Abstract
A system is provided with which data on the internal state of a storage battery such as SOC-OCV characteristics and FCC can be obtained with high accuracy and highly accurate estimation is possible even in the case of repeating charging and discharging for a long period. The storage battery management system includes a vehicle that includes a unit enabling data transmission and reception; the vehicle includes a storage battery, a balancing circuit electrically connected to the storage battery, and a vehicle control unit having a function of controlling the balancing circuit; the storage battery includes an assembled battery including a plurality of battery cells; the vehicle control unit has a function of selecting an estimated value that most closely shows a state of each of the battery cells included in the assembled battery; and the balancing circuit has a function of being controlled in accordance with the selected estimated value.
