Abstract

PURPOSE:To save the power consumption or a liquid feed pump and allow the black start by controlling the liquid feed quantity or/and operation time of the liquid feed pump in response to the voltage or/and current value of the charge and discharge circuit of a battery. CONSTITUTION:Measurement values of ammeters A1-A3 and voltmeters V1-V2 are fed to a pump current control device 5, the difference between detection values of the ammeters A1, A3 is determined, if the difference is smaller than the preset value, a charge of a battery 1 is started by a solar panel 2. The rotating speed of a liquid feed pump 6 is controlled so that the optimum flow of an electrolyte is obtained in response to the charge current value of the ammeter A2 at this time. If the current values of the ammeters A1, A2 become smaller than the preset values respectively, the operation of the pump 6 is stopped until the measurement value of the voltmeter V2 becomes smaller than the preset value. If the value of the voltmeter V2 becomes smaller than the preset value, the pump 6 is temporarily operated to update the electrolyte.
