"As they grow older they need a little more space." Yeah, me too.
Yes, even my skull seems larger with age!
Ben, you're getting a lot more comfortable in front of the camera! Keep up the good work.
Thanks, will do!
I was a little worried that Munro Live would stagnate after the Model Y teardown series wrapped up, but it turns out I just love engineering porn, and this channel is probably the best out there. The insights we get for free from this channel are highly valuable.
It's great but remember that's it's not for free, the UA-cam algorithm and therefore Google and so Alphabet have sold your attention to the advertisers which you see on the platform - that's the business model. Munro live is great content but nothing on this platform is free.
@@bluetoad2668 true. But then you can just develop the power to literally ignore all ads
Love geeking out with Uncle Sandy and the team. Look forward to every upload! Always learning something new.
Thanks for watching, Zak!
The 52 second intro of the disassembly taking place could easily be extended for many minutes. It's fascinating! Thanks as always, Sandy, Ben and team.
Glad you enjoyed it
7:10 That's not a ribbon cable, it's a flexible PCB
That's what it looks like to me, too.
In the Aero business we used to call them flex tapes.
and its more expensive than a rigid pcb
@@torcek1991 Looks like it's riveted directly to the cell-interconnects with the flexibility taking up tolerances. Not needing connectors at each interconnect probably balances out the cost.
@@ericsandberg3167 it’s amazing how many manufacturing techniques from the aerospace industry they are using to make more efficient EV‘s
Full stop, watch munro...
Hey, Sandy! Can you go over the differences between pouches and cylinder cells. Things like energy per volume, energy/kg, ability to use as structural component, etc?
Higher energy capacity possible per unit means fewer cells Battery weight can be lower but harder to package cells a way that can provide structural support for a vehicle.
There’s this wonderful new tool on the internet called Google but PS was very kind to answer your question.
Well, Tesla's engineers decided against them - but what do they know?
@@psdaengr911 Ive read the pouch-style cells can swell….not when they were old, but in normal use. Is that true
Watch this video:
www.eevblog.com/2020/10/02/eevblog-1340-new-tesla-4680-battery-cell-explained/
I dont want to be toooo harsh, but there are some big gaps in knowledge of these guys on lithium cells.
To suggest they are going to make improvements to these packs but dont understand some basics
says something about the authors.
Two bits of misinformation given in this video:
1. the cells over time recharge themselves chemically.......nope doesn't happen.
If you discharge a cell down to its minimum voltage ( not wanting to damage the cell), you might go down to
say 2.5v......the pack will still have alot of voltage in it after discharge.
If you fully discharge the cells down to zero volts, they wont be re-usable, they will be permanently damaged.
To say they were discharged by professionals? sure guys
2. the rubber mats inbetween cells they said were to cater for the swelling of cells with age.......nope wrong again.
The cells expand contract on each cycle depending on state of charge. Its a constant thing not just after aging.
Very important to keep this in mind in design, if the cells cant swell there will be alot of pressure in that pack.
Its one of the ongoing issues of lithium cell design: how to cater for the swelling. it damages the carbon anode in the
cells causing cracking, hence research towards alternatives to carbon anode layer on the copper.
Also some temp effects on swelling but mainly related to lithium ion transfer as far as I know.
I sometimes find it curious that people want to show themselves to be experts, but in reality they are learning as
they go. Anyone can teardown stuff and critique it, to actually design and build stuff is another matter completely.
In addition to cyclic changes, pouch cells do grow in thickness with age... according to at least one cell manufacturer. They should have mentioned the changes in each cycle, not just aging.
I hit that notification faster than I do my chores.
Cant be that fast then! :p
Me too. I really look forward to the next exciting episode of Munro Live.
Makes Sandy and Ben sound like Batman and Robin 🤣
😂😁
Sandy, you have an amazing team! Thank you for making these videos!
Thanks for watching, Freddy!
Sandy - You and you team are an engineering university! Thank you!
Looking forward to hearing about the new battery tray designed by your team
Industrial design is like cooking " you mix the best of everything " ;-)
It will be Tray Magnifique!
Awesome, Finally the video we've all been waiting for!
Hope you enjoyed it!
