Users’ perspectives of bi-directional charging in public environments

Vehicle users’ adoption of vehicle-to-grid (V2G) is essential for the system's ability to perform V2G grid services. What charging preferences, needs and routines do EV users have and why? What future expectations do EV users have for bi-directional charging? To answer these research questions, a multimethod study is performed (interviews and survey). The following themes were identified as critical for the acceptance of V2G technology in the everyday life of the interviewees: Convenient and resilient home, minimum range for emergencies, fear of battery degradation, trust in system providers, economic and social incentives, user preferences and need for control. Linear regression models identified associations between sociodemographic characteristics and evaluations of V2G in terms of sustainability and efficiency. The interest in creating resilient homes among certain consumers and EV drivers suggests a demand for services that integrate technologies for home energy efficiency and V2G.
