Electric vehicle high voltage battery pack fire basics for emergency responders

- What's inside an EV battery pack & why do they catch fire?
An EV is powered by lithium ion battery cells; multiple cells make a battery module, & multiple modules make a battery pack. The pack sits underneath the vehicle, between the wheels.
If a battery cell is abused, it can short circuit & heat up, going into what's known as thermal runaway. Heat is dissipated into surrounding cells & eventually the pressure becomes too much & those cells burst, venting large clouds of toxic & flammable gases which may then ignite or, in a small number of incidents we researched, explode.
If you're an emergency responder, get ahead of electric vehicle technology by familiarising yourself with how battery packs are constructed, why they catch fire & what the signs of thermal runaway are with this short video.

About the EV FireSafe research project
EV FireSafe is a research project aiming to identify the risks to emergency responders when attending an electric vehicle (EV) lithium traction battery fire, particularly where that vehicle is connected to energised charging. Our all-female team are proudly funded by the Australian Department of Defence, with assistance from Deakin University.

Great video thanks Emma. Do you have any thoughts as to whether salt water would be good/bad to use to suppress a thermal runaway if it was easier to access than fresh water?
If we are fortunate enough to have an unlimited water supply, how long will the application be necessary? What is the recommended flow rate and how toxic is the run-off and smoke?
Hi Shan, great questions.
Application of water will differ depending on a number of factors; number of cells in thermal runaway, state of charge of battery at time of incident etc. I'd say you can comfortably expect a 3-4 hour timeframe based on research case studies.
Don't know about flow rate, will have a look at get back to you.
There's very little testing on water run off, but what we do have indicates no more toxic than with an ICE vehicle. Usual SOPs apply; be mindful of nearby natural waterways etc.
Smoke from lithium ion battery is very toxic, containing HF amongst other gases. Due to length of firefight you'll typically need more BA operators than usual; maybe up to 12 cylinders. Smoke from vehicle plastics same as ICE vehicles.
Thanks for watching & please keep the questions coming!

'Lots of water required to put it out' she says.........To qualify that statement, according to research by American Fire Agencies.& their recent video, an ICE vehicle will need approximately 1400 litres of water to put the fire out,..............HOWEVER, an ev vehicle fire WILL NEED UPWARDS OF 30,000 LITRES OF WATER !!!! as the local fire chief said "we are simply no where near that amount of water all the time" !!!!!!!
If you charge the ev at home overnight to use cheaper electricity & a fire starts........their is more than a fair chance the home will also burn down....as per various videos on RUclips recently.
Its not ME making up these stories,....the videos prove its going on Worldwide.
It's a traction motor, powered by a battery. Jesus you can't even get the most basic stuff right.
One more reason that ev is not environmental friendly
You just convinced me never to buy an ev
EV Semi Truck Warning - 82,000 pounds? That will DESTROY highway roads. Secondly. So you want a 35,000 pound lith-ion fire also on the highway? Fun facts. The 4,000 pounds EV car batteries take anywhere from 3,000 gallons of water to 16,000 gallons of water to put out fire. Each fire engine contains 1,000 gallons on average. Hence, this truck bomb would require 16 fully loaded fire engines to be available on site. That wont be possible, so they will be burning to the ground on the highway. Third. The class D fire will be creating cubic tons of pollution in both the air and ground including HYDROFLOURIC ACID!!! There is nothing GREEN about satans agenda to burn everyone alive including animals. Over 100,000 people have already been burned alive in electric vehicle fires. Wake up, liars have run amuck in this realm with their endless male cow poop. - Neo
how do you NOT understand how battery's work? (thermal runway is NOT a chemical reaction, its in it name THERMAL) and your chemistry is wrong!
Yeah, we're pretty sure we know what we're doing. But if you have a constructive comment rather than mildly abusive ranting, we're happy to discuss.
You obviously have no idea 1littlelee.
