#hyundai #ioniq5 #ev
I'm loving all of the Ioniq 5 content lately. It's very rare to see your current daily driver vehicle torn down and get some expert opinions on how it was made. So far everything I've seen gives me confidence that I made the right choice for my first EV.
I am secretly hoping that these EVs last longer than gas cars. Some Tesla M3s are hitting 300k miles. These are too new. My brother had a Rabbit GTI back in the day. The Ionic 5 reminds me of that, only much newer, and has all the stuff I love about EVs.
@@fjalicsthere are leafs that are well over 10 years, with just tires and windshield wipers replaced. Once this sinks in, EV adoption will skyrocket
The Ioniq 5 has very poor battery cooling/heating. The difference between the lowest and highest temperature can be 10° C, which means that the car often rapid- and coldgates, sometimes in the same charging session.
@@fjalics TM3 made after 2019 should last 750k miles.
@@davidbeppler3032 I got mine Nov 2018. Only got 60k on her. Dual motor too. I had a Prius before that. Off the line is quick. 🙃
When they flipped it, I didn't realize the cells were removed. I was like, GREAT SCOTT, they are going to flip it manually with only two people? Phew
💪
When you hear the bells ringing, it is (usually) time for the unique Munro spinach break, mandatory for each employee. Sandy decided, that this saves costs vs. using a crane or a six million dollar man or a bionic woman. 😉
@@Stefan_Dahn 😜😜😜
@@Stefan_Dahn😂😂😂😂😂😂😂😂😅
Edge cooling pouch cells was cutting edge in 2015, glad to see it finally made it to production. You get the most efficient heat transfer by going in plane to the electrodes vs. through the stack to another fin and down to the cold plate.
Bjørn Nyland discovered highest delta temperatures between min and max temp. in the pack. Over 10°C (a.k.a. Kelvin). That is very bad.
So many amazing engineers in these comments. Thank you
You should email your comment to Hyundai, im sure they will give you a job right away!!
@@Stefan_Dahn That does seem a significant variation. What are other battery designs getting? This battery does charge very fast so one would expect a correspondingly higher cooling load and thus a higher temp differential for a given cooling capability. A higher differential is not necessarily bad so log as all cells are kept within reasonable wear levels. The devil is in the details here. perfectly consistent temps would be nice but you never get that in real-world cooling systems, so the question is 'is it good _enough_?'. Where I guess 'good enough' means >80% capacity after a decade. The car comes with an 8-year 100,000 mile battery warranty, so they are expecting at least 500 charges to produce less than 30% degredation.
@@Stefan_Dahn Dude Celsius isn't Kelvin LOL
I love these presentations as the focus on a brief overview requires a clear understanding of the totality of the related technology. Seeing how I understand what I am being told, this truly leads me to realize how well Munro Live folks are subject matter experts. Well done.
Finally, more detail on the Ioniq teardown. Great analysis. Can't wait for more videos!
Amen.... Finally coverage of the battery removal process. Well done Munro Live!
I was just linked to this video. Wow, you guys know your stuff. My brain is throbbing from all of the info. Keep it up!
More to come!
As an EV6 owner(Love the car), I've been waiting to see my battery pack internals. Appreciate the walk-thru!
Great video with easy to understand descriptions, without tons of acronyms to decode. Thank you gentlemen!
Glad you enjoyed it!
🙋♂️THANKS ,JULIAN,ANTONIO AND THE MUNRO TEAM 🤗😎💚💚💚
Wow, more than I ever wanted to know. Julian & Antonio are very knowledgeable.
Great getting to see a pack breakdown. I’m definitely going to be consuming more content like this. Thanks for sharing
Two separate instances of battery pack impact damage and insurance companies scrapping the vehicles after learning replacement cost is 60k Canadian. Neither vehicle had any warning lights or indication of faults in the computers. Not acceptable.
What's unacceptable about getting a new EV? If an insurance company stupid enough to pay for it. When did scrap yards go out of business? There's always a lower cost alternative. Hyundai deals with realistic problems Instead of blaming others such as calling it driver error. Thanks for the BS scaremongering FUD. FWIW Rusting Cybertrucks. Is truly Unacceptable...
Great explained battery pack really appreciate your helpful information. I am also working in battery technology last couple of year and had 15 years in power train casting design for product cost and performance enhance. Munro is doing really wonderful job.
Thanks to both! 👏👏
Thanks for watching!
Interesting to see the integrated fuses for the cell voltage measurements on each of the module interface pcbs! Very nice (if somewhat costly) addition to avoid shorts in the BMS wiring leading to a serious thermal event
TIM can provide the stability at vibrational stability with modular design feature. The battery cell temperature shows the lowest level because the cell resistance is very low compared with others. Integrates cooling improves the pack assembly and disassembly which is good for productivity and recycle.
That internal welding looks to me to be more likely spoolgun rather than tig. Though I've done lots of welding, I'm by no means an industrial expert (I know only what I know and not far out of my experience). I'd be interested in what you think.
Great info to see. Would love to see a teardown next of the ICCU especially with the NHTSA investigation and recent software inspection they just released.
