I just love your videos, and I'm not an engineer. I'm just a 77 year-old grandmother waiting for my Tesla 3 RWD to be delivered this September. I'm so impressed with the Tesla technology. Can't wait for the next video!
Hi Marguerite! thanks for watching.
Smart lady!
I camp in my tesla from time to time at great viewpoints then sketch/paint the views! It’s awesome 😎
@@cathyjones4702 That's not exactly true
Once you go EV, you will never go back. Especially a Tesla with it's easy, reliable, and fast charging.
Following along with the tear down, very interesting. I will note that liquid nitrogen is no where near absolute zero, it's −196 °C (− 320 °F, 77 K). That may be cold enough for this recycling process but if you really want closer to absolute zero you need liquid helium which is -269 °C (−452 °F, 4 K).
No one will be wasting helium to cool down batteries for recycling.
ya, the details were off - the low temperature isn't so that the materials can shatter, the low temperature stops or greatly slows down the chemical reactions - so that crushing it doesn't just short everything out and cause a thermal runaway from the residual charges in the batteries.
Every drop in temp by 10 degrees C, halves the chemical reaction rate.
@@KenLord Actually, the low temperature of a liquid nitrogen bath is used to make composite materials brittle order to crush them. The cold temperature serves two main functions in order to brake complex artifacts apart: First the different expansion coefficients of each material breaks them apart at their contact surfaces because of different rates of contraction. Secondly, the cold temperature makes most amorphous polymers very brittle when a certain threshold temperature is reached, called the glas transition temperature tg. Most rubbery materials will become so brittle that a slight hammer stroke will pulverize them. So in the end, when you expose something like this battery pack to liquid nitrogen and than start hammering it I guess that pink polymer stuff will just pulverize immediately and the metallic components will fall apart into pieces that are made of aluminum, coper, steel aso
@@ParameterGrenze ok cool ... BUT LITERALLY NO. It's about not causing a thermal runaway from shorting out the residual charges in the batteries. After that it's just a freaking jaw crusher, or multiple stages of commonplace crushing equipment chewing away at it all.
You learn about how temperature affects reaction rates (Every 10 deg C cooler halves the rate) in high school chemistry, or at the latest in 100 level university chemistry.
There's nothing inherently difficult about pulverizing the materials that would require that it be so cold to enable it to shatter. This stuff isn't Vibranium.
The prototype liquid nitrogen system made by a startup company was shown off in a Now You Know episode a year or two ago, with the purpose of it all being exactly what I've described. I'd provide the link if I had it.
@@ParameterGrenze My understanding is that recycling tires involves freezing the tire with liquid nitrogen and crushing it to separate the metal belts from the rubber.
There must be thousands of engineers like me really enjoying these videos. Thank you Cory & Sandy!
Well, I'm not an engineer but I sure enjoyed their seeming amazement at what they're trying to take apart. And hats off to Elon! He's upended the need for a patent. I mean, if someone can't break down your contraption to figure out how it works, why get a patent?
And even more engineers (like me) who wince at the clueless statements such as the claim that liquid nitrogen is "just a little bit above absolute zero".
Well, I am not a professional engineer, although I played one in Transportation and Environmental Protection for state government. I have been taking things apart to see how they worked since I was a child. Sometimes I had to get my very smart father to help me get it back together again, but I was learning. I get the feeling that these guys (and many who watch them) had a similar background before they went to college in engineering.
This is a time when someone took Munro’s advise and pushed it so far that even Munro is feeling the shock
Shoutout to Cory looking FIT! Also thank you as always gentlemen for your hard work!
Thanks Farzad! Cory is down 40lbs.
@@MunroLive The key is reducing refined carbohydrate intake.
@@MunroLive good for him! Nebraska might need his help this year to get to 12-0.
Sandy's fat jokes finally got to him. :(
He's reduced his consumption of threaded fatteners 😅
Liquid Nitrogen is -196C. 80 degrees higher than absolute zero. And ... atoms don't "fall apart" if they get too cold. I know chilling the packs for grinding is a useful tactic; but that hurt to hear.
I cringed a bit. also, don't they have an FTIR for plastic ID??
Maybe discharge to zero and grind them down in a normal crusher plant?
Cooling it down makes I brittle therefore better for grinding to a powder.
Surprised at this knowledge gap. Very cringy indeed.
@@RotorWorks Batteries coming in for recycling stand a good chance of being damaged, so discharging might not be possible. Freezing does greatly limit the potential discharge rate, so avoids the thermal event with visual indications.
