Abstract: A driver controls a switch inserted in a current path between a secondary battery and an inverter that drives a motor. A first abnormality detector instructs the driver to turn off the switch when an abnormality of the secondary battery is detected. A second abnormality detector is disposed in parallel with the first abnormality detector, and instructs the driver to turn off the switch when the abnormality of the secondary battery is detected. The first abnormality detector suspends an instruction to turn off the switch to the driver, even when the abnormality of the secondary battery is detected, in cases where an ECU instructs discharge-stop prohibition of the secondary battery. The second abnormality detector instructs the driver to turn off the switch after a lapse of a certain time from when the abnormality of the secondary battery is detected, regardless of an instruction from the ECU.

Abstract: Battery controller chooses as a standard storage battery Bs one of the storage batteries which has the lowest voltage in storage batteries B1 to Bn. Battery controller obtains as a standard voltage Vs a voltage of the standard storage battery Bs, and obtains as a standard SOHs an SOH of the standard storage battery Bs. Battery controller specifies from storage batteries B1 to Bn a storage battery to be discharged by equalizing unit 450 based on a magnitude relation between an SOHj of each of the storage batteries and the standard SOHs and based on a voltage difference between the terminal voltage of each of the storage batteries and the standard voltage Vs. Battery controller performs an equalizing process by causing equalizing unit to discharge the specified storage battery.
