充電自動車への充電制御システム

Japanese Patent JP5467646

B2

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.
