@@BillB33525 If you mean "no brainer over the 3", the assumption is that that the 3 has the same improvements you are seeing here. They are just looking at a early 3 vs a Y which could be considered a current 3. They both will continue having changes done to reduce costs and fix problems.
One of those "pens" is a telescopic torch pointer, he used it in the previous teardown episode, E33 around 9.20 you'll see him use it then put it back.
So there was a conspiracy theory the other day when “Andy “ came to blow out the weldings; that he looks suspiciously like Sandy and it’s all just you on your own and there is no company at all... Now the fact that you’re wearing “Andy”’s coat seems to pretty much confirm theory that Sandy is just an automotive Walter Mitty Tesla vivisectionist in his garage alone during the lockdown😂 Seriously Mr Munro, thanks for doing this, it’s really fascinating 👍
Do you guys also analyze vehicles which are sold in other regions? I'd be really curious about how the VW ID3 compares to Tesla's Model 3 once it goes on sale, that's why I'm asking.
@@MunroLive do you also try to reverse engineer and analyse the software part of the cars? Do you have skilled hackers or embedded software engineers for that in your team. I think this might become more and more important in the future.

I think the difference between the blue and green foam is that the blue one is painted and the green one is casted, take a look at the edges. That makes the blue one way faster to manufacture. Hope to hear your opinion Munro.
The blue stuff isn't actually foam like he says. It's gap filler that has a high thermal conductivity meant to help dissipate the heat from the batteries to the battery module housing. The blue one to me looks like BERGQUIST GAP FILLER TGF 3600. TGF 3600 gap filler is pretty common for batteries. The green color is just a different gap filler. Both should be a form of a liquid before it cures. I agree that the green one looks like it is casted around the edges. The green one most likely has a low viscosity which might be why they have to use a cast to keep it in place like a dam. TGF 3600 is think enough where that doesn't need to be done. The holes that he didn't understand are most likely for outgassing.
It's probably been asked many times before, but I'd love to see a quick non-destructive inspection of a recent model 3 to see whether some of the problems with early models have been fixed.
I wonder how much has changed in the Model 3!! You just said that as I was typing. I am sure many changes have been implemented. I am sure China has lots of innovation!! As well!!
So in-between the batteries are incased in foam with layors for cooling and stuff formed and fit ? Then all metal, aluminum covers going on top and bottoms of batteries glued or fitted with forms built in to the foam while keeping it lighter it is filled Indian and the foam becomes brackets not filled in areas to lock in places for metal connection then when recycling the battery would be easier just seperate foam from all other components and not only use the batteries but all other pieces of battery pack connectors to just would make it simple right ? What do you think would a formed battery,lighter battery and one that's Easter recycleable be better can it be done keeping it cool so no overheating ?
@@marctenhove874 Recycle is melting the pack to its constituent elements are reusing them. Its probably cheaper for rare earth metals to be recycled than mined.
Also note.. these battery packs are not a one life use. These packs are expected to have a second, and likely 3rd life.. spanning over 20 years of use.. potentially as long as 50 years of service, before needing to be recycled back to their base materials
So how does the battery cooling work? Water / coolant is passed through hollow fins that go all the way to the back end of the battery and back to the lower part? The cooling fins only "touch" one row of battery cells, but it appears that there is at least a second or even third row not directly touching the cooling fins, correct? Where does the hot water go out - the other end of the black plastic tube or at the other end of the battery?
Rolls Royce developed a plate heat exchanger that uses layers of dimpled sheet metal. It’s cheap to make but very efficient. I wonder if these packs use a long plate exchanger between rows of batteries.
Time lapse shows how active you are in your senior prime. As an oldie myself I am wondering which mode of self destruct is worse, being a plump diabetic or sipping a lot of Jim Beam. I took the first route, but I bet you are healthier. Love your knowledge of all things I am curious about.
Not every cost reduction is a good thing. Sometimes, overbuilding a thing compensate for what can happen after things have aged specially plastic parts. I’m a MB mechanic and I hate taking apart plastic parts after 3 years or 30,000 miles of use specially if they are part of cooling system. They loose elasticity and we usually replace them when those parts are in the way. Our usual complaint, “ What were the Engineers thinking when they are designing these?”
It would be interesting to see if there is any improvement to the chemistry that would increase its capacity. Any chance for a capacity test comparison for a bunch of batteries ?
It would be interesting to see the difference in terms of capacity/charge rate between the two cells, comparing the old 3 version to the Y. I understand that might not be possible given the 3 has been discharged for a while.
Current 2020 Model 3 vs. first Model 3 units comparison would be much more interresting ! Probably many or most of the changes they incorporated into the Model Y are already present in current Model 3s
Sandy. Love it. Tip your cashiers boys and girls. Commercial suggestion for you. Announce you’ll reveal the Oct oval W tear down 12 months after your report is on sale. Drives up the price, generates excitement, and keeps us fans onside. 😷
Any thoughts on how recyclable that pack design is? It doesn't look like it was designed with recyclability in mind at least. And any chance of getting hold of a few of those Model Y 2170 cells? We're quite keen to test them out in the lab as a benchmark, and to crack one open to see exactly what is inside.
