Have an exit behind you when you’re trying to extinguish a fire. So glad you said that. I’ve never been in that position, but that’s never occurred to me. Seems obvious now that it’s been pointed out but it might not occur to me in a crisis. Thank you.
And know how to work your extinguisher. Think PASS! PULL the safety pin/tab, AIM at the base of the fire, not the smoke or top of the flames, SQUEEZE the handle/lever to start spraying the extinguishing agent, and SWEEP the spray back and forth at the base of the fire.
Did you see the Hydraulic Press Channel crushing lithium ion batteries with his press? It was overseen by his local fire department, as they were interested in the results, and the results were quite interesting. The experimentation put heavy wear and tear on his 50 ton press, and so now he's got a new 300 ton press, in a bunker.

Well at least we know for sure it was not in thermal runaway because if it was an ordinary home fire extinguisher would have had pretty much no effect on it. The house would probably be ash on the ground!
BMS systems can lock out so you have to give the battery a short temporary zap to ger the internal mosfet to turn on again so it can be charged in it's traditional method. I suspect the Teslas main battery pack is what normally keeps that small battery charged. The 16V is likely 4 cells which would actually be 16.8V [4.2V X 4 = 16.8] you can actually get closer to 12V by putting 3 cells in series which would be 12.6V. [4.2V X 3 + 12.6V]
If you want NMC/NCA batteries to last for a long in a float-charge type situation like an EV that is plugged in whenever not in use, you don't want to charge them much beyond 4V per cell. Just like the main lithium batteries, it is the first and the last 10-20% of the charge-discharge cycle that puts the most strain on the graphite electrodes.

Fun Facts: a lead-acid or AGM vehicle battery rated at "12 Volts", is actually supposed to test at about 12.65-12.8V nominal to be 100% charged. A "12V" LiFePO4 is actually a couple of volts higher, so 100% charged on these is 14.4V. So you see the range DrHarry T is working with in real hardware. 🙂

Well, a conventional automotive 12volt charger can output 15-16 volts, I’m speaking of an old school iron transformer shop charger. Newer devices typically employ electronics, and will stay below 15 volts.

If the external source was outside a specified range or fluctuated that is likely, or the internal BMS could have failed and overcharged and or faulty cell could be the other scenario. as a electrician I am aware or the issues with these cells and the charging methodology, the other unknown is if the BMS used active or passive charging for the pack. maybe something in the above helps. Thanks for highlighting this one. Look forward to any updates.
@@StacheDTraining I read the plate on the battery as 16v yes you are correct prismatic being rated 3.6 to 3.8v per cell, The charging methodology should remain the same just different peak voltages, love to know the cause of it though!
Maybe the BMS was similar to those supplied on Boeing dreamliners and failed short circuit due to bad design or bad QC. The better ones are designed to fail open circuit.
@@IfitwerksWe dont know the current charging limits near the higher (full) voltages. Would need some manufacturer data sheets. If its a system-integrated EV component then that information may not be available to consumers.
After Googling how to charge a Tesla 16V lithium cell at home. I found out that you need to heat the package with a propane torch, melt the glue, to open the package. Then you charge the circuit board directly. I'm thinking the propane might explain the "explosion".
Either they bought a cheap 120vac "tesla charger" from china off the internet, or they took an extension cord and stripped the sheathing off to run the wires directly into the battery terminals and then plugged the other end into the wall.
