Abstract
A battery control IC includes a voltage measurement unit that measures, in a normal current mode, a voltage value of each of a plurality of unit battery cells forming a battery pack, and measures, in a short-time large-current mode, a voltage value of a unit battery cell that has exhibited a lowest voltage value in the normal current mode, and a calculation unit that calculates an available power value of the battery pack in the short-time large-current mode based on a voltage value, measured in the short-time large-current mode, of the unit battery cell that has exhibited the lowest voltage value in the normal current mode.
