Moving On Up: Exploring the Cybertruck's Power Conversion System & 48V Architecture

[@darwinboor1300]

Thanks gentlemen. As an engingeer it is always fun to have Munro and friends provide us with quality images and explanations of the evolution of Tesla EVs. Congratulaions to the Tesla power electronics team. Yet another set of major advancements in PCS2. From those of us in the path of Helene, my wife and I wish we had PCS2 in her Model S and I in my Y. A neighbor with a Rivian powered their house daily from his Rivian at 5% of full charge per day. I bought more gasoline than we had purchased since I got my Y 3.5 years ago. Just under 20 gallons per day for my 9 KW generator. During the outage, I spent more time in gaslines than I did supercharging my Y twice during the same interval.

[@noCOtwo]

wow the difference between old and new is stunning

[@markharmon4963]

I reluctantly clicked on this video and found it fascinating that the architecture can be so different within a few months of production.

[@niftybass]

I got the impression PCS2 was what the Cybertruck started with, and the older one is in S/3/X/Y, but maybe I misheard something.

[@Mrbfgray]

Fascinating indeed but I clicked immediately.

[@georgepal9154]

The PCB being the transformer coils definitely blew my mind. That is very clever. Avoids a lot of coils windings. You could swap out just the ferrites without changing anything else and you'd have a completely different profile for those coils.

[@MrAdopado]

True ... though traditional transformers are very reliable in my own experience, whereas PCB board tracks not so much!

[@Idiomatick]

[@hoffinger]

Using the printed circuit board for ferrite winding is genius. Having worked on wire wound devices like speakers, and induction coils for 50+ years I have found the wire coating to be the most common point of failure. Have to resolder the connections. Just did the tweeter on a 70 year old KLH and a pair of 20 year old Alesis speakers.

[@johnpublicprofile6261]

AFAIK it is not a new technique. But using it in automobiles probably is, as probably is such high ampage and production volume.

Probably using Silicon Carbide Mosfets so they can run at higher frequencies which will use lower value inductors which can be PCB layers that will be plated up to at least 2oz copper.

[@AustinFerguson]

So fun fact - My new 2024 Model Y had a failed PCS module right at the start 500 miles into ownership. When I was at the service center the tech mentioned the part and showed me - PCSv2 - Revision 4 that was failed in my car. My model Y PCS board LOOKED absolutely nothing like this one did in this video and more like the Cybertruck, just FYI. In fact it was so different the service center waited on a engineer coming up to work on a Cybertruck to help diagnose / replace / re-marry this component to my car and get the profile / software reload to take (they were fighting this for a few days). The engineer said that a line change that happen they upgraded a few power modules on the cars that increased efficiency? Nothing else to note. A few memory notes on my board was it was smaller than the Cybertruck and had half those chips - but defiantly had none of the original capacitors shown in this video.. I believe there pushing forward on there new models as they always do...

If their new PCSv2 is bidirectional just like the Cybertruck’s is (and I don’t see why it wouldn’t be), then Tesla could actually offer PCS upgrades for such functionality and I’ll bet a lot of people would take them up on that offer.

That is an amazing PCB and they seem to have mixed high current paths with fairly fine pitch SMT components, and it’s also rather large as well. The layer stack for this board would be very interesting on its own with the planar magnetics and lots of higher frequency switching. Fantastic work by the engineering team at Tesla ❤👍

[@WarrenLacefield]

I think the original PCS-1 board design and build was very, very good (way more than a textbook design and focused directly on the power needs of the vehicles). However, this new PCS-2 design really seems, IMO, to take things to the next level (and provide redundancy in the same footprint)! The idea of printing planar (on CB) inductors is not totally new, but to get all that to work elegantly in real applications, seems state-of-art to me. Congratulations to the Tesla engineering and circuit board design teams that created both of these solutions.

[@46I37]

Halfway through the video, they are comparing parts that do completely different jobs. The big white toroidal looks like common mode choke to stop the switching noise propagating out of the convertor, and the transformers look like they are missing. The new design with the ferrite brick transformers in the middle are clever, but a concept I saw in a Metrohm power supply 20 years ago. Still great engineering.

The "Clever" bit here is the almost complete reduction in damping / smoothing capacitance. Ok, a fundamental frequency uplift enabled by SiC switches is going to help, but the amount of work required to optimise leakage (primarily inductance leakage) paths at a pcb level is significant!

[@SeaMushroom98]

I wouldn't refer to those as "power transformers" they're actually planar transformers (because all the windings are contained in the plane of the PCB). A transformer meant for power can take any form.

