A method and system of diagnosing a breakdown during pre-charging are provided. The method includes detecting, by a controller, an output voltage of a battery and pre-charging a capacitor of an inverter using energy from the battery. In addition, the controller is configured to measure a voltage applied to the capacitor of the inverter and detect an output current of the battery. A breakdown may then be detected by the controller by collating the detected output voltage, the voltage applied to the capacitor, and the detected output current. |

1. A method of diagnosing a breakdown during pre-charging, comprising:
detecting, by a controller, an output voltage of a battery; pre-charging, by the controller, a capacitor of an inverter using energy from the battery; measuring, by the controller, a voltage applied to the capacitor of the inverter through the pre-charging; detecting, by the controller, an output current of the battery after the voltage is measured; and diagnosing, by the controller, a breakdown by collating the detected output voltage, the voltage applied to the capacitor, and the detected output current. |
