PEM Develops Modular Powertrain for E-TrucksCopyright: © PEM RWTH Aachen
In the "SeLv" project, the chair "Production Engineering of E-Mobility Components" (PEM) of RWTH Aachen University is developing a modular powertrain for trucks that allows individual configurations depending on requirements. The integration of a fuel cell system with an electric drive unit serves as the basis. The development focuses on industrializing the production processes for the powertrain. The goal: unit-based cost advantages in manufacturing. "SeLv" stands for "Heavy-duty trucks for zero-emission logistics in heavy-duty transport using electrification modules and an economical production system" and is being funded by the German Federal Ministry of Transport with around 16.9 million euros.
Traffic and transport sector causes 20 percent of CO2 emissions
The background to the research project is the 20 percent share of the traffic and transport sector in Germany-wide greenhouse gas emissions. Heavy goods and commercial vehicles in turn account for around 35 percent of these. To achieve the climate targets, it is therefore necessary to electrify heavy-duty transport in addition to passenger cars for private use. Hydrogen technology has a key role to play here, as underpinned by the German government's National Hydrogen Strategy (NWS).
Converting existing vehicles to electric drive systems
Due to the high energy requirements of heavy trucks, it is important to exploit the technological advantages of the fuel cell – above all the long range and high possible vehicle masses – in order to realize locally emission-free long-distance traffic. This requires not only the renewal of vehicle fleets but also the electrification of numerous existing vehicles.
