel, responsible for Charging Systems & Components at MAN Truck & Bus, the test confirmed that MCS technology is ready to deliver the necessary performance while meeting the highest safety standards, which is critical for customers who cannot afford downtime.
Building on a Strong Partnership
This test week marks a significant milestone in the research and development partnership between MAN and ABB E-mobility. Both organizations have been key contributors to the development of the global MCS standard, aligning their technology roadmaps to ensure vehicles and infrastructure work together flawlessly. Prior to these tests, the companies conducted joint interoperability checks, set up two fully functional MCS systems, and validated long-duration sessions.
Setting the Industry Standard
The Megawatt Charging System is widely regarded as a cornerstone technology for achieving zero-emission heavy-duty transport. This joint testing demonstrates how collaboration between vehicle and infrastructure manufacturers can accelerate technical readiness. The successful results provide operators with the confidence needed to transition to electric long-haul logistics, proving that the future of heavy-duty charging is interoperable, safe, and reliable.
