Document Type and Number:
WIPO Patent Application WO/2022/131171
Kind Code:
A1
Abstract:
This battery monitoring device is applied to a secondary battery (40) in which a reaction calorie change occurs at a predetermined capacity when an electricity storage capacity changes with energization. The battery monitoring device comprises: an acquiring unit (50) for acquiring a change in the impedance value of the secondary battery during energization; and a capacity determination unit (50) for determining, on the basis of the change in the impedance value acquired by the acquiring unit, that the electricity storage capacity of the secondary battery is the predetermined capacity.
