It's almost as if lithium ion batteries are not the answer to our electrical needs
Only on the small scale. These nuclear batteries may be better.
When the salvage company was unloading the EV's that had burned on the car carrier ships, the batteries re-ignitd on the dock. The fire had been "out" for 3 weeks. They picked up the cars and put them in huge vats of water.
they burn underwater, videos on it
That's why the entire battery must be replaced even after a minor collision
We were retired downsizing from a large home, thinking of a condo. We decided against it because a neighbor could have an EV charging then burn. Most condos have not yet caught up to this problem. A rule at least to require outdoor charging. Not one place we saw has any rule yet. So we bought a smaller, single level home in a neighborhood. I am a retired firefighter and considered this issue.
Smart man
Good points to consider.
I was pulling into a parking spot at the grocery store last week just then I noticed that the car in front of me was an EV, also known as an explosive vehicle I immediately pulled out and found another parking spot. Your vehicle is not safe in a parking lot because at any time anyone could pull up next to you and park with their explosive vehicle. This really is a nightmare.
@@spy8464BB : Lucky for you your fuel won't burn!
Yet you are happy to have 100 litres of petrol sitting around? Thermal runaway with petrol is so fast is has its own name...

Great explanation. Some people are so anxious to rid us of the tried and true internal combustion engine and adopt what their short sided thinking about electric vehicles will do for the world that I believe they deliberately ignored and swept aside these very dangerous problems. From what I've seen with gasoline car fires they are relatively easy to extinguish especially it the fire fighters are called and get there quickly. I would bet there isn't much if any worry about reflash with a conventional car fire like there is with electric. I am a boat mechanic working at a marina with wet slips and dry storage. A lot of people for some reason are starting to convert from lead acid to lithium batteries. There is negligible gain compared to lead acid especially when the fire potential is considered. Also most of us in the business know the only thing most boat owners know about marine electrical theory or any other electrical theory is what some self proclaimed expert internet guru has told them. My point is with over 300 in stack storage these batteries, their installation short cuts, and poor maintenance including water intrusion is ripe for major catastrophe.
How much are garages being told to pay for their own property and public liability if they service these potential fire bombs, imagine an EV catches fire and destroys everything, even customers cars, they will have to remove all peoples cars to work on a single EV now!
People go to lithium batteries because the Lead Acid batteries don`t last. Now when you buy them you have to decide how much you want to pay for one. A cheaper one has a shorter life then a more expensive one. This is nonsense and a scam to get more money from our wallets. Btw that true trusted gas engine needs refined oil to run and we all know what that misery brings. Does Deepwater Horizon , Lac Magnantic, Exon Valdez, Kalamazoo, the burning Kuwaiti oil fields or the countless war for oil ring a bell.
Good speaker. Didn't hem haw through it, got right to the point. That's important to the students and listeners.
very informative,where I work we have a 4 story car park and they have installed charging bays on the ground floor,at an estimate I would say about 40 units and at the moment about half are used,the site management now say they will be doing the same on the first floor.. I think I shall start using the outside car park
I guess this car park management didn’t hear about the Luton Airport car park fire.
@@oliverheaviside2539 yes also the floor already wobbles in the park house with normal cars ,I sit in the car mornings and drink my coffee and make phone calls before heading off to our building and when another car drives by you can feel the floor "bouncing" so with these over weight EVs ..it is going to get very interesting and the trouble is (it is an industrial estate )to get a space on the outside car park ,which is nearer to the main entrance ,I will have to get there earlier
@@derek-press I recall an older car park in New York City collapsed because of the extra weight of EVs. The engineers designed for typical ICE vehicle weights.
Going elsewhere makes good sense. Putting EV charging on the ground floor is a really dumb move. It leaves the people and cars on the other three floors with no way to exit when there's a fire.
@@Inkling777 True but it also puts the heavier cars on the ground and first floor that can support the heavier weight better.
6 years ago, we put a $1000 down payment on a future Thesla that was never produced. They were promising $32k EV. Fortunately a few months later, we saw a documentary like this one and we withdraw our down payment to purchase a Toyoya Camry instead. So glad the EV was not available. Thanks to this info, we were not scammed into buying an EV.
EV`s are not a scam. Just like them Ford F150 trucks with the tanks on the side that burst into flames after a side collision were not a scam. It is just bad design. And you are just not very well informed.
