“The NTSB data said that after 41 fatal collisions involving BEVs, 1 caught on fire (2.44%). The NTSB data said that after 20,315 fatal collisions involving gasoline vehicles, 644 caught on fire (3.17%). The NTSB data said that after 543 fatal collisions involving gasoline hybrid vehicles, 12 caught on fire (2.21%),” Conway said.
“But 41 crashes vs 20,315 crashes vs 543 crashes make it statistically irresponsible to compare these numbers. For example, if there was a 42nd crash with an EV and it caught on fire then it would be 4.76% of EVs or double the rate of hybrids. Until the sample size is the same and significant we just can’t say which will be worse or not,” Conway said.
Richard Billyeald, chief technical officer at Britain’s Thatcham Research, said EVs generally appear less likely fire risks, but the data is limited.
“Our latest research indicates that the risk of a fire for all types of EV remains less likely than for ICE vehicles. It should be noted that the usable data only goes back five years and even now the number of EVs on the roads still represents a very small sample size. This is also reflected in the safety testing we conduct in the U.K. on behalf of Euro NCAP (European auto safety), where
despite the robust impacts to the front and particularly the sides of the vehicle where the battery is most vulnerable, there have been no resultant thermal events,” Billyeald said.
The fire risk from electric cars appears to be less than for conventional vehicles, although any firm conclusions are not yet possible because there is not enough data to decide that pure electric cars are more prone to spontaneous fire than internal combustion engine ones.
