摘要： A battery module includes: a battery cell unit including a plurality of battery cells connected together in series or series-parallel; a cell monitoring unit configured to monitor temperatures and voltages of the battery cells; and a plurality of overtemperature/overvoltage detecting units of n systems (n: an integer greater than or equal to 2). The overtemperature/overvoltage detecting units of the n systems are configured to independently detect an overtemperature or an overvoltage of the battery cells as an abnormal state, and to mutually notify one another of results of the detection. Each of the overtemperature/overvoltage detecting units is configured to, upon being notified that the abnormal state is detected from another overtemperature/overvoltage detecting unit of another system in the battery module, operate on the assumption that the overtemperature/overvoltage detecting unit detects the abnormal state.

The counter counts, for communication lines to which a plurality of battery modules are connected to form communication channels, the number of battery modules connected to each of the communication lines. The serial information setter sets a series of pieces of information about the battery modules connected to the plurality of communication lines as information for identifying the battery modules on the basis of the number of battery modules counted by the counter. The information transmitter transmits, to an external apparatus, management information in which status information of each of the battery modules is associated with each piece of the series of pieces of information set by the serial information setter.

摘要： A storage battery management device includes a connector, storage, a drive voltage controller, a determiner, and a current sensor controller. The connector is connectable to a current sensor. The storage stores current sensor information including an output range of normal output values and each current-sensor type indicating a type of a current sensor connectable to the connector in association with each other. The drive voltage controller causes a current to flow through a current sensor while varying a voltage to be applied to the current sensor. The determiner determines, based on whether an output value that is received via the connector from the current sensor falls in the output range corresponding to the current-sensor type, the current-sensor type of the current sensor connected to the connector. The current sensor controller controls the current sensor in accordance with the determined current-sensor type.

摘要： A storage battery management device manages a plurality of battery units in a storage battery system including the battery units having a plurality of battery cells and a power adjustment device connected to the battery units via respective contactors and connected to a main circuit. The storage battery management device includes a minimum value determination unit and a controller. The minimum value determination unit, from the battery units in which a difference between a maximum cell voltage and a minimum cell voltage of the battery cells forming each of the battery units is equal to or less than a certain value, determines a minimum value of the minimum cell voltage. The controller controls a cell balance process of the battery unit managed by itself, by using the minimum value of the minimum cell voltage determined by the minimum value determination unit as a cell balance target voltage.

摘要： A backup power supply system includes a secondary battery, an interface unit, a charging and discharging control unit, a detection unit, a remaining capacity estimating unit, a deterioration estimating unit, and a notification unit. The interface unit transmits a trigger signal based on an operation of a user. The charging and discharging control unit performs control of discharging the secondary battery and then charging the secondary battery or control of charging the secondary battery and then discharging the secondary battery when the trigger signal is received from the interface unit. The detection unit detects a voltage of the secondary battery at different timings. The remaining capacity estimating unit estimates a remaining capacity of the secondary battery based on the voltage of the secondary battery. The deterioration estimating unit estimates a deterioration state of the secondary battery based on the estimated remaining capacity. The notification unit outputs the estimated deterioration state.
