I rebuild salvage Teslas in Ukraine. Great analysis guys. One thing that immediately stands out to me - by putting the onboard charger and DC/DC in the front of the pack, they have hugely improved the pack's crashworthiness. I've seen a lot of packs that, in a severe frontal impact, have intrusion/deformation into the front end of the pack (where 2 levels of modules are). This likely has caused the fires in some cases. This new design essentially gives a much larger front crumple zone before any impact could touch the cells, thus reducing the risk of fire in a front-end collision. Deformation would have to be almost to front of the driver's seat before the cells would be impacted. Yet another example of great, intelligent design and constant improvement!!!

I also noticed that. Great minds!

I was working on a mica thermal shield for another OEM's battery pack. Tesla's is a unique part that not many can make. The main benefits of Mica over Sabics's Stamax is melting temp and thermal conductivity. OEM's generally test for "thermal events" with a ~5min >900C test (depends on battery chemistry) and the "cold" side of the mica part needs to stay below ~150C. (My material passed with flying colors, but not for a good enough automotive price...couldn't dial it back before the OEM decided on another supplier) Stamax is a polypropylene which will melt at 166C regardless of it being flame retardant. Mica is non-flammable, only the thermoset binders will burn; this is this stuff they use to hold the individual mineral flakes together and hold the curved shapes. Since the part also needs to be quite thin, Mica is the primary choice... and probably laminated with some kind of ceramic/mineral wool.

The last full year of financials we have for VWAG shows them only netting $9.5B in profit. So, Tesla made 60% of the net profit on less than 10% of the sales volume. Clearly there is a lot more to it than the scale VWAG has (more like HAD, as ICE production decreases). Tesla is just an dramatically more efficient beast in every possible way. Also, pricing clout becomes somewhat irrelevant when one makes their parts in-house, rather than paying mark-ups to suppliers. I'm pretty certain Tesla spends less on the seats it makes than OEMs spend on the seats they buy from suppliers. Edit: It's also worth noting that Tesla's operating margin is literally DOUBLE what VWAG's is (15% vs. 7.5%), so all the numbers suggest the opposite of what you are claiming as far as costs are concerned.

Great teardown, this is the one I was most waiting for and why I contributed to the cause! The reason they used the 18650's is not because they are easier to cool - remember from battery day one feature of the 4680's is that they generate far less heat and therefore will require much less cooling. They are using the 18650's because they have cell supply. The version of the car they are selling is only one of the ones developed - they had/have a 4680 version with a structural pack as well (The Plaid+ used it.) By using the 18650's they can use the 4680's from Kato to ramp Austin first, then once Austin can produce 4680's the Kato production can be moved to supply a new 4680 based version of the S/X - perhaps as a Plaid+ or put them into Semi production ramp, or even into a roadster II. They eventually will release a new version of the S/X with the structural front casting integrated with a structural 4680 pack.

It remains to be seen whether the battery will be structural (the way Tesla sold it at their presentation), because, you know it's a 2 tone vehicle and those cell walls be rather thick. Of course, they could always do it just like, you know, every other manufacturer does it and makes the strong shell and then populate it with cells and call it a day. But no one would notice and would treat the 4680 as 'next level engineering'.

You might notice that all the fasteners are star drive and mostly the same size, something all manufacturers should do. The engines might still be using separate resovers but they are looking to integrate them into the main windings and magnets since it takes a little change in wiring and software and eliminates 3 stations on the line. The best part is no part.

Thanks. You did a lot of work. It was nice of you to share it. And very informative. That is a very large pack. No wonder it is so expensive.

85kwh battery pack is old, they have since introduced the 90 and 100 kwh battery packs on the previous generation Model S and X. They were called the 90D, P90DL, 100D, and P100DL.

Yes and the 100 pack actually has more cells and higher capacity than the plaid pack.

Backward compatibility is easier one. Future compatibility is not easy.

Thank you have a great week. Michael

Model S has more battery power than Model 3/Y -- may explain extra components. saving part numbers too

Great points on construction improvements.

Thank you!

For future shows: how about details on conducting quality control ? How do designers and manufacturers test for robustness, safety, resiliency, stress, repeatability, ...etc.

You can't really get that info from a teardown. You can see that the packaging is tight. Tesla's issue with quality control usually involves things like panel gaps and seals. You rarely see people complain about the powertrain.

It’s a Tesla. They don’t. That’s why they are on their third recall this year, still broken heat pumps, now missing hardware in cars sold as FSD-capable. Chrysler made better cars in the 1980s.

@@Ficon wow, if thats true tesla has the least recalls of the entire industry, mercedes had 18 last december alone for example. of course they test everything and learn from the customer experiecne , there is no better way, no matter how much you test, the real test is the customer.

Great job guys! Tesla is so impressive with each subsequent revision improving. Maybe use the pointer sticks to highlight the subframe etc, helps focus the discussion to the part location. /cheers ScrapBongo Liked

Great insight, thank you!

Instead of laying the 2 parts flat horizontally, it might be clearer for viewers to view your layout vertically. Against the wall or whiteboard.always love your Tear Down information and improvements

It will be interesting to see if we hear about that DC-DC converter once someone who understands it takes a look.

I'm a Canadian pursuing an engineering degree, hopefully I can one day apply :)

Popper evolution under the hood! I like it!

This is so great to see, the Magic is in those Chips ; )

When they showed the underside of the filter board housing there are two blank coil housings. They should have drawn the insight that those are likely either utilized in another vehicle or will be. I’m thinking cybertruck. So the filter board housing is likely designed for multiple vehicles.

No, it was just dumb original design. Instead of having a large transformer to reduce outlet voltage at the input as on the Model Y they allow higher voltage to flow through down the line and then use smaller transformers (as they now have 4) to further reduce the voltage. The coil at far left end was used as part of the LC filter, which in the latest version is replaced by a ferrite choke (to suppress high frequency noise).

​@@amimartian I understand your confusion, since the input coils on the older design really look like plain mains transformer, but both older and newer version are 3 phases switching converter designs ( @50/60Hz, you simply cannot pass several kW of power through any transformer small enough to fit here). The missing input coil were inductor ( probably common mode ones ), designed to prevent "leaking" the high frequencies into the mains. As Mikeselectricstuff said in his comment, I think they simply increased the working frequency of the converters, which requires far less filtering, hence the smaller input and output inductors ( roughly said, as frequency increases, magnetics can get much smaller and still perform the same job). The added small transformers looks like gate driving transformers, they are far too small for being part on the power path, this is probably related to the frequency change. Cannot wait to see more from Sandy on this subject.

Smaller filter with fewer/smaller coils only come with an increase in switching frequency. Increase if "effective" switching frequency can be achieved by switching faster, using a multi-level or interleaved topology. Additional gate-channel isolation transformers as well as fuses will ultimately result in more semiconductors below the PCB. The additional semiconductors can then be used in parallel reduce losses and allow for higher switching frequency. Alternatively a multi-level or interleaved topology could be used to achieve a similar result.

Great video as usual!

Top class presentation. Thnks.
