PROF. PAUL CHRISTENSEN
Through his research under the Faraday Institutionfunded ReLiB andSafebatt projects, PAC has sought to inform first responders of the risks and hazards of lithium-ion batteries and hence (hopefully) to avoid
injuries when dealing with LiB fires and explosions involving (principally) electric vehicles and battery energy storage systems. He has given more than 100 presentations to first responders across the world as well as help and advice on an ad hoc basis.
He is the Senior Advisor to the National Fire Chiefs Council and serves on
a number of UK Government and British Standards Institute working and
governance groups. He is the recipient of 2022 Motorola Foundations
Knowledge Event Series award from the Australasian Fire and Emergency
Service Authorities Council for a lecture tour of Australia, Tasmania and New
Zealand. PAC has over 180 publications in international journals and an
H-Index of 53

[@Veeger]

It's crazy to me that the rush to go green has meant the dropping of safety requirements that have been built over decades of vehicle manufacture. Lithium ion is an unsafe chemistry that has been allowed whilst we wait for solid state alternatives. In the mean time fires caused by battery thermal runaway are seen but we are told, ICE cars catch fire too , like that is a good reason to sit on a potential bomb that may just randomly explode because of a battery fault. To me, that doesn't sound "sustainable".

If EV batteries became standardized and produced by a 3'rd party manufacturer, like Bosch makes generic parts for most cars today. It would be possible to buy certified new battery modules and generic control systems. However now. the EV industry is like the automobile industry a 100 years ago. Every car maker do their cars completely in house and use unique solutions for everything. Standardized battery systems would also make life easier for firefighters.

There have been 2 high profile multistory car park fires, the most recent being Luton Airport. In both cases the fires were started by a Diesel vehicle and in the case of the Luton airport fire 1,500 vehicles were destroy and the building is being demolished. EV fires do need to be responded to in a different way to fossil fuel cars, but with the correct training and equipment they can be dealt with effectively. As for the risk of an EV fire compared to a fossil fuel file, a study in the US has found that fossil fuel vehicles are 60 times more likely to catch fire than an EV. EV battery technology is also improving and becoming safer, so the risks are continuing to fall. If you are interested, look up Lithium Ion Phosphate and in particular the BYD Blade batteries. A comment from an interview with Paul Christensen "Concerns raised by Christensen highlight the lack of distinction between electric car batteries and other lithium-ion-powered vehicles, like scooters and bikes, which often have less safety regulation associated with their battery technology."

[@sparkytas]

Actually, if an EV is designed with an extinguishing port in the rear for pumping almost freezing brine into the battery enclosure on the end of a long lance, the freezing brine electrically discharges the battery and cools it. Have they done any research into BYDs blade cells? These are meant to be significantly less flammable.

[@Eduardo_Espinoza]

[@ThePhiliposophy]

There are six types of cathodes for Li-Ion batteries. Three of which are employed commonly in EVs. One of them is LFP (Lithium Iron Phosphate), which I would consider the only reasonably safe variant. But LFP is rarely chosen, because of its low power density. The other two (NMC and NCA) have a much higher power density but are also much more dangerous. Dr. Christensen is talking about the importance of education. It would indeed help to include the distinction of different Li-Ion battery types in that education. EVs with LFP batteries should not be subject to the same restrictions as the other types. What I don't know is if the response to a unlikely LFP fire should be the same as NMC and NCA. Does it release the same amount of gas? Can it also undergo thermal runaways if the conditions are ripe for it? Or is inherently save and self-extinguishing?

I agree it's not about the ratios of EV vs ICE fires but about the difficulties in dealing with them. Thankfully the ratio's are in favour of EV's and we have time to modify designs and mitigations. Battery tech is also changing rapidly and I suspect safety will be a leading factor in design considerations. Once there was a dream of allowing everyone to have their own private personal transport so people could go where they wanted when they wanted. Governments built more roads. More cars where sold. More roads where built. More tax money was made from hydrocarbons. People could work miles away from where they lived. That dream is ending. What's really needed is cheap / subsidised / efficient public transport and the rebalance of society and jobs. What will likely happen though is things will continue as they are in this 'The Great Acceleration' - until society / economies can no longer function then everything that got us here will be abandoned like a sinking ship.

