Motivation

One of the key societal challenges of today is the decarbonisation of the road transport. In this context, the ERTRAC Strategic Research Agenda defines guiding objectives demanding by 2030 an 80 % improved energy efficiency of the urban passenger transport and a shift to decarbonisation of the energy needed. The challenging improvement of energy efficiency must be met by introducing advanced power train technologies on the one hand and by significantly reducing the vehicles weight reversing the weight spiral of the last decades on the other hand.

However, the acceptance of hybrid and fully electric vehicle (FEV) is defined by the customer's demand for comfort, individuality and attractiveness (incl. operating range), safety and efficiency. Presently, the attractiveness of those cars is significantly influenced by the purchase cost and most important by the range of the vehicle both dominated by the underlying battery technology. To compensate for the additional weight of the battery and to extend the driving range under electric driving conditions the overall vehicle weight must be reduced drastically. Any significant weight reduction either allows for smaller and lighter battery systems at same range thus reducing the costs or increases the range of the vehicle without increasing the weight and costs of the battery system. As stated by Volkswagen, the electromobility amplifies the challenge in lightweight design for innovative vehicle concepts. The importance of lightweight design increases by reason of the significant influence of the range of electric vehicles. Consequently electric vehicles demand innovative vehicle concepts with significant weight reductions without penalties in comfort (NVH), safety and costs.