Mache-E is beginning making me begin to doubt the overall superiority of cylindrical cells, I can't wait to see your best of best design. Hats off to the Ford team and hats off to Munro and associates.
These pouches are def better and as they learn to get good connections and control swelling they will take over. I personally think they should wire them in spirals to cut down on collectors and bus bars.
I deal with a lot of batteries mostly pouch style but also cylindrical cells in industrial equipment. Seen several thermal runaways and caused one myself. I have a healthy fear of anyone or any machine handling pouches. Give me a good strong can any day.
@@videcomp Amen to that.
@@videcomp Perhaps the foam in between the poach cells does more than just compensate for the expansion. kulrtechnology.com/hydra-thermal-runaway-shield/
@@videcompthanks for the reassurance. I’ve seen the trend is to move away from pouches towards cylindrical or prismatic.
“Batteries from LG with a similar setup to the Chevy Bolt?” Uh, cause for concern right there - a good chance your Mach-E will catch fire or have its DC fast charging capability nerfed in the future, just like Kona, Bolt and Ioniq. No thanks.
Can someone please speak to this? How/If the LG design has changed since their issues?
I agree, that's a pretty good design with a lot less assembly work than a 21700 or 18650 Tesla tray with all the aluminum ribbon cooling paths. Love these videos - you are doing a great job!
Occasional fires a small drawdown?
This can never really be structural, bags are not structural… the case yes but that is extra weight.
Be careful there, Tesla batteries have proven themselves over millions of miles, it's the most critical part of a BEV and it has to be right. My single biggest reason for going with Tesla is the high confidence I have in their tech and the no. 1 part is the battery.
Does anyone else think that Sandy looks more like Albert Einstein every episode?
Don't slam Albert like that. Sandy is a hack! I just watch him to remind me who the dirt bag is that's cheapened American cars to the point of junk. He needs a box of bolts rammed up his back side
He does, but he's not. I wish he'd shave and act his age. He's only 72., my age, and he looks and acts +10 years older.
@@psdaengr911 he thinks young though. Always thinking of ways to innovate. I like that. Long may it continue.
No
@@rzu7120 you need to see an optician 😎
Best automotive show. Period. Munro over Clarkson any time.
It is noticeable that the assembly of packaged batteries is difficult to automate. It is very difficult to ensure the quality of the assembly of the cells. (Based on the experience of Kona and Bolt)
FORD is using OUTDATED pouch LION cells from the Laptop industry , not ideal.
SANDY says Cylinder LION is Superior.
@@markplott4820
Go and talk to Warren.
That was a Tesla talking point. Packagingwise, they're a nightmare which is why Tesla is going to the much larger cell size
Watch this automated assembly of cells to bus bar sheet: ua-cam.com/video/KgN3lVDO_j4/v-deo.html
@@markplott4820 That's hilarious - the 18650 format of cylindrical cells were taken straight from laptops.
Haha, kudos to Sandy for giving due credit to the Japanese. Bob Barker was a filthy plagiarist. Also, I'll take all the intern b-roll you care to throw at me
Lovely understatment from Sandy, 'death can ruin your day'
200k subscribers in 1.3 years, Good !
Love the channel, but you should consider getting a EE on staff that can talk about the electronics from an electrical perspective. Love the assembly/manufacturing perspective but a skilled electrical/electronics engineer to dig into the EE details.
Guys, please! This is absolutely wrong! The thermal compound is NOT helping with the transfer of heat. As a matter of fact it’s more of a thermal insulation than anything else. The reason it’s used is to enlarge the thermal transfer area by plugging all the little holes and imperfections. So the idea is you use it to kinda glue two components together. Theoretically you could create two surfaces so flat and even that the compound would be unnecessary, but it’s too complicated and way too costly to do so.
Not that they are using it here, but isn't there a thermal transfer enhancing compound (based on tire black of all things)? I recall this from an article on CPU cooling.
@@mntbighker well, I am not entirely sure what you are referring to, but in general.
Silver - 429 W/m*K
Copper - 398 W/m*K
Aluminum - 247 W/m*K (most heat sinks are made of it!)
Arctic Silver, one of the better ones, contains a lot of silver. Guess what? 9. Yes. 9.
That’s 40+ times less than pure silver.
