CHARGING SYSTEM FOR VEHICLE AND METHOD FOR CONTROLLING CHARGING SYSTEM

A charge control device includes a charge power detection unit (52) for detecting charge power supplied to a power storage device; a target value determination unit (51) for determining a target value of the charge power to the power storage device; a feedback control unit (54) for correcting the target value based on a difference between the charge power and the target value to generate the power command value; a supply power detection unit (61) for detecting supply power output from the charger; and a charge abnormality monitoring unit (62) for, in a case where the charge power is decreased below a first threshold value and the supply power is decreased below a second threshold value, confirming a diagnosis that an abnormality occurs in the charger when the target value falls within an abnormality detectable range, and suspending performing a diagnosis of an abnormality in the charger when the target value is out of the abnormality detectable range.
