An electric storage device management apparatus(20) is provided for monitoring an electric storage device assembly(12) charged and discharged by a charger/discharger(18). The electric storage assembly(12) includes a plurality of electric storage devices(50) connected in series. The electric storage device management apparatus(20) includes a voltmeter(24), a discharging circuit(26), and a controller(30). The voltmeter(24) is configured to measure voltages of the electric storage devices(50) respectively. The discharging circuit(26) is configured to discharge the electric storage devices(50) individually. The controller(30) is configured to: determine whether a voltage of each electric storage device(50) has reached a reference voltage during charging or discharging of the electric storage device assembly(12); and control the discharging circuit to discharge each electric storage device(50) if the voltage of the electric storage device(50) has reached the reference voltage.
