摘要： 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.

摘要： This disclosure relates to a battery assembly of an electrified vehicle, and in particular to a battery pack with a vent gas passageway. An example battery assembly includes a battery array having a plurality of battery cells. Each of the battery cells includes a vent configured to release vent gas from a respective one of the battery cells. Further, the battery assembly includes an enclosure assembly surrounding the battery array, and a vent gas passageway within the enclosure assembly. The vent gas passageway includes a plurality of inlet ports, and each of the inlet ports is substantially aligned with a respective one of the vents.
