Abstract
A full charge sensing apparatus for sensing a fully charged state of a secondary battery based on an equivalent circuit model of the secondary battery includes a measuring unit that measures a voltage and a current during charging of the secondary battery, a learning unit that performs a learning process on a plurality of parameters in the equivalent circuit model using a result of measurement of the measuring unit, and a determining unit that determines that the secondary battery is in a fully charged state in a case where, among the parameters on which the learning process has been performed by the learning unit, a parameter corresponding to a reaction resistance of the secondary battery is greater than a predetermined threshold.
