Electric vehicles at risk during floods: Insights and precautions

As Hurricane Milton approaches, Florida authorities are advising residents to move their electric vehicles (EVs) away from areas that could be affected by flooding and storm surges. This precautionary measure is critical to avoid the risk of electric vehicles catching fire due to prolonged immersion in salt water, a scenario that, while rare, poses a significant threat.

During torrential rains in Hallandale Beach, Florida, in June, a blue sedan plugged into an electric charger was photographed with its wheels partially submerged. This incident highlights the vulnerabilities associated with electric vehicle charging in flood-prone areas. The Facebook page for Hillsborough County, which includes Tampa, stressed the importance of keeping electric vehicles and their lithium-ion batteries away from floodwaters to prevent potential fire hazards after the water recedes.

Electric vehicles, like many modern devices, rely on lithium-ion batteries for power. These batteries are also commonly found in e-bikes, scooters, wheelchairs, golf carts, as well as electric lawnmowers and cordless tools. When these batteries come into contact with salt water, chemical reactions can occur that can cause fires once the batteries dry out.

The risk associated with submerged EV batteries is not to be taken lightly. While events are rare, there is a risk of damage and danger, particularly in scenarios where vehicles remain in floodwaters for prolonged periods. The expert advice is clear: Moving electric vehicles to higher ground could prevent the twin challenges of vehicle loss and fire risk, both of which could complicate already difficult circumstances during and after a hurricane.

As Hurricane Milton approaches, residents in affected areas should prioritize safety by securing their vehicles in safe locations, paying attention to local warnings, and staying informed through trusted sources. This proactive approach not only ensures personal safety but also mitigates the risk of property damage during such natural disasters.
