Abstract:
1. A charge control circuit, comprising: a charge control unit that controls an operation of a charging unit that charges a rechargeable battery; a voltage detection unit that detects a terminal voltage of the rechargeable battery; and a current detection unit that detects a current flowing in the rechargeable battery, wherein when a current value detected by the current detection unit exceeds an anomalous current threshold value set to a value that exceeds a current value requested to the charging unit, and when the terminal voltage of the rechargeable battery as detected by the voltage detection unit is equal to or greater than a second threshold-value voltage that is set beforehand to a voltage value lower than a full charge voltage being a terminal voltage at a time when the rechargeable battery is in full charge, the charge control unit carries out a first anomaly response process of requesting, to the charging unit, a charge voltage of the second threshold value voltage, and of carrying out the constant voltage charging through supply of that charge voltage to the rechargeable battery.
