Abstract

PURPOSE:To prevent erroneous provision of battery overcharge alarm, by determining the ratio of current levels to be fed from a charging current source and a discharging current source based on a ratio between the ripple component in output voltage and a limit voltage. CONSTITUTION:When the time interval where output voltage V0 of a charging generator exceeds over a limit voltage because of its ripple component is T1, the time interval where the output voltage V0 is lower than the limit voltage is T2 and current level of constant power sources 44, 3 are i0, i1, there is a relation shown by a formula. i2 represents discharge current level when a current mirror circuit 4 operates. When the output voltage V0 drops below the limit voltage, output of a comparator 1 goes to '1' to disable the current mirror circuit 4 so as to charge a capacitor 2 with constant current i1. The constant current i2 is T1/T2 times as high as the constant current i2, and voltage Vd of the capacitor 2 is reset during the time interval T2. Since the voltage Vd of capacitor does not drop to an alarm voltage VB, erroneous alarm is not provided.
