Hurricane Helene Threatens EVs: Owners Warned of Saltwater Fire Risks
Electric Vehicle Owners Urged to Take Precautions as Hurricane Helene Approaches
As Hurricane Helene bears down on coastal regions, electric vehicle (EV) owners are being advised to take special precautions due to the unique risks posed by saltwater flooding. Recent incidents have highlighted the potential for EVs to catch fire if submerged in saltwater, prompting officials to issue warnings and safety guidelines.
Florida Governor Ron DeSantis has urged EV owners to move their vehicles to higher ground ahead of the storm. This advice comes in response to the increased fire risk when electric vehicles are exposed to standing water, particularly saltwater. Tesla, a leading EV manufacturer, has also released guidance, emphasizing the importance of avoiding submersion and recommending that submerged vehicles be towed away from structures.
Power outages present another challenge for EV owners during severe weather events. Experts recommend keeping EVs fully charged to maintain flexibility during potential blackouts. However, it’s worth noting that conventional vehicles face similar challenges, as gas stations are unable to pump fuel without electricity.
The National Highway Traffic Safety Administration (NHTSA) has been researching EV fires following flooding events since Hurricane Sandy in 2012. Recent incidents during Hurricanes Ian and Idalia have renewed concerns about potential fires as Hurricane Helene approaches, particularly due to the expected storm surge.
Tom Barth from the National Transportation Safety Board (NTSB) explains that saltwater’s ability to conduct electricity can lead to short circuits in lithium-ion batteries, potentially causing thermal runaway and fires. While carmakers have implemented design measures to prevent battery short circuits and moisture intrusion, the risks associated with submerged batteries remain significant.
The NHTSA continues to work on improving battery safety and updating safety requirements for electric vehicles. Ongoing research is crucial to understanding and mitigating these risks as the adoption of electric vehicles continues to grow.
As Hurricane Helene approaches, EV owners are advised to stay informed about local weather conditions and follow official guidance to ensure their safety and the safety of their vehicles.
