Abstract
Over the past decade, as consumers have gradually adapted to electric vehicles, the production and sales of electric vehicles have grown in tandem, and the deployment of charging facilities has increased dramatically. However, along with the rapid development in scale, charging facilities face problems such as low utilisation during off-peak hours and excessive congestion during peak hours. Therefore, research on the spatial and temporal distribution of charging station loads is of great value. In this context, this study focuses on the spatio-temporal distribution characteristics of charging station loads, especially when analysing the spatial distribution characteristics. This study defines the spatially dependent characteristics of short and long distance. In order to be closer to real charging scenarios, this study considers the influence of road network information and point-of-interest data on the spatial distribution of loads. The spatial and temporal variations of loads and influencing factors are considered more comprehensively and richly, and the spatial characteristics are delineated in detail.
