Beschreibung
Zusammenfassung:	An electricity accumulating device includes capacitors (11) connected in series, balanced voltage adjusting portions (13) connected to the capacitors (11) respectively, and a control circuit (15) connected to the balanced voltage adjusting portions (13). The control circuit (15) performs the following operations: measuring two voltages at different times from each other across each capacitor during the non-charge-or-discharge period of the capacitors (11) by using the balanced voltage adjusting portions (13); calculating the absolute value of the difference between the two voltages; determining the balanced voltage of each of the capacitors (11) according to the absolute value; and controlling the balanced voltage adjusting portions (13) to make the voltage across each capacitor (11) a balanced voltage.
