PROBLEM TO BE SOLVED: To provide a charge current control circuit capable of suppressing a switching element provided for preventing overcharging of a storage battery from being frequently switched, even when the temperature of the storage battery in an almost fully charged state drops.SOLUTION: A charge current control circuit 1 for controlling a charge current Ichg supplied from solar batteries PV1, PV2 to a storage battery BAT is provided with a voltage measurement unit 10 for measuring the voltage of the storage battery, a temperature measurement unit 20 for measuring the temperature of the storage battery, and a current control unit 30. The current control unit 30 controls the charge current Ichg in accordance with the voltage measured by the voltage measurement unit 10 and the temperature measured by the temperature measurement unit 20. |
