Abstract Unlike refueling at gas stations, charging an electric vehicle (EV) requires significantly more time, ranging from 20 minutes to over an hour, even with the fastest chargers. This prolonged charging duration introduces unique complexities to the fundamental understanding of public charging station (PCS) accessibility, raises questions about the ongoing relevance of spatial proximity for different population groups, and highlights the need to consider amenities near PCS that users can access along their daily routines. To account for these critical distinctions, we introduce visit-based accessibility, a metric that evaluates PCS availability relative to amenities frequented during urban routine activities. Leveraging data from over 28,000 PCSs, 5.2 million points of interest (POIs), and mobility patterns from more than 35 million cell phone users across 20 major U.S. metropolitan areas, we reveal a striking mismatch between PCS locations and the spatial proximity to and the daily needs of their intended users. While existing PCSs are spatially proximate to lower-income communities, our visit-based measure reveals significant disparities, as these communities' routine activities align significantly less with PCS locations. Furthermore, when considering dwell time at nearby amenities, higher-income communities exhibit better alignment of PCSs with routine activities and longer dwell times at nearby POIs, which are also the most extensively covered by existing PCSs. Finally, our analysis reveals that experienced income and racial segregation are likely the major impedance for accessing PCSs that are spatially adjacent, which highlights a hidden social barrier where greater divergence from typical social encounters near charging infrastructure is associated with lower visit rates to PCSs. These findings underscore the necessity for targeted strategies to ensure equitable access to charging infrastructure, addressing both spatial and functional disparities to promote sustainable and inclusive urban development.more » « lessFree, publicly-accessible full text available January 24, 2026
