Abstract
A circuit includes a power supply circuit which supplies, to a system, system power required for the system out of DC power supplied from a power supply, and charges a battery with charging power as remaining power. When a cell voltage of the battery is a predetermined detection voltage or more and a charging current of the charging power becomes a predetermined detection current or less, the power supply circuit determines that a charged state of the battery is fully charged. The cell voltage at a time when it is determined that the charged state is fully charged based on the cell voltage obtained in a specific charging state to the battery is estimated as a second detection voltage. The predetermined detection voltage is updated from a predetermined first detection voltage to the second detection voltage.
