The continuing teardown of the Model Y battery is amazing and appreciated.
Thanks, Jay! More to come!
Sandy called structural batt pack a "brick" since revealed.
I'm guessing it's structurally overkill based on what we see here, Elon said it was a C- iteration on an A fundamental design, bet they'll lighten it over couple yrs.

a question ❓
Who pay for these expensive experiments?
@ 3:14 Antonio's supressed giggle 🤣👏 He was about to burst. I bet, seeing Cory's serious face made it worse 😂
Great Team! Love the Nerd-Humor 👏
Thanks
I don’t get it. What’s the funny part?
Thanks for pointing that out. I got bogged down on 34/35.
69 - pure coincidence. Honestly.
"pink thumb of death" 😂😂

I can see "pink appendage/ substance of death" becoming a standard description?
Cory has slimmed down. Looking good.
Thanks Monte! Cory has lost 40lbs since 2021.
I'm appreciating Antonio's sense of humour. More Antonio please 🙂

Thanks Farzad!
Sandy Munro has assembled the most awesome set of engineers/analysts. Wall Street analysts should consult these guys to do their analysis. If they did, they wouldn’t recommend anything but TSLA.
Munro does not underestimate the Chinese, see the new Xpeng G9 announcement with 480 kW charging.
Can the 4680 do the same?
@@abraxastulammo9940 It might if Tesla only targeted cell life to be 100,000 miles instead of 1,000,000.
Lol….. what Wall Street!?
@@flipadavis are you sure about that!?
@@alanmay7929 Are you sure about the Xpeng cells lasting very long charging at 480 kWs? I will withhold judgement one way or another until we see real customers prove that these charging speeds are possible and repeatable without drastically shortening the cells' lifespans.
@8:00 Cory is Hulking-Out over there; it is a good thing that he wasn't angry or turning green too~
Everyone there does a phenomenal job explaining the ins and outs of all that engineering. I am learning a lot from you guys. Thank you and keep up the great work! Also, subbed.
Every time I watch one of these structural battery pack videos I have to think that there are a bunch of Tesla pack designers laughing at how it's kicking your butts. No disrespect because we know the quality talent at Munro, and we enjoy the amazing insights.
*Tesla's new battery structure is nearly impossible to take apart.*
*Cory: Hold My Beer!*
Now tesla is doing the same thing which almost every American company does.
Hold with glow say no to screw.
I think some engineers from apple has been found place in battery department which is knew for Tesla.
@@akhtarmohammad6205 *What Tesla does is seriously for safety reasons(Apple does it so you can't fix your iPhone, Laptop, etc... yourself). Should you get in a serious car crash, which happens multiple times every day somewhere on this earth, you won't end up getting burned alive.*
Wow, that pack is going to fight you guys for Every Last Cell. Beefy Beefy Beefy!! Nice to have that structure protecting you during a crash...
What’s better than watching à Munro video at home? Watching one on the beach in the Caribbean 🇩🇴
☹️
Having said that, right now it's 30°C at 17:15 in London 😉.... Could be worse.
Cory, congratulations!!!! I just went back and watched the video from giga Berlin, what a change.. please maintain the change, I am decades old than you and the older you get the harder, harder the weight is to remove. I have been in a battle for the last few years and life happens often and makes it very difficult to loose the weight. Thanks for the wonderful content.
Great sound & camera work as always! That looks like beast to tear down!
Cheers for tirelessly putting quality content out there! Extremely informative and educational, all this stuff!
Great work everyone!
Cool job guys, I know it hasn't been easy tearing apart the battery pack
Love the continued efforts on this pack! Weaker men would have thrown in the towel by now
💪💪
@@MunroLive You should measure the capacity of a single cell (and other parameters), this information is waiting for a lot of people.

Should have dyed Cory green(😉)
I may not use any of these information in my entire life but knowing about new things is very exciting. Thanks to amazing Munro team. 👍
the rigidity of this foam is amazing.
The work that goes into one of these battery packs is mind boggling.
