About Paper:

Electric vehicles (EVs), compared to conventional vehicles, have significantly lower emission levels and are a promising alternative to address sustainability concerns. Amidst growing technological innovations, EV registrations have risen substantially in the U.S. This raises sufficient investment and developmental strategizing concerns for essential advances in EV and charging infrastructure to suit future requirements. We use EV registration data with economic and socio-demographic variables - as factors that influence EV adoption - for 17 states from 2010-2021. This study aims to: (a) visualize EV registration trends across states by EV makes, models, powertrain types and gross vehicle weight categories, (b) identify economic and socio- demographic factors affecting EV penetration rate across U.S. counties to understand future EV penetration (total EVs/total vehicle population), and (c) understand the influence of cross-county proximity on other counties' EV penetration through spatial time-series analysis. California, New York, and Washington have shown the highest number of EV registrations over the years, with light-duty EVs having the highest share in EVs and an increased adoption in heavy-duty EVs post-2018. We find charging stations availability, average household income and commute time to have a significant impact on EV penetration rates. Furthermore, we find strong correlation in increased EV penetration between neighboring counties, and counties with higher EV penetration to have a stronger influence than others. We contribute by identifying definitive factors that influence EV adoption and forecast penetration to suggest policy implications to manufacturers for adequate future investment planning in EV infrastructure expansion.
