Not Just for Cars: Lithium-Ion Fire Blankets for E-Bikes, Garages and Workshops
Most of the headlines are about electric cars, but a lot of lithium-ion fires start much smaller: an e-bike charging in the hallway, a scooter in the garage, a box of power tool batteries on a workshop shelf. The same thermal runaway that makes EV fires hard to fight happens in these batteries too, just in a smaller package that’s often sitting inside your home.
Sized for the job
Fire blanket makers now build products specifically for these risks. Fire Isolator’s lithium-ion battery blankets are aimed at equipment, tools, battery storage systems, e-bikes, and e-scooters, and they’re rated for peak temperatures up to 1,600°C and sustained temperatures of 1,200°C for extended periods. Larger ones can cover a lot. Vigil’s 4m x 3m blanket is sized for solar storage batteries and forklifts, and will also cover an electric motorbike, e-bike, mobility scooter, drones, and power tools.
What the research says about small-scale fires
A 2026 study published in the journal Fire tested blankets on e-bike and battery fires. The researchers found that the blanket blocked splashing batteries and jet flames, reduced combustion intensity, and gave personnel a safe way to operate portable fire extinguishers. That last part matters. Battery fires can literally throw burning cells, and a blanket puts a barrier between you and that debris.
Here’s a look at how blankets are being used in automotive workshops, where EVs and loose battery packs are now everyday business:
Blanket plus extinguisher
At home, think of a blanket as your containment tool, not your only tool. It helps smother surface flames and keep the fire from spreading to walls, furniture, and other items, which is crucial in a home or hallway. Pair it with an extinguisher rated for battery fires and a plan for getting everyone out.
A few habits that make a real difference:
- Know the warning signs. If an e-bike battery starts venting, hissing, swelling, or producing white smoke, get it outside immediately if you safely can.
- Expect reignition. A damaged battery can reignite, so treat the area as hazardous until firefighters confirm it’s safe.
- Practice before you need it. Unfold your blanket once so you know how it handles.
- Call the fire department. A contained battery fire is still a battery fire.
For fleets and workshops
If you run a shop, a delivery fleet, or a rental operation, it makes sense to stock blankets in two sizes: a vehicle-scale blanket for cars and vans, and smaller ones positioned near charging stations and battery storage. This demonstration from Japan shows a reusable car blanket being put through its paces with a fire academy:
Lithium-ion batteries aren’t going anywhere. Having the right blanket within reach turns a scary moment into a controlled one, and that’s a pretty good trade for something that folds into a bag on the wall.