@@bossman6174 not well informed? Hahahahaha.... that's good. At least I don't have a political agenda and I'm not profiting from EV's or lithium batteries. EV's from the 90 like the Honda and the Saturn were not scams as they fulfilled their promises, no lies on their short range, cheap acid batteries and no gizmos to fall apart. I wanted one. But auto makers are not interested in manufacturing a safe and durable EV. Also, Ttere are safe proven solutions for lithium batteries, but not a single auto maker is interested. They don't care about our safety at all. It's a SCAM, a life threatening scam and a nuisance for our society and a desaster for the environment. Here is the deal, EV buyers cannot sue the manufacturer, but non EV buyers can.
How is it a scam?
It's a scam because if every car on the planet was an EV the climate would still be changing.
I really hope they can come with some sort of separation layer, that will react with electrolyte at high temperatures and basically make battery into solid, non-flammable bricks.
That is the gist of the problem in that a specialised vehicle battery has not been developed in the hysteria of the climate panic and a lash up of torch batteries has had to do. The climate panic is an emotional thermal runaway in many ways, to match the cobbled together technology attempting to sustain it beyond current capabilities.
That's an excellent point! It is like the 'population bomb' hysteria of the late 1960s has led to almost every developed country having a below-replacement birthrate that threatens social programs caring for the aged.
That sounds like a great idea!
@@jamesquinn3414 imagine the cost......to you.
I'am no expert , but , I think that there's attempts being made w/ the individual cells being immersed in a coolant , aiding thermal regulation .
Thanks. That was very informative, yes moving them after the fire is out another major hazard.
Environmental hazards too.
EV now stands for Explosive Vehicles!!!
This is virtually inevitable under load! The power draw must match capacity and as bat gets older therm is very likely. Its surprising this isn't common. Obviously cars go threw so much during a simple drive. A mere puncture, a metallic spec/sliver/screw(a f*cking gum wrapper!) etc flies in threw the vents and is an almost guaranteed goodbye. Simply charging and a surge happens, or just one bad bat during manufacturing can also cause this obviously, but these aren't even the main reasons! The draw is astronomical compared to laptop or phone and running a large quantity in series is a caveman solution! I mean, these vehicles are ticking time bombs and this has been understood since the 60's, when we already had a better option. I don't recall immediately but the alternative is capable of 50mph and is a fune solution both for environment and general safety, but no one cared about the environment then and obviously demanded faster stringer cars. We could use that older tech if we want to drive slower more expensive cars for environment sake, but lithium ion battery EVs are bad on so many levels I want tear my hair out when i hear people bring this up like "oh see this happened what a surprise!" They lio leak toxins when not in use for extended periods, mining is toxic, processing it is toxic, and its just a massive amount of toxic when done and inevitably exploded. They are a fine thing in a laptop or a phone but their preset use in disposable vapes and cars out to be criminalized! Its such a waste to use them on cars on so many levels its frustrating to this is even debatable. Theres is literally nothing good about lio powered EVS for the environment on so many levels and I hate cars so I am not even talking from a gas lovers perspective! Using lithium ion bats in series in cars is simply a caveman solution. Musk is a fucking hustler pulling wool over boomers eyes for investments promising a better solution eventually. Theres no need we if we want ev we could have had them in the sixties and can have em easily now too just not powered by lithium ion its upsetting!
It’s environmental vengeance! The environment is seeking revenge from those who seek to destroy it by embracing the current lunacy!😅
😂
Or Extremely Volatile 😂
@@paulorchard7960i guarantee this comment was made on a device that has a lithium battery in it!!!!!!
Thank you for your expertise and explanation.
You are welcome!
There is definitely room for safety improvements, like self extinguishing materials or something...
Could you please do a vlog on the toxicity of the gas from these thermal runaways. Nice description thank you
Excellent video. The explanation was crystal clear and all the jargon was explained. Now I know engineers have a fancy term for fire -> thermal runaway. Are there tests on our EVs that we can do say quarterly to figure out if they are at risk?
What it is, is a legitimate reason woke governments should NOT be approving EVs as replacing normal cars
Lithium is a reactive metal, like sodium or potassium. Putting water on lithium will START a fire!
This is why they burn in floods
Except there is no lithium metal inside a li-ion cell, its lithium cobalt oxide as the cathode. What happens when you introduce water to that? (Hint: its not the same as with lithium metal.) What happens to lithium metal is irrelevant in this context.
@@jibbtaylor Only if the flood is with salt water, since it is way more conductive and corrosive. If you look at all the stories of EVs catching fire when submerged or partially submerged, that water is always salt water.
