Finnish electric vehicle (EV) fast-charging specialist Kempower has successfully demonstrated its Megawatt Charging System (MCS) in demanding sub-zero temperatures in Sweden. The company hosted three major European commercial vehicle manufacturers for its MCS Live Winter Days event, held in January and revealed this week.
Industry Leaders Convene for MCS Demonstration
German manufacturer Man Truck & Bus, along with Swedish providers Scania and Volvo, participated in the event. The gathering aimed to validate the readiness and reliability of MCS technology for heavy-duty electric transport, even under extreme weather conditions.
“Our aim with this event was to demonstrate that MCS is live and here to stay,” stated Antti Vuola, VP of products at Kempower. “More importantly, we wanted to bring together the key actors in the industry to highlight the importance of collaboration in advancing the further deployment of MCS for heavy-duty electrification.”
State-of-the-Art Charging Hub Underpins Trials
The testing took place at Alfredsson Transport AB’s truck depot in Norrköping, Sweden. This facility, which has operated a fully fossil-free fleet since 2015, is notable for hosting the world’s first known real-life charging session utilizing the official MCS charging communication protocol in August 2025, charging a Scania truck with a Kempower MCS charger.
As Sweden’s first MCS truck charging hub, the Alfredsson Transport depot features 12 charging points specifically designed for heavy-duty vehicles up to 34 metres in length. The setup, entirely built with Kempower’s hardware and charging management software, delivers charging power ranging from 400 kW to 1.2 MW.
The depot’s infrastructure includes a 2.4-megawatt (MW) grid connection and 2.4-megawatt-hours (MWh) of battery storage, enabling cost optimization per kilowatt-hour (kWh). A 400 kW solar system further supplements the depot’s energy supply.
Manufacturers Confirm MCS Maturity
Man Truck & Bus, Scania, and Volvo each brought their MCS-ready trucks to the event to showcase the charging capabilities with Kempower’s MCS charger.
Man Truck & Bus presented one of its eTGX battery electric trucks, which currently supports charging capacities of up to 750 kW. Equipped with a battery capacity of up to 480 kWh, the eTGX offers a driving range of approximately 500 kilometres. A charging stop of just 45 minutes at an MCS charger can reportedly add around 350 kilometres of range.
“The MAN eTruck has proven the stability of the MCS charging process during the live demonstrations in Sweden, including controlled charging performance and secure communication between vehicle and charger,” commented Sven Steckhan, program lead charging at Man Truck & Bus. “All our tests confirm the robustness of hardware and software integration and underline the maturity of MCS technology for future series production.”
