This charge control device controls a charging stage of a power storage unit, which stores power supplied from a power supply, and which supplies the stored power to a load. The charge control device is provided with a voltage monitoring unit, which determines that the power storage unit is in a charged state when a voltage between the terminals of the power storage unit is a predetermined upper limit voltage or higher, and which determines that charging is necessary when the voltage between the terminals of the power storage unit is a predetermined lower limit voltage or lower, said predetermined lower limit voltage being lower than the predetermined upper limit voltage. When the voltage monitoring unit determines that the charging of the power storage unit is necessary on the basis of the fact that the voltage between the terminals of the power storage unit is the predetermined lower limit voltage or lower due to a voltage drop generated in the power storage unit due to resistance components and a load current in the power storage unit when the load is being driven by means of power supplied from the power storage unit, the power storage unit is charged with power from the power supply, and the voltage between the terminals of the power storage unit is set to the predetermined upper limit voltage or higher. |
