This paper aims to study the causes,key influencing factors,and failure modes of fire accidents in new energy passenger vehicles from a holistic perspective,and to supplement the causes of fire accidents beyond battery-related issues based on user usage scenarios,and identify preventive solutions.In this paper,an in-depth statistical analysis is conducted on fire accidents involving new energy vehicles from 2021 to 2022.The user scenarios and the root causes of these fire accidents are summarized.The failure modes at a deeper level and the causes of some typical accident cases are analyzed.The prevention of fire accidents at the design level is discussed.Several solutions are provided,and discussions are held on the research direction of vehicle safety for new energy vehicles.
