No no no no no! PLEASE, do not start collaborating with random TH-camrs. I come here for real engineering, not dudes that scratch phone screens for an audience of teenagers!
Super cool battery pack! Thanks for letting me be a part of the teardown!!
Our pleasure!
No problem Jerry or is it Garry
@@jkroiss with two j's.
@@jkroiss I think that i can sort out this Jerry Garry problem. It is Gerry. A is E.
@@jkroiss its Zack anyhow haha
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!
The end just made my week a lot better. Thank you so much, team!
Mr.Munro is now full fledged TH-camr 😁
That was great
TH-cam 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
Jordan is awfully good at these. Not just the expertise, which is pretty obvious, but the presentation too.
Yeah like made for it.
That ending literally had me laughing out loud! Thanks for enjoying your moment!
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
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
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!
More Step Brothers re-enactments please.
Lets get some Ricky Bobby in there too! C:
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.
That Step Bros bit at the end. Love it!!!!
ok the ending was awesome. can't we have more of those?
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
Thanks Jordan and Antonio for the details of the Rivian battery. I LOVE the hilarious SNL ending!
Nice tear down today. The Step Brothers ending was the icing on the cake!!
THANKS JORDAN,ANTONIO, AND ZACH ALSO ALL THE MUNRO TEAM…FOR DOING THIS AND EXPLAINING FOR US laypeople 🤔👍😎💚💚💚
Hahaha …. stay for the outtakes at the end 😂.
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!
🤣🤣🤣can't believe they did step bros. Hilarious
Sandy Huff and Cory Doback killin' it!
Ending is Superb!!!!!!!!!!! Hello Ms Lady!!!!!!!!!! Sandy finally hits the big time.
Your comedic skit is hilarious. Thanks.
I have a feeling the HR hiring video at the end is just a compilation of real-life situations that have happened during all their interviews so far.
Ending is legendary. Good job step brother.
Great job Jordan prompting Antonio for description flow.
End video was awesome and shows your team can have fun!
funny skit didn't see that coming. now we know why we don't see Sandy he's in the back making skits.🤣
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. 😀
12 volt
@@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.
@@mrknesiah A 12-volt lead-acid battery would actually actually SIX more cells.
So yeah, Rivian lies. They're as truthful as a spherical earth.
Guys, this was so well done. Your explanations were clear, concise and easy to follow. Great job!
Really liked how you added more engineering information into the discussion, adds a lot to the education value.
Greatly played at the end 😂😂😂 👏
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
What what? No souvenir from Pann? Or was it Panm? What a bummer!! 😂😂😂👍👍⚡⚡💃
Love Zack. Glad to see you work with him.
What in the heck.. that was hilarious. Also, very nice detailed video on the rivian batteries :)
thanks
I love the Bloopers at the end of this video, LOL,,
Such a cool look inside the Rivian, only place to see this fabulous tech
Ok these skits, straight fire! 🤣
And boom goes the dynamite! Thanks for the extra effort at the end there 🙌🚀
PANN?!? Yes! Awesome!
Love the actual content, but man that skit at the end was worthy of a TH-cam Emmy! 😂
I love when my favourite channels colab
🤣🤣 that ending made my day
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.
Nice work guys… all of you
Like the spot at the end.. nice
Ok the stepbrother ending was awesome. Cory looked like he killed his sole to keep from laughing.
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!
This was fantastic
love the skatch !!!
That end blew my mind 🤣🤣🤣
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.
😆the bloopers at the end! lol
Ending is gold! Still waiting for that roof BBQ explanation😊.
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.
Definitely has the luster of nickel, maybe tin, certainly not aluminum.
Great tear down, Not sure what was going on at the job interview at the end of the video :)
Munro step brothers is awesome
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.
Cory nailed that interview, and I think Pann was rude. She didn't even have a tuxedo on.
LOL! Glad I watched to the end
Jordan is JACKED.
💪
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?
Those heavy side plates would be a good start
We will all laugh at how heavy, complex and humungous vehicle battery packs were in 10 more years. We are still in battery pack infancy with a lot of room for advancement.
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!
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.
The Step Brothers reference at the end was prime!
I love the ending 🤣!!!!!
Pann is awesome :)
End was great😂👍
Thank you!
You're welcome!
Not getting the 7777. 2170 yes but not connected with size guys. Love the breakdown 🙂
I'm Cory's step brother.. OMG. died laughing.
Thanks for the Easter egg at tha end🤣
wow that was a hilarious skit
That 4860 pack that you did awhile back sure looks way cleaner.... sans the pink structural stuff.
These tear-down's are great -- much more interesting than the design-oriented episodes.
Are you guys will do a teardown and comparison of the Rivian Computer vs Tesla Computer and ADAS???
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.
Last part is probably based on real events 😂😂😂👏👏
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
Prestige Worldwide
Nice bonus content at the end :)
Thanks! 😁
Funny ending…!
So, is the negative pole of the battery soldered to the current collector on the top of the cell or on the side? Thanks!
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!
I’ve been looking for content with this combination of depth and accessibility for years
I like the Model 3 SR, LFP battery pack the most. Seems the best to repair.
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.
If you watch lucid video of the ceo he did the same thing for the cooling too with a non stacked battery modules
Someone makes flexible plastic coming channels. Miba
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 TH-cam 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.
Hi guys!
Di you happen to know how the voltage sensing harness connects to the cells?
That bit at the end when Sandy came out from behind Corey was kind of like a Russian doll situation. 🤣
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.
"You're coming off as a little stupid." 😆 🤣 😂 I had a good laugh at that.
More about Rivian!!!
0:20 You had to bring in Zack from Jury Rig Everything -- must have been a tough nut to crack.
Where is Mr Monroe? Good video guys.
Sandy was in Vietnam when this was filmed.
No fasteners so he wandered off.
Why does everyone think this is an Office skit. It’s Step Brothers Will Ferrell
Neat!
Do you guys have a XRF Analyzer like they use in metal scrap yards? Just curious.
yup
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.
