Helene and Milton reveal an emerging challenge for first responders: EV batteries catching fire

When a hurricane like Helene or Milton ravages coastal communities, already-strained first responders face a novel, and growing, threat: the lithium-ion batteries that power electric vehicles, e-bikes, and countless gadgets. When exposed to the salty water of a storm surge, they are at risk of bursting into flames — and taking an entire house with them.

“Anything that’s lithium-ion and exposed to salt water can have an issue,” said Bill Morelli, the fire chief in Seminole, Florida, and the bigger the battery, the greater the threat. That’s what makes EVs especially hazardous. “[The problem] has expanded as they continue to be more and more popular.”