[@keyserxx]

As an EV car owner and lover this is a good video to watch. I don't own a drive way and if I did I'd park my car slightly further away from house after watching this video. In a way the visuals of thermal runaway make sense as my car battery can hold up to 64kw (usable, more actual), if I stood in front of 64x 1kw heaters I think bad things would happen as well. Huge power numbers. I do agree that home battery storage probably shouldn't exist as long as it has the potential to do that. I'm more a fan of using the car battery as the home energy storage - at least it's a bit safer that way. There is a lot of research and upcoming new batteries that are a lot safer and I think the industry does realise this. One sidenote is ICE cars do catch fire: I don't know the numbers but did see an ICE car fire about 5 years ago on the hard shoulder, only just happened maybe 2 mins before, but was well on fire, during summer, within that time it had also caught the fence, tree and field on fire, fire brigade were about 1/2 mile away while I was driving past on the other side. No mention of it anywhere in any news. How often does that happen? And what are the common causes of a random ICE fire while driving along? I guess it's not news if it happens all the time..

[@jacobheinz8236]

This is a good scary presentation for sure. I have been in the fire prevention industry for a number of years, if enough education of the public is done, of the causes of fires, most of us shouldn’t buy the furniture and mattress we all have in our homes, these are stuffed full of highly inflammable toxic foams. We shouldn’t wear those polyester fleece and puffer jackets, but we do. There’s no question that EV batteries are highly inflammable when damaged but EV batteries like those in a Tesla has a Battery Management System (BMS)to regulate charging and temperature control to prevent thermal runaway, unless it has been physically punctured. That can’t be compared to an E-Scooter, these do not have BMS. Not all lithium batteries are the same or made the same either. Fires do happen even with gas cars, in fact there has been a lot of fires with gas vehicles and many deaths too.That doesn’t mean we should also not drive gas vehicles right? So education of firefighters and users and general public of lithium batteries fires is required like all new technologies introduced. Not many of us will give up our lithium batteries operated mobile phones, our computers and tablets etc. We need lithium batteries, the issue is how they are made, maintained and used.

[@ouch9326]

these cars are not what they should be, dont waste money on mediocre , make them stop fooling around if they are gonna get your money. concept car videos... how about a video on what you guys think is the ideal car? driving efficiently is speeding up especially on more downhill-ish roads at optimal fuel level and engine RPM(RotationPerSecond), steering and braking minimally but smoothly. optimal effiency for toyota 2.4 inline 4 is 2/3 pedal down in 2k-3k rpm, cvt hybrid maintain constant rpm. not sure whats best to do this in: sport mode, fuel level is more, in eco mode its less. use EV mode if optimal combustion level would speed car too much (often, if car isnt letting you do that without the EV mode, it wont let you us EV mode.) use it a bit from a stop for smooth acceleration then when car is rolling use combustion then maybe use it a bit more. smooth acceleration is part of putting less weight on tires at a moment because: consider tire wear dust emissions and how much it cost to replace tires (most people are becoming increasingly even poorer than they already are and you can invest money into bigger money)like those "xenoestrogen endocrine disputing forever chemicals micro plastics" etc. apply less weight on tires and you'll allow more of that weight handling ability to be used for having more grip for endurance-race-pitstop-avoiding momentum preservation driving fun in the name of efficiency. being able to feel how close car is to its grip limit is good for this goal, similar to the lotus-car-enjoyers ideal. hybrid cars are arguably better than electric car because they lower use of combustion and battery mass and all materials overall without adding so much weight. weight worsens road wear damage (repairs cost emissions , money etc) , worsens crash safety for all (except few rich people who can afford super safe cars in the small chance that they are involved in crash and value their lives and have lives we can value). this is why aptera motors originally made diesel hybrid, but now sells electric cars to max profits and reputation as a "environmentally friendly brand." because batteries are not fully recyclable and combustion fuel is based on anaerobic bacteria that regenerates , which is why oil rigs go back to getting oil after abandoning the almost empty oil well years later . this is why arguably only combustion is proper, in rear mid engine weight distribution , rear wheel drive , with limited slip differential for minimal tire wear even in normal driver driving , for preserving momentum around turns more without too much slowing down by lateral (left /rights) g forces tires. genetically better population is being replaced with one that is more likley to be less loyal to each other and more loyal to selfish elites, and even they probably will be replaced with others, until theres noone left except the elites and few servants. so even hybrid seems useless. so overpopulation isnt a problem so running out of materials by over use probably wont happen. can you prove climate change is caused by human caused co2 or that its just milkovitch cycle of earths magnetic field tilting etc causing stuff like the usual natural ice ages etc? also see blackgrock esg score and their climatechnge talk, and see how they promote nonsense with ot of money, see colbert report "how blagroc conquered theworld" etc . . about climat change, see tony heller, tom nelson, suspicious observers, youtube chanels. i haff to talk like this znezorshp reasons to understand why so much nonsense if happening (in lot more ways than only car) see corbetts explaantion of climate crisis , "blackrock conauqered the world", federal reserve etc . ivor cumins, tony heller, magentic reversal news. vocational science of freedom how yoru assets are stolen from birth on odysee, yandex insteadfgoogle, , western governers university .