Bloody fascinating!! Thank you for sharing the knowledge, you are an awesome group of experts and your videos are groundbreaking!
You guys are awesome! Its amazing to see the 4680 pack like that. Cant wait for more MUNRO LIVE!
Hahaha the total miss of Talladega Knights reference is peak Sandy. Don't ever start feeling lucky btw Sandy, glad you guys always play it safe!
Nights
Actually Knights makes more sense with that movie honestly
You’ve now made me want a medieval version of Talladega Nights but instead of NASCAR it’s jousting.
@@snazzy Alabama Jousting with a gay Frenchman 🤣
@@KCJbomberFTW oh my goodness, no kidding you have informed me that it's Nights lol and yeah! That's exactly why I thought it was Knights, two courageous Knights lol
Thanks for addressing recycling!
I like the liquid nitrogen hypothesis. It seems to conform to Elon's approach for simplicity.
th-cam.com/video/_Chif5XdNlc/w-d-xo.html
Excellent !!! I really enjoy the way that you all tell us EVERYTHING, not just the recap. Keep it up. Super product that you're producing !!!
Its good to see Cory growing into his own and taking the lead more and more, especially highlighted when Sandy was away and he was the main driver of these video reports.
Side note: The structural pack sure is intense.
And now he’s Chief Engineer at Lucid
Thanks for explaining how recycling works. A bunch of “engineers” in the comments thought you pick apart the battery piece by piece. It’s much easier than that.
Those engineers work for the railroad.
It's still a reduction in recycling, there are a lot of people that want to reuse the cells (reduce, REUSE, recycle), when the car has 300k on it and the pack is at 60% capacity you want to reuse the cells, they would still be good for a while as grid/home energy storage. Essentially, this foam seems like it makes reuse of the cells impossible.
I was just about to thank them for doing this. I didnt know it was that easy to recycle. My first though When i saw All the pink stuff was also that it Will be a nightmare to recycle. I really learned something important here ☺️
@@edman007x
If you ever looked at the first patents for the structural pack you would already know the foam was going to be there.
This clearly eliminates the most important part: Repairing and Refurbishing and then Reusing in other applications and lastly comes Recycling.
And that bullshit about recycling with liquid nitrogen and all that, it does not work like that. It is not viable to do because of cost and complexity.
Sounds like Sandy needs a Talladega night! Movie night at Munro! Lol
Awesome, thanks for showing us what's going on in the battery pack. You guys rock!
Big thanks to the team at Munro for delivering these high quality and educational videos. I do not understand most of it but still find these comparisons incredibly fascinating
Woohoo, great job guys!
We all thank you!
Thank you for these informative tear down videos. Learn something new every time.
Glad you like them!
Another great video. I enjoy watching you and your team break things down and explain the working parts. Thank you, Glen.
Thanks Glen
Incredible work guys, despite the hard work sweat and tears this is a huge world first and you are uncovering all this engineering for amateurs and professionals alike
Another great episode of “Engineering Archeology”. Dig it.
Or "what the heck does that do?"
@@JBoy340a “it sucks in air”…..”that’s definitely suck’n
You guys are amazing. Thank you for all this information which you put out there, truly appreciate it.
Our pleasure!
Wonderful as always. Glad the cells are intact(payoff from lots of patience and persistence with lots of restraint. Kudos to the Munro team). Now Munro gets to baptize the term for bricking the unbrickable into the English vocabulary.
Suspect there are reserve cells and also
some kind of one time fuse technology to add them later. Seems like a good mitigation technique to address premature loss of capacity in the first generation 4680 cells.
Love the series , like the objective talk and love how your business is no pivoting to this vehicles and hope it’s thriving !
The “bee’s nest” looks like the collector output for the individual abs base caps for each of the cells. The gas from an over charged cell needs to go somewhere.
0:10 Blasted away with dry ice, like I suggested.👍 You're welcome.😁
Greetings from Stefan in Germany. 🇩🇪🤝🇺🇲
Thanks from the great video again! 👌
Thanks for the tip!
@@MunroLiveI can feel the hard "archealogical" work you are going through. I'm glad my tiny hint helped you a bit. Keep going Munro team! 👍👍
Thanks for answering the recycling question! Super fascinating
You should make a dedicated video explaining the recycling process. Would be great to have an easily shareable video to address the huge misconceptions going around. Sandy’s explanation was fantastic
How would they know? They are not recycling specialists. We have only the Elon's twit about it so far
Oh they just bury the pack in the ground that’s it
Here’s how VW does it.
th-cam.com/video/LABwwX960mk/w-d-xo.html
Shredder instead of grinder, no LN, cyclotron instead of floating separation the rest is the same.
