A remaining capacity calculation unit (110) calculates the remaining capacities of batteries (300-1, 300-2) connected in parallel to one another, and after starting discharge of the batteries (300-1, 300-2), a control unit (130) stops discharge of the first of the batteries (300-1, 300-2) which has a remaining capacity which, calculated by the remaining capacity calculation unit (110), has become the same value as a threshold value stored in a storage unit (120). |