Thermal Grizzly crazy paste for crazy money (33 grams for over a hundred euro) - 14.2
This is absolutely right no wonder why it's called a gap filler ! Best versions of it usually deliver around 3 W.m-1.K-1 AND remove any air that's in between the surfaces. So overall better contact than a alu/alu direct contact ...
Very enjoyable. I bet you are encouraging many future engineers/ interns/employees to work at your place. Keep up the great work.
If you turn down the intro music 3-5 decibel, I think it'd be perfect!
no. it was perfect. it was loud enough to give the music its full voice.

Love the explanation with very knowledgeable tesms
“…and keep tipping those cashiers…”
Sandy, you be yourself & don't compromise on things that are important to you.
We love you just the way you are
@@elektrotehnik94 just mentioned the same ... Forget what Kori's is suggesting and keep Munro as it was
Excellent review guys. I am encouraged by what Ford has done on the Mach-E. I hope they can manage to be flexible and act quickly to evolve this and other vehicles. Your comparisons shed so much light on competing designs. I sure hope you sell your upcoming "composite design" I can only imagine how positive that would be for all OEMs. One this is for sure, you are helping advance the development of EV design in a BIG way.
Thats a nicely designed battery pack. Not bad for a first real try by Ford.
Likely an LG design...
They send their batteries out to discharge them ? ? ? Can't assemble a simple resistor bank or even a digital electronic load ?
There may be liability issues.
Yes, but the expertise in handling is what they are paying for. Too easy to have a wire or tab touch something it shouldn't unless you are paying 100% attention and know what can go wrong. It's like defusing a bomb, it's easy to snip wires but knowing which one and what order is the hard part.
@@TechnicalLee
Well, one is a kind of greyish-blue and the other one is a kind of er, bluish-grey...
NICK, Tesla can discharge on site and charge other packs with battery.
Sandy and the team, you are inspiring people doing this. Keep it up 👍
Thank you! Will do!
Are you concerned that Mach-E might face similar battery issues as the Bolt if they are using similar modules?
Nope, the issues might actually come from the bolt management system.
My guess is that the Bolt problem is a bad battery batch from LG. This would explain the failed fixes as GM try every work around that they can to avoid the immense cost of full battery pack replacement. A newer batch of batteries from LG should not have the same problem.
@@johnpublicprofile6261 I am thinking it’s a software or hardware issue with their charging and power control.
Some Mach Es have already gone in for battery replacements. Replacing not repairing. I think Ford either wants whole units back to autopsy, but maybe just doesn't trust dealers to do the repair yet. I'm following this on the Mach E forum. I find it telling that the upcoming Ford Lightning electric pickup is using SK batteries.
@@Miata822 yeah I thought SK was their supplier but they did have that lawsuit so they probably went with LG to get the first batch out.
since when is a flexible PCB less expensive than a FR4 PCB?
A one sided one can be. The process for mass production using continuous fed plastic ribbon requires less material handling than rigid board. Ribbon can be punched and cut to odd shaped with lower cost tooling than rigid board. Flexible boards can connect to directly to other nonplanar components, eliminating added connectors and harnesses.
this thermal paste turns into chalk after 5-6 years...
Same stuff that's holding your home computer cpu to it's heatsink. Do you own computers older than 5-6 years? Mine seem to be working fine.
@@morrisg yes and I change the paste every 6 years, try that on a EV battery :D
Love this channel. The media is dead asleep. The future is here.
Something tells me this video is really gonna blow up now that there is a recall.
"These cells have been discharged already, that's why we can touch them"
That's not why you can touch them. A single cell is only 4 volts fully charged, as long as you don't short the cell or damage it then it's safe enough. A discharged cell still has enough energy to start a fire, so the precautions are the same either way.
"We send them out to have it done, we don't have that capability here."
That also doesn't make sense, I discharged one of these using a space heater (which is just a 9.8ohm resistor) and a multimeter. If you have 30 bucks you have the space heater, and if you don't already have a multimeter you shouldn't be handling a battery.
“A minimum amount of aluminum” Say that five times fast hahah
Seems easy to me...
I failed after 3: "amuminum" 😂
A minimum, a modicum of many mini strips of all alloy aluminum. Try that😎
pronounce it as AL U Min E Um.
that that that that that
Love watching things get reverse engineered
Keep em coming guys, loving the frequent uploads 👌👌🙏
More to come!
