    Global primary transportation networks are affected by challenges associated with carbon emissions and rising oil prices. A growing population is opting for electric vehicles (EVs) because of their independent operation without reliance on gasoline and their lower pollution emissions. Establishing a charging infrastructure is necessary to stimulate consumer willingness to pay for EVs. Therefore, this study explored the impact of charging infrastructure on the willingness to pay, as well as the mediating role of driving experience and behavior intentions, using the theory of planned behavior. A quantitative methodology was employed, whereby data were gathered via a survey questionnaire distributed among Thai users residing in Bangkok, Thailand. Statistical analysis was conducted on data collected from 231 potential consumers using structural equation modeling and confirmatory factor analysis to validate the variables. This study revealed that charging infrastructure positively and significantly enhances the driving experience. The driving experience of an EV significantly affects behavior intentions, and positive behavior intentions significantly affect willingness to pay for an EV. Additionally, this study tested the sequential mediation of driving experience and behavior intentions, and the results revealed partial mediation. Furthermore, this study's findings indicate that the government and EV manufacturers should invest in developing charging infrastructure to enhance consumers' willingness to pay.

    Electric vehicles (EVs) have the potential to greatly reduce the amount of gasoline consumed and carbon emissions produced during transportation. Consequently, the Thai government actively advocates for the widespread use of electric vehicles (EVs). This study has examined the factors that influence the adoption of electric vehicles in Thailand, with the moderation of charging infrastructure. The research builds upon the UTAUT2 model and incorporates new elements such as environmental concerns, satisfaction with incentive policies, trust, and the availability of charging infrastructure. Environmental concerns, price value, and hedonic motivation significantly affect use behaviour through trust and behaviour intentions; however, facilitating conditions do not affect them. Habits positively affect use behaviour through behaviour intention, though factors such as effort expectancy and social influence satisfaction with policies showed insignificant results when affecting use behaviour. The moderating effect of charging infrastructure showed an insignificant result.
