Abstract
Provided is a battery state monitoring circuit and a battery device capable of predicting a state of charge of a secondary battery with high accuracy. The battery state monitoring circuit includes a pseudo-equivalent circuit of the secondary battery, and causes a current flowing through a sense resistor to flow to the pseudo-equivalent circuit of the secondary battery, to thereby measure a pseudo-open circuit voltage of the secondary battery.
