Abstract:
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 power feeding control apparatus to charge plural storage batteries connected in parallel, wherein said power feeding control apparatus performs power feeding changeover control processings comprising the steps of feeding only to a first charger at an early stage of the start of charging, in which stage a large charging current flows into a first storage battery; starting the power feeding to a second charger when an inflow current of said first charger reduces to a charging saturation current by monitoring said inflow current of said first charger; and starting the power feeding to a third charger when an inflow current of said second charger reduces to a charging saturation current by monitoring said inflow current of said second charger, and wherein said first charger is configured so that the maximum value of the inflow current of the received alternating-current voltage will be not greater than a first maximum value; said second charger is configured so that the maximum value of the inflow current of the received alternating-current voltage will be a second maximum value that is the remainder of subtraction of charging saturation current of said first charger from said first maximum value; said third charger is configured so that the maximum value of the inflow current of the received alternating-current voltage will be a third maximum value that is the remainder of subtraction of said charging saturation current of said first charger and charging saturation current of said second charger from said first maximum value.
