Patent ID: 8466655

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 first 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, a guard target value determination unit for determining a guard target value corresponding to an upper limit value of said power command value based on allowable power of a system for charging, a second feedback control unit for correcting said guard target value based on a difference between said supply power detected by said supply power detection unit and said guard target value, and an upper limit guard processing unit for limiting the target value corrected by said first feedback control unit based on the guard target value corrected by said second feedback control unit.
