Abstract
A secondary battery monitoring device is equipped with a resistance circuit and a detection circuit detecting an abnormality of a secondary battery, a current generation circuit generating a failure detection circuit for setting an output terminal of the resistance circuit to a failure diagnosis voltage, and a switch which permits the failure detection circuit to flow to the output terminal of the resistance circuit by switching. Further, a method for diagnosing failure of the secondary battery monitoring device is provided.
