@ Munro Live: 13:16: These are also called RIBBON bond. Wire usually refer to circular cross section. Also the different thickness of these ribbond might be due to the different thickness of the positive tab of the cell relative to the negative shoulder on the top of the cell that is different thickness. Typically 21700 cells like that have positive tab of 350 to 500um while the nickel plated steel cell can is 250-300um. This thickness difference in the ribbon bonding might be to optimize the ultrasonic bonding and match bonded thickness. Or, the temperature dissipation ( related to the fusing voltage anc current) from the ribbond to the negative is different than on the positive due also to these different cell tab thickness between negative shoulder and positive tab. The thinner negative might heat faster than the positive tab and shift the fusing current value related to the heat dissipation into these so increasing the negative ribbon thickness would compensate and make the fusing power ( or voltage or current) identical for both negative and positive.... or... Both connections are ribbon bonding but only one is for fusing and one is only a connection bridge. Why having two fuses in serie.... and loose additional power into heat ...
Yes, its a flat ribbon and not a consistent diameter wire. Essentially the same thing at these sizes, with no functional difference. We have been using ribbon in discussions, but "wire" was said.

@@nickdunn248 No. They were talking about doing that with 4680s, but for now they have a variety of different cell chemistries each with their own cell form factor and pack architecture.

@@andrewk8636teslas structual batteries are unrepairable as well. But Tesla undestand that if you make them unrepairable you have to make them cheap, which is what they are going for. The Lucid battery is unrepairable AND silly expensive to build.
Cell level protection is probably the purpose of those small connections from each cell. Cells can fail short which would cause great current inflow from the other parallel connected cells. For example the Tesla Model 3,Y have 46 cells in parallel to make one group then 96 of those groups.

Tesla , or many others, could have higher energy density. The real issue is cost / Kwh. and what is practical. This is one of the reasons Lucid is so very expensive.
1. How modules are installed over structure? Bolted or some adhesive used? 2. What is the material of battery pack module? Is it Poly Amide + GF? 3. What is the provision of venting provided in module as the cell bottom is at the top? 4. Does it have centralized BMS or distributed BMS architecture?

Does it? I see different strengths and weaknesses, so I suppose it might depend on what you personally value. The HUMMER EV definitely has better BMS and busbar integration, but the Air probably has the cleanest, best cylindrical cell pack I've seen overall.
Really ingenious & effort intensive product design. Honestly the only company who has what I’d consider a very worthy competitor to Tesla’s model S & X lineup.
@@markplott4820 I’m talking purely in terms of vehicle design. Part of the problem with lucid is that they’re not as well known & haven’t been around long enough to become well established or build a charging network. In terms or raw specs & packaging lucid air is about as good as premium electric sedans get
@@timothy705 - FALSE , Loocid motors was founded more than a DECADE ago as Ativa , and with LITTLE progress. TESLA model S PLAID is already the BEST LUX sedan on EARTH. and the Unplugged Performance APE-X takes it up several Notches.
The problem is in the US there is only a tiny proportion of the EVs manufactured being sold. Where BYDs are available they are head to head or in many cases outselling Tesla. Furthermore their blade cell single module battery (126S1P) is a completely different take on traction battery design that is light weight, low cost and proving extremely reliable.
Well you are watching the free version of the tear down. To get the details you are asking for you do realize they sell complete information. It is at your beck and call, you have but to contact them and request the information. You do have to pay for it though remember this. I do not begrudge them this financial hook. It means you've been baited by a giant commercial is what I'm trying to tell you. You complaining about lack of content in the commercial is just an interesting thing for me
@@deantoth Kind of agree, but I follow the channel till the begining and some videos are better built than others. Considering Lucid is somehow prone to interest people, raising content quality should bring more viewers. I am not at all a report buyer, just an engineering amateur.
what is the adhesive used between the cooling plate and the cells? It needs to be an electrical insulator to not connect every cell in parallel through the aluminum cooling plate, as well as have a good thermal conductivity for the cooling plate to be effective.
Thank you guys! I would think that bigger packs should Always be able to achieve higher volumetric efficiency, considering the ratio of battery pack support system vs cells/modules?
Unless the cells are packed extremely tight in the module any vibration could cause the wire bonds to fail over time. Causing cells to drop out from broken bonds and not cell failure. No potting compound seems like a miss.
I think they mentioned that the extruded container the cells go into.. holds them in place.. I think at the ends. And they mentioned it may have engineers reconsider if they need the potting material or not. The cylindrical cells are pretty strong structurally overall.. as long as they are held tightly at the ends I don't think they would move.
