Tom is your new TH-cam star. Intelligent, clear, and easily understood. Thanks.
Tom is a superb educator ❤
He obviously knows his stuff and is able to articulate it well.
Tom is good! He has appeared in other videos, not his first rodeo.
Kudos for the editing. Cold openings and out takes make this engineering channel all that more special. Thanks Team Munro!

I was about to make exactly the same comment. This is the first ad since a long time that I actively have watched.
What was produced in the clip, it looked like battery connectors, but what does the combination of different alloys do? Is it a stability thing?
@@wiegelmfg all ads should be like this. I watched the whole things
@@Pyamamannetje Thank you so much!!! We are so glad you enjoyed our ad 😀
Battery configuration: likely 192s 7p, which would be about 705V DC nominal. 4 modules of 336 cells each. The 4 modules are 48s 7p each. To be confirmed once they can look under the green foam which may hide a couple of more cells at the ends. There is a switching circuit that can either switch the pack to 192s 7p (all 4 modules in series) or 96s 14p (2s2p of the modules).
Regulatory filings show 816V and 150Ah -> 224s6p
Video timestamp: 15m 50s
48s x 7p x 4s = 1344 pcs of 46800 Cylyndrical Cells
This Tom person is an excellent presenter. He and Sandy together are more than worth the time. Great work!
So happy when Sandy's on camera! His team is great, but nothing beats Sandy's presentation style.
Same but also grateful they are showing off the other talented people at Munro. Keep it up!
"Uhm, ah yeah. I really think that, uhm, do you, ah, is that all you wanted to say?" isn't exactly a great presentation style, in my opinion. Whenever Sandy is talking the engineers/mechanics on camera with him look sooooooo uncomfortable. Their breathing and eye movements especially stand out, and they obviously fear correcting or disagreeing with the things he says. When Sandy is waxing poetic how everything they've seen so far in this teardown is wonderful and great and amazing you'd expect the engineers to nod their heads, add agreeable vocalizations, etc but instead they get shifty eyed, shuffle slightly, and remain quiet. When their turn to speak comes around they quickly start on a new topic.
Sandy still remembers the model T production line, mumble mumble yeah these are great. Goes back to sleep 😴 😅😅
This is why I watch every Munro live video. Caresoft is a lot of fluff. Sandy is simple and to the point. Great explanation on the venting!
Thanks for watching!
sandy is great. Sometimes he likes to go on about tesla, but he adds humor, a ton of experience, and a laid back kind of attitude, but still insistent on details.
@@davidanalyst671 At times Tesla is worth going on about. A lot of what one sees first in a Tesla shows up in other BEVs. When will we see gigaCastings in ICE cars.
@@danharold3087 do castings make sense in ICE cars?
@@toronado455 Yes they are drivetrain agnostic.

