Charging control apparatus
First Claim
1. A charging control apparatus mounted on a vehicle connected to an external charging device through a charging connector, for performing control related to charging, comprising:
- a voltage detection unit for detecting a charging voltage applied to said charging connector; and
an abnormality determination unit for estimating, based on variation in voltage detected by said voltage detection unit during a predetermined period of time after said charging connector is connected to said vehicle, variation in the charging voltage applied to said charging connector after a lapse of said predetermined period of time, and determining that a failure has occurred in said external charging device if a degree of separation between the variation in voltage detected by said voltage detection unit after the lapse of said predetermined period of time and the estimated variation in voltage is larger than a predetermined value.

Abstract
A charging control apparatus mounted on a vehicle connected to an external charging device through a charging connector, for performing control related to charging, includes a voltage sensor for detecting a voltage applied to the charging connector, and a control device for estimating, based on variation in voltage detected by the voltage sensor during a predetermined period of time after the charging connector is connected to the vehicle, variation in voltage applied to the charging connector after a lapse of the predetermined period of time, and determining that a failure has occurred in the external charging device if a degree of separation between the variation in voltage detected by the voltage sensor after the lapse of the predetermined period of time and the estimated variation in voltage is larger than a predetermined value.
