The present invention relates to an electric vehicle charging system to charge an electric vehicle using an AC power. Charging the disclosed electric vehicle control system is configured to include an output thereof connected to at least two input terminals and the input end of the charge-side direct-current transformer connected to the respective different minute wiring for supplying the AC power source, from one minute wiring If the power supply is cut off for automatic transfer machine for performing an automatic switching to the other one wire to supply power to the charge-side direct-current transformer; accepted is connected to the output end of the the automatic transfer machine an AC power converted into DC power and; charge side rectifier for feeding to the after electric vehicle charging system; and a DC circuit breaker which is connected to the output terminal of the charge side rectifier; protective barrier controller to and receives applying an external control signal selectively blocks the DC circuit breaker by varying the direct-current power supply input is connected to the at least one power supply line that branches from an output terminal of the DC circuit breaker A second charge switch unit containing the one or more second charge switch to be connected to one or more power selected to be branched from the output terminal of the charge-side direct-current transformer;; and, the second charging switch force of one or more charged side direct-current transformer by storing an identifier corresponding to each of the second one or more charging ports that are connected to the charge switch; when a and the identifier of the charging port on the input of the plurality of second charging switch configured to said second charge switch the by a second switch connected to the charging port corresponding to the identifier on / off charge terminal for controlling the charging of the electric vehicle; composed, including, reducing the installation cost of the electric vehicle charging system, an overload of the commercial power supply a reduced, the power input for charging can be charged using a charging port for various other types of electric vehicles So that by allowing increase the charging efficiency of the electric vehicle.
