Abstract:

For the research on safety risk management and control of new energy vehicle power batteries, this paper discusses in detail the failure mechanism and types of power battery systems, clarifies the coupling relationship between battery consistency and safety based on big data statistical analysis, and summarizes the data-driven safety state prediction, fault diagnosis and warning method. Finally, a "vehicle-cloud"-integration-based safety control strategy is proposed for real-vehicle battery systems. This paper aims to provide theoretical guidance for realizing real-time monitoring of battery safety status and risk warning for real vehicles.
