<P>PROBLEM TO BE SOLVED: To provide a discharge control system capable of supplying electric power to a load, even when the cell voltages of an electric storage pack are uniform. <P>SOLUTION: A discharge controller of an electric storage pack controls a discharge line connected to a rotary inductive load or a load driving feeding circuit from a plurality of electric rechargeable cells connected in series within the pack. The discharge controller includes a cell voltage detection unit which detects respective cell voltages of the plurality of electric rechargeable cells; a switch group constituted of a plurality of switches connected between the plurality of electric rechargeable cells; and a control unit which controls individually the switches of the switch group, according to the results of detection by the cell voltage detecting unit, when a difference between a highest cell voltage and a lowest cell voltage in the electric rechargeable cells of the electric storage pack is equal to or smaller than a predetermined value and forms a discharge line, from at least one of the plurality of electric rechargeable cells to the rotary inductive load or the load driving feeding circuit. <P>COPYRIGHT: (C)2009,JPO&INPIT |
