Reduction of lifecycle costs in electrical distribution traffic through individually adaptable drive train

Project Logo

Motivation and procedure

Traffic and transport are the second-largest sources of harmful CO2 emissions and make a major contribution to total NOx emissions. Freight transport and, in particular, the constantly growing distribution traffic make up a significant proportion of this. At the present time, however, there is no electro-mobile and economical solution for the use of trucks of the EC vehicle class N3 up to a maximum permissible gross weight of 26 tons. It is therefore necessary to build up a solution area that enables the users to use these vehicles in an optimized way regarding the life cycle costs.

Research objectives

The superior aim is to modularize the drivetrain for optimal handling of different customer needs, considering a cost-oriented design and integration. The research of modular structures derived from customer requirements, the integration of the modules into a complete vehicle, and the validation of the drivetrain topologies derived from the drivetrain construction kit by building pilot vehicles are the core components of the research project. Furthermore, a new industrialization approach for the cost-efficient production of such a modular drivetrain kit is being researched. Further goals are:

  • Modular component solutions for drivetrain, energy storage and e/E-Systems
  • Adaptability of the kit to different installation spaces
  • Flexible production and integration of battery pack and drive unit
  • Flexibility of component production using additive manufactured tools
