    摘要： It is an object to effectively output electrical energy of a storage battery to an electrical power system serving as a whole distributed power supply system by effectively utilizing the electrical energy within a charging ratio range that does not cause overcharging or overdischarging of the storage battery. In a hybrid distributed power supply system, the target supply electrical power is set based on the electrical power generation output of the electrical power generator and the charging state of the storage battery, and the target supply electrical power is restricted within a predetermined permissible supply electrical power range when the target supply electrical power deviates from the predetermined permissible supply electrical power range.

    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.

    摘要： The disclosed charging-rate computation system outputs a first estimated charging rate on the basis of the estimated open-circuit voltage of a secondary cell, outputs a second estimated charging rate on the basis of the cell capacity of the secondary cell and the results of integrating the measured current of the secondary cell as well as the upper error bound thereof over a predetermined cycle, outputs a third estimated charging rate on the basis of the cell capacity and the results of integrating the measured current as well as the lower error bound thereof over the predetermined cycle, and outputs a fourth estimated charging rate on the basis of the cell capacity and the results of integrating the measured current over the predetermined cycle. In the time period within the predetermined cycle, the abovementioned fourth estimated charging rate is output as the charging rate, and at the endpoint of the predetermined cycle: when the first estimated charging rate is a value of an estimated charging rate between the second estimated charging rate and the third estimated charging rate, the first estimated charging rate is considered the charging rate; when the first estimated charging rate is a value that is at least the second estimated charging rate, the second estimated charging rate is considered the charging rate; and when the first estimated charging rate is less than or equal to the third estimated charging rate, the third estimated charging rate is considered the charging rate.

    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).
