An EV fire blanket is a large sheet of fire-resistant fabric, big enough to cover a whole car, that trained crews and site operators pull over a burning vehicle to contain the flames. It is professional safety equipment, not a consumer product with a single shelf price: cost depends on size, material rating and whether the maker rates it for one use or several. Fire services and larger sites keep them; most home drivers never buy one.
Key Takeaways
- An EV fire blanket contains a burning car’s flames; it does not cool the battery or put the pack out.
- There is no single price — cost follows vehicle size, material rating and the single-use or reusable rating.
- Blankets belong with fire services, car parks, workshops and ferries, not in a home driver’s boot.
- If your site needs one, buy on test documentation, store it by the bays, and train two-person deployment.
What a Fire Blanket Actually Does
The blanket works by covering. Spread over a car, the heavy fabric cuts the visible flames off from the surrounding air and holds heat, smoke and debris close to the vehicle instead of letting them spread. In an underground car park, a workshop or a ferry deck, that can be the difference between one damaged car and a building fire.
What it does not do is stop the battery reaction. A lithium battery fire is driven by heat building inside sealed cells, and a cover cannot cool them. The pack can keep reacting until it cools or burns itself out, so a blanketed car is still treated as an active fire: crews keep their distance and handle cooling and recovery as separate steps. The blanket buys containment and time — it is not an extinguisher.
Who Keeps One, and Where
| Who holds it | Typical setting | Why they have it |
|---|---|---|
| Fire and rescue services | Carried on appliances or support vehicles | Contain a fire in a sensitive spot while cooling is arranged |
| Parking operators | Underground and multi-storey car parks with charging bays | A burning car underground threatens the whole structure |
| Workshops and dealerships | Service bays handling damaged or suspect EVs | A car with a damaged battery can be covered while it waits safely |
| Ferries and vehicle transport | Car decks and transporters | Vehicles are packed tightly, with no room to move one away |
What It Cannot Do
- It cannot put the battery out. Cooling the pack ends the reaction; the blanket only contains what happens above it.
- It is not a home-driver tool. Deploying one means working around a burning car — what you should never do. Get clear and call emergency services.
- It does not remove the reignition risk. A covered car can still flare up later, so it stays monitored.
- It does not replace prevention. Certified equipment and a correctly installed circuit remain the part an owner controls, as our guide to whether home EV chargers are safe sets out.
If Your Site Is Told to Buy One
A building’s fire plan, insurer or site assessment may ask for a blanket on the premises. If so, buy it as rated safety equipment, not as a commodity:
- Size it to the largest vehicle on site, with enough overhang to seal against the ground.
- Ask for the test documentation. The maker should state the material, its temperature rating and the standard it was tested against.
- Check the use rating. Many blankets are rated for a single deployment; others allow limited reuse after inspection.
- Store it where the risk is — near the charging bays, in its marked container.
- Train the deployment. It is a two-person job from the upwind side; a real fire should not be anyone’s first attempt.
The Prevention Side You Do Control
The blanket is the last line, not the first. The first is certified, correctly installed charging equipment: the EVDANCE EV-ACT5006T 48A Level 2 wall charger carries ETL, FCC and CE marks, and our commercial charging solutions page covers site setups, while how EV charging stations work explains how a site fits together.
Frequently Asked Questions
Does a fire blanket put out an EV battery fire?
No. It contains the flames above the car, but the reaction inside the sealed pack continues until the pack cools or exhausts itself. Crews still cool and monitor afterwards.
Should I keep a fire blanket at home for my EV?
Generally, no: using one means approaching a burning vehicle. Leave, keep your distance and call emergency services; prevention sits in certified equipment and sound circuits, as the checks behind whether a NEMA 14-50 outlet is a fire hazard show.
How much does an EV fire blanket cost?
There is no single price worth quoting. Cost follows the size of vehicle it must cover, the material’s temperature rating, and whether the maker rates it for one deployment or several — a small single-use blanket and a large reusable rated one are different products.
