Lightweight Feeling - Driving Excitement, Vehicle Efficiency and Costs of BEV in Conflict

Schrank, Georg / Arntz, Martin / Sams, Christoph

Increasingly stringent exhaust emission regulations and CO₂ fleet emission targets are leading to a continuous electrification of vehicles. The market share of battery electric vehicles (BEVs) is increasing significantly due to the growing supply, sales promotion programs and environmental bonuses, as well as increasing awareness of environmental issues among end consumers. The key criteria for end consumers when it comes to the procurement of a BEV are range, charging time, charging infrastructure and vehicle costs; here, vehicles with conventional drives have an advantage.

Although electric powertrain configurations and their higher “tank to wheel” efficiencies allow efficiency improvements, increases in electric ranges mostly require larger and thus heavier batteries. Although this usually leads to low centers of gravity, additional functional measures are needed to make the higher vehicle weight less noticeable.

The focus of this paper is on introducing a methodology to assess and develop driving dynamics for a low perceived vehicle weight of BEVs. The so-called lightweight feeling. In addition, measures for improvement, their impact as well as their related costs are introduced. Beside the characterization and identification of measures for improvement with AVLs attribute engineering approach, a methodology, which allows to resolve and optimize that the tension between costs, efficiency and driving experience very early in the virtual concept development, will be addressed.