Regarding the Bus Bars: i wonder if when you nest the small ones inside each other if they would fit inside the U of the huge bus bar? implying that all Bus Bars in the vehicle are maybe cut from one Sheet for minimum waste..
What does Munro do with all of the battery packs that's torn down? I think by now you could build a battery storage for the facility with it. It seems wastful for it to sit around on a pallet or shelf.
interesting video. But I feel these are biased towards tesla with each detail of this pack being critiqued with guesses of how it can be bad without real engineering proof.
With some flexing and aging, wouldn't this bonded-aluminium-fiberglass mix allow some opportunity for water ingress? I kind of prefer a welded case (Tesla) or stamped metal sheet solution (GM).
Q: With some flexing and aging, wouldn't this bonded-aluminium-fiberglass mix allow some opportunity for water ingress? A: maybe...? cause nothing is 100%, but by the time that occurs you would've already long depleted the useful life of the original cells and would likely have a MUCH BIGGER PROBLEM to focus on.
@@BatterVswithAntonio that makes sense for preventing thermal runaway, but I wonder if those dividers could be engineered to do both. Something like a thin copper sheathing over the thermal brake.
@@kevindavis8143 metals are electrically conductive, defeats the primary purpose, I've seen some thermally conductive polymers and have suggested them in these cases.
@@boostav Usually used for thermal conductivity to thermal, thermal and electrical isolation, or vibration/shock effect reduction. As to why Lucid isn't...well, pouch cells don't? Can't really think of another reason. It is "atypical", but I can't be sure if its a good or bad "atypical".
Pack recycling (and repurposing in after market) needs to be reviewed as a criteria. The failure mode of a pack is that some number of cells will drift over the pack product lifecycle. These cells (out of many many cells) will either increase in internal resistance or not maintain a balanced charge relationship with their adjacent cells. Stated another way - eventually all cells will not act in exactly the same way with regard to charge/discharge. That said these are perfectly good cells for other applications - like home power storage which has a different charge/discharge profile. Imagine retiring your pack to your powerwall - good reuse. The other failure mode that needs consideration is thermal related degradation. The lesson learned on the Prius - the first mass market car that started the revolution - was that center cells which received less cool air tended to fail first. The lesson learned in both of this empirical data is that the granularity of the BMS and the cooling system are critical to battery life duration. Given the volume of this tech its plausible both these nits could be addressed. Especially if ALL manufacturers cooperate to create a non-proprietary solution for the common good.
Prius is a hybrid so no it didn't start this revolution. It also did not have liquid cooling which is the reason why you saw those failures. Being able to swap out modules is irrelevant as being able to swap one in that is in sync with the rest of the aged pack is a fool's errand. It is bound to fail again.
@@boostav I'd say the Prius deserves it's place in the EV revolution, yes it was a hybrid but it drove as an EV and that gave the mass-market a taste of what was on offer. The OP mentioned battery cooling, the Prius did have this, air cooled using a centrifugal fan. And his point on recycling battery modules is right, second-life use is possible with separate 48v modules, possible with BMW/Leaf/early Tesla batteries, but not with Tesla anymore.
@@boostav - Was not inferring swapping a failed pack back into a car - I was referring to alternative markets. Look up B2U storage solutions as mentioned on Matt Ferrell's channel th-cam.com/video/gKSmIqGvZR4/w-d-xo.html That said - there is a big business for repairing a failed pack. They pull the good modules out of a donor failed pack and replaced the bad modules in another failing pack. Its been very successful and lucrative for those doing it. This of course only applies to serviceable packs. There seems to be a move away from that with some newer designs that are not servicable but it was a very common thing to do. And why not? Let's be clear, a battery cell is just like any other battery cell. With proper handling at the cell level they are very low voltage and perfectly safe. And as noted - the Prius, although hybrid, was the first electric (but not all electric) vehicle to capture mass market. It changed the perception about electric as people saw the incredible fuel economy and extended product life with most Priuses going over 300K miles before any major service. Arguably the GM EV1 was the grand daddy but of course it was not available (quite deliberately) in any volume as the documentary notes. Your point about liquid vs air cooling does not appear empirically to have merit as the same "drift" phenomena has been seen on liquid cooled modules. Its just chemistry and probability. With thousands of cells per pack maintaining uniform charge/discharge characteristics over extended life is just not possible. Thus the 80:20% operational envelope technique and active cooling to reduce the stresses that would exacerbate the drift. Toyota, in the Prius, was the first company to do this and to their credit there are Prius packs, 20 years old, still on the road and performing beautifully.
