This paper describes a study of the high-voltage safety of an electric vehicle under rear impactconditions to ensure that it is in accordance with Chinese regulations. The high-voltage safety has been analyzed and optimizedfrom several perspectives and includes the development of a high-voltage cutoff strategy, assessment of the integrity of thehigh-voltage components after the crash, the layout of the high-voltage and low-voltage cables, and the crashworthiness ofthe structure. This study resolved the high-voltage safety problems that were found in the design phase and thus ensured thatthe vehicle not only meets the requirements of the Chinese regulations, but also meets the high-voltage safety requirementsof US Federal Motor Vehicle Safety Standard (FMVSS) 305 for 80 km/h rear impact.展开更多