Conventional lead-acid batteries are actually more like 2.2 volts per cell (often a bit more) when fully charged, so a 6 cell battery at full charge would be at least 13.2 volts. If the voltage is measured immediately after full charging is complete, a reading of between 14 volts and 14.4 volts is not unusual, though it doesn't stay that high for long: If you leave a time gap of an hour or two between disconnecting the charger and measuring the voltage, it is likely to drop back down to about 13.5 volts, even if the battery is not connected to anything during that time. If you draw a few amp-hours from it (like connecting a 12 volt halogen light bulb for an hour or two), the measured voltage is likely to drop back down to about 13.2 volts. However, if the battery gives a measurement of less than 13 volts immediately after being fully charged, then there is either something not quite right with the battery itself or with the charger. It could be that the charger is not delivering the voltage it should - if the charger output only measures 13 volts, then the battery voltage will never go above that, no matter how long you leave the charger connected. Or it could be that one of the cells is damaged and therefore not contributing much to the total battery voltage. Even if the damaged cell is not making any voltage at all, 5 cells at 2.3 volts per cell still adds up to 11.5 volts. Of course it is unlikely that the damaged cell is contributing nothing at all unless is is completely shorted. Say for example the damaged cell is giving about 1 volt and the other 5 cells are charged up to 2.3 volts per cell: That adds up to a total of 12.5 volts. So if you have a battery which gives a reading of only 12.6 volts after being fully charged, and there is nothing wrong with the charger, then that battery most likely has a damaged cell. Also, and this is just a small point compared to the above, a lead-acid battery charger does not need to output quite as high as 15 volts: Most of them will give about 14.4 volts. The voltage of a car electrical system with a healthy, functioning alternator should be about the same - most "12 volt" alternators are actually calibrated to make 14.4 volts, precisely because this is what the charging circuit for the battery needs.
@@tonycs-9 Reconditioning voltage for a 12V lead acid battery is 15.8V. The voltage required to reach full charge is dependent on the charge current, battery static voltage and battery internal resistance. 14.7 is the usual maximum open circuit voltage of a lead acid battery but to reach this you need to supply significantly higher charge voltages (and smart chargers switch off charge periodically to check this). Voltage doesn’t “boil” batteries, current does.
Tesla owners are the kind of people that “think” they’re smart enough to understand electricity and wire their house… but dumb enough to not understand environmental impact.🤷♂️
Any battery can be “recharged”... either it’s chemical and that means to revert the ionization from pole/metal to pole/metal (sulfate management)... depending on it’s design... Or by correct voltage/amperage management when it’s Lithium design (electronic control with in the battery too). They used an outside charger... which one? I believe I can recreate the same failure with one of those old robust chargers which destroyed regular car batteries... which are scary. But I think they used an older Smart Charger type which didn’t had Lithium in it’s Type selection. But even those smart chargers can operate with the batterie connected to the vehicle... unless the person removed it from “a friends” vehicle and carried it to his garage for charging. As always it could have been worse... after 15 years or more of lithium batteries on our Smart Phones... how come people still don’t have a clue of how they work? “People don’t have a clue”... “Charging the battery” is such a wrong thing to say, because it’s a chemical/electrical process... what’s lost when a battery is wasted is the acid and metal (when put to extreme usage and age)
Even a normal lead-acid battery can explode from the hydrogen during charging. I had it happen one time. Inside the battery, the lead plates can crack where they connect to the outer terminals. If under load, or, especially charging which creates the gases, that crack can make a spark and ignite the hydrogen and oxygen inside and blow the battery apart with acid everywhere. Luckily, in my case, it was a small lawnmower battery and I was wearing safety glasses and damage was minimal.
I have a few older Optima yellow top batteries. They're lithium and one is very big and gets used in various testing. My oldest one that I've used for running my diesel truck, testing my old car, working on other people's cars, working on my tractor, and a bunch of other random things. I charge it in the garage for a reason. One is a 7 year old big lithium d31t battery and the one in my daily is a used 16 year old yellow top with a worn tag. They can go boom at any moment. The most smoke detectors are all around the garage, which is connected to the house. Just please be careful with anything that can hold a charge, even lead acids. Edit: I put them on concrete for a reason.
What disturbed me in this video was the flimsy cover over the indicated positive terminal for charging the battery. How easy would it be to dislodge that cap and ground the battery while working on the vehicle? That's a thin strap that's just popped onto a plastic stub or something. I can see it easily twisting off and the cover being lost as a consequence. I inadvertently shorted a Lipo battery for a brief second once, and it melted the wire (I turned it into a recycling center afterward). I don't know the C rating of these batteries, but I imagine it's considerably more than that little RC pack I was messing with. That entire setup looks like a fire waiting to happen to me.
