With the rise in the popularity of electric vehicles (EVs), the challenge of creating reliable and easily accessible charging stations has gained significance in developing sustainable transportation. Few studies have been conducted to look at the EV users' satisfaction with the charging stations and the relationship between users' satisfaction and their intention to use EVs, particularly in cities that are not mature such as Bhubaneswar. The current study has been designed to explore the factors influencing the satisfaction level of charging infrastructure and to understand their influence on EV users' continued EV usage intent in Bhubaneswar. A quantitative, descriptive and explanatory study was used. The primary data was collected from EV users from 350 samples by using a structured questionnaire with 5-point Likert scale. The three independent variables were: Charging Infrastructure Accessibility, Charging Speed & Reliability, Charging Cost and the mediating variables were Charging Infrastructure Satisfaction, and the dependent variable was Continued Usage Intention. The collected data were analyzed descriptively, reliability analysis, exploratory factor analysis (EFA), Pearson correlation analysis and multiple regression analysis were used to analyze the data in IBM SPSS Statistics. The results show that all the four charging infrastructure attributes are positively and significantly related with charging infrastructure satisfaction. Of these, Charging Speed & Reliability was the most significant, followed by Digital Payment Convenience, Charging Infrastructure Accessibility, and Charging Cost. The study also revealed that Charging Infrastructure Satisfaction is a significant positive factor influencing Continued Usage Intention, meaning that satisfaction with the charging infrastructure triggers the likelihood of continued use of EVs and their promotion to others. Reliability analysis revealed highly internal consistent measurement instrument and exploratory factor analysis revealed satisfactory construct validity. It is concluded that the improvement of the accessibility, reliability, charging efficiency, cost, and digital payment facilities for charging stations are key to increase user satisfaction and foster the long-term EV adoption. The study provides some policy recommendations for the policymakers, charging infrastructure companies, EV manufacturers, and urban planners to build the electric mobility ecosystem in Bhubaneswar and India's transformation to sustainable mobility.