Interesting comment on potting. I can see how the Air pack might not require it given the cells are fixed axially (by the busbar on one end and the cooling plate on the other). Essentially, Lucid's design strategy for cooling and linking the cells might have a side benefit of allowing them to omit potting. It definitely gives them a competitive advantage over other automakers who are still using cylindrical cells.
@@BatterVswithAntonio Oh, I wasn't thinking about the thermals, though I have seen people state that thermals is also a reason for potting. However, my understanding is that potting is primarily used to prevent cell vibration and shock while also adding an insulating layer (that's the reason I'm using a form of "potting" for in the prismatic cell pack that I'm building, too). If Lucid is also only using potting for vibration, shock, and electrical insulation, air gaps with strong axial attachments should serve the same purpose, which would allow them to omit the potting material altogether.
Imagine they'd make a version with 20 modules, where the two in the rear footwell can be slid to the left or the right to offer nicer comfort for one rear passenger. A lot to ask, but it would be nice to be dynamic rather than fixed, so the VIP passenger can decide where to sit.
Batteries need not just power connections but liquid cooling. Having slidable modules would make that a lot trickier and you would eventually run into leakage problems since you'd have to use flexable hoses, and those will eventually age out.
@@wizzyno1566 I agree, good things are just not common in cars. It totally can be done though. If Lucid can given a super slippery sedan big cabin space AND a huge frunk and trunk, they COULD do this. But I'd rather them breaking the trend and just do a wagon version already. "But, manufacturing costs..." doesn't apply, wagon buyers have been paying extra since day one. With a smile. To the point that Volkswagen, Skoda and Volvo even discontinued sedans. The 18 module RWD wagon would sell like mad. Imagine the hauling capacity on that one. Would they even expand the frunk for RWD?
@@Cloxxkialmost anything CAN be done. But SHOULD it be done? No. COULD it be done in a cost effective way? No. Will the complexity cause more safety and reliability problems? Yes. Its just a stupid idea. And "but manufacturing costs" ALWAYS applies. Its just a question as to what extent. Or we'd all be driving bugattis. Theyre already losing massive amounts on each car. They need to stop doing that before they start doing moronic pointless shit.
A: similar to the technology used by both the Death Star and Rebel Base Hoth in Star Wars, an ENERGY FIELD is projected just beneath the vehicle. "this Field is strong enough to DEFLECT any bombardment..."
@@markplott4820 They've not broken promises to the levels of Tesla yet though, and they've been incorporated for quite a while. Seems a legit company to me, the engineering efforts for sure are, making every other brand just seem lazy engineers who don't care about user experience. Their software is the least refined, but that's a matter of time, good software has been achieved by others already at least. What Lucid does with packaging, was only accomplished by them. Mercedes and BMW are just utter buffoons in that respect. Much longer cars, same cabin space, less cargo space, no frunk at all. Lucid's is huge. Range better as well.

Every part of vehicles sold to the public should be serviceable. It would be nice to see laws passed to make non-serviceable battery packs illegal. I don't know why the general public has gone along with thinking it's okay to buy vehicles built like this. Price wise it would be the equivalent of buying a gas vehicle that an owner cannot service the engine or transmission. Just run it until it dies. That's basically what we have here with current EVs. Disposable vehicles, sorry, more expensive disposable vehicles. If it was sealed and waterproof, I could maybe understand. But since they are all sealed for no reason, besides wanting to prevent someone from easily opening up and changing out a single cell that went bad I don't think anybody should be supporting manufactures that build like this on purpose.
… for batteries with liquid electrolyte- do you think it’s possible to construct the batteries so that the liquid electrolyte could circulate in a coolant system, in order to kill two birds with one stone? Just curious..
I was very glad to see the thermal isolation between cell rows and especially a pressure relief per module. This will greatly reduce the likelihood of a catastrophic 'thermal event.' Yes, plate cooling the anode end has a shorter heat path than side cooling. I was disappointed to learn that these packs are not serviceable. EV makers should make an effort to allow repairs to their packs. To my knowledge only Ford and GM are intentionally making cells or modules replicable today.
re: "I was disappointed to learn that these packs are not serviceable." well they're "serviceable" just at the factory, so not by "shadetrees" and "hacks" who might get their dumbasses electrocuted because they don't know proper safety procedures, and think playing with HIGH VOLTAGE is akin to playing with a "toy".
@@phillyphil1513 In the recent WSJ interview CEO Rawlinson stated that Lucid's battery modules were specifically designed to be usable for "second life" applications.

Hi Sandy, what do you think is the difference between legacy auto manufacturers electric vehicles and Tesla electric vehicles? I will give you my opinion after I hear your answer.
