An object is to provide, at low costs, a function for determining whether a monitoring section should execute a self-diagnosis. A monitoring system has a monitoring section for acquiring information on the charge and discharge state of an electric storage device and a determination section for determining the charge and discharge state of the electric storage device on the basis of information acquired by the monitoring section. The determination section has an output section for continuously outputting, to the monitoring section, a stepped signal made up of a High signal and a Low signal, and as well, when the charge and discharge state of the electric storage device has been determined to fall within an allowable range on the basis of the information acquired from the monitoring section, outputs a diagnosis permit signal that is a unique stepped signal having a period different from that before the determination, and when the signal received from the determination section has been determined to be the diagnosis permit signal, the monitoring section executes a self-diagnosis for detecting an abnormal event in the monitoring section. |