0:25 Common Lead Acid batteries (as most of us know), are also NOT 12 VDC .. their actual voltage is 13.8 VDC ... The system has to be at least roughly 14 VDC to keep it charged up.
156 - would not be hard to rig a couple of wires to spade connectors and stick them in the + and - slots. If he hooked them up backwards I could see an explosion sure. Charging in the kitchen, um no. I charge any battery outdoors on my patio wall, nothing that can burn nearby in case it goes boom.
The ultimate problem is untrained individuals doing things they shouldn't be doing. The likelihood of this DIY mechanic cheapskate maneuver happening again in the future? Highly probable. As a professional technician I see unqualified people screwing things up already. That only costs a little money. Burning your house down or worse injury or death... stupid.
@1:53 It is very simple to hook leads to that battery. Just from the picture simple male spade connectors can be inserted and if you look closer on the inner part of each connector you may even get away with alligator clips. There seems to be other pin connectors between the two large connectors which may talk to the BMS or have a different function, or no function at all. They may give a temperature or Ohm value, be part of a relay or circuit. It's hard to say with no schematic or pinouts, therefore one should not mess with this battery if they do not understand the wiring. But to just hook up power, that part is very simple with this battery. What happens after you hook up power?...seems to make a BBQ in the kitchen. If you are going to experiment with a Li-Ion battery don't do it in the kitchen...LOL You would think the guy would spend 30 mins on the internet to find out what the pinout is and how to charge it outside the car if need be. It seems he didn't even read the manual the car came with. This is what happens when you experiment and have no idea wth you are doing.
Lithium batteries when they internally go shorted they will not charge or discharge, they will become a resistor and heat up, this will lead to thermal run away and possible explosion of the cell if you force charge the battery. A 12v charger lead acid charger will charge a battery not matter what state it is in. This battery Tesla uses has a battery monitor, not a bms, so that is why it may have exploded. You can charge this battery by using lugs or paper clips and running them to the charger leads, its not impossible.
Probably just the BMS circuit that blow up, could easily be the battery cells that gave the BMS a real explosive amount of electrisity for a moment. Circuit boards can get quite explosive if mounted inside a tights sealed compartment if given enough energy. Can see there are extra pins in the plug there to communicate with the battery. But its stupid of tesla to just don't use a normal lead acid battery so things like this can be fixed by the owner.
You can charge it with a regular charger but must monitor the voltage in real time, the second it hits its voltage you must stop as a proper Lithium charger switches from the constant current phase to the constant voltage phase where it incrementally backs off the current till voltage is once again achieved and keeps doing so till voltage is achieved with almost no current. A regular automotive charger will not do this and that is where the danger is, if you know what you are doing then its ok, if in any doubt dont attempt it if you like your house.
This is a lithium ion battery not a cell, this obviously has internal circuitry for overcharge, overcurrent, low current, cell balancing, undervoltage etc. From what I'm hearing here it's obvious that the said circuitry has failed. We all have to be more aware of the dangers of lithium battery technology, don't take any chances, keep on watching and learn from the mistakes....
That’s why Tesla’s have jump start connectors on the car. The jump start connectors were added because the old lead acid batteries died and immobilised the vehicle if the 12V supply to the onboard computer wasn’t available (just like the battery failing in your ICE car). Tesla recommends that they be left on charge below 0C to keep the battery heater active (exactly the same as an engine block heater in an ICE vehicle).
Lithium battery fires are electrical ion fires and therefore cannot be put out with water. Also water plus electricity is a dangerous thing yet still water is used on these fires. Never use water on a chemical fire. My advice is dry powder, but seek advice from a professional.
Thing is you should never charge a lead acid battery in your kitchen either! They gas off hydrogen and oxygen during charging 😮 a face full of battery shards and sulfuric acid is best avoided
Do I listen to this fireman about how to charge a lithium ion battery or someone with a PhD in electrical engineering? Hmmm tough one. I would however charge it the way the manual suggests.
What PhD EE? I've known a few of those, and I'd think twice about them winging it on a system they are not versed on. He - the Fireman - showed some pages from the Tesla manual. This wasn't a tutorial on how to charge, I think he was just making a point to not be a bonehead.