The engineering prowess in the Lucid battery pack is so evident compared to the Hummer's. Since cost per vehicle is difficult for Lucid right now, I wonder if the teardown has reflected the high cost at all. Could the adhesives and composites have difficulties around lead time or something vs steel/aluminum?
Much of Lucid's cost today is driven by outsourcing parts. As their factory expansion comes online later this year and early next, more and more processes will be moved in-house.
I think Tesla has different chemistry for their 2170s going into the US performance model 3/y compared to US long range. The anode has 100% natural graphite and thinker electrodes. Uncertain about the cathode. So not only Lucid does this.
I have a feeling the lucid components battery, motors, etc) will be the only commercially profitable aspects of the company. Until they can build something with all this engineering in the 50k range and the 80k range, I don’t think the cars will be commercially viable.
Pretty disappointed that this pack is not serviceable. Peter Rawlinson said that their pack was semi-structural because it offered more advantages than disadvantages compared to a fully structural pack like Tesla's 4680 pack. But if serviceability is not one of those key advantages, than what's the point? This pack must be significantly more costly to manufacture than Tesla's and is probably another big reason why their cars are so costly to make.
It's just the way for evs. Look at the teardown of the nio et7 pack for fun on here. Just as hard as the tesla 4680 pack. 😀 The modules are to hard to rebalance and keeping everything dry&re sealing it correctly in the field is an issue. Just look at the clean rooms required to make the battery cells to begin with. 👍🏻
From the numbers I've seen, the first 4680 "structural" pack Tesla put into production, wasn't a lighter solution than the 2170 normal pack. Just when you bolt it off, you also get part of the interior to follow along out. I think I'd rather have a NIO pack that can be robot swapped in 6 minutes, be it for swift travel or maintenance.
@@Cloxxkihaving thousands of swappable batteries in China might be OK , and a few places where Real estate is a premium- condos and Apartments but that ties up a lot of CAPITAL, and the batteries limit the models they can be used on, and the Swap stations will still need the HV and HiAmp Electric infras.
@@Cloxxki it’s just not scaleable to millions of cars. NIO will always be a niche player. If I have a new NIO, why the F would I ever want to swap for an older battery?
@@GET2222 If superchargers were scalable, then NIO swappers are just as well. They're no bigger than 4 to 8 stalls? Storing various types of packs will be a challenge for sure. Perhaps NIO will phase out lesser packs and give early buyers a free upgrade. Each recharge philosophy has its limiting factors.
That's only partially true. Look how complex modern CPUs and GPUs are. Yet, comparatively, they are insanely cheap. It's all about the manufacturing. If the demand is there, they'll find gains in various places to help drive the cost down.
@@isserdigan2835 it's not about the price point at this time really, they charge 180k for a car, but it costs them hundreds thousands more to build one thus making them lose hundreds of thousands of dollars in each car sold. Whether they are going to be able to solve this or not, we will see.

Does it? I see different strengths and weaknesses, so I suppose it might depend on what you personally value. The HUMMER EV definitely has better BMS and busbar integration, but the Air probably has the cleanest, best cylindrical cell pack I've seen overall.
I think I could have designed a better battery than GM in a votech welding class in 1989.
Really ingenious & effort intensive product design. Honestly the only company who has what I’d consider a very worthy competitor to Tesla’s model S & X lineup.
its no Competition , MODEL S outsold Loocid by 11:1 .
Loocid has a DEMAND problem, and are unable to SCALE.
@@markplott4820 I’m talking purely in terms of vehicle design. Part of the problem with lucid is that they’re not as well known & haven’t been around long enough to become well established or build a charging network.
In terms or raw specs & packaging lucid air is about as good as premium electric sedans get
@@timothy705 - FALSE , Loocid motors was founded more than a DECADE ago as Ativa ,
and with LITTLE progress.
TESLA model S PLAID is already the BEST LUX sedan on EARTH.
and the Unplugged Performance APE-X takes it up several Notches.
The problem is in the US there is only a tiny proportion of the EVs manufactured being sold. Where BYDs are available they are head to head or in many cases outselling Tesla. Furthermore their blade cell single module battery (126S1P) is a completely different take on traction battery design that is light weight, low cost and proving extremely reliable.
Lucid is the luxury brand of EV. I hope they success and make cheaper ones. Cheaper I mean, half of the current price haha
You get what you pay for.
" Scale is hard" said one who had to sleep on factory floors.Go Tesla🚀😂..🛑🛢⛽
They have the proverbial mountain to climb when it comes to being a profitable company
When you design something this complicated it’s going to be expensive. Hence the reason they can’t scale.
Yeah you dont get cheap Mercedes.. smh.. they are priced as such
Thank you guys. Some desassembly photos so as compared competitors modules would have been nice.
