The Dangers of Flooded Electric Vehicles
In the aftermath of Hurricane Helene, authorities are warning electric vehicle (EV) owners about the potential risks of driving flooded cars. Flooded electric car batteries that have been submerged in salt water can pose a fire risk due to the possibility of triggering a short circuit. It is essential for the safety of both the vehicle and the occupants to never attempt to drive any vehicle that has been flooded without first having it inspected by a technician. With the recent devastation caused by flooding in the Southeast, particularly North Carolina, it is crucial for EV owners to heed this warning to prevent any potential hazards.
Tesla’s Recommendations for Flooded Cars
Tesla, a leader in the electric vehicle industry, has long warned about the fire risks associated with flooded cars. The company advises against driving a car that has been submerged until it has been inspected by an authorized repair facility. It is also recommended to park flooded vehicles at least 50 feet away from any structure to minimize potential fire risks. Florida Governor Ron DeSantis has urged EV owners to take precautions and move their vehicles to higher ground ahead of any potential flooding. The National Transportation Safety Board has also highlighted the dangers of saltwater short-circuiting batteries, emphasizing the importance of prompt inspection and maintenance for flooded electric cars.
Research on Fire Risks in Flooded EVs
Research conducted by the National Highway Traffic Safety Administration (NHTSA) following Hurricane Ian, which flooded thousands of electric vehicles, found that a small percentage of flooded EVs posed fire risks. While only 6% of the vehicles were declared total losses, about 6% of those totaled cars ignited. The Idaho National Laboratory conducted further studies on various EV models, including Lucid Air, Porsche Taycan, and Tesla vehicles, to assess potential fire risks after submersion. It is essential for EV owners to be aware of the risks associated with flooded cars, even if they appear dry, as fires can sometimes start after the floodwater recedes.
Safety Precautions for Flooded EV Owners
In light of the potential fire risks posed by flooded electric vehicles, it is crucial for owners to prioritize safety and take necessary precautions. Attempting to turn on a flooded car may cause further damage, even if there is no immediate fire risk. If floodwaters have reached past the floorboards of the vehicle, it is likely considered a total loss, regardless of the powertrain type. Authorities recommend moving submerged EVs to safer locations, especially if they are inside attached garages, to minimize the risk of fires. Emergency services may be limited during natural disasters, making it essential for owners to stay vigilant and prioritize safety.
Continuous Improvement in EV Safety
As electric vehicles continue to evolve, automakers are working diligently to enhance safety features and ensure that EVs fail safely in extreme circumstances, such as flooding. Authorities, automakers, and regulators are constantly learning more about handling EV-related fires and addressing specific issues. Despite the rare occurrence of EV fires compared to internal combustion engine fires, it is essential for EV owners to take proactive measures to prevent any potential hazards. Technologies such as Vehicle-to-Load (V2L) and Vehicle-to-Home (V2H) functions in EVs can be valuable assets during natural disasters, providing power for essential home electronics when the grid is down.
Conclusion
In conclusion, the aftermath of disasters like Hurricane Helene serves as a reminder for electric vehicle owners to prioritize safety and take necessary precautions in the event of flooding. The risks associated with submerged EV batteries are real and can pose fire hazards if not addressed promptly. By heeding the warnings from authorities and automakers, EV owners can ensure the safety of themselves, their vehicles, and their communities. As the electric vehicle industry continues to grow and evolve, ongoing research and advancements in safety measures will enhance the overall resilience of EVs in extreme circumstances. By staying informed and proactive, EV owners can mitigate risks and contribute to the continued safety and sustainability of electric transportation.
