The dendrites (post #334) happen in a full sized EV battery. Can't say how the power tool batteries are designed or ebike batteries.Correct me if I’m wrong, but the voltage and external charger are more like a power tool in protocol than an auto battery. So unless all these anti EV people are also anti all lithium battery power tools and they refuse to have them around as well, it belongs in a discussion of power tool safety not EV s.
Generally speaking, there can be little difference between the battery packs for a car than for a tool. The cells can be similar. What’s different is how many cells and how they are configured in a pack to give the desired voltage and CapacityThe dendrites (post #334) happen in a full sized EV battery.

The charger in the OP's fire may have been the correct one, but an amperage over the ebike battery recommendations is risky. No details are given in the OP, though a cheap Chinese charger will go bad and a replacement will be found maybe not compatible with the battery.
Sure, repeat it three times and click your heels together.
The cells in a battery pack of the future may be able to be monitored individually by a robot, which would decrease repair time and costs. Manufacturers should be held to some kind of design standard for cells and groups of cells. If a bot is dealing with a full warehouse at the vending station, it should be able to quickly spot a dangerous situation, made less so by lack of oxygen.Generally speaking, there can be little difference between the battery packs for a car than for a tool.

Dendrite formation is the first step in thermal runaway, post #334 says: 'It is well known that dendrite can be easily formed if the battery is charged i) at high current densities....ii) under overcharging conditions when graphite is overlithiated, iii) at low temperatures (for example, ~0 deg. C) due to increased viscosity of the liquid electrolyte and increased Li-ion diffusion resistance.'
The last item is why we will wrap the trike battery in a heating pad for subzero operation.
So, considering there are 50X the number of ICE cars on the road and their fires are only 11X that of EVs actually makes them 5X safer and 5X less likely to start a fire!Still, NONE is prone to fire at any rate approaching gasoline fires which are 11 times the EV rate.
And gasoline fires are easy to put out compared to EV fires which once started, are nearly impossible to stop almost certain to consume the entire car, all the vehicles in the area around it, and even burn down your whole home.Care to guess how many fires occur during charging

have you ever tried to put out a gasoline fire while your in the car ? Hilarious. Want to compare the death rates between the two ?And gasoline fires are easy to put out compared to EV fires which once started, are nearly impossible to stop almost certain to consume the entire car, all the vehicles in the area around it, and even burn down your whole home.
Made up shit…you have your numbers ass backwards Mr EE…did you take any math ?So, aside from establishing that ICE cars are 5X less likely to start a fire, but when an EV does catch fire, each fire is far more dangerous, damaging and worse!
Where does the word "rate" (not even mentioned in my post above) figure into electrical theory? Is that anything like a j-operator, time constant, or phase angle?You’re an EE and you don’t know what the word Rate means?
You don't know? You sure seem to have a lot of opinions about something you know nothing about. I bet you also know a lot about SS7, common channel signaling, token ring, OC48, DS1, T1 rates and stuff like that too.Hilarious. BTW, what does EE stand for ?
I'd be happy to supply you with an algebra problem so we can see if you can even work it out.You don’t compare rates linearly lie you’re doing bubba. Gessus, you’re no EE what ever that means, you don’t know math ?
No, that was me laughing at you, talking pure gibberish again.You laughing at yourself for being so stupid ?
Never have had a gasoline fire to deal with in 50 years of driving. I bet a lot of EV owners wish they could say that.have you ever tried to put out a gasoline fire while your in the car ?
It woulds be pointless as you've demonstrated your inability to adjust for the fact that you are comparing two things, one 98% of the market while the other a mere 2%, yet you try to relate them directly. But then, you think comparing rates of automobile fires somehow equates to electrical and electronic engineering.Hilarious. Want to compare the death rates between the two ?
Story of your life.Made up shit…
Hilarious. A rate is determined by the ratio of two known quantities, not to other rates that are determined by different quantities. You just failed your algebra test…Where does the word "rate" (not even mentioned in my post above) figure into electrical theory? Is that anything like a j-operator, time constant, or phase angle?

