Abstract: A charging apparatus includes: a first conversion circuit that converts alternating-current power supplied from an external power supply into direct-current power; a second conversion circuit that converts an output voltage from the first conversion circuit into a voltage for a battery and supplies the voltage to the battery; and a controller configured to change charging power to be supplied to the battery by controlling the first conversion circuit and the second conversion circuit when the output voltage falls outside a predetermined reference range, and to determine whether the output voltage in the changed charging power falls within the reference range. When the output voltage falls outside the reference range, the controller controls the first conversion circuit and the second conversion circuit such that the charging power decreases stepwise until the output voltage falls within the reference range.
