An electric vehicle charging system according to an aspect of the present invention operates a multiple access switch connected to three or more wires of a wire network to connect some of the three or more wires to selectively form a connection path. According to the present invention, since DC power is used as main power supply, power loss is lower than a case when AC power is used, so that efficiency is high, and the current flowing in the wire is low compared to the same power, so that cost can be reduced by using a thin wire.
