Mapping the Accessibility of EV Charging Stations in the US

This study examines the spatial distribution and socio-demographic factors influencing the accessibility of EV charging stations in the US. Using data from the National Renewable Energy Laboratory, the analysis reveals a significant positive correlation between median household income and the availability of Level 2 EV charging stations. However, no significant relationship was observed for Level 3 charging stations. These findings highlight income-based disparities in EV infrastructure distribution, raising concerns about transportation equity. The results underscore the need for targeted policy interventions to address inequities in charging infrastructure deployment, particularly in underserved communities. While the study provides a robust quantitative analysis, further research is needed to explore the temporal dynamics of EV accessibility and its implications for sustainable transportation. This study contributes to the growing body of literature advocating for equitable access to green transportation technologies as part of a comprehensive approach to addressing climate change and social inequality.