I doubt many EV batters have "thermal runaway" as a mechanism for a fire starting. It is more fundemental - it is Dendrites. These are deposits that can grow inside the lithium cell and if a short is created - then - the short can get red hot and catch that cell on fire; when there are many more batteries packed closely to the initially burning cell - it can catch others on fire; and that car can catch other adjacent cars on fire. It is a design flaw with Lithium cells. Most EV fires happen when it is in a garage trickle charging or parked doing nothing. There is little or no heat to dissapate. Thermal runaway would occure only after high output use; like accellerating the EV fast in a hot evironment perhaps with a load - that will cause the battery to heat up, but it is fairly few and far between you see this happen.

Edison argued that AC was far too dangerous to succeed; he even publicly electrocuted an elephant, to prove his point, and in truth, AC power has killed countless numbers, ever since its introduction. But society would be nothing like it is, without reticulated AC electricity. The truest thing that Dr Christensen suggested, was that education is key. But while AC power is just as lethal in 2024 as it was in Edison’s time, there seems little doubt that battery chemistry will be vastly different within a decade, much less a century.

In the States they are pushing huge grants to buy EV school buses, one of these days, one of them will catch fire while the bus is on its route and I shudder to imagine what a bus full of kids with only moments to escape will result in, there have already been some fires, but they, so far, have only occurred while the busses are charging or are out of service. I believe the UK had three city busses burn up recently.

[@cherryjuice9946]

An EV school bus sounds horrible, but I also worry about the new Tesla cyber truck. They say the windows are resistant to breaking. Much like a hurricane rated window, you can crack it, but you can't get through it. Stupid car doors lock themselves now days as soon as someone puts it in drive, so people are driving around with locked doors and windows that don't easily break. If such a car/truck gets in a wreck, and ignites, the passengers better hope the doors can unlock manually (since electrical system might be nonfunctional), and they know where the manual unlock lever is, and they better hope they're alert and able bodied to be able to open the door and get out. If not, the by-standers will only be able to watch them burn. Passengers can sometimes be kids too, and this thought haunts me.

thank you for this. A few months back we had a electric scooter blow out and ignite. The firefighters came in, and just let it burn. Once it was over they vented the building and removed the scooter. Our superintendent could not say what caused the fire, but the cause was on the lawn. If there is a fire in a building, should not the tenants be informed so it does not occur again? Perhaps, buildings should have storage devices or lockers for such devices? What are we to do? I have put off acquiring an e-bike or power back up because of Lithium-ion storage devices.

About a year ago or so, there was a rain event in Florida and many EVs got too wet. For the next week after the rain had stopped, there were several fires as the batteries failed. Don't know if water or moisture seeped into the batteries, or if something shorted them out and caused them to drain too fast, over heat, and ignite. I suspect moister got into the batteries because it took a few days before they started igniting. If they were shorted out, I'd expect them to ignite while still wet. At any rate, California is getting a rain event right now. The story writes itself at this point. On a positive note, most of us enjoy fire works, so it's reasonable to assume that we'll consider these EVs to be just as pretty.

I told him to put his RC car in a plastic bin in the middle of the yard, 20 feet from any structure, and run an extension cord to it when charging. He didn't listen. A couple weeks later, he heard a "pop" in his infant son's bedroom. He ran in and grabbed the child out of the crib as flames shot out of the closet. His house was burned beyond repair. Luckily they both made it out alive. If he hadn't had the previous experience and instantly identified the "Pop" sound, and known what it was and what it meant, his son would have died.