Amazing that there is no shear connection (no glue / foam) at the bottom of the cells… So actually the structural pack is not a sandwich structure - rather a battery - red foam plank….
Thanks for these amazing videos…. Good job!!!!
Thanks Cory. Great to meet you at the takeover last week. Keep up the great work.
Awesome video guys.
Thank you, A wonderful video. What muscles!!!! Lol. Thanks again for your hard work.
Thanks for watching, Ron!
You got this apart with way less damage to everything than I expected. Good job, Munro team!

And we have to chuckle 🤭 at Cory’s reaction to the cell count…KEEP UP THE GREAT JOB 💚💚💚
Elon: Lets make the first 5k packs very difficult for those who what to open our new pack.
Engineer: How much of the pink stuff do you want to use?
Elon: YES!
You have 20% likes on your views. That has to be the highest like rate on YT.
Wow! Fantastic information!
Love to work you do MUNRO! This just make me think of what the cybertruck tear down might be like 😳
At this point, it will look like CGI.
I'd buy another Sandy signed sticker to support that!
@@davidbrayshaw3529 why do you say that? The gigapress is in place for it right now and the production line and 4680 line are being dialed in as well. Next summer they roll of the line and SEMI rolls off the line this year.
@@GET2222 We'll see, wont we. And we'll also see how that promised $60,000 price tag looks too.
Electrified Garage: "We can repair your battery pack when a cell dies."
Tesla: "Hold my beer!"
Hopefully 5x less cells translates to at least 5x less chances of something going wrong with the pack.
@@jrharbortproductions If a cell goes bad, at least it still contributes to the structural integrity. :)
Nah, Rich's knife will go right through that pink stuff.
@@Resist4 how does that make it any better
@@jrharbortproductions
Hopefully, but not necessarily.
Love the work guys keep it up.
Thanks! Will do!
LOL that end scene!
Wow those batteries are seriously glued gezz...
Cory is a beast, you can do it just a few hundred more to crack!
That pack is giving these tear-down experts a run for their money
@@lemongavine Yea for sure no way to repair it at all just goes to the meat grinder for scrap!
@@TeslaRebuilders recyclable from what I’ve heard.
Definitely a game changer when they can get the 4680s fully ramped! I can't wait to see them come out of a Cybertruck and Semi.
I'm getting excited to see that too, less than a year away!
they’re switching to BYD blade batteries at gigafactory berlin for the model y.
@@kam_iko and they are building the battery building on the GigaBerlin site as well. 4680s will be present in some way at Berlin in the future.
@@kam_iko that's kinda a side topic...maybe you meant to reply to someone else?
@@kam_iko Those are LFP batteries for shorter range models. Good cells of course. But LFP is heavier and takes up more space than NCA/NMC cells, which is the base chemistry for 4680s. Longer range models are likely to continue using that chemistry, and the semi cannot use it due to weight restrictions.
That said, LFP chemistries are improving very quickly. We may see long range Model 3 and Y using them at some point.
What I love so much about Munro's TH-cam videos is that every second is well worth it. "My beautiful ApPlE watch" lol.
The pink foam of death is pretty cool 😎
You must be worthy to lift a bandolier of 4680s! Great job working through this 👍
Would love for you guys to address why solvents that normally work to dissolve foam can't be used for this purpose.
I started to try to answer you because I know some chemistry...
Then realized I don't want to type that long for what's kind of a poor question.
So I deleted it all and suggest you start learning chemistry
@@bobjoatmon1993 why bother leaving a comment at all? Good question, stupid answer.
@@bobjoatmon1993 Weird, I don't recall asking if sad douchebags who don't work for Munro could comment about how smart they think they are in the most "I live in my mom's basement" way possible. But here you are..
When you're trying to break the structural packs in the end of the video it reminds me of the Napoleon Dynomite tupperware scene 🤣
Brilliant & Fun Review 👏
Cheers,

Thanks for watching, Eric!
Excellent video and thanks!
Glad you liked it!
We need the guy who designed this structural battery pack to clarify why/what/how of each components. Even the Munro team is struggling.
