Abstract
In a device for controlling an assembled battery provided with a plurality of single batteries, the device includes a capacity adjustment section for adjusting a capacity such that voltages of the single batteries are equalized at a targeted voltage, an internal state detection section for detecting terminal voltages or SOC of the single batteries and for detecting, based on the detected terminal voltages/SOC, a voltage/SOC difference among the single batteries as voltage-difference/SOC-difference data, and a time-series data storage for storing the voltage-difference/SOC-difference data in time-series. Also provided is a prediction section for more appropriately predicting time when the assembled battery becomes an abnormal state, based on a time-dependent change in the voltage-difference/SOC-difference data detected in a voltage/SOC region different from the targeted voltage by a predetermined voltage, among the stored time-series voltage-difference/SOC-difference data.
