Positive influence of practical electric vehicle driving experience and range related knowledge on drivers' experienced range stress

The challenge of reducing worldwide greenhouse gas emissions has become increasingly important in recent years. Battery electric vehicles (BEVs) are a promising alternative having the potential for a CO₂ neutral and sustainable utilization over the whole vehicle lifetime. However, BEVs limited range is still considered as one important usage barrier. Reducing drivers' experience of range stress is discussed as one possibility to overcome this barrier. The objective of the present research was to investigate the influence of range related knowledge, practical driving experience and the encounter of a critical range situation (i.e., experience of a small range buffer) on drivers' range stress. A specific focus lied on the effects of critical range situation encounters on experienced BEV drivers. A field experiment with 63 participants (20 experienced drivers and 43 inexperienced drivers) who drove a BEV in a critical range situation was conducted. Results indicate that range related knowledge and practical driving experience reduced range stress. The experience of the critical range situation is related to lower range stress, even for the experienced BEV drivers. The results can be useful to derive strategies and design recommendations aimed at reducing the experience of BEV drivers' range stress.
