Abstract
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.