So true. Worse than a new iPhone.
This is true. The new structural battery packs aren’t financially viable to be repaired. To get to a cell means destroying most of the pack so it makes no sense vs older packs.
However, with how strong each cell is now built and contained, with how much better the BMS systems are and with how much less parts there are (no more tiny little BMS wires like older packs) it’s also much more unlikely that the pack would need replacing in the vehicles life.
Of course, this is yet to be seen fully. But this isn’t anything new. A replacement engine for my 2012 BMW X1 would be around £1,500 and after labour would be £2,000 or so. Which is cheaper than it would be to take the engine apart and rebuild it.
I suspect by the time these cars/trucks are 11 years old like my car, a replacement pack if needed, would be around the same price. And they’re pretty easy to swap out too, not much labour involved
@@iambenmitchell
I look at my car (Renault Zoe) and I see it like this:
This car has 196 LG Chem E63 cells. Each costs about 25€ and needs almost no tools to replace. So in case 1 cell fails, I would need to replace 2 of them (battery is 98s 2p) and it would cost me 50€ in parts, and I could do it with 20€ in parts (including battery tester).
@Mladjasmilic
Or, you could say that loss of one cell would be insignificant.....
With 48(?) Cells per row, 7 rows per module and 4 modules, the vehicle has ±1,344 cells.
.
From recollection the Model Y pack had a welded cell connection plate that served as a fuse at the point it joined to each cell.
.
So, if a cell goes "high current" it would be disconnected.
.
If this happens, the vehicle (currently with a 125kWh pack?) Loses
125,000÷1344 = 93Wh of capacity.
.
That's ±0.74 *percent* loss per cell.
......
Congratulations on having the confidence (and ability?) to attempt repair of a high voltage pack.
You must be one of the very few with the knowledge *and equipment* necessary to lift a car (safely) then drop a pack from under the vehicle (safely) diagnose the problem, strip it (safely), replace a cell (you mean module?) Balance, then reassemble the pack/ vehicle!
.
I wonder how much investment in lifting equipment (etc) and time that might take?
.
I'm sure that mere mortals would prefer to pay for 2-3 hours of professional attention to swap a pack which will be greatly reduced in price when the original is out of warranty in 8-10 years.... Maybe? Rather than days of labour to strip, repair and refit the original with no guarantee of success and probably no warranty on the work?
I can’t explain why I find watching Munro videos so interesting, I’m in no way an engineer but knowledge is power
Same here
I look forward to every Munro video. Thankyou Sandy.
More of this guy please..
I watched at 2x speed and he's a very smooth talker and easy to absorb
Yep…watching Sandy open up these packs is well worth the wait. Does what ever is needed to get the job done.
This video is brilliant! I'm not an engineer but I learned so much as a lay person. Simply brilliant and so educational.
Watched the weigel ad with real interest. Hope he breaks the trend of 3rd generation companies. Seems like it will keep going strong 👍❤️
Thank you for your kind comment! We are glad you enjoyed it. 😃
19:00 The car/truck has basically one *wear item* that's worth 30K-40K USD and you can only hope that there isn't any unexpected fault in that part because it cannot be repaired, only replaced!
Any kind of individual cell level failure is a 1 in 1,000,000’s event. Designing in repairability is certainly more time and money overall than just replacing the whole pack in those extremely rare events.
@@TheConnor12500 If we assume that one cell has probability of 1 in million to fail, then a battery with 7104 cells (like in Tesla Model S P85) will work with probability of (999999/1000000)^7104 or about 0.993 or about 99 times out of 100. In practice, that tells us that 1 car out of 100 will have a failed battery pack if a single cell has failure rate 1 in million.
Create a battery pack with more cells and you'll soon have a lot more failed battery packs.
And I'm pretty sure that in real world a single cell has more than 1 in million probability to fail. Luckily, the cell manufacturer does some automated testing for each cell to try to remove the broken ones but this kind of filtering/testing can never catch all the failures.
There a few shops that are repairing cells
@@theyutzinator I guess you mean replacing cells because repairing individual cell would make very little sense.
Replacing individual cells is somewhat doable with Tesla Model S style battery, pretty easy in something like Toyota Prius and next to impossible to do with something like Tesla Cybertruck.
Good thing the warranty covers battery defects for 150,000 miles…😎👍🏽
Wiegel has my respect. Best information association with the content of a video I have ever experienced. Well done. Thanks to all parties involved.
Wow, that means a lot to us!! We appreciate it, and are so glad you found our ad to be interesting and informative. 😀 Thank you for your comment!!
The ability to pressurize the pack and a pressure sensor should also allow some diagnostics about whether there are breaches in the seals or a stuck open port. Hopefully this will make the packs even safer
could most likey be added with a software update. Especially since all the sensors are already there
@@SolarScootersuk It exists already most likely, its in there, somewhere....
I love the ads showcasing various manufacturers almost as much as the main content. Excellent!
Thank you for watching! So glad you enjoyed our ad!!
Remember the flood ports and compressor are a necessity for fording water. The water is usually always cooler than the mechanical parts or battery pack. When the void is cooled it will create a vacuum and attempt to suck water in where ever it can.
On a traditional banjo axle the breather on the top of the differential housing is a oneway valve to allow pressure out. When the housing is cooled in deep water the valve sucks shut. Water is pulled in past the wheel bearing oil seals .
The larger the air void in the battery pack the more 'air' needs to be managed. The compressor is critical.
Compressors are not the surest thing in automotive NVH apps

