Abstract

PURPOSE:To properly maintain battery using condition in such a way that a counter to make up-down counts of charging and discharging currents in a battery in order to control power supply to a settled machine by this information. CONSTITUTION:Charging current in a battery is detected by the first sensor 1, and discharging current therein is detected by the second sensor 8, which are respectively counted through amplifiers 2, 9, voltage-frequency converters 3, 10, logical circuits 5, 12 by an up-down counter 7. Besides, after the counting information to be adapted to the charging rate in the battery is pre-memorized by a register 13, it is transferred to the counter 7, and UP, DWN conversion by the counter 7 is done with outputs in comparators 4, 11. Comparators 14, 15 are provided for comparing the counting information in the battery which is the output in this counter 7 with discharging depth level and upper limit discharging level which are set by registers 16, 17, and a relay 20 to perform power supply to others than a settled machine is driven by supplying these outputs to a flip-flop circuit 18 and an amplifier 19.
