During an extensive test drive, development engineers from Mercedes-Benz Trucks evaluated the performance of the Megawatt Charging System (MCS) with the new eActros 600. The test drive, which took place earlier this year, covered approximately 2,400 km and traveled from Germany through the Netherlands, Belgium, and Denmark to Sweden. The aim was to verify the compatibility between the vehicles and the MCS charging stations from various manufacturers, as well as to test the practicality of charging under winter conditions.
The test vehicles were charged at various charging stations, both public and private. One eActros 600 also underwent additional winter tests in the Finnish Arctic Circle, where temperatures dropped to –20 °C, before beginning the return journey.
Insights from the Test Drives
Peter Ziegler, Head of E-Charging Components at Mercedes-Benz Trucks, explains the key insights from the tests. These provided important information on battery thermal management and interoperability between the vehicle and charging infrastructure. The tests confirmed that charging powers in the megawatt range are possible even at low temperatures, provided the battery maintains an adequate operating temperature. This is particularly relevant, as megawatt charging typically occurs during legally mandated driving breaks, ensuring operational capability in real-world conditions. Additionally, successful charging operations were conducted at several charging points, demonstrating the practicality of the system.
Potential of Megawatt Charging
Mercedes-Benz Trucks sees megawatt charging as a central role in the electrification of heavy long-distance transport and supports the MCS standard as an open, cross-manufacturer solution. Given the dynamic developments in the market for battery-electric commercial vehicles, a uniform, internationally compatible charging standard is increasingly deemed important. The MCS standard aims to promote interoperability, scalability, and investment security across various markets and manufacturers.
Next Steps for Finalizing the MCS Standard
The ongoing finalization of the MCS standard encompasses both the hardware and software of the vehicles as well as that of the charging infrastructure. In the coming months, Mercedes-Benz Trucks plans further tests for interoperability with various charging station manufacturers to further optimize the interaction between vehicle and charging infrastructure.
Additionally, Daimler Truck is participating as an industry partner in the project „HoLa High-Power Charging in Truck Long-Distance Transport“ and will test the eActros 600 in high-power charging infrastructure in real operations throughout the year. In the second half of the year, the first customer trials of MCS-capable eActros 600 in real logistics operations are planned. These vehicles are to be used as part of the project to electrify the transport logistics of the German Mercedes-Benz Trucks production plants „Electrify Inbound Logistic“ at various customer sites. To reduce the charging times of the electric trucks, an MCS-capable charging station is also planned on the factory premises in Wörth am Rhein, which is expected to be operational by mid-year.
