As new energy carriers make their way into the market, some misconceptions will naturally also make their way to the public. The objective of this report is to respond to some of the most common misconceptions and myths regarding battery electric vehicle (BEV) fires, while highlighting the latest research and available data as of April 2022.
Furthermore, increased fire risks related to lithium-ion batteries (LIBs) are often pointed out, even though most fire incidents involving EVs have fire origins other than the traction battery.

For a Li-ion battery fire, it is concluded that oxygen consumption calorimetry will exclude internal heat generation and underestimate the total heat released from the external flaming fire by up to 10 %. In addition, high rate of combustion reactions can result in that the measured peak heat release rate is underestimated much more, up to 100 %.
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.
This paper reviews these fire risks as well as accidents involving EVs, that are powered by the battery, especially the LIB. The limited large-scale fire tests of EV and the corresponding fire-protection strategies are also reviewed in detail. Figure 1.
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.