Hilarious. I’ve already shown I can do HS math. Why should I embarrass you any more.I'd be happy to supply you with an algebra problem so we can see if you can even work it out.
Why, because you fked up trying to incorrectly compare two ratios ? What a math illiterate you are.No, that was me laughing at you, talking pure gibberish again.
That’s because fires in ICE cars happen so infrequently….and depending how old the cars are that you drive, an EV is up to 100 times less likely than that. Now that is the correct way to compare ratios. And you can now see how ridiculous it is to pretend….what ever shit that Is.Never have had a gasoline fire to deal with in 50 years of driving. I bet a lot of EV owners wish they could say that.
That’s why we use the word RATE. Then you use two of the SAME comparable qualities in each different category and compare the rates. THATS HOW YOU COMPARE RATES Mr EE, not your made up shit. Give it up…you’re wrong.,It woulds be pointless as you've demonstrated your inability to adjust for the fact that you are comparing two things, one 98% of the market while the other a mere 2%, yet you try to relate them directly.

Too funny. You think a ratio is algebra???Hilarious. A rate is determined by the ratio of two known quantities, not to other rates that are determined by different quantities. You just failed your algebra test…
A ratio, especially one expressed with a vinculum is actually more akin to an arithmetical operation.Because it would expose you as a lying jackass.I’ve already shown I can do HS math. Why should I embarrass you any more.
You said it. Thanks for again making an ass of yourself.That’s because fires in ICE cars happen so infrequently….
More baseless unsupported bullshit?an EV is up to 100 times less likely than that.
Now WHAT is the correct way? You assign success to things you haven't even accomplished. Are you just a total idiot or a deliberate idiot liar?Now that is the correct way to compare ratios.
What, those telecom terms I offered? You don't know the T1 rate is based on VB of the human voice? Very basic stuff.And you can now see how ridiculous it is to pretend….what ever shit that Is.
We? You and your dog?That’s why we use the word RATE.
What are you besides a door greeter at Walmart? Anything?THATS HOW YOU COMPARE RATES Mr EE, not your made up shit. Give it up…you’re wrong.,
Thanks for this info. We'd like to see the stats for Li-charging fires, anywhere.This is why you’ll never duplicated the charge capabilities of an automobile with an ebike or power tool Charger.
A built in charger in an EV prepares or conditions the battery for a charge by warming or cooling the battery to its ideal charging temps. It also keeps it in its ideal operation range.
This isn’t particular to lithium batteries, as some other battery types are subject to this condition.
NiMH batteries used by Toyota in northern climates are safer but have less density. Solid state batteries are also in the horizon within months.
Still, NONE is prone to fire at any rate approaching gasoline fires which are 11 times the EV rate. The yearly average for gasoline fires just at filling stations alone is over 4000 per year. Care to guess how many fires occur during charging at fast charge stations where batteries are most vulnerable ?
Lets see, one in the Netherlands in 2021, one in Germany in 2020…..At we close to 4000 in one year yet ?
Regardless, over 4000 gasoline fires happen every year at gas stations. We’ve come to expect it. Somehow, all we see in the news is the very infrequent EV fire.Thanks for this info. We'd like to see the stats for Li-charging fires, anywhere.
Extrapolating speculations to a vending scenario, say in the Netherlands, a flood-proof (underground?) battery warehouse would already have the steel structure of the building to adapt to fire- and explosion-proof compartmentalization. A fire or explosion would only "kill" a robot. The robots would operate swiftly to exchange one battery for another. Why not?

'If Kafka is the greatest theorist of bureaucracy, it is because he shows how, at a certain level (but which one? it is not localizable), the barriers between offices cease to be a "definite dividing line" and are immersed in a molecular medium (milieu) that dissolves them and simultaneously makes the office manager proliferate into microfigures impossible to recognize or identify, discernible only when they are centralizable: another regime, coexistent with the separation (and [italics]) totalization of the rigid segments. (10.) We would even say that fascism implies a molecular regime that is distinct both from molar segments and their centralization.
Doubtless, fascism invented the concept of the totalitarian State, but there is no reason to define fascism by a concept of its own devising....