@@randydewees7338 I would however charge it the way the manual suggests first and if that didn't work to see if I could actually charge it I would use a charger where I could limit both current and voltage as I have done in the past to recover lithium ion battery packs I have been gifted as they were "faulty" for the home solar system that runs my home that cost 3000US to install. The manuals say not to mix lead acid, lithium ion and lifepo batteries on the same system but so far I have had no problems. As to your comments on PhdEEs it's always fun to try and repair something for a chap who was one of 3 or 4 on the design team for the mark 1 model prototype before it was productionised after they have already had a go at it:)
Firefighters do a LOT of training on how to manage Li batteries in cars and structure fires when confronted with them in crashes and fires. Part of that training involves study on the construction of the batteries and how they are installed and how the charging systems work. When I did my classes, our tutor was a PhD in electrical engineering from a large UK university with a specialization in Li battery systems from cell phones to cars to huge Li battery storage systems. He is considered the leading researcher in emergency response to Li battery fires. Please do not assume what you don't know.
@@elinor6525Fire Fighters haven’t been doing training on lithium ion battery fires - that’s the problem. Training is needed but isn’t being given. Water makes lithium fires WORSE. Ditto carbon dioxide. Dry chemical extinguishers are the way to go but creat a horrible mess.
Of course it doesn't have a traditional AGM battery. Why use technology that has decades of development and deployment and is one of the best and safest ways to provide 12V power to 4 wheel mode of conveyance.
How safe are those hugh batteries on the side of the house. When big batteries like that go they are like a bomb. Look for battery fires on youtube and you'll see what I mean.
@@allangibson8494Yes and No. The manufacturer has to make sure that only suitable connectors can be attached to the battery, with correct chargers. We all know people can by pass them, but they have to make sure that by passing the correct way is troublesome and not worth the effort. You have low amperage plugs that do not fit in high amperage sockets, and high amperage plugs will not fit low amperage sockets. The battery with just two slots was an accident waiting to happen.
@@tonysheerness2427 That is an “idiocy” issue. Like sticking a finger in a power point. Power points tend to improve the gene pool that way by creating another “Darwin Award Winner”. This is a special socket and I will bet what caught fire was either the cable or the explosive disconnector in the battery (yes Tesla’s have explosive charges in the battery packs to cut off power in a collision).

If the lithium battery was 16 volt then you would need a charger that gave out around 18 volts, if the guy tried to use a 24 volt lead acid charger then danger would ensue, not a smart idea. Gaz UK
One day they will get this battery thing figured out. They got the power train pretty much perfected. The biggest problem is they connected electric vehicles to this climate nonsense. Keep politicians and legacy media out of innovation .

You can't tease me with the video of the smoking EV without showing it popping its top! That's the best part!
I'm hoping to recreate the failure in a future video.
Your teaching method is genionly Amazing sir
There’s no safety device that a competent tradesmen can’t bypass .
Inappropriately knowledgeable, rather than competent, but yes.
After Googling how to charge a Tesla 16V lithium cell at home. I found out that you need to heat the package with a propane torch, melt the glue, to open the package. Then you charge the circuit board directly. I'm thinking the propane might explain the "explosion".
I think I can workout why in the kitchen, I bet they used two kitchen knifes in the terminals to clamp the charger onto.
😶 Absolutely possible.
Either they bought a cheap 120vac "tesla charger" from china off the internet, or they took an extension cord and stripped the sheathing off to run the wires directly into the battery terminals and then plugged the other end into the wall.
12V "lead acid" batteries are actually 12.6VDC at full charge. 6 cells X 2.1V/cell.
12V Lead acid batteries need just over 15V to fully charge to their nominal 13.6V fully charged state in a reasonable time.
Conventional lead-acid batteries are actually more like 2.2 volts per cell (often a bit more) when fully charged, so a 6 cell battery at full charge would be at least 13.2 volts. If the voltage is measured immediately after full charging is complete, a reading of between 14 volts and 14.4 volts is not unusual, though it doesn't stay that high for long: If you leave a time gap of an hour or two between disconnecting the charger and measuring the voltage, it is likely to drop back down to about 13.5 volts, even if the battery is not connected to anything during that time. If you draw a few amp-hours from it (like connecting a 12 volt halogen light bulb for an hour or two), the measured voltage is likely to drop back down to about 13.2 volts.
