I fell asleep during the battery part and woke up when Pamm yelled "get out of my office!" and could not figure out what kind of weird dream I was having that Sandy was in The Office!
I have a feeling every EV manufacturer must be praying to the battery gods to find a simpler solution. It is mind boggling the amount of steps and technology that goes into putting together these battery packs. Thanks , again, for the awesome tutorial.
Well that was an interesting ending lol. I can really hear the Michigan accent in Pam's voice, it's not a bad thing though. I appreciate the explanation about the different types of batteries too. I didn't realize that although the prismatic and pouch cells are more energy dense, but when all put together in a cell module they end up being about the same as the Tesla cells. It's always something screwing with cell efficiencies when bundled together to make a huge battery pack. I have a 34' class A RV that I outfitted with ten 100 amp hour LiFePo4 batteries (Battleborn) mated to 2400 watts of solar on the roof and ended up changing out the two roof AC's to one minisplit heatpump to both heat and cool my RV along with other things that I changed out for optimal efficiency, so I can now run my everything in my RV 24/7 without plugging in or running my generator! Lithium cells are a real gamechanger in many ways and I'm excited about living off-grid without sacrificing any of the conveniences that require power. I love your channel and your overall philosophy regarding efficiency in manufacturing, the OEMs should be flocking to your company for input!
Interesting how different the battery pack designs are between manufacturers... thanks for the sise-by-side of the cylindrical, prismatic and pouch form factors. A picture is worth a thousand words. SoCalFreddy
Small issue with the title: You show that one brick is 72p (18 x 4 cells). Then 24 cells horizontally dived by 4 is 6s on one side and therefore one half is 6s 72p. Both halves together is 12s 72p. If you disassembled the 135 kWh battery pack, then there are 9 such modules. In total: 9s 12s 72p which is 9x12x72 = 7776 cells. In the title you tell us: 7777 cells. Where is the extra cell? In the flash light of the Rivian. 😀
@@mrknesiah Does not fit: Rivian has 2x 12V batteries. See manual or Munro "Rivian R1T Teardown | Frunk removal". They are the red bricks near the air intake. Both likely lead-based, and therefore 12 cells in total. Even if they were lithium-based, they also would be more than one cell. And for sure, these low voltage batteries are not made from the 2170 form factor cells that the traction battery is made of.
@@koeniglicher Zach explains the cell count in his video, 7776 in the drive battery, 1 cell in the flashlight. I wonder what kind of batteries are in the bluetooth speaker.
5:50 When you see coloring through, that typically indicates nickel or tin coated copper. You should be able to tell simply by the weight whether it's aluminum, but based on the volume and current capacity, I can't see how those aren't copper.
21:20 well that woke me up. the pouches are definitely more dense even at the pack level which is the reason most of other EV makers enticed to use pouches. however pouches are worse for reliability, stability or safety. this is the reason why Tesla insists on more expensive, more difficult cylindrical cells. anyways, it is a good thing Rivian is going with LFP cells in the future. It is time to move on from these relatively costly but high performance packs.
Having worked on the assembly line for Tesla battery packs at Giga 1, I find it very interesting to see how other EV companies design and manufacture their packs.
So each Rivian module is 12s72p which is a departure from 3 years ago when it was 96s9p. I have pics of the old module which is how I figured that out. So the old module at 96s was the full 400v nominal pack voltage and adding additional modules in parallel added capacity. Now it takes 8 modules to achieve the 96s full pack voltage. Perhaps a pack capacity expansion now means adding a module or two in series to boost the voltage above 400v, rather than another full 8 modules in parallel to double the capacity. This would imply the controller and charger can handle 10% higher peak voltage which is quite possible with COTS mosfets. IIRC the battery expansion capacity goes from 135 KWh up to 150 KWh which is about 10%, but I could be wrong about that.
