Speech Title: Fire safety issues and countermeasures for the battery system of new energy vehicles

Abstract:

In recent years, the frequent fire accidents of new energy vehicles have greatly reduced consumer confidence in purchasing. The cause of fire accidents is often attributed to the failure to detect the fault of battery system early and take reasonable countermeasures, and then allow the fault to gradually evolve to the thermal runaway of the battery system. Safety monitoring, fault diagnosis and risk assessment of battery systems have become current research hotspots and difficulties. This report focuses on the fire safety problems and countermeasures of the battery system of new energy vehicles. It describes: 1) Multi-dimensional statistical laws of battery system fire accidents; 2) Potential failure modes, inducements and failure modes of the battery system; 3) Fault diagnosis approaches of the battery system; 4) Countermeasures for thermal runaway of battery system; 5) Comment on relevant safety test standards of battery system.
