Mercedes-Benz Trucks conducted a 2,400-kilometer endurance test with two eActros 600 trucks compatible with the Megawatt Charging System (MCS). The aim was to evaluate megawatt charging under real operating conditions, using public and private infrastructure dedicated to heavy-duty vehicles.
The route connected the factory in Wörth-am-Rhein, Germany, to Linköping in southern Sweden, passing through the Netherlands, Belgium, and Denmark. Engineers analyzed the compatibility of the vehicles with MCS stations from different manufacturers, as well as charging performance, including in winter conditions.
"The main challenges of megawatt charging lie in harmonizing the vehicle with different charging systems. High currents also place high demands on thermal management," explains Peter Ziegler, Head of Electric Charging Components at Mercedes-Benz Trucks. "This test allows us to evaluate these aspects in the field."
MCS technology allows charging powers of up to 1,000 kW. This means that the eActros 600 can recharge its batteries from 20 to 80% in around 30 minutes, saving time compared to current CCS charging. This is an advantage for long-distance transport operations, subject to the availability of infrastructure.
Developed under the impetus of CharIN, the MCS standard aims to facilitate the deployment of a pan-European fast-charging network for electric trucks. Although there are still few stations in Europe, these trials are helping to prepare for their large-scale use.
