ELECTRIC STORAGE DEVICE MANAGEMENT APPARATUS AND METHOD OF EQUALIZING CAPACITIES OF ELECTRIC STORAGE DEVICES

摘要

A method for equalizing states of electric storage devices, which are connected in series, of an electric storage device assembly, includes preparing discharging time period data including discharging time periods associated with sequential numbers, determining whether a voltage of each electric storage device has reached a reference voltage during charging or discharging of the electric storage device assembly, and discharging the electric storage devices, using a discharging circuit, for respective discharging time periods associated with the sequential numbers, the sequential numbers being assigned to the electric storage devices according to a sequence of the electric storage devices determined based on time points at which the voltages of the electric storage devices have reached the reference voltage.
