    摘要： Disclosed is a main relay monitoring system and method for a green vehicle, where a main relay is installed between a high voltage battery and an inverter in order to diagnose whether the main relay, which controls the output of the high voltage battery, is fused. In particular a switching operation of an inverter is stopped when an ignition off is detected, and a main relay is turned off and a voltage output of a main battery is cut. Then, a voltage charged at a DC link capacitor is forcibly discharged once the main relay is completely turned off. A voltage of the main battery is then compared to an input voltage of the inverter, and a determination is made based off of this comparison whether the main relay is fused.
