The strategic planning of charging facilities is crucial for fostering the adoption of new energy vehicles and ensuring the sustainable development of urban areas. This study comprehensively assessed the spatial distribution and accessibility of public charging facilities across the nine districts within the central metropolitan area of Chongqing, employing the kernel density estimation method and accessibility analysis. The findings reveal distinct accessibility patterns among the nine districts, characterized by higher concentration in central areas, lower coverage in peripheral regions, and non-uniform distribution within local areas. Moreover, significant variations in accessibility levels across different districts were observed. Building upon these findings, the study identifies prevailing issues in the current layout of charging stations and proposes measures to optimize and adjust the charging infrastructure in Chongqing. The aim is to offer practical recommendations for enhancing the overall configuration of charging stations in the city.