What a way to show the world that you have zero idea of what you're talking about..
Similar to a nuclear chain reaction, although a lot less energy
Thanks for the heads up! After watching this video, I decided to get a traditional self-charging Toyota hybrid with a NiMH battery
Twice I've bought packs of 8 of those batteries with two in each pack faulty, good quality branded ones. If I can't get 8 good batteries in a pack, how can they put 7000 in a car and they all work?
Ignorance is dangerous **** thank you for sharing
So is it possible that these things can catch on fire while you're driving them? That's a terrifying thought.
And remember, you're then stuck inside a vehicle that most likely uses electronics to unlock
People HAVE burned alive because of this and the fact that the doors WILL NOT unlock!
Anything is terrifying if you focus on the negative factors. How many normal cars have caught fire while being driven?
@@slimjim1125 it's not the fact that it catches fire. Yes, ICE vehicles also do. But what is a problem is the experience if they do & how difficult it is to handle that fire, especially once it goes into TR
@@alwynsmit3546there is an emergency mechanical door release on all new Teslas. (new as in after 2012 I believe) Mine has one.
Seems so environmentally friendly...
I work with random condition lithium cobalt cells and there are some that start heating up around 3.6 volts during charging. This is only half full so something is happening internally. This is the condition that causes thermal runaway. The bms MUST have thermal protect.
Pretty sure the EVangelists love your honest evaluations and can't wait to spread the facts among each other👌👌
I bet you feel so smug using that word.
@@slimjim1125
Truth hurt??😁😁
Soooo… dont park in an apartment underground parking facility next to another EV.
EVs will park next to our cars in our office building.
I use a lot of lipo batteries in model planes and helicopters if they are damaged they can still burn in water but if you put them in salt water it does kill them
Nothing worse than ignorance about batteries. I tip my hat to you as an airline electrical systems instructor and check airman. 👏👏
EV manufacturers have invested so much into this technology to the point that they would not admit it's a failure to store energy this way.
Have you seen the Danish Battery Briner system? Brine can be cooled to -18 centigrade without freezing, so more heat is removed more quickly than is possible with CO2. The salinity also shorts the cells, removing the energy sustaining the runaway.
very interesting to know
Imagine thinking this is the future!
The EV1 was, and is, the only ev (with easily recycled dependable, safe lead acid batteries) that would have been largely accepted by everyone and for that reason they were destroyed.
The EV1 had no where near the power or range. It started as lead acid, but moved to nickel metal hydride.
Don't panic. Sodium batteries are out and these don't burn for shit.
Is there no way to incorporate some type of fire extinguisher method for these Lion car batteries?
I am convinced this extreme heat generated by the "Thermal Runaway" of lithium-ion batteries can be harnessed to power something like a steam engine. Perhaps I should pose this suggestion to someone who understands thermodynamics and basic engineering - like Greta Thunberg, or Elon Musk.
That's probably a better use for lithium, add a little water to some and get all the energy at once.. but sort of controlled 🤔
I have owned four electric cars in the last 40 years, all had lead acid batteries. We never had this problem.
But what was the power density of those? Yea, nothing compared to what's used now.
@@slimjim1125 Correct, that's what makes lithium ion or LiFePO4 batteries more dangerous. The higher the density, the more dangerous it becomes.
Milk floats used NiFe batteries, not terribly good for storage density, but the milkman was able to distribute his milk very early in the morning.
lol a total fail from day one - let’s review - Lithium is a pure element found on the elements periodic table - all elements have properties - copper turns green over time, gold sparkles, lead melts at low temps, hydrogen is flammable - add a few protons, neutrons and electrons and right below hydrogen you will find Lithium on the periodic table and lithium has an interesting property - it ignites into flames on contact with water - silly humans - a doomed path lol 🤪🤷♂️👍
No thank you very much!
I really disagree with the term "thermal runaway" in a battery fire.
It is more realistically called a chain reaction.
Thermal runaway is more a condition where a reaction starts, and the heat produced accelerates the reaction, creating more heat, speeding up the reaction more, creating more heat, and so on.
Yes that happens in a battery somewhat as well but the "cell to cell chain reaction" component isn't a thing in thermal runaway.
