    摘要： A state-of-charge equalizing device equalizes the state of charge of each of cells connected in series to form an assembled battery, and comprises charging/discharging circuits connected in parallel to the respective cells to discharge and/or charge the respective cells, voltage measurement circuits connected to the respective charging/discharging circuits to measure the voltages across the respective cells, and a control circuit. The control circuit comprises a unit calculating an equalization target voltage based on the measured voltages before the charge or discharge starts, a unit starting discharging/charging the cells having a voltage thereacross different from the target voltage, a unit correcting the target voltage to thereby calculate a corrected equalization target voltage for each of those cells based on the difference between the measured voltages before and at a certain time period after the charging/discharging, and a unit ending the discharging/charging when the measured voltage reaches the corrected target voltage.

    摘要： A battery ECU acquires open circuit voltages of a plurality of battery cells that are divided into a plurality of groups A, B, C using a plurality of detecting units, and calculates SOCs of the battery cells based on the open circuit voltages. Then, the battery ECU selects the group to which the battery cell having the largest SOC among the SOCs of the plurality of battery cells belongs, and selects the battery cell to be discharged in the selected group. A series circuit composed of a resistor and a switching element is connected in parallel with each battery cell. The battery ECU turns on the switching element corresponding to the selected battery cell. At this time, the battery cell is connected to the resistor, thus being discharged.
