As electric vehicles become more common on the road, it’s important to understand how to keep EVs – and their drivers – safe during and after a hurricane or other major storm.
Before the Storm
First, if a storm is on the way, be sure to charge to full capacity. Any post-storm power outages will most likely limit your ability to charge, which could also limit your ability to evacuate or get supplies. Once your EV is fully charged, unplug it before the storm to avoid any potential power surge.
If possible, and especially if you live in a flood prone area, consider moving your vehicle to higher ground to help prevent water damage.
After the Storm
If your EV has been flooded, it’s important to have it checked out by a qualified technician before getting back on the road. The technician should test the EV’s battery, electrical systems and charging system. Also, be sure to check for moisture to see if water has made its way into spots not easily visible. If so, your EV may have to be towed to the technician.
Finally, when you’re safe and ready to get back on the road, keep your fellow EV drivers in mind. Wherever you charge up post-storm, be sure to move your vehicle from the charging station immediately after you’re fully charged to give others access.
What to Do If Your EV Is Flooded
The major danger to an EV during a hurricane or other serious storm is flooding, which could lead to water intrusion in the battery. Although EV batteries are typically sealed and water-resistant, water can still get in. This is more probable if your EV has been in a fender bender, which can compromise the battery seals.
While an EV doesn’t electrify the water around it, a flooded vehicle introduces some serious safety concerns and potential fire risks, especially if it’s submerged in salt water. Regardless, submersion in any type of water for an extended period puts your vehicle at risk of damage.
Water damage to the battery can cause “thermal runaway,” which can lead to the battery overheating and catching fire. To prevent this, keep an eye out for leaking fluids and strange smells.
If you notice any of these signs, unplug the vehicle from the charger, move away and call your authorized EV dealer to arrange a thorough inspection. This fire risk is rare, but it is possible.
While EVs are designed with advanced safety features, including those offering water protection, proper precautions are still necessary during extreme weather conditions. Please keep these guidelines in mind in time of a hurricane or other serious storm and drive safe.
