An electric vehicle charging system according to one aspect of the present invention operates a multi-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 multi-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.