The thermal runaway that occurs in a battery such as in an EV is on a per cell basis. It does give the appearance of runaway to the entire battery but that is simply not the case.
it is in a sense, still a thermal runaway, rather than simple chain reaction. A simple reactions inside the battery isn't enough to create the heat necessary to making the same reactions on neighboring cells. It is the inital internal short in the battery, either due to a phsyical, electrical or thermal abuse inside one or more cell, which starts the initial 'heat up', which, in most lithium battery, is a self-fulfilling heat source due to how exotermic the reactions are, reaching upwards of above 500C degrees at minimum, where majority of the isolators inside the battery already melted at below 200C, means more internal short, creating more heat, which in turns heating up the reactive electrolyte, combusting them with the oxygen released from all the metal oxides inside the battery which starts to decompose at such high temperature (and even faster), creating a self-generating oxygen fires, with both the electrolyte and vented gas available to fuel the fire. The extreme heat generated by even a single failing cells is high enough that in short moment, it's reaching high enough temperature for the neighboring cell to also heat up enough to melt their internal isolators, creating even more internal heat, and reintroducing the same cycle again, again and again.
The heat, rather than simple chain reaction, is the reason it is capable of this much destruction. It's the heat that melted the isolators, allowing more and more internal short happened, which generates more heat. It's also the heat that facilitates the decomposition of metal oxide, releasing their oxygen content, allowing for a fire capable of burning without external oxygen source, generating more heat.
@@danieltanusetiaji8931 Congratulations. You just described a chain reaction 🤦♂️
@@MadScientist267 chain reaction doesn't need the heat to incur the circle, thermal runaway does. Without all the component keep generating heat to incur more heat generation, thermal runaway will just be a single, one time thing. Chain reaction doesn't need heat to works. Example: Nuclear chain reaction only needs the neutron and critical mass, no heat exactly required. And in the beggining, when you describe the thermal runaway, well, it's exactly what happened inside the battery....
@@danieltanusetiaji8931 A chain reaction is any reaction that leads to more of the same reaction. The mechanism that connects them (in this case heat) is irrelevant. Stacked dominos falling is a chain reaction all the same.
@@danieltanusetiaji8931 I think you're referring to a single cell. I'm referring to the entire battery as a whole. Starts with one cell that is not happy, and before you know it, that cell's thermal runaway, yes, causes a chain reaction to start that takes the rest of the cells with it.
I can go with that. I made that point pretty clear in the original 🤷♂️
So a typical fire extinguisher is useless for rechargeable battery fires?
It doesn't need oxygen to burn, so nope
this is why i store batteries outside
Car manufacturers conduct (oh, not an intended pun) multiple failure and crash tests to assess the safety of their cars and obtain a safety rating, don’t they? ANCAP rating.
All car manufacturers know what happens with failed battery packs, don’t they?
They know how to stop and extinguish battery pack failures, don’t they?
It’s about time the EV industry explains.
EV driver just having a small fire extinguisher in the boot is obviously inadequate.
i will try to avoid parking next to teslas in the future
What about every single other EV that's out there? Or do you think that Tesla are the only EV manufacturer in existence?
You'll park next to a Rivian, an f150 lightning, an electric Hummer, a mustang, a volt....
EVs have a niche place at best right now. Mass production EVs are no where even remotely ready. They are just pushing out what the mandates are pushing for. EV's. All the research I have conducted shows me that right now, in our current state of technology, batteries are not up to this task yet. It has been independently proven that the creation of 1 EV car puts more CO2 in the atmosphere than 1 combustion style auto.
Gas engine if you don’t ever start it is cleaner than an EV.
I tip my hat to you as an airline electrical systems instructor and check airman. 👏👏
That's true, and dependng on the production type for electricity, that deficit can be overcome in as little as 8k miles in the likes of Norway/Sweden and around double that in UK and some other European countries with high renewables and nuclear output.
Why would anybody buy an EV or hybrid? Utter insanity.
Personally, I think hybrids make sense.
@@StacheDTraining It's the worst of both worlds. Still uses gasoline, but also has a huge battery that can catch fire. The cost to replace a degraded battery can be very high even in a hybrid.
I'd hate to see how much the fire insurance is😮
Never see or hear of any politicians driving them.
Well if they do they don't catch on fire just like they are seldom if ever victims of a crime, thus are soft on it. They especially seem to look the other way on white collar political crimes, if democrat, and if they and/or colleagues are partaking in it
What did they think was going to happen when they pack all that energy into tiny little boxes? This is why carrying around _potential_ energy is always going to be safer and more reliable than carrying around _active_ energy, like electricity stored in batteries. Batteries are fine when it's for a power drill, or a flashlight, but when you have huge multi-hundred pound batteries strapped to the bottom of a moving vehicle, then you're basically sitting ontop of a bomb ready to blow. Gasoline cars are more safe because the energy within the gasoline is _potential_ energy and it can do nothing until it is ignited and even then, it is very difficult to get _liquid_ gasoline to burn. Gasoline _vapors_ are what burns, so keeping the gasoline inside of a sealed container or system is the safest way to handle it, and said systems need a quick cut off device so that if a fire gets started, you can seal off the rest of the gasoline and kill the fire rather quickly.
