EV House owners Warned About Hurricane Helene Saltwater Flooding Posing Critical Hearth Dangers : Automotive Addicts
Automotive
As Hurricane Helene leaves behind unlucky destruction all through the east of the US, electrical automobile (EV) homeowners are being warned a few severe but usually ignored hazard, the chance of fires attributable to saltwater flooding. Florida officers, together with Governor Ron DeSantis, suggested EV drivers to maneuver their automobiles to larger floor final week in preparation for the storm. Whereas fires associated to electrical automobiles are uncommon, the mixture of saltwater and EV batteries can create hazardous circumstances if preventive steps aren’t taken.
Why Saltwater Is a Risk to EVs
Not like conventional gas-powered automobiles, electrical automobiles depend on lithium-ion batteries that, underneath sure circumstances, can catch fireplace. Saltwater, resulting from its skill to conduct electrical energy, poses a novel danger to those batteries, particularly if the water manages to penetrate the protecting seals designed to maintain moisture out. As soon as inside, saltwater can create brief circuits between the battery’s terminals, resulting in overheating and doubtlessly inflicting a harmful phenomenon known as thermal runaway.
In easy phrases, thermal runaway is when warmth from a brief circuit spreads via the battery cells, leading to an uncontrollable chain response. Within the case of saltwater publicity, even after floodwaters recede, the salt residue left behind can proceed to pose a danger, making it important for EV homeowners to have their automobiles inspected in the event that they’ve been submerged.
Actual-Life Examples of EV Fires After Hurricanes
The specter of saltwater-induced fires in EVs grew to become significantly obvious throughout and after main storms in recent times. Following Hurricane Ian in 2022, which ravaged components of Florida, as much as 5,000 electrical automobiles have been compromised, with 36 confirmed fires. Comparable incidents occurred after Hurricane Idalia, prompting additional concern and investigations by each automakers and federal security companies.
It’s necessary to notice that this danger appears to be particularly linked to saltwater flooding, not freshwater. For instance, no important points have been reported in California after heavy rainfall and freshwater flooding earlier this yr. Saltwater’s distinctive skill to conduct electrical energy seems to be the driving issue behind these fireplace dangers.
What EV House owners Ought to Do Earlier than and After a Storm
1. Transfer Your Car to Greater Floor
One of the best ways to stop potential battery injury is to keep away from floodwaters altogether. Florida Governor Ron DeSantis, together with security officers, has burdened the significance of relocating EVs to areas much less prone to flood. Parking your automobile on elevated floor can considerably scale back the chance of it being submerged in saltwater.
2. Preserve Your EV Charged Earlier than Energy Outages
Similar to standard automotive homeowners are suggested to maintain their gasoline tanks full earlier than a storm, EV homeowners ought to guarantee their automobiles are absolutely charged forward of potential energy outages. Whereas charging choices could also be restricted throughout and after a hurricane, this easy step can present flexibility in case you want to evacuate or journey.
3. Submit-Flood Security Measures
In case your EV does turn out to be submerged in water, security doesn’t finish as soon as the floodwaters recede. Tesla and different automakers suggest towing your automobile not less than 50 toes away from any buildings or flammable objects till a licensed mechanic can examine it. This precaution is important as a result of fires can happen lengthy after the automobile dries out, as salt residue could linger within the battery.
How Doubtless Are EV Fires?
Though cases of EV fires attributable to saltwater flooding are uncommon, they occur steadily sufficient for security officers to take discover. Since Hurricane Sandy in 2012, the Nationwide Freeway Visitors Security Administration (NHTSA) has been finding out the phenomenon, however precise statistics stay onerous to come back by. Nonetheless, with extra EVs on the highway immediately, the variety of circumstances is anticipated to develop, particularly in coastal areas liable to hurricanes and saltwater flooding.
What the Future Holds for EV Security
As electrical automobiles proceed to realize recognition, the automotive business is working to handle security considerations, together with these associated to flooding and battery integrity. The NHTSA is presently exploring updates to battery security rules geared toward decreasing dangers, significantly in high-risk flood zones. Moreover, carmakers have designed their battery packs with insulation and obstacles to reduce moisture infiltration, although no system is foolproof, particularly in excessive circumstances like hurricanes.
