Abstract
A battery monitoring apparatus is provided for a secondary battery that produces a change in reaction heat at a predetermined capacity when a storage capacity changes in accompaniment with a current conduction. The battery monitoring apparatus includes: an acquiring unit that acquires, during the current conduction, an impedance change of the secondary battery; and a capacity determination unit that determines, based on the impedance change acquired by the acquiring unit, that the storage capacity of the secondary battery is the predetermined capacity.