This battery construction makes a stack of 18650 or 2170 cells look simple by comparison.
I guess you've never seen a Tesla battery, which has modules (like this) with fluid connections to every module, and layers of structure to hold everything together. There's little difference in complexity.
It seems like tesla with the 4680 cells and cooling system will be a really good way in efficiency standpoint. PS great video
Friday satisfaction and I didn't lift a finger .
That’s a lot of fluid carrying rubber hose, hose clamps & push connectors inside the sealed battery pack. Service nightmare if a clamp or o-ring leaks.
6 connectors for cooling EACH tray ??? color me confused - 6 holes but 1 or 2 quick tube connects. confused.
9:00 After you've separated the cells like that, you're not dealing with voltages high enough to require PPE. I'd still wear basic gloves, but that's only to prevent contaminants.
Yeah. That was a dumbass remark. Even a fully charged module is modest in voltage (around 40V)
As always a great job !!
Thank you so much 😀
Thank you for these videos.
Glad you like them!
@@MunroLive - I really do like them. I have learned to appreciate the simple build quality and dependability of my ICE powered pickup so very much over all of the electronic and plastic electric vehicles currently being produced. Just my honest opinion. I look forward to when EV's really are quality built like some of the older ICE vehicles.
So, wait, if the Mach-E is using the same batteries as the Bolt, will Mach-E's start lighting on fire soon like the Bolts are today? Are the differences in the battery enough to have fixed the Bolt's problem?
Glass molded plastic would be a game changer for battery tray, light but strong.
No way. A tenth of the stiffness, a third of the strength. You can redesign it but will need to increase the pack height by at least half an inch. That's either less batteries, or even less room in the cabin...
Steel and aluminum are good materials. Plastic is not for structural applications (and I'm a plastic automotive engineer....)
Glossed over the leak potential in the battery cooling but not with the motor cooling.
13:00 Hopefully we'll see compare/contrast analysis of "flat packs" vs "cylindrical" packaging. Flat packs seem obviously more efficient from many points of view.
Those being?
@@rogerstarkey5390 Among others, fewer parts. Additionally they can fit into complicated spaces. You think differently?
Although "flat pack" is descriptive, the standard industry term is "pouch cell".
I'm curious - are there any built-in protection features at the cell level? Overcurrent, over/under-voltage? Or is that redundant when you have a sophisticated BMS managing the whole pack?
Great question, my understanding is that different cells can degrade at different rate, so they need smart charging down to the cell level. But I have no idea if anybody actually does that.
Same concern since the battery is similar to Chevy Bolt and the multiple Bolt fire caused by charging. The Bolts that had battery fire issues were from 2019 and earlier so let's hope Ford is up to sniff with their software and hardware .
Cell voltage is always the same for the ones in parallel. So never at a single cell level but by rows of 2 here on these modules. You cannot charge the cells independantly. Current flows in series from the tabs, and only time with deep discharge or high charge can rebalance things. The BMS can track this, but cannot correct it independantly. Just imagine a bath tub with multiple cavities that have slightly different levels. It's only when you reach the top that you can balance all cavities...
Just like every other EV, the BMS handles the cell at the lowest parallel group level; individual cells in a group function as a single larger cell.
Anyone else bothered by the possibility of a piece of road debris striking the bottom of the cooling plate and deforming it or worse getting punctured. I don’t trust of the Mach-e has enough protection there
fully discharging the batteries and ruining it is so silly. those modules are only 22v each as shown in the video... not a big deal at all. I work with the 10s modules out of the bolt all the time.
Given GM and Hyundai Motor Group's recent issues with LG Chem pouch cells, I'd be seriously worried about the long term safety of this battery pack. Ford needs to do some serious testing on these cells to make sure they aren't going to cause vehicle fires as they have in Hyundai and Chevy's EVs.
They don't care, it's a tiny portion of their business.
Can't wait to see this battery! Wow.
I keep thinking about the multitude of coolant connections nestled into a high voltage environment......
i so understand why ford battery tray is the way it is because they still dialing in a tray that can go into all of there different vans/cars/SUVs/crossovers. with Sandy help they can become the number 2 player in the future of cars and trucks. I see we will have the small hypocars brands. then we have a tesla with pushing everyone else like the Iphone. then we have the Android of cars the Rivian and Ford. like we used to have honda and toyota
I think the impact from the Ford F-150 Lightning is going to be way more impactful than the Rivian.
