Last week, an electric truck was publicly charged for the first time with over 1000 kilowatts and 1500 amps. Enough to give the 40-tonne long-distance eTruck from MAN a driving range of around 400 kilometers in 30 minutes. The charging premiere was part of the presentation of the results of the NEFTON research project launched in 2021. In the project, which is funded by the German Federal Ministry for Economic Affairs and Climate Protection, MAN Truck & Bus and the Technical University of Munich (TUM) as well as five other partners from science and industry have analyzed the system consisting of an all-electric truck, charging station and grid connection and designed it for various application scenarios. The focus is on the Megawatt Charging System (MCS) for ultra-fast charging of electric trucks during the driver’s break or when loading and unloading at the ramp.
Prof. Markus Lienkamp from the Chair of Automotive Engineering at TUM, who is leading the NEFTON project consortium, explained: “The scientific facts speak for themselves: battery electric trucks have an efficiency of around 75%. Fuel cell trucks with an efficiency of only 26% and eFuels with an efficiency of just 14% are miles away from this. However, the infrastructure on the main traffic routes is still lacking for the actual effective use of electric trucks. Megawatt charging technology is a huge step forward in this respect.”
NEFTON analysis: Need for public charging infrastructure
Based on the analysis of real-life deployment scenarios from four freight forwarders, NEFTON’s research results clearly show the importance of public fast-charging infrastructure for the sustainable drive transition: While it is already possible to electrify transport in regional and distribution operations using the logistics centers’ own charging infrastructure, an effective conversion of long-distance transport requires fast-charging stations with up to one megawatt of charging power every 50 km along the core routes of the freeway network. Charging capacities of up to 3000 kW, as also investigated by NEFTON, can even further increase the efficiency and flexibility of electric trucks for long-distance transportation. NEFTON has also already looked at bidirectional charging for possible integration of the truck into the power grid as storage for more efficient use of the electricity supply during the day. In addition to MAN Truck & Bus and TUM, the research consortium also includes Deggendorf Institute of Technology, Fraunhofer ISE, Forschungsstelle für Energiewirtschaft e.V. (FfE), AVL Software and Functions GmbH and Prettl Electronics Automotive.
MAN’s commitment to expanding the infrastructure
In addition to projects such as NEFTON, MAN is also involved in the area of charging infrastructure. At the beginning of July, a partnership was launched with energy provider E.ON to set up around 400 charging points at around 170 locations across Europe. With around 125 locations, this will also create the largest public commercial vehicle charging network in Germany to date. As part of the TRATON Group, MAN is also involved in the Milence joint venture together with Daimler Trucks and AB Volvo, which is gradually building at least 1,700 commercial vehicle charging points in Europe. MAN also has charging infrastructure and corresponding consulting services in its portfolio for its customers through cooperations with partners.
