    摘要： The battery state-of-charge calculation device (100) is provided with a SOCV calculation unit (5) which outputs a first state of charge calculated based on voltage data, a SOCI calculation unit (6) which outputs a second state of charge calculated based on current data, an estimated impedance voltage calculation unit (12) which calculates an impedance voltage value based on an effective state of charge and the current data, a static determination unit (7) which determines that the impedance voltage value remains static for a predetermined time or longer in a range identified by a predetermined threshold value and outputs the determination result; and a SOC decision unit (20) which, based on the determination result, outputs the first state of charge as the effective state of charge where the impedance voltage value is static and outputs the second state of charge as the effective state of charge where the impedance voltage value is not static.

    摘要： An object is to reliably conduct cell balancing operation while suppressing deterioration of batteries and maintaining operating efficiency. When the cell balance control by the cell balancing circuit 3 is started, the system control device 30 sets an on/off device corresponding to the arm where the cell balance control is conducted to the open state; and when the cell balance control is completed, and the difference between the terminal voltage of a battery pack of the arm where the cell balance control has been conducted and the terminal voltages of the battery packs of the other arms falls within a preset allowable range, sets the on/off device, which has been in the open state, to the closed state.
