  • Publication number: 20220229120
    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.

  • Patent number: 11340277
    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.

  • Patent number: 9669782
    Abstract: Discharge of electricity from a drive battery is started, and after a lapse of a predetermined time from the start of supply of electric power to a V2X device or power source apparatus, quick charging contactors are opened (S10-S16) and then failure diagnosis is executed (S18). If a failure is detected, a warning is initiated and restart of the electric power supply is inhibited (S20, S20, S32, S34). On the other hand, if no failure is detected, an open circuit voltage is detected, and the remaining capacity of the drive battery is calculated based on the open circuit voltage (S24-S26). The calculated remaining battery capacity is memorized (S28). Subsequently, the electric power supply from the drive battery to the V2X device or power source apparatus is restarted (S30).
