Hurricanes Highlight Fire Risks of EV Batteries in Flooded Areas

Electric vehicle batteries can catch fire when exposed to salt water, posing a challenge for first responders during storms.

Hurricanes Helene and Milton have underscored the fire risks associated with lithium-ion batteries in electric vehicles when submerged in salt water.
First responders face difficulties extinguishing these fires due to the unique chemical reactions and high temperatures involved.
Although EV battery fires are rare, the risk is significant enough that authorities advise moving vehicles to higher ground before storms.
The chemistry of lithium-ion batteries makes them prone to 'thermal runaway,' a process that can lead to uncontrollable fires.
Efforts are underway to improve battery safety, including research into alternative battery designs that could better withstand salt water exposure.
