MAN Truck & Bus conducted a public demonstration of megawatt charging for heavy electric trucks in sub-zero conditions in Norrköping, Sweden, charging an eTGX at approximately 750 kW using the Megawatt Charging System (MCS). The test is part of MAN’s work to demonstrate interoperability between trucks and chargers, a prerequisite for scaling high-power charging beyond pilots.
According to the demonstration, megawatt charging can bring the eTruck from 10% to 90% in around 30 minutes, potentially aligning with a standard break, provided sufficient site power is available.
The manufacturer says its eTGX and eTGS models can already be ordered with the MCS option, with series production of the MCS equipment variant due to start in Q2 2026. For fleets, this provides a clearer timeframe for when MCS-ready vehicles will move from demonstration units to standard build slots.
The charging session took place during Kempower’s “MCS Live Winter Days” at the depot of Alfredsson Transport AB, a Swedish operator that has positioned its site as a publicly available charging hub for heavy-duty vehicles. According to Kempower, the depot has 12 charging points designed for combinations up to 34 metres, with charging power from 400 kW to 1.2 MW.
The depot’s energy setup also illustrates the infrastructure challenge behind megawatt charging. Kempower says the site has a 2.4 MW grid connection, supported by 2.4 MWh of battery storage and a 400 kW solar system; a configuration aimed at managing peak demand and reducing energy costs.
MAN’s Program Lead Charging, Sven Steckhan, said the Swedish sessions demonstrated “controlled charging performance and secure communication between vehicle and charger”, adding that testing confirms the robustness of the hardware and software integration for series production.
The event also highlighted what operators are likely to face during the early rollout phase: the industry expects a gradual transition in which both CCS and MCS will be needed, while grid capacity limitations remain a key constraint on wider deployment, particularly outside the Nordics.
