Patent ID: 8604751

Claim:
A charging system for a vehicle for charging a power storage device mounted in the vehicle, said charging system comprising: a charger configured to supply electric power from a power supply external to the vehicle so as to charge said power storage device; and a charge control device for controlling said charger by generating a power command value to said charger, said charge control device including a charge power detection unit for detecting charge power supplied to said power storage device, a target value determination unit for determining a target value of the charge power to said power storage device, a feedback control unit for correcting said target value based on a difference between said charge power and said target value to generate said power command value, a supply power detection unit for detecting supply power output from said charger, and a charge abnormality monitoring unit for, in a case where said charge power is decreased below a first threshold value and said supply power is decreased below a second threshold value, confirming a diagnosis that an abnormality occurs in said charger when said target value falls within an abnormality detectable range, and suspending performing a diagnosis of an abnormality in said charger when said target value is out of the abnormality detectable range.