Glad you enjoyed it
Also, the batteries last time weren't an outrageously high price. Happy to pay more!
And on your results? Maybe there is a special treatment for you (or a car with an accident is coming up).
I think 70% of what is interesting can be retrieved without destroying the battery.
Just send the man a free cell Sandy.
Taking Sandy by his word, how did Munro lose a lot of money on that campaign then? Shipping? Man-hours?
Both apparently @@2nd3rd1st
@@Matzes I'll believe it. Especially if they forgot Hazmat on shipping. They don't have a major contract with a carrier to keep the price reasonable. Plus, this is the kind of company that is going to be paying a decent wage even to junior staff. Even more, digging batteries out of foam without damaging them, then cleaning them up for weeks on end has to be super boring.
Holy crap, Wiegel, the organization who sponsored this video are practically down the street from me. Insanely cool. didnt realize we had such advanced manufacturing here in Chicagoland still. I'm going to have to check em out!
I hope for Chicago's sake they stay.
Because the mentioning of a Mexico plant starting this year.

You probably won't see this but thanks Tom and Sandy for a great injection of positivity and technology. Really needed this today with all the negative things going on around Tesla (and the world for that matter). Cheers to you and the team - this was superb.
Fabulous episode. This is stuff that I really watch Munro Live for. Been watching Sandy since the i3.

This battery pack looks like repair hell. Also, it doesn't take much for the vehicle to detect that something went wrong: the HVDC system is continuously monitored for leakage. If water bridges anything HVDC to chassis, you get told to GTFO as soon as excessive leakage current is detected since there may only be one layer of protection left between you and 350-900Vdc.
It's repair hell because it's not repairable and it would just be recycleable.
@@Resist4 They removed an entire layer of recycling from the module. Conversions cannot use junk vehicles, and the modules as they deplete would need to be rebuilt in order to be used in the secondary application.
@@ronaldking1054 And as I said they are not repairable. Just recyclable, meaning the components would be broken down to extract the lithium and other metals.
@@Resist4 And you failed to understand when they stated that to break it down to cell level, Munro Live lost money.
@@ronaldking1054 you don’t have to break it down to the battery. You deep tank the whole pack and melt the metals to be separated, even Sandy said that in a video.
Wow! Amazing! I've been waiting for this for years. Thanks for the excellent job you guys do!
Smart guy there explaining everything! Great hire Sandy!! I don't know much about it but its fascinating to listen.
So the CyberTruck has a non-repairable battery.
Non maintainable battery. The battery can be replaced itself, i think, but not fixed or easily recycled into differenr uses.
Yes. This Design should be forbidden for every OEM by law. To protect the customer
@@HS2020Music yeah, lets throw some overbearing legislation and government burocrats to poke holes, and stifle all that innovation, if it was good for the Soviet Union, I guess it would fit USA as well?

