Abstract: An abnormality determination device for a secondary battery includes an internal-resistance calculation unit, a threshold memory unit, a capacity balance comparison unit, and an abnormality determination unit. The internal-resistance calculation unit detects an internal resistance in a negative-electrode reaction resistance dominant region in which a reaction resistance of a negative electrode is dominant in a charge and discharge reaction of the secondary battery. The threshold memory unit stores a capacity balance threshold used as a reference for determining abnormality in a balance between a capacity of a positive electrode and a capacity of the negative electrode in the secondary battery. The capacity balance comparison unit compares the internal resistance calculated by the internal-resistance calculation unit with the capacity balance threshold stored in the threshold memory unit. The abnormality determination unit determines abnormality in capacity balance in the secondary battery based on a comparison result from the capacity balance comparison unit.

Abstract: A degradation degree assessment device for a secondary battery is to assess a degree of degradation of a secondary battery and includes a battery characteristic acquisition unit, a capacity estimation unit, and an assessment unit. The battery characteristic acquisition unit acquires a battery characteristic relating to a voltage transition of the secondary battery in a predetermined voltage section. The assessment unit assesses the degree of degradation of the secondary battery based on the battery characteristic acquired by the battery characteristic acquisition unit or based on a battery characteristic-related value computed on the basis of the battery characteristic.

Abstract: A server for a deterioration degree determination system for a secondary battery includes an estimation formula memory unit and an update unit. The estimation formula memory unit stores an estimation formula for determining a deterioration degree based on a battery characteristic related to transition of a battery state over a predetermined voltage section in the secondary battery or a battery characteristic relationship value related to the battery characteristic. The update unit that updates the estimation formula stored in the estimation formula memory unit based on the battery characteristic related to the transition of the battery state of the secondary battery acquired by charging and discharging the secondary battery in an external terminal.

Abstract: In a deterioration degree determination device for a secondary battery, a battery information acquisition unit acquires battery information related to the secondary battery, and a feasibility determination unit determines feasibility of determination of deterioration degree for each secondary battery based on the battery information and a feasibility determination reference prepared in advance. A battery characteristic acquisition unit acquires a battery characteristic related to transition of a battery state in a predetermined voltage section for the secondary battery for which the determination of the deterioration degree is determined to be feasible by the feasibility determination unit. A deterioration degree determination unit determines the deterioration degree of the secondary battery for which the determination of the deterioration degree is determined to be feasible, based on the battery characteristic acquired by the battery characteristic acquisition unit or a battery characteristic relationship value calculated based on the battery characteristic.

Abstract: A used secondary battery module management system server manages a manufacture of a battery assembly. The server stores, in a memory, a correspondence relationship of each of secondary battery modules among identification information, ranks, and status information. The server extracts an available rank from the ranks in response to a rebuilding request for the battery assembly. The available rank is a rank in which the number of the secondary battery modules having the status information indicating that the secondary battery modules are available is equal to or larger than the number of the secondary battery modules required to constitute the battery assembly. The server receives, from an external terminal, the identification information on each of selection secondary battery modules having an identical rank.