Yeah...cuz Sandy is smarter than the Ford & engineering engineering collective.
Very informative video as always, thanks!
The cooling system looks better than anticipated... Will you please weight all the bus bars and balancing cables? It will be interesting... :-D
@w4csc stop talking nonsense, its not a super hot/high pressure piping system compared to ICE cooling.
Regardless, there must be a better way than using all those individual connectors. Clearly the future will not look anything like this. I'm thinking the cooling solution may end up looking like a giant laptop CPU cooler. But that's just a paper napkin idea.
@@mntbighker by using things like gallium the electronic may be made way safer and reliable
Gallium? Are you an idiot or a PhD?
For their first crack at manufacturing an EV it seems like Ford did a really impressive job.
Ford Focus Electric: I guess I don't count then 😥
Ford Ranger Electric: They never counted me 😉
Ford has been making vehicles for decades and hybrids for 15+ years. They know what they are doing. You can tell serviceability and recyclability are considerations in their designs.
JOE - FORD did not build the car, LG did.
@@markplott4820 Funny that. The factory in Mexico has Ford signs and logos all over and they are Ford employees.
@@MarkLLawrence the ranger electric wasn’t a serious effort. I compare it to GM’s EV1. They were mostly leased, then returned and destroyed. Ford even stopped listing them in our repair manuals. It’s like they never existed. The Focus was a decent effort though. They didn’t sell well. But they’re out there. And ford still publishes the service manual. So I actually consider them to be the first REAL effort. The Mach e seems to be the first that they actually WANT to sell
Thanks Sandy and crew, great breakdown!
With ya Kevin, love ya driving vids...
Our pleasure, Kevin!
@@EVBud69 thanks :) appreciate the support
Given the Bolt was just recalled *again* for battery fires, it may not be a good thing this is so similar to the Bolt's!
Just read a video title today (didn't get around to watch the video yet) and it seems it's a manufacturing defect from LG, so construction method is unrelated to the Bolt fires.
No fires with these cells
"should I do the Kori's thing" NO you shouldn't, grow by merit, people loved it more when you asked us to tip those cashier's...
Has Munro Live provided any theories and thoughts around the Norway reports that Mach-E EVs are overheating going downhill? How about the various news stories around Mach-E EVs being "Bricked" due to software updates. If the Mach-E uses -- seemingly -- the same LG batteries as the Bolt, shouldn't he address the fire defect that GM is currently managing through? Or is he mainly focused on traditional mechanical engineering / door gap fit and finish?
Does Munro still recommend this EV?
IDK about Sandy but I wouldn't want one. As a rule it's not a good idea to be the first to buy a new product. Most honest engineers will secretly agree.
No worries for the machE batteries. The cells are built in Poland in the same factory and inner design than Audi ETron, Porsche Taycan, Jaguar I pace... None of them catched fire.
The module construction is similar to the Bolt EV, but the cell is far better constructed.
@@harrychu650 you're right but nothing due to the cells to my understanding. Issue with voltage peaks due to the weak on board charger trying to do 110V -> 800V. No fire in Europe where it did 240V-> 800V but I may be wrong....
Similar to the Bolt prismatic battery cells? Uh Oh...
Clearly, these are LG pouch cells.
Prismatic cells look different, and the modules look like 12v battery.
@@markplott4820 sorry I meant pouch...
Oh oh what. Neither car has any issues with these cells.
Very interesting to see how different manufacturers go about producing a similar product.
Very FEW can copy Tesla, except RIVIAN and LUCID.
all other LEGACY OEM are using OUTDATED Lion pouch battery from the Laptop industry, not ideal
I was a bit surprised at the thermal paste. With CPUs, modders sometimes go to great lengths to lap their CPU and heatsink to a mirror finish. Paste should be applied in a very small amount as the goal is to maximize the surface contact area. Perhaps the thermal paste applied to the battery pack just isn't as delicate an application? If we sloppily applied paste and did not have full contact between a heatsink and CPU, the heatsink would perform horribly!
