Abstract
A map charging index representing discharge characteristics of a battery is obtained based on a battery voltage under a predetermined discharging operation. The map charging index indicates 100 at a first battery voltage obtainable immediately after the battery starts the discharging operation from a fully charged condition and also indicates 0 at a second battery voltage obtainable when the battery substantially ceases the discharging operation. An accumulative charging index is calculated by subtracting a charged capacity from a temporary full-charge capacity of the battery. The temporary full-charge capacity is corrected based on a difference between the map charging index and the accumulative charging index, thereby obtaining a corrected full-charge capacity. And, a dischargeable capacity of the battery is calculated by subtracting the discharged capacity from the corrected full-charge capacity.
