Abstract

L'invention concerne une station de charge destinée à des véhicules électriques. Ladite station de charge est équipée d'un système de localisation configuré pour recevoir des informations de position, d'un système de mémoire configuré pour mémoriser des informations de position et d'un système de comparaison configuré pour comparer les informations de position reçues avec les informations de position mémorisées. L'invention vise à assurer qu'une station de charge réalise des valeurs de mesure avec des informations de position vérifiables. A cet effet, en cas de résultat de comparaison négatif, les informations de position mémorisées sont remplacées par les informations de position reçues et un enregistrement concernant les informations de position modifiées est créé en outre dans un journal de bord.
