If an EV’s traction battery catches fire, the driver’s job is short: get everyone out of the car, move well away from it, and call the emergency services. Do not try to fight a battery fire yourself, do not open anything, and do not go back for belongings. A burning traction battery is a fire-service job, full stop.
Key Takeaways
- Smoke, hissing, chemical smell or battery warnings mean: out, away, and call the emergency services.
- Never fight a traction-battery fire yourself, touch the orange cables, or unplug a burning car.
- Tell responders it is an electric car with a battery involved — it changes their response.
- A damaged pack can flare again; afterwards the car goes by flatbed to professionals, never into a garage.
The Signs That a Battery Fire May Be Starting
A battery fire usually announces itself before flames appear:
- Smoke or vapour from under the car, not from the brakes or tyres.
- Hissing, popping or crackling sounds from the pack area.
- A sharp new chemical smell.
- Warnings on the dashboard about the battery, especially alongside any of the above.
Keep the distinction clear: scorching at an outlet, a tripped breaker or a charger fault light are charger-side events with their own responses, covered in our guide to whether home EV chargers are safe. Smoke, noise or smell from the car itself is the battery scenario — the one this page is about.
What to Do, in Order
- If you are driving: pull over somewhere open, away from buildings and other cars, and get out.
- Everyone out. Take the key and nothing else.
- Move well away — the length of the street, not the next parking space — and stay upwind of any smoke.
- Call the emergency services and say clearly that it is an electric car with the battery involved. That one fact changes how they respond.
- Stay back and wait. Warn others to keep away. If the car is in a garage or car park, do not re-enter the building; let the fire service decide when it is safe.
What Not to Do
| Do not | Why |
|---|---|
| Try a home extinguisher or a garden hose on a battery fire | A pack burns inside a sealed case; a small extinguisher cannot cool it, and standing close puts you in the smoke and heat. |
| Touch the orange high-voltage cables or open the pack | The traction system is sealed, high-voltage and specialist-only — in a fire above all. |
| Unplug a charging cable from a smoking or burning car | Your place is away from the car. Responders will deal with the connection. |
| Drive the car “just to the dealer” after smoke or warnings | A pack that has vented or warned once can worsen without notice. Flatbed recovery is the route. |
| Park it in a garage after the fire looks out | Battery fires can flare again later. Follow the fire service’s instructions on where the car goes. |
After the Event
Once the fire service releases the car, the path runs through professionals: flatbed recovery to a dealer or the manufacturer’s facility, and an insurer’s assessment. Do not charge, jump-start or drive it in the meantime — a burned pack is not repaired at the roadside, and the 12-volt jump pack in the boot is irrelevant to it.
The Proportionate View: Prevention Is Installation and Equipment
Battery fires sit at the rare, severe end of a spectrum whose everyday end is mundane: correct installation to code, certified equipment, and attention to warnings. That is the side a charger maker works on. EVDANCE home chargers such as the EV-ACT5006T 48A Level 2 wall charger (ETL/FCC/CE) and the EV-ACS4005T 40A NACS portable charger (IP66) are built and certified for daily charging duty, with a 3-year standard warranty. Our portable EV charger safety guide covers the installation side in full.
Frequently Asked Questions
Can I put out an EV battery fire with a fire extinguisher?
No. A small extinguisher cannot reach or cool a fire inside a sealed traction pack, and trying keeps you close to smoke, heat and venting gases. Get away and call the fire service — extinguishing a battery fire is their work, with their equipment.
Can an EV battery fire start again after it looks out?
Yes, a damaged pack can flare up again hours later, which is why responders monitor the car and direct where it is taken. Follow their instructions: do not garage the car, and do not try to charge or move it yourself.
What if the smoke is only at the wall outlet or charger, not the car?
That is a different event: a charger-side fault. If nothing points to the car itself and you can reach the circuit breaker without passing the car, switching the circuit off is the first step in our safety guidance. If anything points to the car — or you are in any doubt — treat it as the battery scenario: out, away, and call.
