Beschreibung
Zusammenfassung:	A battery monitoring device monitors a battery. The battery monitoring device includes a deterioration detection unit that detects a physical quantity having a higher correlation with a capacity deterioration of the battery than a voltage and a current of the battery, and a capacity ratio estimation unit that estimates a capacity ratio of the battery based on the physical quantity.
