Summary: | The present invention relates to an electric vehicle charging system including a plurality of network-connected chargers, wherein a charger may comprise: a power module that stores DC power; an output port that supplies power outputted from the power module to an electric vehicle; a sharing port connected to a sharing port of at least one neighboring charger to receive power shared by the neighboring charger or transmit power of the power module to the neighboring charger; first and second switches that are respectively installed between the power module and the output port and between the power module and the sharing port; and a control unit that controls the operation of the power module and the respective switches according to a request for charging the electric vehicle and, if the maximum charging power of the electric vehicle is greater than a rated output power of the charger, transmits the power shared by the neighboring charger in a currently idle state and the power outputted from the power module together to the electrical vehicle in a paired state with the neighboring charger to charge the electric vehicle at high speed.
La présente invention concerne un système de charge de véhicule électrique comprenant une pluralité de chargeurs connectés au réseau, un chargeur pouvant comprendre : un module d'alimentation qui stocke du courant continu ; un port de sortie qui fournit de l'énergie délivrée à partir du module d'alimentation à un véhicule électrique ; un port de partage connecté à un port de partage d'au moins un chargeur voisin pour recevoir de l'énergie partagée par le chargeur voisin ou transmettre de l'énergie du module d'alimentation au chargeur voisin ; des premier et second commutateurs qui sont respectivement installés entre le module d'alimentation et le port de sortie et entre le module d'alimentation et le port de partage ; et une unité de commande qui commande le fonctionnement du module d'alimentation et des commutateurs respectifs selon une demande de charge du véhicule électrique et, si l'énergie de charge maximale du véhicule électrique est supérieure à une énergie de sortie nominale du chargeur, transmet l'énergie partagée par le chargeur voisin dans un état actuellement inactif et l'énergie délivrée à partir du module d'alimentation ensemble au véhicule électrique dans un état apparié avec le chargeur voisin pour charger le véhicule électrique à une vitesse élevée.
네트워크 연결된 복수의 충전기를 포함한 전기차 충전시스템에 있어서, 충전기는, 직류 전력을 저장한 전력모듈과, 전력모듈에서 출력되는 전력을 전기차로 공급하는 출력포트와, 적어도 하나의 이웃 충전기의 공유포트과 서로 연결되어, 이웃 충전기에서 공유한 전력을 입력받거나 전력모듈의 전력을 이웃 충전기로 전달하는 공유포트와, 전력모듈과 출력포트 사이 및 전력모듈과 공유포트 사이에 각각 설치된 제1 및 제2 스위치, 및 전기차 충전 요청에 따라 전력모듈과 각 스위치의 동작을 제어하되, 전기차의 최대 충전전력이 충전기의 정격 출력전력보다 크면, 현재 유휴 상태의 이웃 충전기와 페어링된 상태에서 이웃 충전기가 공유한 전력과 전력모듈이 출력한 전력을 출력포트로 함께 전달하여 전기차를 고속 충전시키는 제어부를 포함할 수 있다. |
