  "textContent": "The present application is to finish charging more accurately in the fully charged state even when electric power is consumed in a system. A power supply circuit supplies, to the system, system power required for the system out of DC power supplied from a power supply, and charges a battery with charging power as the remaining power, and 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 the battery charged state is fully charged, estimates, as a second detection voltage, the cell voltage at the time when determining that the charged state is fully charged based on the cell voltage obtained in a specific charging state to the battery, and updates the predetermined detection voltage from a predetermined first detection voltage to the second detection voltage.",