One thing most people don't know is that you should never charge a lithium battery if it is below freezing. Apparently, lithium batteries grow crystals inside, when they are charged below freezing. IF the crystals grow big enough they will short the battery causing a fire. I had two massagers that had two different voltages. I plugged the massager that used 15 volts into the charger that was 19 Volts. After a couple hours, the massager battery popped, throwing bits of hot metal out. Luckily it was sitting on a hard metal surface so it didn't damage anything else. Both chargers had the same size plugs and fit the other.

Li-FePO4 batteries are not new. They have been around for many years. ( F1 used them in 2009.) It is true that they are much less likely to suffer thermal runaway and should not catch fire. Many motorsport cars (including mine) with ic engines use them as 12V batteries to save a lot of weight c.f. lead-acid types. They have been bypassed by road vehicle manufacturers because their specific energy (joules/kg) is lower than chemistries like Li-NiMnCo. However Li-FePO4 batteries maintain their performance over many charge/discharge cycles and hold charge extremely well. So I agree that they are probably the safest bet albeit with reduced range for a given battery weight.

i dont know if its that bad but these cars are not what it should be, dont waste money on mediocre , make them stop fooling around if they are gonna get your money. concept car videos... how about a video on what you guys think is the ideal car? driving efficiently is speeding up especially on more downhill-ish roads at optimal fuel level and engine RPM(RotationPerSecond), steering and braking minimally but smoothly. optimal effiency for toyota 2.4 inline 4 is 2/3 pedal down in 2k-3k rpm, cvt hybrid maintain constant rpm. not sure whats best to do this in: sport mode, fuel level is more, in eco mode its less. use EV mode if optimal combustion level would speed car too much (often, if car isnt letting you do that without the EV mode, it wont let you us EV mode.) use it a bit from a stop for smooth acceleration then when car is rolling use combustion then maybe use it a bit more. smooth acceleration is part of putting less weight on tires at a moment because: consider tire wear dust emissions and how much it cost to replace tires (most people are becoming increasingly even poorer than they already are and you can invest money into bigger money)like those "xenoestrogen endocrine disputing forever chemicals micro plastics" etc. apply less weight on tires and you'll allow more of that weight handling ability to be used for having more grip for endurance-race-pitstop-avoiding momentum preservation driving fun in the name of efficiency. being able to feel how close car is to its grip limit is good for this goal, similar to the lotus-car-enjoyers ideal. hybrid cars are arguably better than electric car because they lower use of combustion and battery mass and all materials overall without adding so much weight. weight worsens road wear damage (repairs cost emissions , money etc) , worsens crash safety for all (except few rich people who can afford super safe cars in the small chance that they are involved in crash and value their lives and have lives we can value). this is why aptera motors originally made diesel hybrid, but now sells electric cars to max profits and reputation as a "environmentally friendly brand." because batteries are not fully recyclable and combustion fuel is based on anaerobic bacteria that regenerates , which is why oil rigs go back to getting oil after abandoning the almost empty oil well years later . this is why arguably only combustion is proper, in rear mid engine weight distribution , rear wheel drive , with limited slip differential for minimal tire wear even in normal driver driving , for preserving momentum around turns more without too much slowing down by lateral (left /rights) g forces tires. genetically better population is being replaced with one that is more likley to be less loyal to each other and more loyal to selfish elites, and even they probably will be replaced with others, until theres noone left except the elites and few servants. so even hybrid seems useless. so overpopulation isnt a problem so running out of materials by over use probably wont happen. can you prove climate change is caused by human caused co2 or that its just milkovitch cycle of earths magnetic field tilting etc causing stuff like the usual natural ice ages etc? also see blackgrock esg score and their climatechnge talk, and see how they promote nonsense with ot of money, see colbert report "how blagroc conquered theworld" etc . . about climat change, see tony heller, tom nelson, suspicious observers, youtube chanels. i haff to talk like this znezorshp reasons to understand why so much nonsense if happening (in lot more ways than only car) see corbetts explaantion of climate crisis , "blackrock conauqered the world", federal reserve etc . ivor cumins, tony heller, magentic reversal news. vocational science of freedom how yoru assets are stolen from birth on odysee, yandex insteadfgoogle, , western governers university . "divine speech" by nouman ali khan and sharif randhawa tries to understand why to become muslim , as it is what the troublemakers seem to counter most.