However, if the battery gives a measurement of less than 13 volts immediately after being fully charged, then there is either something not quite right with the battery itself or with the charger. It could be that the charger is not delivering the voltage it should - if the charger output only measures 13 volts, then the battery voltage will never go above that, no matter how long you leave the charger connected.
Or it could be that one of the cells is damaged and therefore not contributing much to the total battery voltage. Even if the damaged cell is not making any voltage at all, 5 cells at 2.3 volts per cell still adds up to 11.5 volts.
Of course it is unlikely that the damaged cell is contributing nothing at all unless is is completely shorted. Say for example the damaged cell is giving about 1 volt and the other 5 cells are charged up to 2.3 volts per cell: That adds up to a total of 12.5 volts.
So if you have a battery which gives a reading of only 12.6 volts after being fully charged, and there is nothing wrong with the charger, then that battery most likely has a damaged cell.
Also, and this is just a small point compared to the above, a lead-acid battery charger does not need to output quite as high as 15 volts: Most of them will give about 14.4 volts. The voltage of a car electrical system with a healthy, functioning alternator should be about the same - most "12 volt" alternators are actually calibrated to make 14.4 volts, precisely because this is what the charging circuit for the battery needs.
@@allangibson8494 15 volts will start to boil the electrolite in a 12v battery.
@@tonycs-9 Reconditioning voltage for a 12V lead acid battery is 15.8V.
The voltage required to reach full charge is dependent on the charge current, battery static voltage and battery internal resistance. 14.7 is the usual maximum open circuit voltage of a lead acid battery but to reach this you need to supply significantly higher charge voltages (and smart chargers switch off charge periodically to check this). Voltage doesn’t “boil” batteries, current does.
Tesla owners are the kind of people that “think” they’re smart enough to understand electricity and wire their house… but dumb enough to not understand environmental impact.🤷♂️
Any battery can be “recharged”... either it’s chemical and that means to revert the ionization from pole/metal to pole/metal (sulfate management)... depending on it’s design...
Or by correct voltage/amperage management when it’s Lithium design (electronic control with in the battery too).
They used an outside charger... which one?
I believe I can recreate the same failure with one of those old robust chargers which destroyed regular car batteries... which are scary.
But I think they used an older Smart Charger type which didn’t had Lithium in it’s Type selection.
But even those smart chargers can operate with the batterie connected to the vehicle... unless the person removed it from “a friends” vehicle and carried it to his garage for charging.
As always it could have been worse... after 15 years or more of lithium batteries on our Smart Phones... how come people still don’t have a clue of how they work?
“People don’t have a clue”...
“Charging the battery” is such a wrong thing to say, because it’s a chemical/electrical process... what’s lost when a battery is wasted is the acid and metal (when put to extreme usage and age)
Even a normal lead-acid battery can explode from the hydrogen during charging. I had it happen one time. Inside the battery, the lead plates can crack where they connect to the outer terminals. If under load, or, especially charging which creates the gases, that crack can make a spark and ignite the hydrogen and oxygen inside and blow the battery apart with acid everywhere. Luckily, in my case, it was a small lawnmower battery and I was wearing safety glasses and damage was minimal.
My man took a standard power cord stripped it, and stuck the wire in. Simple as lol
Anything is possible.
I have a few older Optima yellow top batteries. They're lithium and one is very big and gets used in various testing. My oldest one that I've used for running my diesel truck, testing my old car, working on other people's cars, working on my tractor, and a bunch of other random things. I charge it in the garage for a reason. One is a 7 year old big lithium d31t battery and the one in my daily is a used 16 year old yellow top with a worn tag. They can go boom at any moment. The most smoke detectors are all around the garage, which is connected to the house. Just please be careful with anything that can hold a charge, even lead acids. Edit: I put them on concrete for a reason.
