초록

A battery condition detecting apparatus includes a current detecting apparatus, a voltage detector and a current accumulator of a battery. The battery condition detecting apparatus detects a first battery capacity when an engine is started based on the battery voltage and battery current when the starter is started; determines an initial capacity of the battery based on the first battery capacity; adds to this initial capacity, a battery current accumulated value which has been accumulated by the battery current accumulator after determining the first ba...
