Abstract

L'invention concerne une station de charge (2) pour un véhicule automobile (1) qui présente un accumulateur d'énergie électrique (15), comportant : - un emplacement (4) pour le véhicule automobile (1), et - une unité de charge (5) permettant de recharger l'accumulateur d'énergie électrique (15) lorsque le véhicule automobile (1) est arrêté à l'emplacement (4). L'invention vise à empêcher un blocage de la station de charge (2) par des véhicules automobiles non autorisés. À cet effet, la station de charge (2) présente : - une unité d'identification (6) servant à identifier le véhicule automobile (1) avant l'arrêt du véhicule automobile (1) à l'emplacement (4) et - un dispositif de blocage d'accès (3) servant à bloquer l'accès à l'emplacement (4) ainsi qu'à permettre l'accès à l'emplacement (4) en fonction d'un résultat lors de l'identification du véhicule automobile (1).