At 3.6 V per cell, wouldn't the battery have to be either 4 cells at 14.4v or 5 cells at 18.0v?
Another intelligent person who didn't read the handbook 🙄
Sadly, I think the handbook is only available on the in-car screen. The screen is powered by the low voltage system. Catch22?
WHY was it in your kitchen???
What disturbed me in this video was the flimsy cover over the indicated positive terminal for charging the battery. How easy would it be to dislodge that cap and ground the battery while working on the vehicle? That's a thin strap that's just popped onto a plastic stub or something. I can see it easily twisting off and the cover being lost as a consequence.
I inadvertently shorted a Lipo battery for a brief second once, and it melted the wire (I turned it into a recycling center afterward). I don't know the C rating of these batteries, but I imagine it's considerably more than that little RC pack I was messing with.
That entire setup looks like a fire waiting to happen to me.
It's more robust than most terminal covers in traditional vehicles.
Not everyone has a garage. As a Senior we now live in a basement suite. Issues can happen 😊
I wonder if they opened up the battery to bypass the BMS
0:25 Common Lead Acid batteries (as most of us know), are also NOT 12 VDC .. their actual voltage is 13.8 VDC ... The system has to be at least roughly 14 VDC to keep it charged up.
Size is difficult to judge, but could a US 2 pin plug be forced in the battery socket? Bad design if it can.
156 - would not be hard to rig a couple of wires to spade connectors and stick them in the + and - slots. If he hooked them up backwards I could see an explosion sure. Charging in the kitchen, um no. I charge any battery outdoors on my patio wall, nothing that can burn nearby in case it goes boom.
The ultimate problem is untrained individuals doing things they shouldn't be doing. The likelihood of this DIY mechanic cheapskate maneuver happening again in the future? Highly probable. As a professional technician I see unqualified people screwing things up already. That only costs a little money. Burning your house down or worse injury or death... stupid.
I really wonder about that guy. Reminds me of the saying 'a little knowledge is a dangerous thing'
@1:53 It is very simple to hook leads to that battery.
Just from the picture simple male spade connectors can be inserted and if you look closer on the inner part of each connector you may even get away with alligator clips.
There seems to be other pin connectors between the two large connectors which may talk to the BMS or have a different function, or no function at all. They may give a temperature or Ohm value, be part of a relay or circuit. It's hard to say with no schematic or pinouts, therefore one should not mess with this battery if they do not understand the wiring.
But to just hook up power, that part is very simple with this battery. What happens after you hook up power?...seems to make a BBQ in the kitchen. If you are going to experiment with a Li-Ion battery don't do it in the kitchen...LOL
You would think the guy would spend 30 mins on the internet to find out what the pinout is and how to charge it outside the car if need be. It seems he didn't even read the manual the car came with. This is what happens when you experiment and have no idea wth you are doing.
Lithium batteries when they internally go shorted they will not charge or discharge, they will become a resistor and heat up, this will lead to thermal run away and possible explosion of the cell if you force charge the battery. A 12v charger lead acid charger will charge a battery not matter what state it is in. This battery Tesla uses has a battery monitor, not a bms, so that is why it may have exploded. You can charge this battery by using lugs or paper clips and running them to the charger leads, its not impossible.
Ugggg, why are they changing so much in these cars???
Probably just the BMS circuit that blow up, could easily be the battery cells that gave the BMS a real explosive amount of electrisity for a moment.
Circuit boards can get quite explosive if mounted inside a tights sealed compartment if given enough energy.
Can see there are extra pins in the plug there to communicate with the battery.
But its stupid of tesla to just don't use a normal lead acid battery so things like this can be fixed by the owner.
You can charge it with a regular charger but must monitor the voltage in real time, the second it hits its voltage you must stop as a proper Lithium charger switches from the constant current phase to the constant voltage phase where it incrementally backs off the current till voltage is once again achieved and keeps doing so till voltage is achieved with almost no current.
A regular automotive charger will not do this and that is where the danger is, if you know what you are doing then its ok, if in any doubt dont attempt it if you like your house.
He brought the battery into his kitchen to charge it. Obviously he used 2 forks.
