The problem with many small EVs is that they have minimal thermal management. So, owners go out and use the device hard, heating the batts, then they come home and immediately charge them. This can exceed battery safe temps and off it goes. Some manufacturers of smaller electric devices have worked this out. A good example is the 82V battery packs from Briggs & Stratton, used for garden tools, which have a charger that forces air through the battery pack while charging, and won't charge the batt until it is at a safe temp. But, from what I've seen of most of these scooters, boards and e-bikes, they have simple chargers that may or may not connect to a temp sensor in the pack, or just rely on the pack sensor and pack BMS, which is often pretty rudimentary, to do the thermal control. Hence, boom, occasionally. Add into that the fact that the batts and their BMS are subject to high G forces in general use, at least in things like scooters and boards where they are all unsprung weight, and it's easy to imagine fatigue faults in cells, cell links and PCBs, which would lead to excessive heating. A properly designed pack would have multiple temp sensors and would disconnect the battery from input or output in the case of any temps outside of the safe range. But, that's too expensive to implement in small, cheap EVs, hence it generally isn't done. Of course, the problem will largely go away if manufacturers shift to safer chemistries like LFP or even LTO.

I dont think its heat stress which causes the "blow up" on cells, at least not regarding to your argument "warm batteries from direct use to the charger". I have a 48V 10Ah and a 26Ah scooter, both are delivered with just a 2A charger (basic on most scooters). One needs about 5 hours, the other scooter 14 hours with a single and 7 hours with 2 chargers (2x2 = 4A). So we talk about only 0,2C charging speed in case of my small battery scooter and even below 0,1C with a single charger and still below 0,2C when "fast charging" (0,15C calculated, VERY SLOW!) on the big 1,2kWh battery. Also, just think about tool batteries... they are abused with 2-4C charging speed, thats why they need this extensive and mostly loud active cooling, anything up to 0,5C is very safe for LiIon batteries of any type, 1C is not good for them in general, but still safe. Above 1C is getting... into active cooling terretory for sure (EVs, tool batteries and their fast chargers,...)

Battery management needs to be taken to the next level to detect even the _slightest_ irregularities and physically disconnect the problem cell immediately and sound some sort of alarm to let the user know that they need to take precautions right now, like taking the scooter or whatever outside immediately. Hopefully, solid state batteries that we've been hearing about for many years will finally make their debut and squash the possibility of thermal runaway once and for all (in addition to their numerous other advantages).

@Shep VanDelay I imagine that they already use the thinnest wire necessary to carry the load while also being safe, but there must be SOME way to isolate a problem cell and disconnect while keeping the rest of the pack usable. The way most battery packs are made nowadays, unfortunately, don't lend themselves to having a single cell replaced in a feasible manner, but the pack could easily be recycled. Safety first, but after that, they need to find a way to make it economical too when there is a bad cell. Maybe a trade-in allowance on the current pack - with one or several bad cells - with a rebuilt or new replacement (if you're outside the warranty period).

It is also essential NOT to charge that battery below zero degrees centigrade. Once you have done this, it can seed a dendrite and the battery can still work for maybe 100 charges but that dendrite grows each time it is charged even if it is charged at the correct temperature. Once the dendrite cuts through the separator within the battery, it causes an internal short and thermal runaway.

A few years ago my first ebike, stored downstairs, burst into flames one evening. It was during New Years eve and I actually heard the fire begin, only I thought it was a nearby firework. It was only when the smoke alarm triggered that I investigated with powder fire extinguisher in hand. In my case it wasn't a faulty battery pack but instead faulty wiring on the hub-based motor; the motor section was on fire, but the battery pack wasn't. Apparently there was a connection that came loose over time and ultimately caused the battery to dump a massive current into the motor, enough to cause the non-metal materials to ignite. I disconnected the battery pack and kept it outside, but had no rumblings from it since the pack wasn't damaged. So the cautionary tale here is that it's not only the battery pack that can betray you and it's worth investing not only in reliably sourced equipment, i.e. not the shonky Chinesium products, but also to have them regularly serviced to try and pick up on other electrical points of failure.

Worth mentioning that LFP (lithium iron phosphate) chemistry is slowly taking over from Lithium turnary chemistry. LFP is a lot safer than the older turnary chemistries and much less likely to suffer thermal runaway especially when fully charged to 100%. This chemistry is also way better for consumer batteries as it contains no cobalt and can be cycled many more times than lithium turnary cells, up to 5,000 cycles while still maintaining over 80% capacity. This battery technology is slowly taking over from the older less safe turnary chemistries.

seemingly no mention in the video that other battery technology exists like LFP that does not pose the same thermal runaway problems LCO/NMC/NCA has. the issue is not lithium but cobalt. the cobalt allows the fire to self-sustain when battery packs fail. LFP doesnt have as good of a energy density but its not terrible either. cobalt-based Li-ion tech imo, should have more regulation. for small devices like your phone its fine, there is not much cobalt to sustain a fire, but when we start to look at EVs and LEVs there needs to be compartmentalization and precision temperature monitoring to try limit these fires, its insane we currently allow these batteries to be packed so densely when we know only one cell needs to fail for the whole pack to ignite. and if manufacturers cant come up with a good way to isolate large packs into smaller ones then they should not be allowed to use this battery chemistry.