Why aren't Battery Boxes vented? By putting in a burst disk, you are guaranteeing that hot gasses and pressure is built in the box? What if we vent the box when the first battery starts spewing hot gas?
Most boxes do have venting.
Those batteries were never invented for motor application. They were security systems only.
Man, more and more people are being forced to buy electric vehicles. People are buying electric scooters, bikes golf carts etc… These random uncontrollable fires are going to really cause havoc everywhere in the future.
great info , as always . 💪
I had a electric scooter that had a 451 W motor. It went 18 mph and I just got it like I plugged it up two hours later and start making like a hopping or popping sound. I unplug it immediately then it starts to smoke and make a hissing sound again
You just earned yourself a new sub m8
I wonder how much and what kind of pollution the gases from those burning batteries are releasing into our environment
EV's are firetraps plain and simple it these car companies would just use hydrogen or a diesel electric like trains we could not only be more fuel efficient but we would not have these death trap lithium batteries.
We would starve without electric vehicles.
Those vehicles are locomotives with large diesel or gas turbine engines making the power to spin electric traction motors. If batteries were more efficient and less dangerous, we would use those.
I believe that the Li-Ion battery is going to be replaced with something else in the near future. Toyota Prius for the first three generations used NiMH batteries and no major catastrophes have happened with those, and their reliability is amazing. The load on Li-ion batteries to power vehicles is just too much for this technology. There is no way I would even consider buying of of these current EVs as they are, in my opinion, still in beta testing phase. If a car submerged in water can actually burn, is absolutely nuts.
Environmental nightmare !
Lithium is seriously dangerous however any EV with battery storage would also be quite dangerous under fault conditions (70kW is a lot of energy)... They could keep the combustion engine and convert water into Browns gas which might work or equally, using electrolysis to separate water into hydrogen and oxygen and feed the gases directly through a hydrogen fuel cell to run an electric motor🤔🤷♂️
Ah yes Hydrogen. Hindenburg.
@@patrickgriffitt6551 Not quite, the fuel would be water and only converted into hydrogen when needed so no large amounts of gas to go boom.. maybe 🤔
@@Andykerrfield Ah. OK . now I see your concept.
No way would I buy or get one of these things for my family
My Chinese made Ariel Rider Grizzly, 2 wheel drive, dual motor, dual battery, 52v fat tire E-BIKE shorted out, caught fire, and exploded, BETWEEN MY LEGS this summer as I gently old man rode it along on a dirt road at 10 mph! Since then, dealing with the company in, imagine that, Portland Oregon, has been a 6 month nightmare of trying to get it worked on and fixed. BEWARE! E-Bikes are made "there"!
Yikes!
Unfortunately, that is the problem because these batteries are made up of many individual cells, wired accordingly to achieve high voltage and current! In my opinion, this is technically unmanageable! As shown here, one cell failure is enough!
Toxic.☠️
How does *_ANYONE GET INSHURANCE IN AN EV???_*
i have 4 ego lithium batteries and everytime i charge them it smells like something is burning and even if i sniff the charger it has a burning smell, i store them in the house cause they say the batteries don't do well in extreme weather like in my plastic shed. question is is that normal for them to stink
I would discard them they're likely to catch fire lithium ion in general is too unstable I'm staying away from it
Stop the use of cheaper yet highly explosive Lithium-ion and use the more stable Lithium Phosphate! The price saved is not worth it!
do I understand correctly that the runaway of even one cell ends up with a catastrophic failure of entire battery?
If one cell fails, the entire battery will likely fail.
@@StacheDTraining cell failure rate is 1/10 million, assuming 10 yr lifetime yields 1/100 million years. Having 10k cells in one battery yields the failure rate of 1/10000 years, or 1 vehicle per 10k per year, or 1/1000 in 10 years lifetime. Looks like 10-100 times larger than the conventional vehicles
Sure is like a chain reaction.
*And There are over 2000 in a TESLA - No thanks !* 🔥🔥🔥🔥
Google says there is over 7000 cells in a Tesla😮
@@larryjohns8823 WOW Even Worse !
