Electric vehicle battery fires—what to know and how to react

Lithium-ion battery fires can be intense and frightening. As someone who used to repair second-hand smartphones, I’ve extinguished my fair share of flaming iPhones with punctured lithium-ion batteries. And the type of smartphone battery in your pocket right now is similar to what’s inside of electric vehicles. Except, the EV battery stores way more energy—so much energy that some firefighters are receiving special training to extinguish the extra-intense EV flames that are emitted by burning EV batteries after road accidents.

If you’ve been reading the news about EVs, you’ve likely encountered plenty of scary articles about battery fires on the rise. Recently, the US National Transportation Safety Board and the California Highway Patrol announced they are investigating a Tesla semi truck fire that ignited after the vehicle struck a tree. The lithium-ion battery burned for around four hours.
