The truth about Saltwater and EV Fires

Admin

Updated: Nov 11, 2024





The recent discourse surrounding electric vehicles (EVs) and their safety has been amplified by reports suggesting that exposure to saltwater, particularly in hurricane-prone areas like Florida, could lead to these vehicles catching fire. The conversation has been fraught with sensationalism, often overshadowing the nuanced realities of EV technology and safety.


While it is essential to consider the potential risks, it is equally vital to ground this  discussions in facts and data. Take Hurricane Ian, for example—a Category 5 storm that submerged approximately 3,000 electric vehicles in saltwater. There was  extensive exposure, there were 17 reported fires attributed to these vehicles. This statistic yields a fire risk of just 0.567%, a figure that may surprise many who assume that ANY EV submerged in saltwater will catch fire. Some media reports suggested this was a very low number but completely ignored the fact that if 3000 ICE (internal combustion engine) vehicles were submerged, ALMOST NONE OF THEM WOULD HAVE CAUGHT FIRE! So why are some in  the media suggesting this is no big deal?

 

It's crucial to understand the broader implications of this data. While the probability of an EV catching fire due to saltwater exposure is low, the corrosive and conductive nature of saltwater can damage electrical systems in all types of vehicles, including internal combustion engine  cars. This damage could potentially lead to electrical failures  in either category of vehicle. The difference is that ICE vehicles would not burn in a flood, while an EV may catch fire and burn out of control as battery fires are much more difficult to put out.

 

Understanding the likelihood of an EV being submerged in saltwater is essential for contextualizing these statistics. While certain coastal and flood-prone regions may see more incidents of flooding, the everyday risk for the average EV driver remains relatively low. It is critical to recognize that while severe weather events like hurricanes can lead to hazardous conditions, the average driving experience does not typically involve such extreme scenarios. The perception that electric vehicles are inherently dangerous, as some critics have suggested, is questionable.


The automotive industry has made significant strides in improving the safety and reliability of EVs, and as data from reputable studies shows, the chances of an electric vehicle catching fire under normal circumstances are minimal. The emphasis on safety has led to enhanced battery management systems and improved fire safety measures in newer electric vehicle models. Still the possibility of fire exists in both kinds of vehicles.

 

Moreover, ongoing advancements in battery technology are set to further mitigate risks associated with EVs. Manufacturers are increasingly adopting materials and designs that improve thermal stability, reducing the likelihood of fires resulting from various conditions, including flooding. As the market continues to evolve, these innovations will contribute to the overall safety of electric vehicles.

 

In conclusion, while the media has exposed the risk of electric vehicles catching fire due to saltwater exposure, the data reflects a more balanced perspective. The actual risk remains low, particularly when considering the vast number of vehicles that experience similar conditions without incident. By focusing on facts rather than fear, we can foster a more informed dialogue surrounding electric vehicle safety. As we continue to explore the future of transportation, it’s essential to advocate for a balanced view, recognizing both the challenges and the incredible potential of electric vehicles.
