摘要： A voltage equalization device (200) of a power storage device (300) provided with battery packs (20) in which a plurality of secondary cells are connected, power converters (30) provided in association with the battery packs (20), and controllers (40) that control the power converters (30), and in which the battery packs (20) are connected in parallel via the individual power converters (30) includes a decision portion and a voltage-adjusting portion. The decision portion obtains battery-pack information regarding the states of charge/discharge of the individual battery packs 20 and decides, for each battery pack (20), whether or not to perform voltage adjustment on the basis of the battery-pack information. When the decision portion decides that the voltage adjustment is to be performed, the voltage-adjusting portion generates offset instructions for adjusting the states of charge/discharge and outputs the offset instructions to the controllers (40) of the power converters (30) associated with the battery packs (20).

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.
