PURPOSE: An integral recharging control system is provided to efficiently suppress three-phase inequilibrium which is caused by multiple battery chargers which charge electricity through a three-phase power source to an electric vehicle. CONSTITUTION: An integral recharging control system includes at least three single-phase battery chargers(41-49); at least three phase converting devices(31-39) which convert charge phases in order to charge each single charger among three phases of a three phase AC system; and a central control unit(10) which determines a charging phase for charging according to a request when the recharge for the vehicle is requested by a single-phase charger.
