Abstract
Provided is a battery monitoring system that has a high level of safety even under a state in which characteristics of a reference voltage circuit are deteriorated. The battery monitoring system has a configuration in which: a reference voltage of a first battery monitoring IC is monitored by a second battery monitoring IC; and the second battery monitoring IC outputs, when detecting that the reference voltage reaches a value falling outside a predetermined range, a signal indicating an abnormality of the reference voltage to the first battery monitoring IC, and the first battery monitoring IC stops monitoring of a battery when the signal indicating the abnormality of the reference voltage is input to the first battery monitoring IC.
