La station de charge (1) peut fonctionner dans une pluralité de modes comprenant un mode de charge destiné à charger et/ou décharger un véhicule électrique (3), un mode d'appariement pour l'appariement avec le véhicule électrique (3) précédant le mode de charge et un mode de veille précédant le mode d'appariement. Le procédé comprend les étapes suivantes : la réception (S41) d'informations d'autorisation prédéterminées au moyen de l'unité de réception (120), puis la commutation (S42) de la station de charge (1) au mode de veille, la station de charge (1) étant commutée vers le mode de veille exclusivement lorsque les informations d'autorisation prédéterminées sont reçues, et par la suite la commutation (S43) de la station de charge (1) du mode de veille au mode d'appariement pour l'appariement avec le véhicule électrique (3).
