Semiconductor device, battery pack, and electronic device
A semiconductor device generates battery state information including information of a capacity that can be extracted from a battery in the case of discharging from a full charge state until a discharge cutoff voltage at a predetermined discharge rate, based on measurement results of battery voltage, current, and temperature. The device calculates a first estimate value of capacity that can be extracted in the case of discharging the battery from the full charge state until the discharge cutoff voltage and calculates a second estimate value of capacity that can be extracted in the case of discharging the battery until a voltage larger than the discharge cutoff voltage.
