Abstract
A battery control apparatus includes a reduced electricity cost analysis unit that obtains a discharge electric power cost at a discharge time and a charge electric power cost at a charge time of a battery, based on a basic cost and a unit cost of an electricity bill, and obtains a reduced electricity cost in which the charge electric power cost is subtracted from the discharge electric power cost for every discharge depth of the battery; an introduction cost analysis unit that calculates an introduction cost of the battery for every discharge depth of the battery; and a charge and discharge depth optimization unit that obtains a difference of the reduced electricity cost and the introduction cost for every discharge depth of the battery, and determines a charge and discharge depth of the battery based on the difference. The discharge of the battery is performed at the determined charge and discharge depth.