Maybe they don't know either.
Amazing work! 👍
Thanks a lot!
Thanks fellas!
A fine job guys. Really. Fantastic work guys, keep sharing those tear downs. Absolute amazing to be able to follow along.
Do you think this pack design will be kept? What surprised me was to see the pack had the traditional side cooling line. After battery day, I feel consensus was for the 4680 cells to be cooled via the bottom, as that apparently is the more efficient way?
What about weight of the battery pack? When unbolted what did the pack weigh in at? And how is that compared to other Tesla packs?
If it's any indication, the Made In Texas Model Y weighs about 20 pounds lighter than the Made In Fremont models. The weight savings likely come from a combination of battery design changes and the gigacasting. My guess as to why Tesla designed the battery pack this way, is that it makes them quicker to assemble
@@areitu I read the opposite. And that's with the lower kwh rating.
You should do a flame test on that pink material. It would be interesting to know if it has flame retardant ability in addition to its structural strength.
Elon once mentioned something like 'fill the gaps, or glue it together, with fire-retardant epoxy' so I would be disappointed if it wasn't!
They've taken outside and hit it with a lighter in an earlier video
Edit-I went back to the rivian pack video and it appears the foam from the Tesla was blue. So I guess it was a different version of a Tesla pack
They said they would in comments on either previous video or one before that.
That is some real structure in that pack.
Kudos to your head of sound effect engineering! The last sequence made me laugh out loud!
I hope they get hold of a berlin tesla and take apart the structural blade LFP battery pack
Shipping to US may be legally impossible.
@@EMichaelBall maybe as air freight but they can ship cars by boat
@@Werdna12345 (it is only air freight in passenger airplanes which is a problem, dedicated freighters can ship bulk lithium batteries.) - If a product for some reason can't be imported into the USA - ie. the 25 year DOT compliance rule - just reclassify as for off-road use only, or "industrial spare parts" - in pieces... OR do a teardown in Europe, I am sure European manufacturers will (be happy to) check on the competition as usual.
Will there be a breakdown of the individual cell performance ?
Give a few to Jordan G.!
Fascinating
very interesting info about the structure of the battery moduals..
This battery pack is strong as a bull. And Munro is milking it for all its got. 😜 thanks for the in depth videos.
Thanks for watching!
Did you say Sandy is milking a bull? 🤣
The extra scene
"Strong as bull"
"Mongo live"
(Blazing Saddles ref)
@@rogerstarkey5390 I know the reference sir. "Mongo just pawn in game of life."
WOW! This project almost broke the Munro team and that's saying something. I think some of the SpaceX engineers worked on this pack for sure. The report on this is going to be worth a lot of money but WHO could even begin to copy this and they are still looking for ways to IMPROVE. Incredible.
Do you really honestly think a throwaway, unrepairable piece of crap is a good thing? Note: Recycling the pack doesn't help the customer pay the $10,000 bill.
@@DavidJohnson-tv2nn we will see in future how it plays out for Tesla. They always try new stuff out and test it and maybe if the battery is reliable enough then this will probably be the way to go
There is nothing spacex here stop the crap!!! You can clearly see the glue must be some sort of epoxy/automotive glue nothing special
@@DavidJohnson-tv2nn the battery should be made so that after the car life it’s removed and used as energy storage u too the capacity isn’t good and finally comes the actual recycling! Recycling is also very bad in the environment so the less we recycle/most we reuse the better it is.
@@Tom-ku8bu yeah bury all BMS, piping…… and glue everything in one pack for what!? Imagine if old cars were made this way!? There are litteraly 40 years old Mercedes’ cars still used as taxi in Morocco, even Mercedes trucks over 45 years old are still on the roads somewhere around the world.
Sandy's new Autoline interview was great.
Pretty awesome, thanks 👍
No problem 👍
"69 Cells in a bandolier"🤣
Ohh, 69 cells in a bandolier.
Great work thanks. Are you certain the pack warranty is still valid? 😂
Great video!
