The present invention relates to a life prediction system for an on-board charger. The life prediction system includes: a voltage measurement unit which measures the voltage of a link capacitor included in the on-board charger; and an operation control unit which receives information about the voltage from the voltage measurement unit and generates a signal notifying the point of time for replacement of the on-board charger based on the elapsed set time since the link capacitor started being discharged and the discharged voltage during the elapsed set time. According to the present invention, by predicting the life of the link capacitor of the on-board charger and notifying the point of time for replacement quickly, it is possible to be prepared for a failure of the on-board charger and prevent circuit damage or fire. |