Real engineers doing Gods work.
thank you munro for this precise and very interesting description of battery specs of the cybertruck, great job!
The air pressure addition would be useful if someone fords a stream with a hot battery pack, The cooling from the water in contact with the pack would lower the air pressure inside, possibly pulling water in through the vents. The added air would counter that. If any water does get in, there's plenty of space in the bottom to hold it until it drains or evaporates and exits via normal thermal breathing.
Good thought. Those pressure equalization vents are meant to stop moisture, not a vacuum sucking up water.
Prior to the 4680 cell, individual modules could be replaced to fix in-service faults but the goop used in 4680 designs would would seem preclude any form of repair. I understand that Tesla themselves do not provide a pack repair service and expect owners to stump up for a whole refurb pack. Third-party pack repair is however possible but far less likely for 4680 packs. I hope the failure rate of 4680 packs is sufficiently low that this approach to manufacture will not prove problematic amongst Tesla owners.
With this type of pack and all the adhesive, while technically possible it'll not be financially feasible to repair these packs in any modern country (too much labor time necessary). A civilization of waste and disposability... :(
@@TheFlatronify Yeah I am for them to advertise as recyclable is just a straight up con. This whole industry is based on lies
can only hope their quality control is high enough that cells or modules don't go bad. Perhaps potting the whole battery to this extent will somehow increase its life too
@@TheFlatronify yup, it essentially makes the entire pack a "throw away" if something goes wrong, and potentially the entire truck after just a few years too. this kind of anti-repair shit needs to be stopped.
It is criminal to make something with this much material and resources and not make it repairable. This should be a metric for Munro, not how easy stuff is to build and churn out…
That huge battery jack was really cool. The electric scissor jack they have the battery on is cool too. 💪🏽
Love how Tom breaks things down.
thank you sandy and team
I am as big of an EV fan as anyone, but my biggest pet peeve with these vehicles is the lack of repairability. Maybe using a rubber gasket in place of the adhesive around the edge or not encasing the cells in epoxy.
Making a battery repairable adds complexity, cost, weight and unreliability, better to design a battery that is reliable than a repairable battery.
Some EVs do use gaskets, and like any gaskets they fail over time.
@@universeisundernoobligatio3283 lol, sarcasm? Tesla just doesn't care about consumers
@@bullshitbingo2259he is correct in saying that making the battery pack serviceable would make it considerably heavier, larger, give more failure points and it would no longer be structural, leading to the chassis having to be stronger and therefore heavier.
You either have a car that is more efficient but less serviceable or one that is more serviceable but less efficient and more likely to needing to be serviced. There’s pros and cons to both.
@@streddaz nah that is way too simplified. You can have awesome efficiency and longevity if you work on all components and design them the right way, especially because all modern batteries are fairly efficient anyway if you hook them up to an 800V system architecture.
As far as I know the Mercedes-Benz EQXX does jot have a structural battery, and the upcoming CLA class does not have it either. Yet the EQXX is the most efficient 4-door vehicle on the planet and the CLA will be the most efficient in its class out performing the Model 3. The point is, this argument is just vaporware. The most contribution to efficiency has the drivetrain and motor, the aerodynamics and the system volt architecture. The weight and the structural stiffness are secondary at best, especially because overall engineering has become very good.
Tesla just uses the cheapest ways to produce components, and a structural battery plus a fixed chassis framework are easier to work on. This can have disadvantages, too. And especially for the end consumer the positiv effects might be minuscule. Tesla doesn't care about the environment nor does it care about the ownership experience and product lifecycle. They only care about their profit margins and that is not an achivement. BMW uses recycled materials and even creates or sources new types of materials for the interior and body panels of the "Neue Klasse. The steel they use is low carbon emissiom steel, the battery assembly will use renewable energies. And the battery pack as well as the whole car is designed to be easily recyclable. I am sure you can aslo repair them better than Teslas.
I occasionally listen to Tom on the podcasts, and he's always interesting. But this was him in his element. Excellent. Learned a lot, especially as I was thinking that those 4680 cells were suspended, but for why? The answer was forthcoming.
that commercial was fascinating! i'm impressed, again
An ad I actually like to watch! Holy carp!
We appreciate your comment!! Happy to hear you enjoyed watching. Thank you 😀
The Munro cold open is the best
I like Andrew, simply because just popped the plywood off instead of talking about how to open it ad nauseum.
Steel. That is the bottom of the pack.
It was fairly obvious they had been trying different things for a while, so Sandy having a thought is fine. Sometimes simple is best, and Andrew likely noticed there wasn't any foam on the sides like previous models. You can also tell Sandy wasn't actually upset at Andrew there.
Good working relationship between people at all levels makes this seem like a nice place to work.
Thanks for the education, Tom. Well done.
Cheers

@@tellyboy17 - Better to have a pack that never fails. As you add modularity, connectors, and can't deal with a little moisture, your pack becomes less reliable and may need those repairs you seem to want. Poor reliability is great for the dealers and service techs!

