In a charging control apparatus, a supply power requestor requests an external power source to output supply power having a constant voltage and a constant current. A voltage conversion instructor instructs a voltage conversion device to perform voltage conversion of the supply power from the external power source such that converted supply power has a charging voltage and a charging current that are respectively within allowable charging-voltage range and allowable charging-current range. The voltage conversion instructor instructs the voltage conversion device to output the converted supply power to the power storage to thereby charge the power storage.