Anything is possible!🤣🤣
I have CO2, BCF (and BA Equipment) powder, and Halon extinguishers due to the work I do at home.
This is a lithium ion battery not a cell, this obviously has internal circuitry for overcharge, overcurrent, low current, cell balancing, undervoltage etc. From what I'm hearing here it's obvious that the said circuitry has failed. We all have to be more aware of the dangers of lithium battery technology, don't take any chances, keep on watching and learn from the mistakes....
Lithium batteries do not take charge below -+0 Celsius. thats whay thy get low in winter, to low to get the car going...
That’s why Tesla’s have jump start connectors on the car.
The jump start connectors were added because the old lead acid batteries died and immobilised the vehicle if the 12V supply to the onboard computer wasn’t available (just like the battery failing in your ICE car).
Tesla recommends that they be left on charge below 0C to keep the battery heater active (exactly the same as an engine block heater in an ICE vehicle).
He probably has a charger for RC hobby and used that. Rigged it up with some home made connection and had a fire. Not the battery but human error.
At least it's green and pollution free!
Owner actually lucked out in a number of ways, even though his house is now a Haz-Mat site. Wonder what his insurance did with his claim?
I see you used Tesla for clickbait. Acurate title: Stupid DIYer bypasses all battery safty systems and sets house on fire.
Not so cool If that burn down your House.
"Engineered systems"...engineered by crayon eaters.
looks like standard spade connectors to me
Lithium battery fires are electrical ion fires and therefore cannot be put out with water. Also water plus electricity is a dangerous thing yet still water is used on these fires. Never use water on a chemical fire. My advice is dry powder, but seek advice from a professional.
If the managed to put that battery out with a fire extinguisher there was no lithium fire, probably just the bms board or the charger burning
Thing is you should never charge a lead acid battery in your kitchen either! They gas off hydrogen and oxygen during charging 😮 a face full of battery shards and sulfuric acid is best avoided
Do I listen to this fireman about how to charge a lithium ion battery or someone with a PhD in electrical engineering?
Hmmm tough one. I would however charge it the way the manual suggests.
What PhD EE? I've known a few of those, and I'd think twice about them winging it on a system they are not versed on.
He - the Fireman - showed some pages from the Tesla manual. This wasn't a tutorial on how to charge, I think he was just making a point to not be a bonehead.
@@randydewees7338 I would however charge it the way the manual suggests first and if that didn't work to see if I could actually charge it I would use a charger where I could limit both current and voltage as I have done in the past to recover lithium ion battery packs I have been gifted as they were "faulty" for the home solar system that runs my home that cost 3000US to install. The manuals say not to mix lead acid, lithium ion and lifepo batteries on the same system but so far I have had no problems. As to your comments on PhdEEs it's always fun to try and repair something for a chap who was one of 3 or 4 on the design team for the mark 1 model prototype before it was productionised after they have already had a go at it:)
@@randydewees7338 Valid point Randy😀
Firefighters do a LOT of training on how to manage Li batteries in cars and structure fires when confronted with them in crashes and fires.
Part of that training involves study on the construction of the batteries and how they are installed and how the charging systems work.
When I did my classes, our tutor was a PhD in electrical engineering from a large UK university with a specialization in Li battery systems from cell phones to cars to huge Li battery storage systems. He is considered the leading researcher in emergency response to Li battery fires.
Please do not assume what you don't know.
@@elinor6525Fire Fighters haven’t been doing training on lithium ion battery fires - that’s the problem.
Training is needed but isn’t being given. Water makes lithium fires WORSE. Ditto carbon dioxide.
Dry chemical extinguishers are the way to go but creat a horrible mess.
I keep a Lithex Fireextinguisher next to my desk.
Just don't buy an electric car, problem solved.
Of course it doesn't have a traditional AGM battery. Why use technology that has decades of development and deployment and is one of the best and safest ways to provide 12V power to 4 wheel mode of conveyance.
It's heavy.
AGM batteries die in cold weather.
Tesla tried those and dead cars because of dead lead acid batteries was the result.
You say there were residuals scorch marks left, no doubt i bet he touched cloth 😁👍
“…Raises a lot of questions on this incident and how it happened”
Stupidity, that’s how.
