Outline
To address the adaptability bottlenecks of traditional automotive-grade chip mission profile frameworks in the context of high-voltage electrification and the large-scale deployment of wide-bandgap devices in new energy vehicles, this paper conducts a systematic review of the theoretical framework, standardization paradigms, load parameter discrepancies, reliability assessment models, and engineering application boundaries of automotive chip mission profiles, based on AEC-Q100 Rev-J. The fundamental differences in chip loading characteristics between conventional fuel vehicles and new energy vehicles are comparatively analyzed across multiple dimensions. The study reveals that the thermal load duration of chips in new energy vehicles is approximately 10 times longer than that in fuel vehicles, with operating voltages reaching 800 V and power device switching frequencies increasing by approximately 20 times. Traditional automotive chip reliability assessments are inadequate for new energy vehicles, failing to address multi-physics coupling, long-term aging, and the unique failure mechanisms of wide-bandgap devices. Currently, the reliability certification of automotive-grade chips is shifting from "general compliance demonstration" to "application suitability demonstration". In the future, constructing refined, dynamic, and multi-scale mission profiles, along with improving the suitability assessment system for wide-bandgap devices, will become critical directions requiring breakthrough in this field.
