Abstract: At present, China's new energy vehicle ownership and production and sales volume rank first in the world, with a clear trend of rapid growth. However, the high accident rate and prominent operational safety hazards of new energy vehicles, which affect the safety of people's lives and property, are mostly attributed to the safety hazards in the three major components or entire vehicle parts of electric vehicles, and have not been adjusted correctly. To accurately monitor the working status of battery components, motor components, electronic control components, and the entire vehicle in real-time, the failure mechanisms of common safety hazards of each component and the vehicle are clarified through literature analysis, and the corresponding safety characteristic parameters of each component and the vehicle are determined, providing scientific indicators for the correct and rapid detection of safety hazards. By monitoring the safety characteristics of each component and the entire vehicle in real-time, the working status of each component and the vehicle can be understood in advance, and the faulty components can be accurately identified, improving the risk identification level of electric vehicles, and providing the possibility for timely and rapid correct regulation of electronic control units in new energy vehicles.
