No less than six property caught fire from inside the Florida immediately after floodwaters off Hurricane Helene immersed digital vehicles (EV) battery packs and you may ignited them, state chief financial administrator and you can fire marshal Jimmy Patronis said on the Oct. 2.
Ron DeSantis from inside the Madeira Beach, Fl, Patronis said that county authorities have observed 16 fireplaces to date out-of EVs from the Tampa Bay area by yourself, in addition to Pinellas State.
The fresh new governor had informed EV customers in Florida to get their vehicle to better surface ahead of Helene’s arrival, because the exposure to saltwater can also be brief-circuit the electric batteries, resulting in a disastrous strings impulse known as thermal runaway where heat energy is released from the battery result in a flames.
During a news conference with Gov
One of many risks that we are really concerned with is lithium-ion battery tech-which is EVs, golf carts, and you can scooters. The unit do not combine well with saltwater, Patronis told you.
The vehicles catch flame pursuing the short circuit develops ranging from numerous tissue in the lithium electric battery, explained Tom Barth of Federal Transportation Security Panel.
In case the saltwater might be able to link brand new gap involving the positive and negative terminals regarding [the] battery pack, then it can cause a short circuit, Barth said, who is chief of the special assessment branch of board’s Workplace out of Road Safety.
The technology are apparently about simply saltwater, once the thermal runaway was not seen in EVs regarding freshwater ton into the California.
When Hurricane Ian cut through Charlotte Harbor, Florida, when you look at the 2022 within Group cuatro power, having restrict sustained wind gusts away from 150 mph, they delivered upward of 15 foot of violent storm increase to your servings off americash loans Leeds Charlotte, Collier, and you may Lee Areas, reducing as many as 5,000 EV battery packs and you will igniting thirty six of these.
During the time, Patronis told you when you look at the a summary of the fresh new societal system X: Last week, We seen an enthusiastic EV flames through the Hurricane Ian operations. Firefighters put out the latest fire, then it create reignite.

The fresh institution told you the original instances of EV fireplaces for the reason that saltwater happened while in the Hurricane Sandy within the 2012, when the violent storm surge deluged parts of Newark, Nj, one of other places.
Lithium-ion vehicle electric battery fireplaces was basically seen one another easily igniting and igniting few weeks immediately following electric battery ruin taken place. This new timing of fire initiation are certain on battery build, chemistry, and you can problems for the battery package, according to the NHTSA. Like with other forms out-of power supply destruction, the period of time for this change regarding mind-temperatures in order to flame ignition can vary.
The fresh company added recommendations you to definitely people broken auto with an excellent lithium-ion electric battery should not be left inside otherwise within 50 legs of every structure, automobile, or combustibles.
Towards the Sept. 29, Patronis advised people EV residents who possess knowledgeable flood so you can instantly phone call their insurance firms and have the vehicles towed so you can a great secure length, particularly when their strength might have been turned-back on, which can begin the fresh thermal runaway procedure.

Even in its lack of those cues, people is recommended to name the insurers if h2o has actually attained the newest automobile’s battery which can also be go through a safety check. Getting Tesla residents, Tesla Service can give a review, and you may Tesla Roadside Guidelines can tow the car in order to a safe 50-foot point of any structures and other auto.