Thanks Sandy for sharing details of first impressions of the Cyber Battery Pack and Wiegel's technology.
Tom, I really enjoyed your analysis of the Cybertruck battery pack. You're a smart guy
I like it when Sandy does the commentary, he is just excellent. For example, The battery was opened up and I was thinking, "they could have fit so many more batteries in the sides". Only to have Sandy comment, "this is obviously the crash zone". It's like he knows what I'm thinking before I think it.
brilliant design. elegantly conveyed by Tom and Sandy in layman's terms. Much appreciated!!!
Glad you enjoyed it
Its a disposable battery pack that isn't going to be financially viable to replace. Once again Tesla has taken awesome tech and made it worse than a cell phone.
@@EthosAtheos was thinking the same , it wont be possible to diagnois any problems.

There need to be laws to make these batteries serviceable to some level. Sealing these things and requiring a full replacement for any failure is utterly ridiculous and not “green”
Making a battery repairable adds complexity, cost, weight and unreliability, better to design a battery that is reliable in the first place.
@@universeisundernoobligatio3283I've seen you write this everywhere where somebody questions the serviceability of this kind of packs. Not everything you say is necessarily true. Repairability and reliability are not each others enemies for one. And sometimes investing some money up front to lower overall costs or even being more 'green' is the way to go. Lets be honest: EVs are all about spending a bit more to impact the environment a bit less (whether EVs are successful at that is another matter).
@@universeisundernoobligatio3283 I've seen you write this multiple times in this topic. Some of it isn't even true: repairability and reliability are not each other's enemies. With some careful design, both can be achieved. However, this will cost some extra money, but sometimes investing some money up front will bring greater returns afterwards. Or even investing some money for 'greener' results is worth it. Isn't going to EVs supposed to be one big exercise in spending a bit more for greener results?
@@universeisundernoobligatio3283 It also makes the vehicle a write off out of warranty… Thats not green, you need to be able to replace at least one section of the pack at a minimum to save 75% of the materials. And not I don’t mean user servicing, I mean any servicing period, even a dealer…
@@universeisundernoobligatio3283 It would be stupidly easy to make the lid removable with redundant gaskets like O rings on these packs and be serviceable… It is criminal to use so many resources in these packs then seal them for life. Im not saying users should have access but dealer or workshop servicing at the very least…
Anybody thats done legitimate off-roading knows that cover is absolutely going to get pierced if people push it.
The aftermarket will solve this serious deficiency but do not being trying to rock crawl without the aftermarket parts first. Of course youd need lockers too so that might be a long long time 😂
I was thinking the same thing Elon said it was more truck than a truck I don’t think so this flimsy pack cover will be punch thru and then water will get in plus if you go a sell the truck with a dented and scratched up battery pack how good is this going to be for resale value ? If the truck came equipped with a removable and replaceable skid plate the this part could be easily replaceable I think TFL trucks tested a Hummer EV off road and they scraped the underside of the truck but they said the truck had a skid plate and the engineers said that it was designed to be able to support the compete weigh of the truck 9000 lbs.
Much appreciate the deep dive. Thank You
Wonderful presentation. Lots of good information and no silly talk to waste time.
A Karcher dry ice blaster would be perfect for removing that foam without damaging anything or shorting out.
IRC they ether rented or purchased one last time they did a Tesla battery tear down.
They did and it took forever! But there was a lot more foam. This is nice and cleaned up. Hope they are able to save and reuse that excess.
@@Barskor1 I don't remember the brand, but do remember they blasted with dry ice. It was very expensive as mentioned in the video.
@@PhotoHoag Dip the whole thing in a saltwater bath to discharge it and then add gasoline to dissolve the foam.

