Abstract

La présente invention concerne un chargeur sans fil mobile pour un véhicule électrique, qui : en communiquant sans fil avec un terminal de communication en champ proche (NFC), reçoit des informations de charge de véhicule électrique qui ont été obtenues par le terminal NFC au moyen d'une carte NFC d'un utilisateur de véhicule électrique qui est étiquetée avec le terminal NFC, puis le terminal NFC reçoit, par l'intermédiaire d'un écran d'interface utilisateur (IU) affiché sur le terminal NFC, le type, l'emplacement de stationnement et la direction de stationnement (par exemple, stationnement en avant ou en arrière) du véhicule électrique ; puis entre dans l'espace inférieur du véhicule électrique, recherche un emplacement de charge sur la base du type de véhicule et de la direction de stationnement, puis actionne verticalement un plateau de charge et charge le véhicule électrique sans contact dans un état dans lequel le plateau de charge est amené à proximité d'un plateau de charge du véhicule électrique. La présente invention recherche un emplacement de charge sur la base d'un type de véhicule et d'une direction de stationnement, et peut ainsi rechercher rapidement un emplacement de charge selon chaque type de véhicule, et en particulier, étant donné que le plateau de charge est actionné verticalement, la présente invention permet de charger un véhicule électrique, quel que soit le type du véhicule électrique, en entrant dans l'espace inférieur du véhicule électrique.
