Abstract
A maximum output power and a discharged electric power amount from the battery is calculated; a future variation in maximum output power relative to the discharged electric power amount is evaluated, thereby determining a remaining capacity of the battery on the basis of the electric power amount discharged until the maximum output power reaches a preset lowest maximum-output power. Thus, the remaining capacity of the battery can be correctly detected, irrespective of the charged state, the discharge rate, the degree of deterioration of the battery and the like.
