Public’s Perception of Adopting Electric Vehicles: A Case Study of Singapore

This study aims to investigate public's perception towards electric vehicles (EVs) in the context of Singapore by means of survey. Specifically, some unique characteristics such as public's awareness of national incentives, e.g., carbon emission-based vehicle scheme (CEVS), are identified as potential influential factors. The stepwise regression analysis is employed to select a best set of factors for the estimation of respondents' purchasing intention of EVs by a multiple linear regression model. Unlike other countries, we find that the two most influential attributes are the high cost of Certificate of Entitlement (COE) and purchase price of EV, whereas only a minority of respondents list the driving range as their major concern. The resale value of EV is an important consideration for majority of respondents. Moreover, compared with normal charging at public stations, Singaporeans are likely to preform fast charging and home charging. Finally, several recommendations are provided to facilitate EVs' deployment.