Well you are watching the free version of the tear down. To get the details you are asking for you do realize they sell complete information. It is at your beck and call, you have but to contact them and request the information. You do have to pay for it though remember this.
I do not begrudge them this financial hook. It means you've been baited by a giant commercial is what I'm trying to tell you. You complaining about lack of content in the commercial is just an interesting thing for me
@@deantoth Kind of agree, but I follow the channel till the begining and some videos are better built than others. Considering Lucid is somehow prone to interest people, raising content quality should bring more viewers. I am not at all a report buyer, just an engineering amateur.
what is the adhesive used between the cooling plate and the cells? It needs to be an electrical insulator to not connect every cell in parallel through the aluminum cooling plate, as well as have a good thermal conductivity for the cooling plate to be effective.
Thank you guys!
I would think that bigger packs should Always be able to achieve higher volumetric efficiency, considering the ratio of battery pack support system vs cells/modules?
Was the gas in the battery pack determined. You don't need silicone if you use a thermal transfer gas.
Unless the cells are packed extremely tight in the module any vibration could cause the wire bonds to fail over time. Causing cells to drop out from broken bonds and not cell failure. No potting compound seems like a miss.
I think they mentioned that the extruded container the cells go into.. holds them in place.. I think at the ends. And they mentioned it may have engineers reconsider if they need the potting material or not. The cylindrical cells are pretty strong structurally overall.. as long as they are held tightly at the ends I don't think they would move.
I wonder if their additional unknown parts that come out of the same sheet stamping making the large bus u bar part relatively efficient.
Regarding the Bus Bars: i wonder if when you nest the small ones inside each other if they would fit inside the U of the huge bus bar? implying that all Bus Bars in the vehicle are maybe cut from one Sheet for minimum waste..
never mind, at the end of the video i saw both again from a diffrent perspecive, and it very clearly doesnt fit this way...
I wish you guys showed the actually disassembly part more often.
Nice
Do you have pictures of the BMS PCBAs? What type of ICs are they using?
I read that as 'Lucid "Air Battery Pack"' and thought... holy cow, last week it was LFP and now it's only air!
What does Munro do with all of the battery packs that's torn down? I think by now you could build a battery storage for the facility with it. It seems wastful for it to sit around on a pallet or shelf.
interesting video. But I feel these are biased towards tesla with each detail of this pack being critiqued with guesses of how it can be bad without real engineering proof.
I would have loved to have seen more of the Lucid teardown. Why is Munro showing so little of the interior and other parts of the car?
Munro makes the living by selling this information to the other manufacturers. If they give it all away they can’t sell the unique information.
Calm down, it’s coming you know every TH-cam has milk it for viewership, if they show you everything all at once they loose out on ad revenue. 🤣😂😂
Buy the FULL report for $500k.
Customers pay good money for their detailed reports. TH-cam and merchandizing, not so much.
Patience my Grasshopper😂
Irony here is 99% of the people watching this have no idea what they are talking about (including myself) but it’s still fascinating to watch 😂
Haven’t watched this yet but I hope they calculate and reveal the actual capacity.
18:47: they use bottom cooling instead of side cooling then?
top cooling, not bottom... but yes, they are cooling (or heating) one end of each cylindrical cell, rather than a strip along the side of each cell.
God
Bless
Good
Luck.
With some flexing and aging, wouldn't this bonded-aluminium-fiberglass mix allow some opportunity for water ingress? I kind of prefer a welded case (Tesla) or stamped metal sheet solution (GM).
Q: With some flexing and aging, wouldn't this bonded-aluminium-fiberglass mix allow some opportunity for water ingress? A: maybe...? cause nothing is 100%, but by the time that occurs you would've already long depleted the useful life of the original cells and would likely have a MUCH BIGGER PROBLEM to focus on.
With the amount of adhesive on these...still not likely to leak, other things could go bad sooner.
@@BatterVswithAntonio thank you! Amazing work you and Munro team are doing! 👏
I wonder if the serpentine module section dividers are working as fins for the cooling plate, expanding the surface area.
entirely thermally insulative
@@BatterVswithAntonio that makes sense for preventing thermal runaway, but I wonder if those dividers could be engineered to do both. Something like a thin copper sheathing over the thermal brake.
@@kevindavis8143 metals are electrically conductive, defeats the primary purpose, I've seen some thermally conductive polymers and have suggested them in these cases.
@@BatterVswithAntonio Can you elaborate on the potting? Why is Lucid the only one doing it and what is the issue with omitting it?