AWESOME content! Thanks for sharing
Great info as usual! Thanks for sharing!!
Tom this might be a crazy but with those wafers in the vent ports would it be possible for them to gather 'salt' from sea water when drying out, which in turn stop them from closing?
They really dialled the safety design aspect into this pack to eleven, that's a ton of volume both for side impact and venting.
I'm guessing some of that extra bottom to is rock penetration/pack damage area due to off road.
its definetly not lol!!! the truck is yet to proove any offroad capability
There are many videos of the Cybertruck showing its capability compared to highly modified 4×4's and rock crawlers with impressive performance.
@@carholic-sz3qvdudes always trolling the comments. Tesla bad Tesla bad … 🤣🤣🤣
This is an excellent showcase! ❤
When you put the batteries in parallel 😅, you keep the voltage but allow it output more in terms of capacity and dumping amps.
When you put the batteries in series, you greatly increase the voltage, but keep the amps the same. So 9v+9v is 18v.
@24:35 Suppose you high-center your off-road Tesla CyberTruck and dent the battery skid plate. Who determines if the battery is damaged enough necessitating replacement and I this replacement covered under Tesla off-road use warranty or by insurance?
If this is the future of cars which it is. Then the government needs to take measures to get companies to providing funding for battery recycling like the recycling programs for glass bottles in the 60’s. I know there are programs that can recycle them but there will need to be funding for larger amount of facilities. These batteries are becoming more and more locked down and more impossible to work on individually.
Thank you, great run through
well done guys. keep 'em coming.
Another great video Sandy and Tom! I wonder if you could break off a chunk of thet structural foam and do a.Flamibility test?
Tesla has some great solutions for handling water ingress. Unfortunately that foam is likely make the pack economicaly unrepairable, prevent fire fighter water application to the cells, and hamper efficient recycling.
Then there's the stranded energy issue. In a.breached battery of conventional design dunking the pack remains in brine or sodium bicarbonate solution will eventually discharge all cell groups.
With the pretty green foam keeping water out, all bets are off. At least my bets
good points , its a pity , it looks like will be impossible to repair ,hopefully Tesla has some sort of insurance in place for that problem.
It's designed to be ground up and all the elements are separated then recovered for recycling/reuse.
@@tomnel BS you can't recover anything from destroyed material Not to mention the expense it's cheaper to make a brand-new one. This whole design is throwaway garbage which is okay but they should be honest about it.

Has anyone figured out how to bypass failing cells yet? Its bad engineering to have a single cell produce a full pack failure. Also did they make the inlet coupling more robust such that a crack does not render the pack useless? That was a Model 3 issue and for bouldering it would be catastrophic.
This battery pack is even less repairable than your Apple phone 🤬
Fluid dynamics might be over my head but it wouldn't put me to sleep on Munro Live
Fluid dynamics is a dry topic❤
I appreciate your excellent explanation.
Wiegel looks like an awesome shop. I work in automotive stamping/welding.
Hello! Thanks so much! 😃
Any chance we can get a tear-down of a BYD battery pack. I'd like to see a comparison between the safe western batteries and the more dangerous chinese batteries known for spontaneous combustion.
I wish our politicians at the national level would appreciate and value the level of ingenuity this video shows.
IMO for the USA to continue to lead the world, it needs to value and support more of what we just viewed.
You know who sandy wants to win
@@mattbrew11do you? He strikes me more like a traditional republican.
@@danubiosalas4231 which lands where in your perspective?
The USA leads the world?
thanks for doing this.
Great video! I appreciate the coverage of many details of the pack design. Please do sell the cells, but price them for a profit this time. Perhaps look into different shipping options to lower cost, and double the price if needed.
