Abstract

La présente invention concerne un système de charge de véhicule qui, lorsqu'un détachement de câble s'est produit au cours d'une charge dans une installation dans laquelle plusieurs stations de charge sont disposées au même endroit, permet que les stations de charge identifient le véhicule où s'est produit le détachement de câble, et un état du véhicule au moment de l'occurrence du détachement de câble. Une communication sans fil est établie avant la charge grâce à l'utilisation d'un identifiant de véhicule. Ensuite, lors de l'occurrence du détachement de câble pendant la charge, un signal de détection de détachement de câble, des informations de surveillance et l'identifiant du véhicule sont transmis par la communication sans fil depuis un appareil de commande de charge (11) vers une station de charge (12). Le signal de détection de détachement de câble indique qu'un câble s'est détaché pendant la charge. Les informations de surveillance indiquent un état d'un véhicule.