[@ForTheBirbs]

THANK YOU for the t3ch talk. Really interesting. Cheers

[@yiqiwang4506]

One of the major advantages of 48V system is higher voltage and lower current. For a conventional DCDC in EV usually rated between 3-6kw (250A to 500A), it is a little surprising the 48V system is rated 400A, is that the short duration peak current capability?

[@edc1569]

its because the Tesla needs so much 48V for power for the electronic steering system

[@junkerzn7312]

Supposedly it is also supplying the base 48V to the inverters in the bed supplying 120/240. Still, 400A @ 48V is 20kW... that's a lot of power, so they might just be talking burst or bus bar specs and not continuous conversion specs. That said, DC-DC buck conversion is very efficient... they should be hitting 98% to 99% efficiency so there is no particular reason why a board like that couldn't do it. At 99% efficiency it would have to dissipate about 200W worth of heat.

[@patmcdaniel2016]

Great stuff.

[@absolutionYNWA]

What a video! Thanks for the insight! I remember In the very first Munro video with 5 Tesla chief engineers just after cybertruck was released, they did mention that the HV/48V DCDC converter is still 3kW. So I am just wondering two questions: 1) For the redundant design, is it 3kW each or 3kW together? will both part work together in normal operation to provide half of the required power each, or only one work and the other one take over only when the first one fails. 2) If the maximum current is 400A this is definetely not a 3kW DCDC converter😅So what is exactly the nominal power of HV/48V DCDC converter

[@philtrubey7480]

So how’d they get rid of the bulky electrolytic capacitors?

[@ch4.hayabusa]

@@philtrubey7480 see PC motherboards... They all switched to Aluminum Electrolytic, Tantalum capacitors or a hybrid of the two.

My modestly educated guess is that they moved to a higher switching frequency, spreading that otherwise higher thermal hysteresis load over a larger lower saturation driven core. Those smaller current cycles would allow for a drastically smaller cap volume.

[@junkerzn7312]

@@eelcohoogendoorn8044 That's what it looks like to me too, particularly given how few PCB trace windings are going through the ferrite core pairs. They could have gone as high as 2 MHz. Anywhere from a 200 KHz to 2 MHz switching frequency.

[@wtmayhew]

I give a thumbs up to Tesla for the engineering of the 2nd generation power converter. The planar transformers are a smart way to improve reliability. Eliminating the large electrolytic capacitors is also a big gain by eliminating components which are shock and temperature sensitive. The downside is that the semiconductors are probably more expensive. It is good to see the redundant 48 Volt supplies. I would have expected no less because the vehicle has catastrophic loss of control if the DC power fails. It is pretty bold of Tesla to have gone completely steer by wire. I prefer the Nissan Q50 approach of a clutched intermediate shaft which allows steering in the case of lost power. The Tesla steering rack is doubly redundant with a third sensor as a backup vote. The gain by going strictly by-wire is that it enhances the flexibility of arranging the interior space by eliminating the intermediate shaft. Tesla fans point out that Airbus has a glass cockpit with fly by wire, but the aircraft system is triply redundant with the third circuit not having a computer. Each circuit is also multiply redundant within the circuit. Of course an aircraft malfunction can affect the safety of hundreds of occupants while a vehicle crash typically only affects a few people.

It would be nice to have more 'layman' explanation as to what and/or how the components worked. Like the ferrites and coils and chips. That is what made these videos great in the past. Knowing that a large number of viewers do not have the technical knowledge.

[@morrisg]

So the old transformer has a coil of copper wire that is fed through the center of the circular ferrite, so you need a machine that can do that wrapping efficiently. Then the wrapped ferrite copper wires have connectors to make the connection to the printed wiring in the pcb. All expensive operations. Compare that to the wide copper traces inside the pcb which do the wiring and the ferrite rectangles which have a top part which mates with a bottom part on the back of the pcb, so that the ferrite "box" encloses the copper wiring within the pcb. Much cheaper to produce. In addition, as the control electronics get faster the higher frequencies mean you can use smaller inductors and capacitors for the same power conversion capability. Bottom line is that Tesla is using state of the art power electronics design to reduce costs and improve efficiency.

[@vr4042]

@@morrisg I get that. And it is pretty clear the simplicity in the new board versus the old. But prior to Corey leaving they were much better at explaining in layman's terms what and how things work. In this video they say here's the coil. But then they don't explain really what the coil does, or what the ferrites do. So its not just the how is it better, it is also, what do all the better parts actually do. I'm sure insiders got all of it and understand a lot.

Dear youtube.com/@MunroLive, sorry to say, but what you are saying at minute 7:00 is simply wrong! You are talking about the redundant DC/DC converters, but it is the AC to DC stage. It is even marked as DC/AC 1 & 2. Actually the orange connector is the 3 phase + N AC input. I hope this is correct in your pricy report ;-) I guess the white connector is the HV DC output and the blue connector is the LV (48V) output. The big planar transformers are part of the conversion stage (AC to DC). BTW: Planar transformers are nothing new to automotive. A similar concept was already used in the DC/DC converter of an ID.3 (MEB).

