A charge control circuit for controlling charging of a plurality of batteries includes switching elements respectively connected in parallel to the batteries, and a charge control device for reducing charging current to the respective batteries. The charge control device converts voltages of the respective batteries into multiple converted battery voltages based on a predetermined reference voltage as a reference on the basis of voltages at both ends of the respective batteries, generates an offset battery voltage obtained by adding a predetermined offset voltage to the converted battery voltages, compares each converted battery voltage with the offset battery voltage, and reduces charging current to the corresponding battery by turning on the switching element connected in parallel to the corresponding battery when the each converted battery voltage is higher than the offset voltage.