@@boostav Usually used for thermal conductivity to thermal, thermal and electrical isolation, or vibration/shock effect reduction. As to why Lucid isn't...well, pouch cells don't? Can't really think of another reason. It is "atypical", but I can't be sure if its a good or bad "atypical".
Pack recycling (and repurposing in after market) needs to be reviewed as a criteria. The failure mode of a pack is that some number of cells will drift over the pack product lifecycle. These cells (out of many many cells) will either increase in internal resistance or not maintain a balanced charge relationship with their adjacent cells. Stated another way - eventually all cells will not act in exactly the same way with regard to charge/discharge. That said these are perfectly good cells for other applications - like home power storage which has a different charge/discharge profile. Imagine retiring your pack to your powerwall - good reuse. The other failure mode that needs consideration is thermal related degradation. The lesson learned on the Prius - the first mass market car that started the revolution - was that center cells which received less cool air tended to fail first. The lesson learned in both of this empirical data is that the granularity of the BMS and the cooling system are critical to battery life duration. Given the volume of this tech its plausible both these nits could be addressed. Especially if ALL manufacturers cooperate to create a non-proprietary solution for the common good.
Prius is a hybrid so no it didn't start this revolution. It also did not have liquid cooling which is the reason why you saw those failures. Being able to swap out modules is irrelevant as being able to swap one in that is in sync with the rest of the aged pack is a fool's errand. It is bound to fail again.
@@boostav I'd say the Prius deserves it's place in the EV revolution, yes it was a hybrid but it drove as an EV and that gave the mass-market a taste of what was on offer. The OP mentioned battery cooling, the Prius did have this, air cooled using a centrifugal fan. And his point on recycling battery modules is right, second-life use is possible with separate 48v modules, possible with BMW/Leaf/early Tesla batteries, but not with Tesla anymore.
@@boostav - Was not inferring swapping a failed pack back into a car - I was referring to alternative markets. Look up B2U storage solutions as mentioned on Matt Ferrell's channel
th-cam.com/video/gKSmIqGvZR4/w-d-xo.html
That said - there is a big business for repairing a failed pack. They pull the good modules out of a donor failed pack and replaced the bad modules in another failing pack. Its been very successful and lucrative for those doing it. This of course only applies to serviceable packs. There seems to be a move away from that with some newer designs that are not servicable but it was a very common thing to do. And why not? Let's be clear, a battery cell is just like any other battery cell. With proper handling at the cell level they are very low voltage and perfectly safe.
And as noted - the Prius, although hybrid, was the first electric (but not all electric) vehicle to capture mass market. It changed the perception about electric as people saw the incredible fuel economy and extended product life with most Priuses going over 300K miles before any major service. Arguably the GM EV1 was the grand daddy but of course it was not available (quite deliberately) in any volume as the documentary notes.
Your point about liquid vs air cooling does not appear empirically to have merit as the same "drift" phenomena has been seen on liquid cooled modules. Its just chemistry and probability. With thousands of cells per pack maintaining uniform charge/discharge characteristics over extended life is just not possible. Thus the 80:20% operational envelope technique and active cooling to reduce the stresses that would exacerbate the drift. Toyota, in the Prius, was the first company to do this and to their credit there are Prius packs, 20 years old, still on the road and performing beautifully.
Muy interesante.👍👍👍👍
Lucid must succeed.
Hopefully 🤞
👍👍
This compact architecture is downstream from their experience in providing battery packs for e-F1
Interesting comment on potting. I can see how the Air pack might not require it given the cells are fixed axially (by the busbar on one end and the cooling plate on the other). Essentially, Lucid's design strategy for cooling and linking the cells might have a side benefit of allowing them to omit potting. It definitely gives them a competitive advantage over other automakers who are still using cylindrical cells.
potting is usually a safety add not a thermal add.
@@BatterVswithAntonio Oh, I wasn't thinking about the thermals, though I have seen people state that thermals is also a reason for potting. However, my understanding is that potting is primarily used to prevent cell vibration and shock while also adding an insulating layer (that's the reason I'm using a form of "potting" for in the prismatic cell pack that I'm building, too).
If Lucid is also only using potting for vibration, shock, and electrical insulation, air gaps with strong axial attachments should serve the same purpose, which would allow them to omit the potting material altogether.
Imagine they'd make a version with 20 modules, where the two in the rear footwell can be slid to the left or the right to offer nicer comfort for one rear passenger. A lot to ask, but it would be nice to be dynamic rather than fixed, so the VIP passenger can decide where to sit.
Not going to happen, the dynamic bit.
Imagine IF Looocid motors, actually built a better car from First principle.
Batteries need not just power connections but liquid cooling. Having slidable modules would make that a lot trickier and you would eventually run into leakage problems since you'd have to use flexable hoses, and those will eventually age out.