The fact that a software fix came out makes me think this was a software problem to start. Old school firmware guys are pretty notorious for being ridiculously slow and lazy to do anything, and a 6-12 month release cycle to fix ridiculously bad errors is par for the course.

static.nhtsa gov/odi/inv/2023/INOA-PE23011-2700.PDF
@@FuncleChuck My (vague) understanding is that the software fix is to prevent too much flow thru the ICCU under some circumstance(s) causing the fuse to blow. Once it blows the unit needs to be replaced, but the software lowers the max power (?) that will be sent under that condition and keeps it from bricking.
@@ritchie70and prevents the car to charge (AC as DC is unaffected with this) at rates it was marketed to do which sucks.
I feel like the benefit of an easier to disassemble pack is recycling. I know you can shred the whole thing, but I think it would be more environmentally friendly to separate as many of the big components first as possible. Yeah it's a one time scenario, but it's also a major event. Maybe if you can get the design so lean as to not matter as much. The 4680 pack feels like it's getting there. I'm not as concerned about pack repair as I once was, I think battery chemistry and design will get to a point where failure will be so low as to not matter. Failure rates are already pretty low with current tech. Seems like most repairs were on older vehicles with suboptimal thermal management.
Battery pack price will continue to decrease as well. But until it goes down to sub $5k per pack, there will be a lot of ppl that will hold off on buying an EV. I plan on trading my MY after the warranty expires. I think we are still 8-10 years away from cheap battery pack replacement.
@@Teddy_M85 Yeah, also a reason I'm less concerned with pack repair. Not only do you have to gimp the new cells to match existing degradation, it's generally not an easy process. And yes pack prices will come down with scale. ~10y is probably a good estimate. I will continue to monitor my M3 pack health. As long as it shows no sign of accelerated degradation, I plan to keep it for at least a few years after the warranty. 10 years at least unless something really revolutionary comes out. Already owned it for 2.5 years with maybe 3-4% degradation. That 9/10 year mark is where I break even with gas savings vs. extra vehicle cost of what I had.
When the pack is worn to the point that it will be recycled, you are probably recycling the entire vehicle anyway.
@@Zeesneakyninja What about single cell failures?
Can you point to me where this mystical "Shredder" is? Or did you hear this from Munro?
To me it seems the bossed areas below the modules essentially turn the coolant flow of each module parallel to each other, instead of being in series. That's really smart. They controllably "short circuit" the main coolant channels, some for each module.
Such a great car! Great engineering!
There has been a few stories in Canada about the cost of replacement battery packs after running over road junk. In the three cases that were mentioned on the KZhead channel MotorMouth, just the skid plate received some scratches from the damage, but it resulted in the Ioniq5 being written off because the replacement battery cost was $56000 CAD, add to that shop fees, labour for the battery change out, and taxes beings the final cost to slightly less than $65k CAD. Are these battery packs just as expensive in the USA, and are they as easily written off when the shielding has been damaged, or is Canada a special deal? To me, I will never buy a EV where the replacement battery cost is more than the the cost of the vehicle.
OMG I really really don't care if you buy an ev or not.
Accurate comment. I'm also tracking that case in Canada. At first sight, the replacement cost makes no sense.
Two Bit da Vinci mentioned it to Sandy recently in a interview. Sandy was blown away at the cost. Would love for him to follow up about why he things Hyundai's price is so high.
I am soooo glad I got the extended warranty bumper to bumper on my ioniq 5. Can't imagine myself working on anything in here.
We had a car that was written off (totalled) due to a small scrape to the cooling plate, causing the coolant to escape. Repaired it with JB Weld and retitled it.
outstanding !
Nicely done 👏
Thanks 😁
"getting a single module out, usually is not a super simple task" and goes on to question the need for a practical and easy to remove and reapply rubber seal, just for the technician to say this pack is one of the easiest to disassemble! 😂 Dude was driving his point for a whole minute and the tech guy flipped the conclusion 180° 😂
Is this the battery pack that costs 60K from the dealer to replace that's been in the news from 2 different customers/stories lately?
The Ionic battery pack is $60k from Hyundai. The brand new car is only $50k.
Also the brand new car depreciates something like 68% in one year. You can buy a used 2023 for $23k right now.
To be exact, it is like $56,600 Canadian dollars quoted in Canada
@@dmitripogosian5084 $1,500 Labor. Would be $43k US dollars. Once they are driven off the lot the entire car isn't worth $43K.
@@real100talk5 Holy cow, that's terrible... Or great depending if you are buying new or buying used! I think I'll pass.
FYI the post shows how easily repairable it is.... Google what a scrap yard is.... Plus the need for a brand new battery pack is infinitesimal..
You probably know by now you dissected a $56649.98 battery pack, nice
That's in Canadian dollars, so they do not care :)
GOOD JOB!
Great video, I wonder if the thick layer of Thermal silicone also helps with shock absorption? to the battery cells, and or to help with expansion when the cells get hot?
Good video, thanks guys!
You bet!
21:42 Julian’s Shinola watch is based in Detroit, just like Munro and Associates. Class! 😉
Molded composite battery chassis would be the way to go that slides into place and locks in with quick release,& power plug, cooling lines.. .
