You beat me to it - Googled and found it's 350W or 750W, both sold derestricted:

You can see that the burnt one has a much taller battery and bigger motor. There's also a large controller fixed underneath the rack.

Interestingly handlebars are scorched while Deliveroo bag survived quite well. Maybe they make them fireproof now having so many of their bikes catching fires.

Maybe they did a risk assessment on their 'riders' and decided fireproof bags were needed to stop the pizzas and curries overcooking. Customers would not be happy to get a frizzled curry.

One good thing about that report is that its seems relativly clear what happened.

 

A conversion on a eBike with a much larger (illegal ?) motor fitted and the fire happened the day after a 'new' charger was used.

They bought a new charger because they had replaced the original battery with a bigger one. presumably, the charger was a fast one because the bigger battery would take too long to charge with the old one.

I am just amazed that so many people don't know basic Physics and chemistry when it comes to batteries, you still hear idiots throw water on fat fires or charge bikes AT NIGHT, ok die in your sleep, at least you will be unaware.

 

Also amazing is that people even now don't have smoke alarms, REALLY :mad::mad::mad::mad::mad::mad:

 

Oh and STOP BUYING CHEAP CHINESE LOW QUALITY BIKES with cheap batteries

The advice given by the fire service.

 

Quote...

"A Fire England advice page also details battery warning signs to look out for, including battery overheating, deformation, odd noises or smells (including smoke) and the battery not charging as normal."

 

So what does one do if the battery is deformed or bulging a part from not using it or charging it, the recycle system wouldn't take it. Noises, smells & smoking possibly ring the fire service???

Dig a hole in the garden, drop it in and cover it with soil. It will sort itself out eventually.

 

If you haven't got a garden, put it in the oven, that doesn't mind getting very hot for a while. ;)

Threw mine away decades ago, and the hallways in our flats had them taken out. Same reason:

 

Useless things, get a bit cold and the low PP3 battery beeps in the night drive everyone mad.

.

Dumb comment, I am a single father of three autistic sons, OURS went off years back, saw nothing, walked up the hall, nothing, FIRE in the annex

beeps in the night drive everyone mad.

 

It always happens at night. I am sure those bloody things have inbuild timers with one purpose only: to annoy me.

 

But I am glad to hear it happens to you too. It feels little better now when I know I am not personally targeted. :)

Dig a hole in the garden

Done that with a few old mobiles, so defo food for thought, let the Fire service give advice but not aid in practical solutions.

I doubt the fire service will like this practical and perfectly reasonable solution: If I get the dead escooter I found a few months ago working, I could put it upside down with it's wheels pointed up on my windowsill with the window open when charging my ebike battery, power the escooter with a 24V power supply, make a box to sit on top of the wheels to hold the flaming battery, to be safely flung out of my home automatically by the throtte when activated at say 90℃ by a temperature controlled switch. It's the only good use for a escooter I can think of.

I feel that my neighbour may not appreciate that idea when her cars goes up with it, but yes I have similar plan, excluding the scooter! Mine involves a small shovel and an oven glove :p

By law you have to put warning signs in entire neighborhood:

 

"Danger! Insane ebike owners!"

The advantage of getting a machine to do the flinging is, it can be done remotely - you don't want cells exploding like grenades in your face while you attempt to shovel the flaming and disintegrating battery outside like this poor guy in the video below - I bet he wishes he'd had a Flaming Ebike Fire Flinger! His kids wouldn't need pills to deal with the trauma of surviving the experience and his family would still have a house to live in. I also bet he'd have preferred his neighbours car burned to a crisp instead of his family's home and belongings. It's all very well saying we must be awake while charging, but there's got to be a better plan than to charge while awake so we can run for our lives to watch our homes and belongings burn from a safe distance, should the very extremely unlikely ever happen. Fling the damn fire out!

My power supply is only 2A - so unless I add wings, propeller and radio control, I expect about 1ft flinging distance... which would be far enough for the boxed flaming battery to fall into a water butt under the window. Or into a pre-dug hole to be covered by an automated soil flinging escooter. The lesser evil and personal inconvenience and cost to myself, of setting my neighbour's car ablaze would require illegal derestriction of the escooter (might not be illegal if used in private airspace), a 300A power supply, and a second escooter to fling out the first, when it's motor bursts into flames after it's flung out the flaming battery 50ft. Still, it's good repurposing for otherwise dangerous and utterly useless escooters. I've sent blueprints to Zelensky, which might be intercepted by the Russians. It could win the war.

a battery has to get hot before it bursts into flame? how fast is the heat up ? could a simple off the shelf temperature controlled socket set to power down at say 10 or 20c above ambient enclosed with the the battery during charging ward off many possible fires? and give advance warning of future battery issues?

 

Inkbird do a nice cheap range of such controllers aimed at brewers and distillers with remote sensors.

 

 

if its a case of thermal runaway? then a more sophisticated approach may be required. Perhaps monitoring the speed of temperature change rather than the actual temperature itself, with multiple sensors, continually monitored in a cycle to react if and when any accelerated heat up takes place should be fairly straight forward to knock up with an arduino or similar. determining what constitutes safe and unsafe states however could be dangerous and expensive ;)

 

But If there are any indicators prior to the point of no return a monitoring system can be built.

You like to make things complicated, don't you! Why not use my method. It's much simpler and it gives you the chance to make an opportunity from a crisis, so all that management training you had would be justified. You tie a short piece of cable between the dog and the battery. Charge the battery near where the dog sleeps. When the battery bursts into flames, the dog starts yelping, which wakes you up, then the dog runs out the dog flap in panic, dragging the battery with it. You remain safe and become more wealthy because you won't need to pay for any more dog food. Win, win.

Here's actual footage from my Illuminati World Orgy Management Domination Seminar - someone lit a 18650 and waved it around mumbling stuff, then I was ordered to strip:

I've been pricing up a fire suppression installation for my front room.

 

It'd be cheaper to make a steel box to charge your battery in, by bolting together 5mm thick steel sheet, to bolt to a large long handled spade, with the open end forward to prevent flaming blasts to your face and body. Forward thrust from the explosions and jets of flame could fully open the window you've left slightly ajar. Fling the flaming battery out at something cheaper to replace than your house and belongings.
