New energy vehicle fires were developing rapidly. Once a fire occurs in the lithium-ion battery in the vehicle, the high-temperature smoke and CO, etc. seriously endangered the safety of people inside the vehicle and the tunnel. It would reach a very dangerous situation in a short time.
Once the onboard battery involved in fire, there is a greater difficulty in suppressing EV fires, because the burning battery pack inside is inaccessible to externally applied suppressant and can re-ignite without sufficient cooling.
Fires in full EV battery packs, containing thousands of cells, are far more complex, involving chain reactions and additional energy release from the vehicle itself. Our analysis did, however, reveal notable differences in fire behaviour between NMC and LFP batteries as capacity increases.
fire starts in the battery p ower system (Figure 1). In terms of propulsion, the battery capacity can be analogized to the gasoline capacity in an ICEV's fuel tank. Therefore, the EV fire is connected with the fire risk and hazard asso ciated with the battery cell and power system, as well as, the size and capacity of the battery pack. In general,