Vehicles in London: 13956 EVs (2020) 2600000 cars total (2020) Using just total cars (excluding trucks and motorbikes), there are 186 petrol & diesel cars for every 1 EV. 186/35 = 5.3. EVs are at least 5.3 times more dangerous than gas & diesel vehicles.

There was a study on car fires done by an insurance company (autoinsuranceEZ) in the US which looked at the frequency of fires per 100,000 vehicles on the road. The findings were that hybrids had the most frequent fires at 3,474.5 per 100,000 followed by ICE at 1,529.9 per 100,000 followed by BEV at 25.1 per 100,000. Another study (this time performed by the National Fire Protection Association) examined fire frequencies per miles driven and found that between 2012-2021 there was 1 tesla fire per 210 million miles driven compared to 1 fire per 19 million miles driven for all vehicles put together.

‘A lithium ion battery is much safer than a tank of petrol’ - I have to disagree. How many times have you heard of a petrol car catching fire while parked and switched off or even while being refuelled/driven, versus all the reports of EV’s (including e-bikes and scooters) randomly catching fire in people’s homes/garages or while being charged/ridden?

More than half of fires at recycling facilities are caused by lithium ion batteries that are not properly disposed. Usually an AA or AAA battery.

Grab the nearest metal garbage can and flip it over the lithium fire!!! That is only to stop the spread of the fire... The battery produces its own oxygen is why this fire is hard to put out!!!

The ebike community should take the experience of the electric RC aircraft and heli crowd into account. Lipo batteries have a similar chemistry to Li-ion, but are more fragile,and charging and treatment of Lipos is very similar to Li-ion. First rule is don't manhandle the batteries. Second rule is don't deplete the charge. Third rule is lower charging rates are best. Even as low as 1C. Fourth rule is that hot batteries are to be left to cool. And finally, if you can, charge in a Lipo bag. But even with the above, as was seen in my RC days, the problem is mostly NOT the batteries, but the chargers and the consumption management. In the RC world that was a function of the mind and experience of the pilot. In ebike etc, it's the BMS. Don't skimp on the quality.

I unloaded a lipo drone pack 1 time to deep and then tried to charge it again. I was home at the time it was charging and heard a small hissing (no smoke yet). I didn't trust it because I know these kind of batteries can be explosive. I unplugged it and laid it outside on a dumpster... about 2 minutes later, lots of smoke and the lipo burned a whole through the lid of the dumpster. I was lucky that time! Since then I store my lipos in a lipo bag in a military ammo box (steel).

The moral of this story is that on incredibly rare occasions a quality brand name battery can malfunction or catch fire. But a cheap generic brand battery from AliExpress or the basement of Amazon will pose a disproportionately higher risk and danger. There's a reason why it was so cheap! I came to this video straight after watching an ITN news report about e-bike battery fire's. At the end of the report someone from the London fire service said that the vast majority of the fires were caused by e-bike conversion kits. He didn't specify any or the origins of the problematic kits, and I'm sure most are good quality and reputable but obviously there are a lot of cowboy manufacturers out there who could be putting dodgy quality batteries into a wide range of generic e-rides of all kinds. Buyer beware. If it's that cheap, it could end up costing you dearly 💸🔥💀⚰️

Hang on a mo..... I thought private E scooters usage was illegal in UK? That aside, a very informative video on the possible hazards of battery fires. Personally I wish these things was allowed in the UK. I suffer with my knees and walking to and from work is a pain.....literally. Under normal circumstances my journey to work would be 10 minutes and I cant justify driving to work with the added expense of parking fees. An E scooter would be the next best thing to using a mobility scooter and Im quite not ready for the Madge mobile just yet.

Note : 1. Don't wait until the battery runs out before char ging . Lithium batteries are not the same as ordinary batteries . Charging the batteries before using them is not conducive to the health of the lithium battery . Depleting the battery may cause it to fail to recharge 2. Don't put the lithium battery in a place with high temperature . The lithium battery prefers a place with a low temperature . 3. Summary of charging methods : short charging and short charging ( infrequently charging , but if you want to rush ! )

It is absolutely better to wait until the day of your next ride to charge the battery providing it is not below 50% when you store it.

these are not refrigerators or toasters!! the scooter, or bike battery should never just be left plugged in forever. As soon as it is full unplug it. and don't ride on very hot days!! I have been owning a variety of scooters and 1 Ebike without any problems. people need to read and understand the battery parameters. for example, they tell you the operating temperature and storage ranges.

Well... That's a Backfire-whatever-model... I got a skateboard from that brand. That's not comforting :P But well... From what I understand, like 99% of these battery fires happen because water got into the battery. I mean, don't ride in the rain? Don't ride on wet roads? Don't even bring it out if there's a risk of rain? I know some use these for daily commutes. Scooters in particular. Might be difficult if you got no other transportation. With that said, I use my skateboard just because it's fun. I don't use it, if the roads are even slightly damp in the morning, before the sun burns it off. Outside of summer, the roads can be wet for days after just a tiny shower of rain.
