New energy battery fire data ranking

What is the maximum temperature of a new energy vehicle fire?

Due to the high-temperature smoke generated by battery thermal runaway, the plume temperature of new energy vehicle fires was significantly higher than that of fuel vehicles, and the maximum temperature of the ceiling in new energy vehicle fires reached about 220 °C. Fig. 9. Temperature slices with HRR was 3 MW in the tunnel (Z=7.8 m).

Why do EV batteries have a higher fire risk?

This risk is linked to the SOC and capacity of the considered LIB. Cumulated battery bulks and EVs have a lower self-ignition temperature or a higher self-ignition risk. Thus, the fire risk is likely to increase during the collection of batteries and the disposal of EVs [63,64]. Environmental concerns also relate to fire-water run-off.

How dangerous is a battery fire compared to a full-scale EV fire?

Comparatively, the HRR of fire can only increase three orders of magnitude from several kW for a battery cell , to several hundred kW for a single EV battery pack , and several MWs for a full-scale EV fire . So far, there is still a lack of research to scale up the risk and hazard of the small-scale battery fire to full-scale EV fire.

How many MWh of battery energy were involved in the fires?

In total, more than 180 MWh were involved in the fires. For context, Wood Mackenzie, which conducts power and renewable energy research, estimates 17.9 GWh of cumulative battery energy storage capacity was operating globally in that same period, implying that nearly 1 out of every 100 MWh had failed in this way.1

Are batteries a fire risk?

Additionally, there are no doubt potential fire risks during the collection, recycling, treatment and disposal of batteries and EVs. This risk is linked to the SOC and capacity of the considered LIB. Cumulated battery bulks and EVs have a lower self-ignition temperature or a higher self-ignition risk.

How dangerous are new energy vehicle fires?

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.