@@Jushwa yeah let’s just burry a few grand worth of raw materials in the ground.
A small startup prototyped the liquid nitrogen system a few years ago. The temperature isn't dropped to make the materials shatter more easily ... it's dropped to stop or greatly reduce the chemical reaction rate, so that crushing and tearing apart the battery doesn't cause a thermal runaway from the residual charges.
Every 10 degrees C drop in temperature halves the chemical reaction rate.
So it simply won't be necessary to manually disassemble each pack and module bolt by bolt, the way some are doing right now.
Floatation cells have been used in the mills at base metal mines for probably a hundred years. Crushed ore goes in, high grade concentrate comes out. Chemicals in the slurry control how different materials float to the top in the floatation cells at each stage of the circuit, to separate different materials.
Thank you for sharing the insights you glean from your hard work with your audience for free!
LOL! Love the Rocky Bobby reference at the end!
Rocky Bobby? Is that the boxing brother of Ricky Bobby?
@@skipondowntheroad5833 LOL meant to type Ricky.
Another fantastic, and informative video! Thank you, guys!
So happy sandy explained the recycling process.
Great content guys. Appreciate you doing these tear downs, always learn something. What do I do with my hands!
Thanks for watching Beau!
Great job guys!
Munro rock, no one ever could imagination what is inside without You guys, Big thanks for sharing !
I really do love this gentleman's explanation on how to recycle this battery once its dead, learn something new everyday. Thumbs up!!
It's really interesting to see how they put it together!
Can you guys at Munro find the vendor for the foam and ask what their take on this is? I'm guessing they have a specialty solvent that will ignore the other plastics. Reuse > Recycle > Waste
Or you just use the whole damned thing and plug it into a new battery storage system.
@@Barskor1 yep, after a car then it's house storage, milk whatever is left that way. Only need to grind it up when it's totally gone.
@@stevenson720 No. It is into the grinder for recycling. Recycling the minerals reduces the cost of new packs. "reuse" in the slogan "reduce, reuse, and recycle" is there just because most things cannot be recycled to make it seem like you are helping when you aren't. The low volume of people reusing EV packs is absolutely meaningless. Recycling 100% of packs is the real deal. This is what we need to close the loop. Once peak minerals are reached in the recycling loop, new mining is greatly reduced. Reuse for silly one off projects prevents recycling. Tesla will eventually hit people with a massive core charge if they keep their old packs because recycling is necessary to keep costs down and reduce pollution.
@@stevenson720 Indeed simple and practical.
@@_PatrickO That is end-of-life processing till then there is plenty of capacity in a EV battery.
Cool walk through once again. Thanks guys!!
Thanks gentlemen- fabulous stuff, as usual!
This is an early structural pack, the four modules have been shown in the Tesla promo videos so no surprise there. Tesla said that this is essentially a generation-1 pack that just gets the job done. There is a ton of space for the product to evolve; and evolve it will. I look forward to the pack teardown in a year and two. :)
TESLA innovates at LIGHTSPEED.
@@markplott4820 how many fanboys here ...
@@WarezCommentary Regardless of fanboy status, it's the objective truth. Every other manufacturer is still using pouch cells 😂
The incremental teardown over the last few weeks is suspense intense. I'm loving and hate the pace here lol
Thanks guys! Keeping tearing this puppy apart!!! Love your videos!
Great content as usual, Sandy and team. Can’t wait to know more.
You guys rock hard. Keep picking at the pack and sharing.
Yes I'm rock hard from this.
Have you tested the thermal dissipation qualities of the pink foam?
Thank all of you for that report (so far). I never expected my assumption of recycling strategy to be even nearly correct. Back to the show!
Great report! Seeing vehicles being dissembled is very educational, especially the electric genre!
Shake and Bake!!! Great work @Munrolive keep the videos coming... As a MYP owner, my only gripe besides QC and Service is the amount of plastics in the interior. I get that threaded fasteners should be eliminated when possible but I've had quite a few plastic fasteners break with normal usage. I can't imagine long term durability. Car is a joy to own though and on the plus side the plastic parts are easy to replace. No car is perfect and I'm sure durability will continue to increase as more data comes in.
Apparently , TESLA is Launching F1 race style Service PITTS .
to shorten wait times.
thank you for addressing the recycling concerns! I found it very annoying how much people were confusing service-ability with recycling-ability. Keep up the fascinating work!
