ABSTRACT:
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 battery capacity, whereby a second battery capacity is detected after the engine has been started; and further comparing the presently detected first battery capacity with the second battery capacity just before this first battery capacity is detected, thereby setting the smaller capacity as the initial value. Then, a charge control apparatus for a vehicle sets a battery charging target value, depending on the initial capacity which has been set by the initial capacity setting apparatus of this battery condition detecting apparatus, and controls the alternator in such a manner that the battery is charged at this target value.