It’s pretty cool but I still think it’s a miss not including 2 of them (as well as 2 charge ports). They already split the battery, so it would literally double the charge rate both for DC and AC charging, maybe less on the DC depending on cooling. It would also let me charge and export power at the same time, which would be nice for RV’s passing power through from the post.

Instead the DFMEA probably called for full DC-DC output in the event of a failure, and the max demand from the 48 V loads is never more than 200 A.

[@Mathis218337]

So does this mean the PowerShare can do 400amps? Crazy.

No. PowerShare can provide 48 A at 240 V. It is using the 48 V on-vehicle charger in reverse, as this new one is bi-directional. The 400 A is the output of the two redundant 800 V to 48 V DC-DC converters, 200 A each. This was explained in a brief caption near the beginning of the video.

This is all very basic stuff for anyone involved with current state of the art power conversion, even on small scale power supplies.

[@junkerzn7312]

Nvm, I see what they could be doing. They must be chopping the AC directly and combining the chopper and the rectifier together with a synchronous rectification design. So the input stage is basically just a current pump. Which makes sense because it has a battery pack's extremely low impedance that it can push against. We need to be able to peek under the plastic on that input stage before the planar magnetic elements. There is still a lot of EMC missing that has to be there somewhere.

pity he would say what he knows or have done his home work and red his crib sheet

I used to watch these videos when it was Sandy presenting

[@MunroLive]

Sandy is a busy man.

@@MunroLive I enjoy all Munro videos, regardless of who's hosting

[@WarrenLacefield]

Yes, I enjoy Sandy's presentations as well. However, for a software-defined vehicle, there is a huge amount of highly specialized knowledge in electrical engineering; power and control management; and software design, coding, and implementation that goes way beyond ordinary ICE cars. Sandy has a multi-disciplinary team to help him disassemble and reverse engineer all of that. Tesla has fantastic multi- and inter-disciplinary design and engineering teams who create all of this essentially from scratch and first principles. In fact, this is the major reason, IMO, for the difficulties that legacy auto-makers encounter when trying to compete with Tesla or the Chinese EV start-ups.

Thank you!

[@huangbad]

Good talking. Just no key information.

[@MunroLive]

That’s because it’s in our reports!

The most boring silly old farts, just not Sandy

[@ThomasHaberkorn]

Great technology, but a product which will not help to stop the experiment we do with our atmosphere. Tesla, go learn from Fiat Topolino and such

If you guys don't find anything interesting you don't have to fake like it is

[@MunroLive]

Lots of interesting findings in our report!

[@johnpublicprofile6261]

Just the fact that bidirectional charging has been ADDED whilst at the same time reducing size and weight is definitely interesting. Also, the removal of the electrolytic capacitors (can shapes on the older boards) means a large improvement in reliability and a huge improvement in board lifespan. That's interesting! And you can be sure that those improvements will be added to the millions of cars of the other Tesla car models that are going to be made.

@@johnpublicprofile6261 Eliminating the capacitors which are temperature and shock sensitive is pretty interesting to me too. There is likely some cost to making the change because the semiconductors are probably going to be more expensive. There may be some engineering by lawyers hiding in the background. The redundant 48 Volt supplies are an absolute necessity because loss of the 48 Volt power results in being unable to steer the vehicle. I wouldn’t want to be one of the engineers on the receiving end of a lawsuit resulting from a crash due to loss of DC power.

@@MunroLive I felt like there was an appropriate level of disclosure here to lead people who need to know detail to obtain the report.

[@GrandHuevotes]

Sounds like you’re bitter about Tesla. You probably want your Kia or whatever it is you want to have the spotlight lol

[@truthseeker111]

Too bad Elon is a douche 🇷🇺 Half of us cancelled our Tesla’s. Every timeline he projects is false, can you imagine the short cuts just to get it to production! I took one look at mine & walked! It’s a POS

[@tedg1609]

How’s bankruptcy coming along at your fossil car stealership ?

[@danieldimitrov9969]

I bet you your opinion is based because of him supporting Trump 😂 Go cry to Biden/Kamala they will bring some illegals in your neighborhood. Truthseeker my a$$

[@jamesengland7461]

Why does every one of your statements sound like the opposite of truth seeking?

[@mini2nut67]

The cost cutting, innovation and thinking outside the box mentality never stops at Tesla. They employ some brilliant engineers.

[@carholic-sz3qv]

Lol!! You mean making vehicles less and less repairable right! That single board fails and the vehicle is not operational.