Thanks
Love your videos!!
Thank you!!
The bottom sheet metal is probably just as structural as the top sheet, but does not need to be glued because it has only stretching load. It has no reason to buckle.
The pack's strength would greatly increase if the bottom was glued, too (sandwich structure). But as you say, it can't buckle, and also they need a side to vent the batteries. It makes sense to choose the bottom for this purpose. At this point, the lower sheet metal cover carries some load through the sides of the pack and is protective against rare impacts from below. The top carries much more loads from the seats and the passengers. Good design.
@@gehtdichnixan4704 I think it would not be stronger if the bottom part would be glues in this application.
A sandwich structure is stiff against bending in both directions, but here we need only one direction because we know that our load is pressing down. A sandwich has two sheets that are strong against tension and against compression, but very weak against bending. We keep them from bending by putting a spacer in between.
If you put a load on that sandwich, pressing down in the centre, it creates compression on the upper side and tension on the lower side. The tension also makes the lower sheet press against the spacer. There is nothing a glue could do in this situation. It is a sandwich structure that works only in one bending direction.
@@vsiegel There are minor/edge load cases where a true sandwich would be beneficial: shear and torsion. But I guess these are negligible for a car and one would just accept slightly reduced rigidity in these situations.
As for the sandwich in general: the outer sheets are only strong under compression if supported against buckling. But a one-sided spacer/stiffener suffices to this end, so again this battery pack is well designed.
🤣🤣 amazing 👍👏
Thanks, Bruce!
So essentially what we are saying and seeing... is the fact that this battery pack is easily recyclable and repairable.... Sweet!!!
These Munro thumbnails are getting 🔥
This pack is the epitome of the old saying “No user serviceable parts inside” I’m pretty sure Elon did this with Rich Rebuilds in mind!
-Rich: "They always trying to keep a brother down"
-Elon: " I'm actually more African then you"
Ehhh. It's a structural part and literally just a huge battery. Batteries are never meant to be taken apart and structural parts need to be as rigid as possible.
Plus, every story I've seen of someone trying to replace a few cells in a Tesla ended with issues anyways. So nothing lost anyways.
@@BSEUNHIR
The last generation model S had modules that could be replaced. Ask Rich Rebuilds!
Great job gentlemen. THANKS4GIVING
The Mica is a mineral that has always fascinated me. It is found all over California, I used to find and make jewelry out of it. Mica long ago was used in many products, first on boilers & stoves as windows to see if Pilot Lights were fluorescing. Then the electric industry used it in tubes prior to chips being invented, then the chip industry used it as well, and now Tesla. It great to see old technologies utilized it shows me that Tesla is turning over every stone to accomplish the mission.
What do you think the purpose of Mica is in this application?
@jimb50plus - insulation ~2000V / mm. also thermally conductive, hmmm.
It’s not just tesla that uses mica lol…….
Love these videos, i get a lot of push back from the ICE crowd, i've been able to debunk so many mistruths about EVs just from the education i've received from the Munro team.
Thanks!
Thank you!
Great job. This battery is really revolutionary!
The cell AND the pack (2 separate things!)
There is absolutely nothing revolutionary about that! It’s just a bunch of glued all together batteries cells that are impossible to repair/reuse
@@alanmay7929 LOL all that explanation and there is the people like you who just go back to square 1 :D
@@DaveBoxBG and you go back to square root lol 😂 😆 😝 😂
@@alanmay7929 jokes on you since like your last comment this does not mean anything and exposes how little if anything you understand ...
Excellent show as always. Couple of questions , first what happens when few cells deteriorate or die? from the designs seems that the whole battery pack needs to replaced as one unit. Very expensive warranty or after warranty repair. Second at the end of the life cycle, seems to me that this pack very difficult to recycle or reuse components out of it. Hence more environmental impact
Was covered in an earlier video that the whole battery pack could be ground up into dust and recycled.
This is why the 4680 cell design development has taken so long.
Cell balance is (obviously) critical to lifetime. The BMS has a serious job to do!
