Abstract

In order to limit ongoing global warming, greenhouse gas emissions must be significantly reduced. The electrification of passenger car traffic is making a contribution to this. However, despite public funding for research, acquisition and infrastructure development, development has so far fallen short of political expectations. Currently, around 0.6% of registered passenger cars in Germany are powered purely by battery electricity, which shows that there are adoption barriers on the user side that are hindering market penetration. These include the perception of the state of expansion of the charging infrastructure. Despite progressive expansion, there are unanswered questions regarding positioning and design, as so far it is mainly findings from fossil mobility that are being transferred to the new context, but it is unclear whether the type of drive will result in new user requirements and behaviors that need to be taken into account in planning. This gap is addressed in this work, which uses a consecutive application of qualitative and quantitative empirical methods to investigate, among other things, perception profiles, charging location preferences, and charging behavior patterns and decision criteria in a comparison of current and potential, future e-vehicle users. Both user groups differ only slightly in their perceptions of charging, and refilling events are triggered by the same occasions. While current e-vehicle users tend to need charging infrastructure for long-distance travel, potential users prefer to see charging infrastructure more closely meshed with their local environment. In terms of user diversity, it became clear that socio-demographic factors and personality traits are less relevant in the charging/fueling context than factors related to users' place of residence and mobility. Recommendations for future research and infrastructure planning can be derived from the results.
