Abstract
A battery pack () includes a plurality of battery cells (), a measurement unit (measurement unit ()), and a battery control unit (battery control unit ()). The plurality of battery cellsare connected in series to each other. The measurement unit () measures voltages of the battery cells (). The battery control unit () controls discharge of the battery cells () on the basis of the voltages measured by the measurement unit (). In addition, when the battery cells () perform the discharge, the battery control unit () specifies a minimum voltage cell in which the voltage is lowest on the basis of the voltages measured by the measurement unit (). Further, before the minimum voltage cell is over-discharged, the battery control unit () outputs a first signal for reducing a discharge current in the discharge.
