There is NO reliable data around battery fires. If you dig into the data, it is all collected from newspaper headlines. So when EV enthusiasts tell you that the fire are rare, they really don't know that.
The National Institute of Standards and Technology (NIST) looked into that problem. Understanding the Risk of Lithium-Ion Battery Fires. This report is from March of this year.
Lithium ion battery (LIB) fires are a growing problem that extends across the supply chain, including mining, production, warehousing, shipping, and waste disposal, as well as the consumer side. But data on such fires is fragmented and mostly incomplete. Many are secondary data sources, and for the National Fire Incident Reporting System (NFIRS) and the Consumer Product Safety Commission data sets identification of LIB fires is difficult.
Now the NIST report is a PDF of government-produced bureaucratic speak. That said, it is remarkably readable. It is mostly a statement of the problem. We don't have the data. It is hard or impossible for firefighters to collect some of the data. etc. In short, the data we do have is questionable.
The easiest way to come to an understanding of the problem is to watch the 7 minute video below.
