The present invention relates to an integrated charge control system comprising: at least three single phase chargers; at least three phase switching devices for switching a charge phase for charging each of the single phase chargers among a three phase of a three phase AC system; and a central control unit which determines the charge phase for charging according to a request and controls to switch the phase switching devices to the determined charging phase when the vehicle charging is requested from each of the single phase chargers. The occurrence of three phase imbalance can be effectively suppressed by implementing the integrated charge control system of the present invention.
