Abstract
In at least one embodiment, an apparatus for performing a high voltage (HV) short circuit diagnosis and an impedance analysis for a vehicle is provided. The apparatus includes a controller configured to measure a first voltage associated with a battery and a first current that varies based on a HV power net during the pre-charge operation and to perform the short circuit diagnosis based on the first voltage and the first current. The controller is further configured to determine a difference between the first voltage and a pre-charge voltage across one of a capacitor and the HV power net and to measure a second current based at least on the difference. The controller is further configured to perform the impedance analysis for the vehicle based on the second current.