@@wizzyno1566 I agree, good things are just not common in cars. It totally can be done though. If Lucid can given a super slippery sedan big cabin space AND a huge frunk and trunk, they COULD do this. But I'd rather them breaking the trend and just do a wagon version already. "But, manufacturing costs..." doesn't apply, wagon buyers have been paying extra since day one. With a smile. To the point that Volkswagen, Skoda and Volvo even discontinued sedans. The 18 module RWD wagon would sell like mad. Imagine the hauling capacity on that one. Would they even expand the frunk for RWD?
@@Cloxxkialmost anything CAN be done. But SHOULD it be done? No. COULD it be done in a cost effective way? No. Will the complexity cause more safety and reliability problems? Yes.
Its just a stupid idea.
And "but manufacturing costs" ALWAYS applies. Its just a question as to what extent. Or we'd all be driving bugattis.
Theyre already losing massive amounts on each car. They need to stop doing that before they start doing moronic pointless shit.
How much did the pack weigh. If they said, I missed it.
What sort of protection against puncture from below - does this battery pack have?
A: similar to the technology used by both the Death Star and Rebel Base Hoth in Star Wars, an ENERGY FIELD is projected just beneath the vehicle. "this Field is strong enough to DEFLECT any bombardment..."
Battery pack video and I was hoping to see a cell. I guess one cell was inside that zip lock bag.
Is this a bigger battery compared to Teslas?
standard 2170, nothing impressive
Much better video than the screaming old man.

I would have much rather seen the teardown from the get go, not after you have done it.

Looocid motors is FRAUDULENT.
@@markplott4820 i dont think so - the terribleness of everything is on display, finance wise.
They are very incompetent though.
Peter, is Kashoogi.
@@markplott4820 They've not broken promises to the levels of Tesla yet though, and they've been incorporated for quite a while. Seems a legit company to me, the engineering efforts for sure are, making every other brand just seem lazy engineers who don't care about user experience. Their software is the least refined, but that's a matter of time, good software has been achieved by others already at least. What Lucid does with packaging, was only accomplished by them. Mercedes and BMW are just utter buffoons in that respect. Much longer cars, same cabin space, less cargo space, no frunk at all. Lucid's is huge. Range better as well.
@@Cloxxki lol. They are failing, Tesla is succeeding. Broken promises don't matter. Results matter.
Are there contactors in the battery and where are they located?

The design is good for all performance meters, comprpmised for manufacturability though.
Also, their cars don't adequately protect from water ingress into the battery pack.
Not true - if you take the time to watch all the Lucid tech talks you will see that the battery modules have been designed for ease of manufacture.
Whatever you may think of Lucid, their engineering is impressive.
It’s easy to see how they’re losing $100,000 -$200,000 on every car sold.
Losing money is not good engineering
@@deepneasy I didn’t say it was good.
Lucid is following Tesla's play book - start out with an expensive vehicle and steadily come down to more affordable vehicles. The Lucid Air is currently their cheapest version stating at $87,400 and goes upward to the top of the range Sapphire at a start price of $249,000. Every EV startup will loose money when they first start manufacturing - even Tesla took years before coming profitable. Lucid has just raised another $3 billion to keep them going whilst they finish quadrupling the size of their current factory and also are building another factory in Saudi Arabia. Lucid is 60% owned by the Saudi PIF. Lucid will bring out their second vehicle, an SUV - project Gravity next year (it will be launched this year). Lucid's technology is used in Formula E racing.

Every part of vehicles sold to the public should be serviceable. It would be nice to see laws passed to make non-serviceable battery packs illegal. I don't know why the general public has gone along with thinking it's okay to buy vehicles built like this. Price wise it would be the equivalent of buying a gas vehicle that an owner cannot service the engine or transmission. Just run it until it dies. That's basically what we have here with current EVs. Disposable vehicles, sorry, more expensive disposable vehicles. If it was sealed and waterproof, I could maybe understand. But since they are all sealed for no reason, besides wanting to prevent someone from easily opening up and changing out a single cell that went bad I don't think anybody should be supporting manufactures that build like this on purpose.
Dude in Red needs his shirt in a larger size 😂
… for batteries with liquid electrolyte- do you think it’s possible to construct the batteries so that the liquid electrolyte could circulate in a coolant system, in order to kill two birds with one stone? Just curious..
Good work men ! Lucid must reduce cost and ramp production hopefully in a few years. Like to see them build a small truck !
You need to add a trigger warning to these videos, the Tesla fans are barely keeping it together here...
