NEFTON is a research project funded by the Federal Ministry of Economics and Climate Protection that started in 2021. Together with AVL, PEA, the Technical University of Munich, the Technical University of Deggendorf and the Forschungsstelle für Energiewirtschaft e.V. (Research Centre for Energy Economics), MAN Truck & Bus wants to analyse the system consisting of a fully electric truck, charging pole and grid connection and design it for various applications in long-distance transport. The central goal of NEFTON is the demonstration of the Megawatt Charging System (MCS) in the MAN eTruck. Recently, the project has been extended: To a charging capacity in the range of 3 megawatts. This is intended to test the newly specified MCS charging standard at an early stage.
The common goal of the project partners is to holistically research the operation of heavy goods transport based on a battery-electric truck as a solution to current and future challenges by 2024. The entire system – consisting of battery-electric truck, charging station and its network connection – is to be designed for various applications in long-distance transport. The central technical key to this is the Megawatt Charging System (MCS) with a charging capacity in the megawatt range.
The entire impact chain of the megawatt charging system will be examined for feasibility, economic efficiency and sustainability, starting with the requirements definition of commercial vehicle operators, resulting electric vehicle concepts and (fast) charging infrastructure concepts. In line with this, a highly efficient charging station in the megawatt range is being developed, which also allows bidirectional charging for a possible integration of the truck as a storage unit into the power grid.
The MCS standard is to be further researched with an extension of the project. Charging currents of 3,000A will be tested, allowing an electric truck to be fully charged in 15 minutes. For this purpose, the Technical University of Munich, together with MAN Truck & Bus and the Technical University of Deggendorf, is developing new concepts with charging capacities in the range of 3 megawatts, which will also be tested on test rigs of the new project partner Fraunhofer ISE. www.mantruckandbus.com
