Saltwater Risk for EVs

author: FutureCar Staff    

Electric vehicle owners in Florida are now on high alert following Hurricane Idalia, as the storm brought saltwater into contact with their vehicles. The Palm Harbor fire department recently issued a warning to hybrid or electric vehicle owners, advising them to relocate their vehicles from their garages if they had been exposed to saltwater. This warning came after a Tesla car caught fire in Dunedin.

The fire department explained that saltwater exposure can trigger combustion in lithium-ion batteries, urging people to move their vehicles to higher ground if possible. The warning also extended to golf carts and electric scooters, with the department advising against driving these vehicles through water.

Tampa fire rescue further explained that when EV batteries are damaged by saltwater, a chemical reaction called thermal runaway occurs within the cells. This reaction causes the batteries to heat up and increases the risk of fires.

Tesla, the electric vehicle manufacturer, also provided recommendations for owners. They advised users to move their vehicles to a location that is not at risk or to higher ground if there is a risk of submersion. In the event of exposure to saltwater, Tesla recommends treating the vehicle as if it has been in an accident and contacting the insurance company. They also advise against operating the vehicle until it has been inspected.

If owners notice any signs of fire, smoke, audible popping/hissing, or heating coming from their vehicles, Tesla advises them to step away and immediately contact their local first responders.
