Abstract:

The objective of this study is to identify factors that influence actual electric vehicle (EV) drivers’ acceptance of Vehicle-to-Grid (V2G) charging. The study takes a qualitative approach in order to provide insight into actual EV users’ perceptions of V2G technology and their underlying motivation to accept or not accept V2G. To build a basic conceptual model of the various factors impacting users' acceptance of V2G, the Theory of Planned Behaviour is used. Twenty semi-structured interviews with Dutch EV drivers are undertaken, comprising both regular EV drivers and those who have previously participated in V2G projects.  The factors that are found to be most important for fostering acceptance are financial compensation, transparent communication and reliable control of the system by the user. On the other hand, the factors that are found to have a negative effect on acceptance are range anxiety, discomfort experienced while participating and battery degradation. The majority of interview participants accept V2G, albeit with some reservations and caution, according to this study. Due to the fact that EVs and V2G are relatively new technology, the sample of twenty genuine EV users includes early adopters. As a result, their viewpoints may differ from those of the vast majority of future users. However, this study implies that some EV users are willing to use V2G charging stations and will do so in the future. The study goes on to explain the reasons behind such user acceptability, as well as provide more insights and research ideas for the future.
