Power Feeding Control Apparatus and Charging System
First Claim
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.

Abstract
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 apparatus 1 is 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 chargers 4 to 6, 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).
