Investigating the Individual house holders’ preference to adopt home-based charging and solar rooftop facility for electric vehicle charging

ABSTRACT

This study aims to identify the various influencing factors that affect Individual householders’ (IHHs) decision to adopt Home-based charging (HBC) facility supported by the solar rooftop (SRT) system for EV charging. Also, this study aims to prioritize the most suitable policy options to encourage IHHs to adopt HBC and SRT facilities. For this purpose, a questionnaire survey was conducted with IHHs in Ahmedabad city, India, and used 854 data for the analysis. This study finds that the socio-demographic characteristics of IHHs like gender, age, educational qualification, occupation, and vehicle ownership significantly influence EV, HBC, and SRT facilities’ adoption decisions. Adoption of an HBC facility improves IHHs’ confidence for regular EV usage and offers flexibility to charge EV. Further, the most preferred policy is the combined incentives for EV, HBC, and SRT. This study suggests the Policy bundling method to improve EV adoption in India.
