Abstract

L'invention concerne la gestion de câbles aériens pour la charge d'un véhicule électrique qui utilise un enrouleur qui accueille un câble muni d'un connecteur pour véhicule électrique. Un ensemble d'entraînement utilise un embrayage à deux positions et un ensemble d'engrenages qui vient séquentiellement en prise avec un pignon d'entraînement pour l'enrouleur afin de dérouler le câble depuis une position aérienne vers une hauteur d'ADA, permettre au câble et au connecteur d'être déployés pour être raccordés au véhicule électrique et enrouler le câble jusqu'à ce qu'une position d'origine verrouillée soit obtenue. La gestion des câbles est intégrée dans une station de recharge pour véhicule électrique qui est montée au plafond, ou une station de recharge pour véhicule électrique montée sur un poteau ou sur un mur. De nombreux modules et caractéristiques sont utilisés en option en association avec le fonctionnement de la gestion de câbles.
