Empirical Analysis of Technology Acceptance of Private Electric Vehicle Charging Infrastructure in Germany

Private charging infrastructure is critical to the diffusion of electric vehicles. However, as with all technologies, user acceptance is of primary importance here. This paper analyzes this acceptance with an empirical study with 488 participants. For this, a context-specific technology acceptance model including 9 hypotheses is developed. To validate the hypotheses, an online survey is designed for the German market. Results deliver insights on the general opinion on electromobility and private charging infrastructure and determine the factors influencing the acceptance behavior of potential users with regard to private charging infrastructure. Regarding the general opinion, most of the survey participants show a positive attitude. Regarding the factors, some, such as perceived effort and perceived usefulness, have an influence on the acceptance, while other factors, such as visual design and perceived cost, don't.
