Abstract
California’s transition to electric vehicles (EVs) requires more than additional charger counts. Public charging must be accessible, affordable, and reliable where people actually live and travel. This report presents a geospatial dashboard and time-series toolkit for the nine Bay Area counties that maps public charging stations, tracks price and charging-port status at 10-minute intervals, and identifies disadvantaged community (DAC) census tracts using the joint U.S. Department of Energy/U.S. Department of Transportation/National Electric Vehicle Infrastructure (DOE/DOT/NEVI) framework. The tool reports charger availability, utilization, pricing, reliability, and average session cost, and supports equity metrics such as ports per 1,000 residents or renters, travel time to a direct-current fast charger, and tract-level comparisons between DAC and non-DAC areas. It also supports early screening of sites for Level-3 fast chargers by identifying locations that appear feasible from the grid standpoint. The result is a practical planning tool that allows agencies to monitor conditions continuously without field surveys and to target investments toward areas of greatest need.
