your shredder comment actually matches pretty close to what red-wood would do to process this pack. They would discharge it so it is no harm of fire and send it on through the process. There recovering 90-95% of the cell material.
@@peterjohnson8106 exactly. I can't wait for someone to finally get a boots on the ground process video with JB @ Redwood to show the world this.. People need the proof in video and content on it and let it be history after.
@@peterjohnson8106 That is an expense. Recycling grinders start big and get smaller as the material goes down the line to go from giant pack to dust in a series of steps instead of a single step. The foam would not need to be removed before grinding, but there is nothing that rules out tesla having a solvent for the foam that would let them remove the foam. If there are ports or holes that can be used to inject fluid into the foam, then these packs may actually be serviceable if you really wanted to do it. I have to imagine they do have a solvent extraction method to at least aid in pack testing and examination.
@@519Kustomz 100% it’s crazy how much material science has blown ahead in just 10 years let alone last 20. It’s crazy. Way smarter people than I could ever be, even with Wikipedia 😂
Thanks for that video! Super cool! I hadn't really thought of the changes the structural battery bank had to be and I wondered how the batteries hooked up because in all the pictures from Tesla it looked like they were just free floating in there which didn't make any sense. It would be awesome to see the whole pack before it got gouped.
Take a look at the pack from Vinfast (Vietnamese EV) . I believe they use a pre-moulded foam sheet with interference fit holes and press the cells in. Probably faster, neater and reversible?
That is the structural battery from Tesla. It's a load bearing part of the car. Seats are bolted onto it before it's placed in the car to speed up the production. I do not think the pack from Vinfast is structural.
Makes you wonder if this was done intentionally to avoid cell pack level of repair complaints, so if there is an issue they can say you "have to" replace the entire pack...
@@519Kustomz Why is the penthouse covered in that foam? Seems like only the cell portion would need to be structural, that would have allowed for repairs if any of the control electronics went bad.
Hi. Good job) What was actual weight difference of 4680 and 2170 battery and if you know. Or maybe you can say the weigt of the vehicle on the vin lable. Thanks
Question, could Tesla squeeze more cells on the sides? Looks like some room from the black foam (possibly for crash), but is there any room outside the pack to move that farther out to get IDK an extra 4 to 6 rows? 6/24= ~25% more range.
There is a bit of room but it would mess up the cell structure a bit. Outside packs could be something like 10 parallel but insides would still be 9p. Rumour has it that the chemistry is different on next years 4680 for energy density improvements. I think 8-10% better than it is currently.
@@519Kustomz The 4680 (as tested) actually had a downgraded anode (less silicon). It's likely that the first step when they ramp will be to run the 2170 anode material and the dry process Cathode, both of which will boost performance, with much more to come after that. They won't go for range (same quantity of cells) they'll go for a lighter pack with fewer cells that probably have better charge rate, any range gain will be weight related. . Their mission is to produce more vehicles.
@@519Kustomz I think it's more for structure and insult. You'll notice a weak spot in what would be the bottom of the cell. It's designed to fail and project any "energy discharge" straight through the bottom of the pack. This prevents heat build up adjacent cells, so no runaway "pack fire"
Thx for the video. Is there something like a double sided adhesive transparent tape that holds the FR4/glass fiber plate to the battery cell interconnections? Looks like that in the video, just need confirmation. How hard was it to remove that top plate from the cells?
That transparent layer between the fiber plate and cell collectors looked like it isolated the main cell collectors from the bms layer. It did not appear to have an adhesive layer to it but it was mostly destroyed removing the fiber plate. So the layers went - top of the battery cells, cut out thin fiber isolating sheet, cell collectors, transparent sheet, bms circuit, thick fiber plate. Every positive battery terminal had a grey adhesive to further isolate and adhere the layers together before the entire thing was filled with the pink foam. The top plate was very hard to remove and ended up coming out in pieces because the pink foam is so bloody good!
so if you get the volts right...why not replace the batteries of an old hybrid car with 4680 cells? should increse the range of the car quite good! or will the computers detect that something is wrong?

Wholly Hell you got a 4680 and ripped it open... Epic!
I'll support ya and buy a clean 4680 as I already have a 2170 on my desk !
Awesome man! Appreciate it

Chill in liquid nitrogen to zero out the potential and then grind it up into a rich ore

Wow - did you see Munro lives battery tear down? They used dry ice blasting to get the foam off
Yeah i did watch that! There is no easy answer that is for sure.
Sandy Munro had a hard time too to pick the battery apart.
There could be process to bio dissolve the foam if know the right enzyme.
I would bet you are correct, I would just make 100% sure any liquid was non conductive

Nope, Unless you could fit the entire pack like we did with the galaxie.

TESLA IS THE NEW APLE MEANING THAT THAT SHIT IS GOING TO BE UNRIPAIREBLE EVER !
Thanks very good video and explanation.

A chemical solvent that will dissolve the pink stuff, exactly the same as gasoline dissolves a Styrofoam cup.
Munro tried the solvent.
It's nasty stuff.

I will check that out. We just got a Vinfast dealer locally so i'm curious to see some cars around

Yeah there is absolutely no repairing this pack! But, the trade off is it is very stiff to help with the structure of the car.
@@519Kustomz Why is the penthouse covered in that foam? Seems like only the cell portion would need to be structural, that would have allowed for repairs if any of the control electronics went bad.
Aside from the cells, the only other thing in the pink layer are some bms boards. I have the penthouse stuff one video back and it is all serviceable.
@@519Kustomz Yeah I guess they have the data and those boards don't fail.
@@boostav Definitely those boards a bit overengineered for said purpose.

It would be a solution, cost prohibitive maybe, but technically possible. BMS / charge issues if it is an older NiCad battery model
@@519Kustomz an other issue might be cooling? the motor and everything just needs the right voltage…

Black foam along the sides, is it soft or hard foam? Is there anywhere on it material designation?
no visible designation, it was a soft foam. Compressed relatively easily.
As you said it's impossible to repair single cells die to the pink layer, but could the whole cell pack replaced of a Tesla?
Should be possible. Remove the pack from the car like he did, and replace it with another.
@@MFoley-tv3zh ...sure, but at $20k for an old car?
Where does the liquid cooling float?🤔
how heavy is the pink foam of death ?
It is pretty light weight wise, but really dense.
4:15 You mean between the cells and the battery pack cover, correct?
Yes, Sorry.
Would you be willing to sell a piece of foam? Roughly the size of that piece you cut off.
Yes Absolutely. Email Dan@519Kustomz.com
