Minimization of Vehicular Energy Demand

Capacity Area A3 concentrates its research on vehicle technologies for minimization of the energy demand excluding the powertrain itself. This includes new routes to high volume lightweight thermoplastics and bioinspired composites. The functional integration of thermal insulation into composites and thermal management of vehicles as a whole will allow further reducing the non-propulsive energy demand.

The advent of new propulsion and energy storage systems is not the only part that will contribute to the required efficiency increase. In addition a substantial reduction of vehicular energy demand is of great importance. This will be addressed by reducing the vehicle mass with novel recyclable lightweight materials and by addressing thermal insulation and thermal management of the vehicle.

Weight reduction offers advantages like improved handling, braking and reduced propulsion power require-ments. This allows the downsizing of other vehicle components (mass decompounding). Biological compo-sites exhibit outstanding mechanical properties due to their exquisite nano-/microstructure at multiple length scales. Related work will focus on realizing bio-inspired hierarchical composites with thermoplastic (and hence recyclable) matrix for high volume manufacturing. Another related topic is “thermal management in-cluding thermal insulation”. Indeed high-end passenger cars may require as much as 12 kW of auxiliary power under worst case conditions, while the average tractive power requirement (NEDC) would range somewhere between 4-8 kW. Similar relationships hold true for rail transportation which requires up to 50% of its power consumption for thermal management.
