摘要： PROBLEM TO BE SOLVED: To accurately determine whether or not a vehicle can follow a change in a current command value.SOLUTION: A current value Ia is specified as a current command value for vehicle model discrimination. A charging current value flowing in a vehicle side where the current value Ia has been specified is measured by a current measurement section. If the charging current value (current value AI, current value BI in the figure) that falls within an error range Ix in a measurement range time Tz2 is measured for an effective measurement time Tz1, the charging current value is used to determine whether or not the charging current value can be variably controlled. Specifically, a vehicle model chargeable with the measured charging current value is identified, and whether or not the charging current value can be variably controlled is identified by the vehicle model.

摘要： PROBLEM TO BE SOLVED: To provide a charge control system, applicable for a type of a charging car that performs corrections by temporarily lowering charging current during charging, capable of performing charge control for a charging car by correctly determining complete charge or abnormality occurrence.SOLUTION: A charge control system includes current monitoring means 5 having current detection means for detecting charging current and determination means 6 for determining if charging is complete or abnormal. The current monitoring means 5 calculates an average current value for a certain time or a current value for a short time of the current detected by the current detection means. The determination means 6 determines complete charge if the average current value for a certain time is in the range of a first threshold value or less and a second threshold value or more and stops the charging, or determines abnormal charge if the current value for a short time is less than the second threshold value and stops the charging. A rate of change of the current can be used in combination for the determination.
