Abstract:
At present, the number of new energy vehicles (NEVs) in other countries is far lower than that in the Chinese market, and there are few cases of fire accidents aboard. Therefore, there is a lack of in-depth and systematic research on NEV accident investigation technology and defect determination technology aboard. At home, based on the accident reporting system of the State Administration of Market Regulation (SAMR), the Defective Product Administrative Center (DPAC) has mastered the most abundant fire accident data of NEVs in China, which lays the foundation for the safety research of NEVs. Based on a real accident case, this paper carries out the research of NEV fault traceability judgment based on power battery voltage, which has important guiding significance for NEV accident investigation.
