Optimizing Electric Vehicle Charging Infrastructure in Rhodes Island: Current Status and Voronoi-Based Expansion Analysis

The spatial allocation of infrastructure is a key aspect of operational research and computational geometry, particularly in identifying optimal locations for electric vehicle (EV) charging stations. This paper examines the distribution of electric chargers’ stations across the Municipal Units of Rhodes island, detailing the number and location of existing charging points. The same examination is also referenced for the island of Chalki, which is the primary focus of the NHSOS project, which aims to develop the know-how, infrastructure, methodology and policies to make the Greek islands "Green". In order to evaluate the adequacy of the current infrastructure, we employ the Voronoi diagram methodology in conjunction with population data. This approach enables us to identify potential gaps in coverage and determine the optimal location for additional charging stations, based on spatial and demographical factors.