A laptop CPU has a thermal flux comparable to a nuclear reactor. Apples and oranges. Let the grownups with engineering degrees be smarter than yourself
Lucid uses the same dimple covered cooling plate design
OEMs better be watching Munro Live! Great opportunities for engineers to learn about their own products. The tear downs and analysis by Munro cut right though the silos that engineers are stuck in
Nope, they don't need to watch munro, they can improve their design in house easily.
Curious about the need for the longitudinal bolts. If the battery end plates are properly processed they are weldable, thus only using a couple of metal strips on the sides.
You do need a bit of preload to hold the assembly together. I looked at plates before but aluminum bolts are cheaper and lighter.
@@Mark-gw4iy the end plates that I see on most batteries are structural and certain they are preloaded and all have to contend with thermal expansion adding more stress.
i think this pouch format should have shielding or aluminum housing for each cell. It makes more for a more expensive cell but simplifies battery pack design and improves physical protection and cooling.
There is an aluminum plate against each cell for cooling, which is shown and described in the video. There is no reason for more housing around the cells; the polymer stacking frames and the metal battery case do the job.
@@brianb-p6586 much has happened and i've learn more since and the Chevy Bolt has a terrible battery problem and will not be built in till the last week of January 2022. The BYD Blade battery has safer, weaker LFP battery cells but still has shielding for each cell.
@@zodiacfml "shielding for each cell" in the BYD "Blade" battery just means that they are metal-cased prismatic cells, not pouch cells. BYD uses the cell case as structure in the Blade pack design, so one very long cell spans the width of the pack, supporting itself when packed against other cells. It doesn't do any more for cooling than the plates sandwiched in the pouch stack by LG. If prismatic cells are used in the same size as pouch cells - so there is no structural benefit - the extra cell container is just extra weight and cost... which is why that sort of construction is now rare.
I really like the cell design with respect to the thermal management but much like the cooling system, they have way too much copper busbar in there. Like they didnt even attempt to plan a better option...
I think that's all you can do when your packing modules like those. Unless they were designed to be connected corner to corner like a string of 9 volt batteries. I should patent that LoL
Yep i agree there's too much. However, need to be careful with copper section to avoid heating by joule effect with quite some amperage
His sidekick is nervous, hopefully he'll get over that with practice.
Difficult to present seamlessly like Sandi does, but he was probably the same way when he started.
I always thought that fully discharging a lithium battery is damaging to the battery.
I think they are intentionally destroying them, not planning to reuse them. Which is kind of sad, but I guess this is what they normally do when they take a car apart?
@@geraldh.8047 Nothing that enters that shop ever operates again.
These LG pack look like what is used in some PC and hobby electric drones, planes and cars they tend to swell up during high discharge and the Tesla Panasonic 18560 cell seem to keep it shape under many cycles of discharging. I wonder if those LG Pack tend to swell up as they get older?
They swell up to 11% of the thickness at end of life. if you get the right amount of pressure with with foam the end life swelling will be about 9% . Abuse the cell it will be a lot more
Well done, guys! I wonder, why they put the cooling plates at the bottom of the packs. Wouldn't they be more efficient at the top as heat raises and the cold sinks in the pack?
heat isn't a fluid - it doesn't rise or fall. Cold doesn't even exist - it's just the absence of heat. Hot air rises compared to cold air, but the heat transfer in the battery is by conduction (exchange of heat through stationary materials) not convection (movement of heated fluid such as air). Putting the plates on the top wouldn't make any difference to the heat flow.
A video on the Lightning will bring another 200k subscribers in short order.
Unfortunately, the Lightning is a POS truck.
@@markplott4820
Glad you liked it!
It was interesting to see that LG's packs are using the same type of cells as I have used in electric model aircraft, while Tesla continues to use individual cells like 18650s.
Looking forward to seeing your Best of the Best Battery Mach-up. Pun intended!
Really enjoy these videos - progress is made in small measures over time.
Would you like fries with that?

Hard to remember what life was like b4 discovering Munrow, such fascinating content
Every 'like' is doing something to keep cash coming in the Munro door. Great to see that your videos influence staff at Tier 1s and OEMs to send you work.