WOW NOT A TESLA??
what about every other EV manufacturer? I bet you don't even know they exist 😅
Ships at sea United States Navy. 🇺🇸 A thermal runaway is an emergency alarm resulting in all hands to man firehoses or firebottles. Maintenance personnel will quickly access the overheating battery as quickly and safely as possible (before a detonation or fire occurs). A chain of sailors with gloves form a chain to the nearest catwalk. Once the offending battery is removed, this is handed as quickly down the chain of sailors and Jettisoned overboard. Yes, even aircraft can suffer from a Thermal Runaway.
A battery casing with a vent leading into a water canasta. Allowing venting and directing the flames towards a water body . Might be a good invention to anybody smart enough with the financial backing.
It will save us from being stuck with electric cars.
What about 36 volts
Disturbing! You displayed yet another video of a battery venting underneath the driver's door. That is the door that will _always_ have someone needing to exit. Don't these EV makers have enough sense to vent the hot gases well away from any of the vehicles doors?
Anyone remember chemistry class? Lithium explodes on contact with water, duh?
The public has been duped. There is a push toward solid state batteries by Toyota, but I don't know if they'll be any safer.
Only now am i beginning to like social media, i now get to hear about the EVs burning, corporate big wigs would otherwise hush it up, as would governments. 😮
how many firefighters will have to die before this things are done away with?
How many firefighter deaths have batteries caused?
They're not going away any time soon. And your comment regarding firefighter deaths is silly.
Maybe the electric cars should have a on board fire system like the race cars do
Fun Fact- Don't let a good ev fire go to waste. Allways carry plenty of marshmallows.
External combustion motor
Sooo, if heat is the enemy what happens if you took a Li-ion battery that is suffering thermal runaway and dunk it in liquid nitrogen?
Liquid nitrogen is really bad at absorbing heat.
Can you please include in your videos that EVs are much less likely to catch on fire than gas cars? Looking at the comments, people seem to be comparing EVs to perfection rather than to internal combustion cars.
I discuss the data here: ruclips.net/video/d_SpHvBfzrw/видео.html
There's also the problem that lithium explodes in contact with water...
Luckily, there is no lithium metal in lithium-ion battery.
EVs need batteries that aren't portable bombs.
This could all be solved if EV makers stopped messing with laptop batteries and used an used a dozen or so large 3.2v LFP batteries...
Is that an option- and would that be safer?
I want to believe your smarter than Elon musk…..😂
I'll stick with internal combustion engines.
Thank you very much.
What is diesel runaway?
Whats the CO2 emissions of a Tesla catching on fire?
We should know later this year.
Do you think that Tesla are the only EV manufacturer?
What year is it that all new vehicles sold in North America must be prone to explosions. 2030 or 2035 ?
What a moronic thing to say.
Best to keep theses batteries out side away from everything,not in a car in your garage,lol
Yeah, I totally want an electric car in my garage that's attached to my home. What could possibly go wrong.
What he didn't mention is that the "flammable gas" is extremely toxic.
Wouldn't you consider all flammable gasses toxic?
@@StacheDTraining Point taken. However, the degree of toxicity is the main factor. There are reports of firefighters being permanently disabled, in Australia, from breathing in the fumes from EV fires.
scarey fires from these batteries
Tick tick tick tick
It's a matter of time
And how is this good for the environment ? 🤔
Buy an e.v. and you are sitting on those...... Isn't that awesome.....
That can't be good for the environment greenies
This whole subject is littered with people that have 10 pounds of opinion and 1 pound of knowledge. They truly lack the understanding of battery management systems and battery cell construction. High-quality battery management systems vastly reduce the potential for a thermal runaway. Also, other technologies such as the battery manufacturer I work for, employs technologies such as fusible links. Each and every battery cell is connected with a tiny wire that will melt when it gets hot. This essentially eliminates the potential for a thermal runaway because all of the individual cells become disconnected from each other. And fire departments and safety officials are massively uneducated, yet they have huge opinions, not based on facts, and they come up with some of the dumbest regulations one could possibly imagine. Incompetence runs rampant when it comes to safety officials.
This makes all electric cars with lithium batteries potentially unsafe. A safer non lithium battery needs to be designed and those cars with lithium batteries should be taken off the road one would think. Tesla and other EV makers need to rethink the battery. This is just my opinion which may not count for too much. Too much is invested already to change anything and I get that. It is what it is.