What I have in my database on battery packs: Rivian 135 kWh = 9s modules of 12s72p = 108s 72p. This is likely what they have on the bench there. Rivian 180 kWh = 12s modules of 9s96p = 108s 96p. This is likely what you refered to, but misspelled is as "96s9p" what is actually 9s96p. In both cases nominal battery pack voltage is 108s times 3.6V = 388.8 Volts. The modules themselves share 12*72 = 864 = 96*9 cells. Rivian just changes the current collectors to get different kinds of modules for different kinds of battery packs.
@@koeniglicher Great info! Rivian is only shipping the 135kWh packs right now. I had pics of the Rivian packs from 3 years ago and it was 96s9p. They took two columns of 24 cells and connected them in series, so there were 9 of those in each half. Then the end plates that connected the top half module to the bottom half made the parallel connection. Apparently this didn't work well in keeping all the cells balanced at each step and they changed it to what we see in this video.
14:35 .. The key to welding exaggerated thickness variance is preheating. What you can do to weld those little foil pieces on is lay your larger/ thicker bus bar into a hot place so that it's already preheated -- then when you apply your foil strips, you can quickly braze it on before it burns through and move on to the next one.
Thanks Jordan and Antonio great detailed explanation. I was just curious if you had any suggestions on ways that Rivian could save weight with the design of this battery pack?
Curious on efficiency of Rivian sandwich plate cooler; varying from Tesla wavy extrusion cooler; any other designs in use for removing heat from cylindrical cells?
Upside: Plate cooler is lighter and allows for higher power density. You can put cells closer together because you don't have material running between them and less plumbing to each extrusion. Downside: Less surface area touching the cooler and you rely on the can to transfer heat from one side of the cell to the other. This can be mitigated by a pumping coolant at a higher rate through the cooler. Neither plate cooler or wavy extrusion (ribbon) are superior in all respects, just require different design considerations.
Another great one. Have you considered going for a lucid tear down? Can you share any dimensions and weight of the full pack? I had a quick look at their stuff and it seems the motor and drive train might have some cool and innovative ways of solving things.
Lucid puts out great videos breaking down their own tech. Unless you want Munro to do a cost analysis, I don't really see why they would need to do Lucid tear down. A price on the efficiency gains from the motor would be nice.
14:15 Welding a thick material to a thin material, if you apply heat to the back of the thick material, it would heat up to accept the weld, then let the thin material melt enough to weld? Or add braising material to the thick material before braising, then add heat to the back of the thick sheet until the braising sticks to the thin material? I don’t know if that makes sense.
what boggles my mind, is the fact that I'm looking @ a battery pack. where all the batteries each make up, rolled-up coils. which create's each little individual battery! 7777 of them!!then! it's designed 2 be cooled! cool stuff! love the comedy endings! do magic tricks 2! well done! congrat's everyone!
At 14:00, those current collectors don't appear to be symmetric? Unless the top collectors have an opposing asymmetry? I wonder if the current path equivalency is overlooked sometimes? Meaning that some cells will carry more load than others simply due to the slightly longer buss lengths to each cell relative to other cells.
Once again excellent tutorial! Your content of the videos are most of the time SO important and interesting that one has to watch your tutorials. However, I feel that your tutorials can still improve a lot in impact if you prepare a rough script and even more if you improve the camera (which in the case of this video is probably an iphone , which in my opinion is not good enough to show the needed depth of field in close-ups, sharpness, dynamic range etc.) movements etc., which for such important topics and issues are often far too fast, shaky and not clear enough e.g. when zoomed in to show details). I hope you don't' mind me pointing this out, as your channel is so important for wider public education and us specialists to learn in greater details reg. the various EVs. So thanks for your great work!
