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.

摘要： According to one embodiment, a wiring diagnostic apparatus of embodiments includes a counter, an acquirer, and an abnormality determiner. The counter counts the number of battery modules connected to a plurality of first communication lines to which a plurality of battery modules are connected to form a communication channel for each of the first communication lines. The acquirer acquires identification information for identifying a battery module connected to a corresponding second communication line among battery modules connected to a plurality of second communication lines each forming a communication channel with a first communication line via the second communication line. The abnormality determiner determines an abnormality in a wiring relationship of the first communication line or the second communication line on the basis of the number of battery modules counted by the counter and identification information acquired by the acquirer.

摘要： According to one embodiment, a storage battery device includes a battery group, a charge-and-discharge control FET unit, and a drive controller. The battery group includes a plurality of battery cells connected in series. The charge-and-discharge control FET unit is connected to a low potential side of the battery group and includes at least a pair of N-channel MOSFETs source terminals of which are back-to-back connected. The drive controller outputs a drive control signal to a gate terminal of the respective N-channel MOSFETs included in the charge-and-discharge control FET unit. The drive control signal is generated based on a potential level of the source terminals.

摘要： According to one embodiment, a cell monitoring device that performs monitoring of a cell module under control of a battery management device (BMD), includes a communication controller and a control device. The communication controller is capable of being connected to BMD through a communication line. The control device performs an activation processing of the communication controller at a time of initialization, and controls the cell monitoring device. The control device performs a reboot processing of the communication controller in a period shorter than a period of detecting an error condition of the communication controller by BMD when a second voltage drops to be below an operation allowable voltage of the communication controller in a state in which a first voltage is above a certain operation allowable voltage. The first voltage represents a power supply voltage of the control device. The second voltage represents a power supply voltage of the communication controller.
