Abstract
A charging control device includes a charging current control unit which sets a target value (Isp) of a charging current from an external power supply to a high-voltage battery, a charging current adjusting circuit which adjusts the charging current to the Isp, a supply voltage sensor which detects a supply voltage from the external power supply to the high-voltage battery, and a supply voltage monitoring unit which detects or predicts presence or absence of a decrease in the supply voltage from a predetermined normal charging voltage using an output of the supply voltage sensor, where when the decrease is not detected or predicted, the Isp is set to a predetermined normal target value, and when the decrease is detected or predicted, the Isp is changed to be equal to or lower than the normal target value and maintained at a value at which the supply voltage reaches a determination voltage.
