An electric vehicle charging system according to one aspect of the present invention operates a multiple connection switch connected to three or more electric wires of an electrical grid, so as to connect some electric wires from among the three or more electric wires, and thus can selectively form connection paths. The multiple connection switch comprises: multiple directional contacts that enable, through longitudinal conductors, the incoming and outgoing of electricity and are connected from the outside; internal wirings formed as longitudinal conductors that mutually connect the contacts; one or more switches provided in the corresponding internal wirings to perform the role of connecting or disconnecting any one part of the internal wirings; and a control unit capable of turning the switches on or off.

    Un système de charge de véhicule électrique selon un aspect de la présente invention fait fonctionner un commutateur de connexion multiple connecté à trois fils électriques ou plus d'un réseau électrique, de manière à connecter certains fils électriques parmi les trois fils électriques ou plus, et peut ainsi former sélectivement des trajets de connexion. Le commutateur de connexion multiple comprend : de multiples contacts directionnels qui permettent, par l'intermédiaire de conducteurs longitudinaux, l'entrée et la sortie d'électricité et sont connectés depuis l'extérieur ; des câblages internes formés en tant que conducteurs longitudinaux qui relient mutuellement les contacts ; un ou plusieurs commutateurs disposés dans les câblages internes correspondants pour effectuer le rôle de connexion ou de déconnexion d'une partie quelconque des câblages internes ; et une unité de commande permettant d'activer ou de désactiver les commutateurs.

    본 발명의 일 측면에 따른 전기자동차 충전 시스템은, 전선망의 3개 이상의 전선과 연결되는 다중접속스위치를 동작시켜, 상기 3개 이상의 전선 중 일부 전선들을 연결하여 선택적으로 연결경로를 형성할 수 있다. 다중접속스위치는 길이방향의 도체로 외부에서 연결된 전기 인입과 인출이 가능한 복수개 방향의 접점, 접점들을 상호 연결하는 길이 방향의 도체로 형성된 내부배선들, 내부배선 중 어느 한 부분을 연결하거나 끊는 역할을 할 수 있는 해당 내부배선에 설치되는 하나 이상의 스위치, 및 스위치를 온 또는 오프할 수 있는 제어부를 포함하는 것을 특징으로 한다.
