1. A charging system comprising a power feeding control apparatus that distributes the alternating-current voltage received from a single alternating-current power source to plural chargers, and a plurality of chargers that rectify and smooth said alternating-current voltage received from said alternating-current power source to charge plural storage batteries parallel, wherein said power feeding control apparatus is configured so that a changeover control of the feeding of said alternating-current voltage to each of said plural chargers will be performed monitoring the magnitude of the alternating current flowing in each of said plural chargers, therewith, said 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 said predetermined one particular charger; and

    switching power feeding to another charger to start feeding thereto when said inflow current reduces to the charging saturation current.
