CHARGING SYSTEM FOR VEHICLE AND METHOD FOR CONTROLLING CHARGING SYSTEM
First Claim
1. 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 includinga 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, anda 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.

Abstract
A charge control device includes a charge power detection unit for detecting charge power supplied to a power storage device; a target value determination unit for determining a target value of the charge power to the power storage device; a feedback control unit 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 for detecting supply power output from the charger; and a charge abnormality monitoring unit 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.

5. A method for controlling a charging system for charging a power storage device mounted in a vehicle,
said charging system including 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, and 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 target value and said charge power to generate said power command value, and a supply power detection unit for detecting supply power output from said charger, said method comprising the steps of: -
determining whether said charge power is decreased below a first threshold value and said supply power is decreased below a second threshold value; and 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 to shut down a system when said target value is out of the abnormality detectable range.