Man this thing has to have a very high level of durability and quality, the cells, cooling channels and bms, its pretty exotic but entirely unserviceable.
And a 'challenging' recycling prospect.
Yeah, one tiny problem and it all gets "recycled"
@@MrCarGuy
At probably double the original manufacturing cost
It's a rubbish design, Built in obsolescence at it's finest.
@@andrewholdaway813 do you even watch previous videos?
Recycling it is easy🤣
"Oh, 69 cells in the bandolier. Thats really interesting." Cory said it so matter-of-factly. hahaha
Cool and funny finale!
Thank you guys so much for sharing this awesome information.
Looking at the construction of the battery module and your disassembly i have to wonder if there is any part of the battery module that can be repaired or swapped out, or is it basically a full swap of the module if anything goes wrong with a few 4680 cells, for example.
Amazing!! guys!! So do we know now what is this pink stuff is made off?
don't think they have said yet. my best guess is cotton candy mixed with tears of elons haters 😉
Yes, we do.
@@jackgreenstalk777 love that
@@MunroLive Great!! love to see that in future episode! I heard you call it foam so it's sound like a light weight but how it was so strong! that's what I'm curious~
@@jackgreenstalk777 And shredded Tesla Shorts provide a fibrous mesh for extra rigidity.
Have you been able to do charge cycles with the new cells? What kind of energy density do the 4680 cells actually hold? 15 000 mah per single cell? Or higher?
They haven't even extracted them out of the box yet 😄😄
@@hammerheadcorvette4 Not all no, but some of the cells are out. You only need one cell to test it's capacity.
lol at apple watch haha thank you cory :) Always so educational and fun :)
Pretty smart to not have the batteries stuck to the lower plate, this gives a bit more clearance in case of a puncture on the bottom
Can’t wait to see how tesla continues to improve on this concept in the coming years.
Yeah copying apple and making cars less and less repairable right!? What a nonsense concept!!
When you look at those super old caterpillar ir vehicles in the roads imagine if those were made from a single large part!!
@@alanmay7929 would you like to replace single cells?
@@robindehood207 not a single minute multiple in case this fails instead of buying a whole new battery pack! With all the BMS glued into the pack goes knows how long those things will last lol…..
@@alanmay7929 how you plan to balance the pack after replacing degraded cells with full capacity cells?
How you going to control the voltage differences these cells newer cells generate?
How you going to get a single cells out without damaging the modules / coolent lines / cells near it?
How you going to certify the pack is safe and stable?
You going to pay the customer a full new pack if you brick/damage the pack?
You going to give warranty after the repair? Since why else would I even care to let you repair it if you could make the pack unstable and burn down my car.
It is way cheaper to shred the pack than to try to repair it. If repairing a cell was cheaper, they would already do it in hybrid cars and phones. But since the operator cost is so high for a repair no one things about trying to repair it. Not to talk about certification cost / schooling cost / tools cost / work hours cost since it need to be done by a specialist / part cost safety hazard regulation etc. The pack probably cost Tesla like 12k USD, so it prob will cost 15k to the end user. If you think that replacing a single cell is going to be as cheap as replacing an engine(which easily can go above 7k USD without parts, just work hours) you free to open a shop and prove it.
Tesla's next iteration - attach the suspension directly to the battery pack
They better add an adaptive suspension first.
Cast the wheel directly into the suspension and square wheel lol…..
Cast also the transmission, suspension, seat skeleton, why not 90% of the car? A young driver makes a mistake in the parking, you have total damage. That is the direction they are on, I hate how the pack is a $10k zero serviceability piece.
@@FlorinArjocu Battery pack failure will be an expensive out of warranty repair now. But in 5-10 yrs it will be as expensive as an engine or transmission replacement with the potential to last longer with some degradation of course. Battery packs will continue to go up in efficiency, down in size, and definitely down in price. Everyone is now focus on beating Tesla so competition will force EVs to keep getting better. This is only the beginning.
@@Teddy_M85 An engine is not a single piece. You only change what is needed.