It's still a concern because it's Reduce> Reuse > Recycle and Tesla is straight up deleting the Reuse possibility, you can't scavenge good modules to put in another car that needs it, if a few cells fail this whole thing needs to be replaced for a stupid amount of money.
@@TheFPSPower the whole point of having so many cells is that some can fail while the rest of the pack can carry on. by the time the battery pack is unfit for use, there is nothing of interest that can be reused, and the sheer amount of nickel within these packs means that it is more productive to recycle than reuse.
keep in mind, it takes some seriously good engineering to design something that is used so thoroughly that by the time it is at the end of its lifespan, there is nothing to reuse.
@@TheFPSPower yeah only exchanging one module in a Tesla battery isn’t a viable solution anyway as the BMS is unable to balance new and old leading to another module biting the dust quickly.
And it can still be used in stationary energy storage if the pack works.
Ace presentation, makes me smile and interested further. Great work!
Fabulous inervies Sandy and Cory. Can't wait for your next episode.
I am sure Tesla Engineers are watching this and having a very satisfying chuckle as the the pride wells up in them for having stumped Sandy and co.
Cory, Sandy and team Great video. Interesting comment from Sandy, 'Telsa does not have a limit on their capacity to invent' This permanent foam approach, a person can never do maintenance on this type of battery pack, means Telsa has lots of faith it will have extremely low failure rate.
Not to mention (to all the "but service" commenters) but if it's under warranty and fails, you get a complete new pack, *WINNER*
If it hasn't failed by then, it's likely to last much longer.
It also means ultium is a joke. It is designed for serviceability because GM has zero faith in their batteries. The companies that cut corners to reduce warranty risks will have less efficient cars that cannot compete. Tesla can probably recycle an entire pack to base minerals for less cost than a single in warranty cell replacement on an ultium pack.
@@rogerstarkey5390 yeah, this makes sense. Also, if you remember from the earlier videos from when they dropped the structural pack, it was among the simplest to remove from the rest of the car Munroe has torn down, iirc anyway. Meaning that once these are manufactured at scale, this is going to be a relatively simple procedure, decades from now when you finally do want to replace your battery because the rest of your car held up for 400K miles. And it will probably be cheaper and more energy dense by then as well.
Capacity to correct their errors and restart the learning curve for manufacturing.
@@rogerstarkey5390 What do you say to people buying a used vehicle outside of warranty? Too bad, go buy a new battery?
HAHAHA The Ricky Bobby reference at the end and Sandy's reaction were gold. Great video, super excited for the future of this teardown!
We share your excitement of discovery and I look forward to every one of these videos.
Thanks for these tear downs. Always fascinating seeing things that the normal folks never would see. The engineering involved is 🤯!
Looks like the 800 dollar price tag for one cell might turn into a money losing proposition for Munro! This pack is going to take hundreds of hours to take apart.
1 Cell maybe 10$
Great reveal!! It will be interesting to see how other manufacturers make their battery packs.
Thanks!
Flat wire is sometimes used to reduce inductance. Not sure if it applies here.
It's also often used for high current connections by ultrasonic wedge bonding.
I wouldn't expect inductance to be an issue for DC, but perhaps the inverter draws current from the battery pack in high frequency pulses. I would think that a flat wire also has superior heatsinking potential.
@@mattgraham4340
They are fusable links and flat ribbon wire is used rather than traditional round wire since it provides a better wire to substrate bond. The flat wide surface of the wire works well with the wedge tool bonding 'head'.
Another example, internal welder connections. I would guess also easy to spot weld flat wire. Looks like from what can be seen none of the battery cases are inverted as a way to series the 4680 voltages. Excited to see when they get the rest of the top cover off as to how everything is connected
@@danlewis243 The batteries have positive and negative on one end, so no need to invert any. This is fairly common in the industry for exactly that reason. The entire bottom, sides, and part of the top are all anode.
Great work guys!
Thanks, Martin!
Thanks Sandy and Cory for this battery pack update. Looking forward to the next video.
More to come!
Thanks guys 👍👏
Sandy & Cory at the Tesla event you could see the exploded version of the battery pack with the inter cell side cooling channels. At such bigger volume for individual cells, it makes sense to cool the biggest surface and that is the side of it for sure. I bet the foam is thermal insulator, sound proofing against the road noise, structural rigidity improvement and fire retardant. It is a genius design and amassing innovation of what a structural battery pack, never attempted before, should be.
