Going on a road-trip with my electric car: Acceptance criteria for long-distance-use of electric vehicles

Abstract

In this study we report on four focus group discussions to examine cognitions, attitudes of a broad variety of users with respect to battery electric vehicles (BEV). Specifically, we identified relevant criteria for the use of electric cars as a long distance vehicle and gathered first impressions of where users wish to locate such charging stations. Four main aspects were identified as acceptance relevant: The battery’s capacity, given in the driving range in kilometers, the time it takes to regain this given range (charging time), the density of the charging stations grid and the attractiveness of the places where the charging stations are located, which could for example be a service area or a simple parking lot off the highway. Results of this study might provide detailed insights into conditions and technical specifications that have to be met beyond the possibility of quick charging to reach higher acceptance and a broad willingness to use BEVs for more than short-tracks in the city.
