In order to actualize a power feeding control apparatus and a charging system that are capable of efficiently charging plural storage batteries using a load-capacity controlled power source, the power feeding control apparatusis configured so that a changeover control of the feeding of the alternating-current voltage to each charger will be performed monitoring the magnitude of the alternating current flowing in each of the plural chargersto, therewith, the power feeding control apparatus performs the feeding changeover control comprising the steps of: feeding only to a predetermined one particular charger at the early stage of the start of charging, in which stage a large charging current flows into a storage battery; monitoring inflow current of the predetermined one particular charger; and switching power feeding to another charger to start feeding thereto when the inflow current reduces to the charging saturation current (a current still flowing even at the fully charged state).