Since Tesla will be recycling these batteries themselves, I'm sure they considered it in the design and have a process in mind for recycling. www.greencarreports.com/news/1122631_tesla-launches-battery-recycling-at-nevada-gigafactory
Any indications that these packs have been designed with recycling in mind? Musk has always said these cells could have a high level of reuse and recycling, but the way that’s put together looks like that would be difficult
Will it be easy to deconstruct these battery packs when they are no longer useful? Can these be easily recycled or will they end up as hazardous waste?
Munro legends! Thanks so much for the updates, very interesting break down so far. Did you see any changes on the Autopilot camera hardware? I was wondering if they would improve the night capabilities.
When I teach welding and strike the pure acetylene flame I say "the flame is useless but very photogenic. It draws photographers like moths to a flame." Does give the video a Red Green Show feel, LOL. Just need to see a roll of duct tape.
The holes are interesting. I thought the solid foam was there to reduce the propagation of what we euphemistically call a 'thermal event.' Sure would be nice to see some details of the BMS.
I suspect they will address design for disassembly/ shredding/ retrieval of materials at battery day. Perhaps even Redwood materials will make an appearance/
Informative video, its interesting to see the evolution of the Tesla battery. Provided there is no inovation or breaktroug in battery technology, they appear to have a solid design based on proven technology. It is also evident that the future recicle efforts will be prohibitivly expensive. 10-15 years from now we might have a battery disposition dilemma of sizable proportions. This of course applies to all EV's not just Tesla.
Seeing all the improvemonts from M3 to MY I'm wondering if Tesla is going to put these improvements into future model 3s as well or if M3 is going to stay the way it is. Great video and video-series btw, very interesting!!
One thing that came to mind... for a future vehicle to tear down, I would like to see a tear down of the Ford Mustang Mach E when it becomes available.
That's difficult to recycle or re-use once these batteries gets old or not good enough for a car. I'm thinking if Tesla could somehow make the pack more modular, sacrificing a bit in space and costs so that it will be easier to re-use them as batteries for home/appliances/projects.
Except that they were manufactured years apart. An analysis would show incremental changes/improvements. But thanks for your condescending reply though.
you're really driving me crazy by always switching between "tesla 3"/"tesla model 3" and "tesla Y"/"tesla model Y". Anyway, great work! Really love the videos about the progress.
lightdark00 - TThose pack are way cheaper to build, cimpared to the MS and MX ones. he cells might yet be recyclable by having some kind of solvent to remove the foam. Then they get acces to individual cells. Then they might have to test every individual cell, and select those for use in a refurbished replacement pack. Still saves money and ressources i guess. Especially in large quantities.
@@bonzo-er6ly I was making a point about the word usage. I was thinking about the average person that would want to recover the cells or replace one battery. Gasoline might be the cheapest solvent currently easily available, that might work.
Get the upcoming rav4 plugin hybrid. 39mi of electric range, e-awd, they claim instant torque like an EV, and it is fast at 5.2s 0-60. It will be a model y competitor and fill in the gap that the chevy volt used to fill.
@aurelio milaor cabal It isn't about that. It is about using electricity for around town driving and commuting, but not having to rely on chargers for travel. Fuel cells are a joke, this is the first plugin vehicle toyota is making that is appealing. Instant torque is important and makes the big difference. That means this car will handle and feel like an EV when driving it, even when burning gas.
Tesla seems to have been producing castings throughout the epidemic. If they have a stock pile will this allow them to have a high production rate or is this not the limiting factor (in normal times). Conversely how reliable are these devices could a failure sent production for a prolonged time?
I would like to know if Sandy has learned anything new while disassembling this vehicle. e.g., "I never thought of doing it that way," or "I wish I'd thought of that," or "I don't know anyone who's ever considered an idea like this." He's implied that may be the case on several occasions but has never outright chronicled where either the 3 or the Y have truly new ideas that even surprise him. .
Mixed feelings about this. :) My old company made (I think still makes?) the robots that test the bond wires between the cells and collector plates for all of Tesla's car and Tesla Energy packs. I was in the Gigafactory for a week as they were trying to ramp up Model 3 production a few years ago, and I won't forget that experience for a while. Seeing those huge modules get slung around by the robots was a trip.
The improvements of these videos has been noticed and much appreciated. Great content Sandy, we appreciate all the hard work.

He should have a pocket protector in the pocket for pen leaks...
No slide rule....

Given how difficult these are to disassemble, I wonder whether recycling will ever be economical or if they'll just end up in a landfill.
There will be some sort of chemical that can break down the bonding agent. Recycling isn't always simple. It's all down to time to material value.
I was also wondering this. How the hell can we disassemble these packs quickly to re-use the batteries?

So collector plate was glued in ?
Is a chemical analysis of the batteries and charge characteristics of the 3 vs the Y battery packs part of your plan?

Weight of the TMY battery module vs TM3 ?
Is it a High Thermal conductive compound?
Would be interesting to know if model 3 nowadays shares the same battery pack as the model y. I wouldnt be suprised if this was the case.

What's the life expectancy of those O-rings?
I would expect that the cell packs would be different since the mileage claims from your M3 were lower than todays