Yep. But there were many people who doubted that would actually go into the product. Bottom plate cooling was reiterated again and again by just about every Tesla channel after Battery Day so that it became the common consensus. Interesting, Lucid IS doing it, but Tesla isnt.
It'll be very interesting to see how the cooling channels are arranged and why Tesla is sticking with side-cooling. Cylindrical don't heat up evenly--they generate heat from the inside out, bottom to top, which is why pack designs like Lucid's, use end-cooling. Tesla might be using side-cooling due to manufacturing considerations or due to them building one big battery pack rather than a series of modules inside a pack
You mean a battery pack that is essentially just something to throw away after the use in the car right!? Because there is absolutely no way that thing can be reused for other applications after the car life! That’s a disaster
@@carholic-sz3qv Yes it absolutely can and will. Stable storage is a MUCH more pressing demand than overpriced conversions.
Thanks for describing the simplicity of the recycling process, and the big lump of nearly pure ore that constitutes the battery.
This is all very interesting. Its amazing what Tesla is doing. And to think its all completely recyclable. Very cool. Thank you.

WhooooHooooo! Going for 600K soooooooooooon!
The foam part reminds me of boator surfboard composite construction techniques.
First of all, great video breaking apart the different components! One thing I am wondering is the composition of the pinkish foam. Is it fire proof? How it’s helping cooling the battery? It must be some kind of high efficiency thermal-conducting material right?
YES, fire retardent foam , extingushes fire , creates protective barrier so adjacent cells dont catch fire also acts as a Insualtor .
does not help cool the battery , acts as Insulation , like a ice chest.
the Active cooling come from the Ribbons filled w/ non flamable Coolant.
I love what you do. Thanks for sharing.
Great insights. Thanks a lot!!!
Finally another episode on the 4680! Keep it up!
Edit: I am wrong below. It will 828 cells, unless they do something different on other packs. The next row will be 35 cells, and it will alternate between 34 and 35 cells. This does mean that it will be a 92s9p config, which is also lower voltage than current 2170 builds. Not sure why they would do that.
"For the total number of cells, 816 makes more sense than 828. The pack is overall the number of cells in series multiplied by the number of cells in parallel. They have to both be whole numbers. Given that Tesla is still on a 400v architecture (between 350v and 450v max charge), you need around 100 cells in series to make that work. The only parallel numbers that work within that range are 8 and 9: 8 for 816 cells and 9 for 828 cells. 9 in parallel would mean 92 in series while 8 in parallel would mean 102 in series.
While both work for a 400v architecture, 9 would be a lower voltage of 386v. When it comes to charging, the super chargers are amp limited due to heat. This is also the case with the controllers and motors. But this would be an unnecessary limit to charging speeds. 8 would be 428v. This would allow faster charging speeds for the same amount of amps. It would also allow the motors and controllers to run cooler."
I came up with the same math. 204 per section. 4 sections. Each section is two series strings of 102 cells. So a total cell count of 816 is very plausible.
@@trent_carter Thank you. I hadn't thought about the individual sections. Makes sense though, as each module would be identical in that. However, it would make it impossible to reduce voltage by separating the modules from each other.
I kinda want to take a voltage meter to several connections. That would give series counts, which is the most important aspect when looking at total pack size. Dangerous if you screw up though. 100v DC is more dangerous than 100v AC, and we are looking at a max of 400v and enough amps to melt steel.
You have those combinations correct. The voltage difference between the two of them is unimportant; the Ford Mach-E standard and extended range batteries are 96S3P and 94S4P, with no change in the motors or controllers and no loss of performance.
The count will almost certainly be 828, if only because when divided into the four blocks (modules) the resulting 207 divides into whole groups of 9, while the 204 resulting from a total of 816 does not divide into whole groups of 8.
@@brianb-p6586 You are right on the voltage not being that important overall. While it is important, the motors and controllers have a wide range that is acceptable. Similar to the charging systems. It does need to stay within the acceptable range, but that's it. Otherwise, higher voltage is slightly better than lower voltage since it allows less amps for the same amount power. That reduces heat.
You are incorrect however with the pack groups. We can see that the first module, which has to be identical to the other side, is 204 cells (6 by 34). The center modules are also 6 across. The 828 cell count comes from someone saying that the center modules were 35 cells down and 6 across, while the sides were 34 by 6.
