Abstract
Systems devices and methods are disclosed for detecting DC arc faults in a high voltage vehicle electrical distribution system. An example vehicle includes a high voltage electronic system comprising a current sensor configured to capture current data and a processor. The processor is configured to generate filtered data by applying a filter to the current data, determine a Hurst exponent based on the filtered data, and responsive to determining a threshold change in the Hurst exponent, detect the presence of a DC arc in the high voltage electronic system.