Plates and the trays
I would imagine that these companies have patents on almost every aspect of their designs, so it will be interesting if you take the best ideas from each to make a better, cheaper battery. Better factor in some significant royalty costs for that bad boy.
It seems like every manufacturer except Tesla goes for pouch or prismatic cells. It will be interesting to see how this shakes out in the future, because they are very different approaches with big implications for manufacturing, cooling, and presumably cost.
if Pouch or Prismatic cell = DEAD LAST, which is why RIVIAN can get 400 miles on 2170, and LUCID is also using 2170.
The MIC Model 3 SR+ uses CATL LFP prismatic cells. Already available in many countries. That LFP battery soon to be available in USA in Model 3 I believe. It is a less energy dense & heavier pack than the equivalent NCA 2170 round cell battery, but is cheaper, safer, uses no cobalt or nickel, has similar performance and LFP chemistry inherently has longer life. That specific chemistry has improved a lot in the last 3 or 4 years and may well take over as the dominant battery type in affordable EVs. Even Tesla's not yet released 4680 battery may end up with a LFP version.
@@adrianleitch6996 - its a good Solution for a RWD Short Range car , but batteries are too Heavy for a Dual Motor or Performance model.
those, work better with Nickel cells.
It seems so odd that they made the 1st bay slightly smaller than the other 4. I would have thought making all five identical would have been easier and a little extra battery wouldn't hurt range.
And there's empty space in that bay as well
The pack tapers at the front a bit so the vehicle structure can tuck in for the front wheels. Many packs have a few modules of a different size to make the packaging work, and to reach the desired total cell count.
Thank you
You're welcome
Fascinating.
More hidden rubber hoses with multiple areas to leak or fail. With all the rubber hoses and connections in the Mach-E, Ford should buy their own rubber hose manufacturing factory.
Do you have the same concern with the many fluid connections in a Tesla Model S or X battery?
Best Subscribe Pitch Ever, "Save me from Corey's Wrath"! But we all know that Corey can be appeased with a bottle of Beer!
feels like way to many pipe connectors for me each one is a leak opportunity
I thought so too but the whole package will not move much so I don’t think it’ll be a problem.
Seeing this makes me extra appreciative of what Tesla is doing with cell to pack architecture! It’ll be revolutionary
In Tesla's DGAF engineering way, it'll write off the car more easily.
I got my signed bumper sticker in the mail yesterday. Looking forward to when you guys get the plaid
Yet another great and highly educating video! Could you please elaborate further in comparing this type of batteries (being so similar to the Bolt’s, seem a bit out-of-the-shelf, and someone else already raised the problems that these batteries have been experiencing) to other types, e.g. the cylinder ones from Tesla, which I understand you very much like, and BYD’s blade type ones, which they claim to be highly performing and durable? BYD is btw approximately as vertically integrated as Tesla, or even more so, and is probably backed by the Chinese State to come up with highly competitive product/price offers - deserves being systematically monitored I would say… Thanks once more for the great job - and also for having reached debt freedom by the way!

Hey guys!
Thanks a lot for another interesting and educational video!
About the battery pack and refrigeration system, is it then feasible for you to study the problems in the Bolt leading to the 3 recalls so, now having the similarities found in the Mustang, discern whether or not we may start to find fire risks elevate for the Mustang also through time and volumes?
Should I do the Correy thing? 😂😂😂. Thanks for keeping it real Sandy!
The Chevy Bolt was just recalled over concerns of LG battery fires. Not good for the Mach-E!!
No worries for the machE batteries. The cells are built in Poland in the same factory and inner design than Audi ETron, Porsche Taycan, Jaguar I pace... None of them catched fire.
The module construction is similar to the Bolt EV, but the cell is far better constructed.
Genuinely interesting to see, let’s hope Ford have the charge management cracked and haven’t followed GM into the overheating and fire issues they have had/are having.
So it's basically a larger Bolt design. Far too many parts, assemblies... the MEB pack looks simpler with its extruded aluminum modules. However, these extruded modules have one additional layer of thermally conductive gap filler, an inner insulation that's coated, and welded end caps making it tough to disassemble. So it's a trade off, clearly!
Maybe Sandy can record a "please like & subscribe and tip your cashiers" piece that can be part of the outro for all videos.
Doing it fresh in every video has a higher response rate.
