A powerful hurricane can cause catastrophic damage in a few short moments. Damage to lithium-ion batteries can generate high amounts of heat, and fires that are difficult to extinguish. Hurricanes and electric vehicle battery fires are just one of the challenges first responders face. What precautions should EV owners take?
Impact of Hurricanes on Electric Vehicle Batteries
A major hurricane blowing onshore, can cause a storm surge ten feet high with a following wind. The salty sea water will be highly corrosive. Prolonged submersion can cause a short circuit, leading to an electric battery fire depending on the chemistry.
“Anything with those lithium-ion batteries needs to be moved out of surge zones”, an emergency manager advised Washington Post. The same applies to electric-powered bikes, mobility scooters, wheelchairs, and golf carts too.
What EV Owners Can Do Before a Hurricane Arrives
Albert Gore is executive director of the Zero Emission Transportation Association (ZETA). His organization issued a brochure (see link below) to help consumers cope with hurricanes and electric vehicle battery short circuits. The online document recommends the following proactive steps:
- Move an electric vehicle away from the path of the storm. If you are evacuating take the vehicle with you.
- If you cannot do either of the above, then park the electric vehicle on high ground away from other fire risks.
- Do not leave your EV plugged in during severe storms, because this may increase the risk of short circuit and fire.
What To Do If a Hurricane Floods Your Electric Vehicle
Saltwater is corrosive and can damage a battery pack, whereas fresh water and heavy rain are unlikely to do so. All electric vehicle batteries have built-in protection against flooding.
Despite this, ZETA recommends filing an insurance claim if you have electric vehicle water damage, and towing it to an authorised service center for a safety inspection. Your insurance company will expect you to act responsibly, and to avoid further damage where this is possible.