Would like to know what is the material used for side plate and any coating is done on that for electrical isolation? I came across Stainless steel as a side plate material with powder coating, is it possible to replace powder coating with Nylon/ PPS gf40 for electrical isolation... Thanks
That is really clever to have the base of the cells from each side on the cooling plate. Additionally, I bet the "paint" on the cooling plate is a thermally conductive electrical insulator. It would be interesting to see what that coating material is, but I suppose that info won't be on the free RUclips report 🙂 BTW, base cooling of cylindrical cells works great, more uniform. It's much more uniform than side cooling, especially on thicker cells (& why the Plaid uses 18650s). Tesla originally showed base cooling for the 4680, but then abandoned it. I find that curious. I thought the improved end cooling was the best feature of the 4680.
20:23 That isn't always true, and lot of the pouch and prismatic cell packaging is no more substantial than cylindrical cell battery packaging. In fact, the only real difference between prismatic cells and cylindrical cells is shape. Both types of cells are designed to operate with minimal packaging, and they can often operate completely free of any additional packaging (though for automotive use, you have to account for vibration). In fact, this is starting to sound a bit like misleading advertising in an infomercial for cylindrical cells. The power density for cylindrical cells is typically higher than pouch or prismatic cells because of thinner electrodes, but the energy density chemistry for chemistry is often lower for cylindrical cells because there is less active battery material per mass because of the smaller size relative to the mass of the packaging. Prismatic cells tend to be larger in scale, so they have more active battery material relative to the mass of the casing; however, the jellyroll electrodes in prismatic cells can result in a variety of power densities from thick .5 C to thin >5 C electrodes. Strategies for packaging the cells can vary, and each packaging strategy can result in wildly different pack energy densities, based on the specific types of cells used (regardless of format) and whether the battery case itself is a structural component. For example, the outer case (made by Magna) of the GMC HUMMER EV's structural 200 kWh battery pack is 450 lbs, but the non-cell weight of a Tesla Model 3's non-structural 82 kWh pack is ~400 lbs.

That was great
RUclips for Munro has gone from awkward early days to something they have a lot of fun with.
OMG so unexpectedly brilliant. i couldn't believe my eyes for a minute there hahaha
hey i recognize this guy
That ending literally had me laughing out loud! Thanks for enjoying your moment!
The ending was hilarious. It’s like your in a screen test for The Office.
It was a bit from the movie StepBrothers with Will Ferrell and John C Reilly.
So much room for activities
I fell asleep during the battery part and woke up when Pamm yelled "get out of my office!" and could not figure out what kind of weird dream I was having that Sandy was in The Office!
Top notch stuff!
Jordan is awfully good at these. Not just the expertise, which is pretty obvious, but the presentation too.
Yeah like made for it.
Excellent analyses Jordan and Antonio - thank you! The SNL skit at the end is pure insanity!
Much appreciated!
not SNL... Stepbrothers.. the movie.. WIll Ferrell.. and the other fella who's name i always forget lol
Nice to see Zach at Munro, I'm sure he was excited to learn some best practices for his "not a wheelchair" off road mobility chair
Was neat seeing Jerry Rigs Everything there at Munro!
Yeah, we had a blast together.

The end clip was too funny, didn't know you guys had such a good sense of humor. It made me laugh, well done!
Nice tear down today. The Step Brothers ending was the icing on the cake!!
We make a component in that battery pack. So COOL to see it in the pack and to have Munro live tearing it all down. Interesting.
Which one and what company
That Step Bros bit at the end. Love it!!!!
More Step Brothers re-enactments please.
Lets get some Ricky Bobby in there too! C:
Ending is Superb!!!!!!!!!!! Hello Ms Lady!!!!!!!!!! Sandy finally hits the big time.
Your comedic skit is hilarious. Thanks.

Hahaha …. stay for the outtakes at the end 😂.
Ok these skits, straight fire! 🤣
Going to be fun recycling those packs with the poly adhered to everything.
They talked about that on the 4680 teardown. Basically, it's not a problem once the pack is ground down/shredded in the recycling process.
Much better than the unrepairable Tesla 4680 piece of garbage. At least the modules can be removed without destroying the battery!
