Queries OpenStreetMap for charging stations within a radius of a point and returns each with its position, distance, operator, network, connector types with their individual power ratings and socket counts, access restrictions, fee status, opening hours and whether authentication is required. Results are sorted nearest first and can be filtered to a minimum power or a required connector type, which is the question a vehicle actually has.
