Abstract
A micro discharge detection current which is obtained by reducing a discharge current of a battery at a predetermined ratio is detected by a current amplifying circuit and an integration voltage showing a discharge charge amount is formed by charging a capacitor of an integrating circuit. The integration voltage of the integrating circuit is compared with a reference voltage showing a predetermined unit charge amount by a comparing circuit. When the integration voltage reaches the reference voltage, a comparison output is inverted and the capacitor of the integrating circuit is discharge reset and one pulse signal showing the unit charge amount is generated by the inversion of the comparison output. The pulse signal from the comparing circuit is counted by a counter and the count value is multiplied with the unit charge amount, thereby obtaining the present discharge charge amount of the battery.
