PURPOSE:To set the electrode plates to the perfectly discharged condition and suppress over- discharge of electrode plates as much as possible by adjusting a current value to be supplied to the electrode plate through detection of discharged condition of electrode plate from a voltage value between the last electrode pair where electrode plates are opposed in the discharge reservoir and the electrode plate opposing such electrode pair. CONSTITUTION:The fooped alkali storage battery electrode plates 18 are caused to pass continuously through a charging reservoir 1 and discharging reservoir 2 for the forming process. In such a case, a plurality of discharge power supplies 8-11 and a plurality of electrode pairs 25-30 are disposed in the discharge reservoir, a voltage between the electrode pair 30 of electrode pairs 25-30 to which the electrode plate 18 opposes finally and the electrode plate 18 opposing to said electrode pair 30 is detected, a current to be supplied of one or more power supplies among said plurality of power supplies 8-11 is adjusted in accordance with such detected voltage for the discharging. For example, said voltage is adjusted to -1.2V--3.2V by changing a current to be supplied by the power supplies 8-11 to the electrode plate. Thereby, the voltage can be adjusted to such a value as indicating the areas wherein the capacitance exists or does not exist on the electrode plate opposing to the electrode pair 30 and the discharging condition of electrode plate can be supposed. As a result, said voltage is approximated to a value which is indicated when capacitance remains at the entire part of electrode opposing to the electrode pair 30. |
