CHARGING DEVICE FOR POWER STORAGE DEVICE AND VEHICLE MOUNTED WITH THE SAME
First Claim
1. A charging device for charging a power storage device, comprising:
- an electric power feeding device configured to feed charging power to the power storage device, using electric power from a power supply; and
a control device configured to set a charging start time using an estimated charging time in accordance with a charging end time which is input by a user, and to cause the electric power feeding device to perform a charging operation of charging the power storage device,the control device configured to perform learning control for a parameter relevant to a factor which affects estimation of the charging time, and to estimate the charging time using a learned value of the parameter under the learning control,the parameter including a parameter relevant to a state of degradation of a charging capacity of the power storage device, and the parameter being determined based on a reference amount of electric power with which the power storage device in a state of charge before start of a charging operation is chargeable, and an actual amount of electric power with which the power storage device could be charged actually.

Abstract
A vehicle includes a power storage device, an electric power feeding device, and an ECU, with the power storage device chargeable with electric power from an external power supply. The ECU sets a charging start time using an estimated charging time in accordance with a scheduled charging end time which is input by a user, and uses the electric power feeding device to start a charging operation of charging the power storage device in response to the fact that the charging start time is reached. The ECU performs learning control for a parameter relevant to a factor which affects estimation of the charging time, and estimates the charging time using a learned value of the parameter under the learning control. In this way, the accuracy in estimation of the charging time can be enhanced.