So don’t charge them, even though they’re low voltage, because they might
Blow up. Perfect
How safe are those hugh batteries on the side of the house. When big batteries like that go they are like a bomb. Look for battery fires on youtube and you'll see what I mean.
Many fires in store for the future
No photo's, maybe it was all a dream.
Not a Tesla fan but in this instance I have to side with Tesla.
I have a fire extinguisher in the bedroom, so I can get to an exit!
These Li-ion battery vehicles are new technology not understood by motorists.
Not ready for the vehicle market yet.
Not understood by anyone.
You could say that about any vehicle, look at channels like "Just Rolled In" to appreciate the depth of human stupidity when it comes to vehicles.
That’s not a “technology issue” - it’s a “training issue”.
@@allangibson8494Yes and No. The manufacturer has to make sure that only suitable connectors can be attached to the battery, with correct chargers. We all know people can by pass them, but they have to make sure that by passing the correct way is troublesome and not worth the effort. You have low amperage plugs that do not fit in high amperage sockets, and high amperage plugs will not fit low amperage sockets. The battery with just two slots was an accident waiting to happen.
@@tonysheerness2427 That is an “idiocy” issue. Like sticking a finger in a power point. Power points tend to improve the gene pool that way by creating another “Darwin Award Winner”.
This is a special socket and I will bet what caught fire was either the cable or the explosive disconnector in the battery (yes Tesla’s have explosive charges in the battery packs to cut off power in a collision).
Buy a 2 billion foot extension cord and charge it downwind the next county over . . .
A little (out of date) information can be very dangerous.
I love tesla 😍
As an engineer I try to make things "idiot proof"
But people keep on making better idiots
We can only do so much.
Lithium Ion batteries ALWAYS have the potential to become a thermal BOMB!
Looks like now Tesla EV have twice the explosion risk in the car....
So the guy has an expensive golf buggy with no battery 😂.
Tesla battery , A kitchen, Battery Charger, don't need to be a psychic 😎.
Yea, this was the acc battery not the main one. AIUI, gotta take the car apart for that one, since it is "part" of the frame, and it weighs a ton+.
Wonder if his homeowner's insurance covered it?🤔* And a big NO for any Tesla warranty. LOL
*people do do dumb chit, alot
Nu surprise. There will always be "handy guys" regardless the matter is batteries or gas tanks. A few years ago such a "handy guy" made an adapter for his camping gas tank so it could be refilled at a gas car station. The result was "kaboom" and loss of life.
The last idiot is never born....
Pretend, it's called jerry rigging for a reason
och ....
Hey yall watch this!
In the old days when they had horses the robbers never used a donkey to get away , these days robbers not that smart
2 butter knifes
If the lithium battery was 16 volt then you would need a charger that gave out around 18 volts, if the guy tried to use a 24 volt lead acid charger then danger would ensue, not a smart idea.
Gaz UK
Li-ion 12 volts can be used for any cars. It didn’t make any difference to the story that it was a Tesla.
It's relevant because that specific battery is what Tesla uses. Very few cars use lithium-ion on the low voltage side. Mostly due to cost.
Tennet and me bad 😇
StacheD is resorting to click bait. So sad as this was a very trustworthy channel.
Why on earth do people buy this garbage? It is the iphone of cars except super dangerous.
One day they will get this battery thing figured out. They got the power train pretty much perfected. The biggest problem is they connected electric vehicles to this climate nonsense. Keep politicians and legacy media out of innovation .
'Idiot proof' depends on the proof of the Idiot. 😢
using a fire extinguisher on a lithium battery don't work. Soon as the reaction gets underway you ain't stopping it easy. Honestly, you get a lithium fire, GET OUT ASAP
don't be a hero, you won't win
Reading the manual can be helpful but men rarely do that. They wanna get to work. It doesn't even help if the wife reads the manual. Either that takes too long or the man doesn't listen because he already knows everything and his wife is telling crap anyways 😂
I won't buy tesla soon, even the low voltage battery are different. I don't think its cheap nor reliable.