@@anthonypelchat No, as Sandy mentioned they don't know how many cells are in that block. The edge row has 34 cells, but when they did in far enough to see the next row (which likely has 35, and the they alternate like that), they'll actually know how many are in the block. No, the blocks are logically not different; unlike the original Model 3 2170-cell battery, the middle blocks (modules) do not appear to be longer.
Thanks for the Hard Work. Keep Posting Videos Like these. Love to hear it from the GOAT himself
Amazing work I just love everything the best keep up the amazing hard work
Guy's its always great to see you all digging into the weeds to figure this stuff out!! Love it and subscribed. Also shows how well designed the Tesla is compared to everyone else. You guys have taken apart the cars and now the batteries to show just how well designed these machines just are. Good luck everyone else. The media makes it sound so easy that others are going to be competing with Tesla. Yeah, they can have an electric car, but is it worth a sh!t?
I love Teslas, but don't discount the other guys. Loads of intelligent engineers working all over, all collectively learning from each others' designs and past failures.
Just hold off on the first or possibly second generation of anything.
Munro, always treasure trove of solid information! Who knew?-threaded fasteners?
the FUD Muck-e has brackets holding up more Brackets.
Muck-e is litterally SCREWED and HOSED.
SUPER COOL Video! THANK YOU SO MUCH!!! -FASCINATING!!!!
Thanks for the informative video.
I think that the thickness of the cans and the amount of adhesion was just a precaution for 4680. Once they are more confident I can see them optimizing the structure and gaining density.
Also they might be compensating for the material used for the canister. Using a different formula for the canister now that the batteries are structural might save money and weight. This is me just guessing, I’m not an expert by any stretch.
So exiting to see what you found
Great to see Sandy!
Really appreciate the the step by step break down of how you would recycle this battery pack.
I recall when working with LN2 in a lab in my youth we froze bananas, balloons and other foodstuffs and regularly played "catch" - oops, dropped it! - breaks into a thousand pieces. Great fun. (Not quite "molecules falling apart" as Sandy thinks though.) Notably, left to unfreeze, everything turns to a yucky mush, particularly bananas.
I think Sandy might be on the right track but also hope Tesla will have thought carefully about how they will make the recycle process work, "at the end of the day". That battery pack is clearly designed to deter anyone from being nosey too. Regarding Elon's comment (8:11) I have said for decades that folk should buy shares in landfill sites - there's a rich materials resource just waiting to be used.
Gold! gold! Such good info.
thanks Munro team!
with this amount of foam, this battery pack should insulate noise and vibration coming from underside something like rolls royce level.
But it's a small piece of floor only. And bolted to the chassis.
As a mechanical engineer and Tesla investor these videos are like Christmas for me. Keep up the great work guys!
As a Tesla fan and investor I can’t wait to see the technology that will come out with the Cybertruck which I’m a reservation holder. I’m hanging on Elon’s words indicating that it might just be Tesla’s best product.
Maybe you should sell your stock because this design sucks!
LOL, stop rubbing your dick mate.
Glad to hear about the recyclability of these packs and of course is essential for sustainability of the technology going forward into the new and strange modern world we live in
Cool video. Thanks for explaining the recycling process, really interesting 👌
You believe it?
Thanks for all your hard work, it is very educational.
That top layer of insulating material looks like G10 Glastic material. Used in electrical applications like switchgear and motors.
Looks more like natural nylon to me (no dye added). The dry ice blasting has given it a bit of a matt texture but still not as matt as g10. Also g10 is an order more expensive than nylon, it cant be injection moulded and has to be machined for shapes like the one we see, which would further increase the cost and slow down production (injection moulding=good for high volume production). Not to mention its weight penalty over nylon.
Great video, thank you!
Just received my Tesla 3 RWD . It’s a total thrill to drive. The acceleration is next to none. It feels amazing to be part of the transformation to clean and sustainable energy. Im as happy as a kid at Christmas 🎄
Where was the electricity which you use, generated? Most Tesla's drive on coal or nuclear energy...
With liquid nitrogen you can freeze stuff, but you will stay well above 0 Kelvin.
Yes, and all components are chemically deactivated.
Can't wait for the team to open up those individual cell to see the design behind the cell.
Yes, that!
Check out a teardown on The Limiting Factor, here on TH-cam.
I've never seen Munro open up any individual cell - that leave that to other companies.
Excellent show.
You're good Sandy !
Grandpa Canada.
Excellent presentation. Thanks.
I would much appreciate at the end we can conclude this investigation into mechanical thermal electrical schematic diagram.
Someone block 90 minutes on Sandy’s calendar for him to watch Talladega Nights lol