#LOSINGTHEIRSHIT
I was very glad to see the thermal isolation between cell rows and especially a pressure relief per module. This will greatly reduce the likelihood of a catastrophic 'thermal event.'
Yes, plate cooling the anode end has a shorter heat path than side cooling.
I was disappointed to learn that these packs are not serviceable. EV makers should make an effort to allow repairs to their packs. To my knowledge only Ford and GM are intentionally making cells or modules replicable today.
re: "I was disappointed to learn that these packs are not serviceable." well they're "serviceable" just at the factory, so not by "shadetrees" and "hacks" who might get their dumbasses electrocuted because they don't know proper safety procedures, and think playing with HIGH VOLTAGE is akin to playing with a "toy".
@@phillyphil1513 In the recent WSJ interview CEO Rawlinson stated that Lucid's battery modules were specifically designed to be usable for "second life" applications. Anyone who works with high voltage needs proper training and equipment, but there are many individuals and businesses equipped to handle HV batteries.
@@Miata822 re: "but there are many individuals and businesses equipped to handle HV batteries." well there are certainly many individuals/businesses who POSTURE themselves as being equipped to handle HV batteries. with the recent fire aboard the Fremantle off the Dutch Coast and the EQE garage fire in Florida in the news, unfortunately you will not be able to get me to forget that Gruber has subjected their nearby AZ residents to not 1, but 2 GINORMOUS HAZMAT FIRES while burning themselves out business and home. the first being in May of 2017 and the second being in October of 2021. i had already identified him as being a "Stockton Rush Type" before the real Stockton Rush. this does beg the question who's their Insurance provider...? anyway, i've now gotten a drive in both a Grand Touring and a Pure at my nearest Lucid Studio, one word BRILLIANT. 👌it's like a Taycan and an EQS had a baby.😎
I came upon a Lucid test drive car, endurance, in Venice Italy. Licensed in Germany… seems like they are just trying to put wear and tear on it…
And trying to promote interest.
Hi Sandy, what do you think is the difference between legacy auto manufacturers electric vehicles and Tesla electric vehicles? I will give you my opinion after I hear your answer.
Lucid is following tesla strategy (performance, then affordability), but 10 years too late... Hope they succeed though.
The engineering prowess in the Lucid battery pack is so evident compared to the Hummer's. Since cost per vehicle is difficult for Lucid right now, I wonder if the teardown has reflected the high cost at all. Could the adhesives and composites have difficulties around lead time or something vs steel/aluminum?
Much of Lucid's cost today is driven by outsourcing parts. As their factory expansion comes online later this year and early next, more and more processes will be moved in-house.
@@Miata822you don't know that and Lucid haven't said that.
What nice commercial voice Carl. I normally skip forward. Now I didn’t. 👍🏼

@@jockstrappery getting waxed you mean.
A little chilly in that area or?
I think Tesla has different chemistry for their 2170s going into the US performance model 3/y compared to US long range. The anode has 100% natural graphite and thinker electrodes. Uncertain about the cathode. So not only Lucid does this.
Tesla most certainly copied it.

Filling the void between the cells with a resin, silicon or foam. To reduce shock and extend the battery life.

Until they can build something with all this engineering in the 50k range and the 80k range, I don’t think the cars will be commercially viable.
"Billions and billions..."
The term UNIQUE is absolute. It means one and only one. Thus "most unique" or "very unique" are meaningless. Unique and unusual are not synonomous.
Peter, is uniquely suite to go to prison for FRAUD.
Pretty disappointed that this pack is not serviceable. Peter Rawlinson said that their pack was semi-structural because it offered more advantages than disadvantages compared to a fully structural pack like Tesla's 4680 pack. But if serviceability is not one of those key advantages, than what's the point? This pack must be significantly more costly to manufacture than Tesla's and is probably another big reason why their cars are so costly to make.
It's just the way for evs. Look at the teardown of the nio et7 pack for fun on here. Just as hard as the tesla 4680 pack. 😀
The modules are to hard to rebalance and keeping everything dry&re sealing it correctly in the field is an issue.
Just look at the clean rooms required to make the battery cells to begin with. 👍🏻
From the numbers I've seen, the first 4680 "structural" pack Tesla put into production, wasn't a lighter solution than the 2170 normal pack. Just when you bolt it off, you also get part of the interior to follow along out.
I think I'd rather have a NIO pack that can be robot swapped in 6 minutes, be it for swift travel or maintenance.
@@Cloxxkihaving thousands of swappable batteries in China might be OK , and a few places where Real estate is a premium- condos and Apartments but that ties up a lot of CAPITAL, and the batteries limit the models they can be used on, and the Swap stations will still need the HV and HiAmp Electric infras.
