Firefighters in Florida have a new challenge in cleaning up in the aftermath of Hurricane Ian: spontaneous car fires in electric vehicles whose batteries corroded because of storm flooding.

Florida Chief Financial Officer (CFO) Jimmy Patronis warned Thursday that corroding batteries are resulting in a rash of spontaneous fires, WEAR reports.

He shared video of Naples firefighters working an electric vehicle fire. Patronis also noted that there are “a ton of EVs disabled from Ian.”

Florida is second in the nation in terms of electric vehicle usage, following only California in the numbers of electric vehicles on the road.