Great review old mate. I’m new to your vids but I would very much like to see a strip down. I understand this is recorded live though. Cheers
since i work on maintenance of hyundai EV's this is nice analysis of what may i expect in the future to work on.
The future is now!
Those circuit boards in the modules are simple breakout boards and the components on them are fuses (it's even labeled on the board). All the things lucid had on the module circuit board are external to this module.
great video very informative
Glad it was helpful!
Would the thermal interface material have an added benefit of reducing shock by providing some cushioning the the battery packs? As well as reducing noise.
Careful the battery is worth more than the car
Great informative video, thanks. That SMC (unsaturated polyester) bottom "shield" for the high voltage battery pack sure looks vulnerable to impact damage from debris on the road. Shouldn't Hyundai/Kia/Genesis use more substantial material for the shield to help prevent impact damage to the battery pack assembly including the battery cooling system (i.e. cold plate)?
There's two recent cases in Canada where (what appears to be) minor damage to the shield voided the battery warranty. The cars needed a $50k replacement battery!
Thank you for the video 😊 Will you cut the battery case to show the cross section?😊
the launch models of the I5 had a solar roof for charging - would be interested to see how this was implemented without having to close the contactors - I'd imagine a seperate low-current feed into the pack with diodes for isolation - did you see any signs of this ? Would also be interested to see details of how they do 400V charging, and what power they can do this - ISTR reading they use the motor as part of the converter, like the Renault Zoe did for high power AC charging. Also the AC inverter for V2x - is this part of the onboard charger ? Hopefully you'll be diving into these boxes soon...!
I'm sure any external power was routed through the OBC or inverter just to prevent over-charge. I'll make sure to bring this up in the discussions to make sure its addressed in the videos. Thanks for the input Mike.
@@BatterVswithAntonio But if solar was routed through the OBC or inverter, it would have to close the pack contactor, and the contactor coil current to do that would eat into any gain from the solar panels. As solar would be pretty low power, and nowhere near the 800V pack voltage, I'd think the best way to do it would be to feed it into the pack housing, where a boost circuit would convert it up to 800v, protected from overcharge by a simple overvoltage cutout and diodes to prevent backfeeding.
Probably just charges 12v batt. To run stereo, HVAC fan maybe. Things like that.
Good question.
@@coreyverisario6570 re: "Probably just charges 12v batt. To run stereo, HVAC fan maybe. Things like that." yeah, it was just a fancy maintainer (ref: Battery Tender) for the 12V, which indeed benefits the HV battery albeit indirectly by way of the DC to DC converter not having to turn on. people still don't seem to process how there's just not enough surface area and not enough output to bother with the complexity of integrating it to the HV system to begin with, and even then the output that it DOES produce is dependent on weather, time of day, etc. yeah, all the same variables that impact Renewables on a large scale also impact small scale Renewables placed on the tiny roof of a vehicle. this reality combined with the COST (God forbid we forget about that) is why the Solar Roof was only offered on the limited run Launch edition, very similar to the other Hyundai products that got Solar Roofs. it's purely a "sales gimmick" and not meant to be anything more, and that's fine as all the Manufactures offer a "gimmick" in one form or another to make a "green statement" and entice consumers to buy their vehicles over the competition, naturally some features are more "gimmicky" than others.
They rock!
So that's the infamous $60,000 battery huh?
🇦🇺 Would like to see an animated exploded view of the battery pack. This video seems to already have the components disassembled.
This is very great content and very through engineering review. I own an Ioniq 5 and myself am also a battery module designer (pouch cell). I can see that the thermal management design between module and pack can improve for sure. 3mm of TIM is asking for weight/thermal resistance trouble. Are there vent ports in the pack? Thermal propagation is becoming a heated topic in the industry and love to see how pack design will transition to eliminate TP.
A good thermal management is crucial for longevity, I have a little bit my doubts about this design.
They went over it, there are no valves just that gasket designed to release pressure in the event of overpressure.
TeslaBjorn's drives in this car while using Car Scanner showed a huge difference between the highest and lowest temperatures in the pack (I think it was 8 or 10 °C), so yeah, this cooling plate with that much TIM is non-optimal and results in charge speed throttling on long high speed road trips. I appreciate how much more serviceable, and probably recyclable, this pack is compared to some of the others though.
re: "Thermal propagation is becoming a heated topic in the industry..."
@@phillyphil1513It was a very heated exchange
We have a Prius V and are very happy with it . We have been looking at the Electrified G80 to replace our other ice car, after seeing the stories about MINOR pan damage totaling the car...NO WAY, NO HOW!!! The newest Prius is looking better every day. I was looking for a bit more room and comfort, but I can do without the super-premium insurance costs.
Clearly these packs need a better SKID plate! Recent insurance claims demonstrate this.👍👍
As ever this was great, but I'd have liked a little more time on the module construction. I didn't fully understand what was meant by the Z-fold and pancake construction flavours, nor how the tabs are connected to the end pieces. I like this design though - it seems quite space and weight efficient, yet still fettlable. And keeping the coolant separate seems very neat. Maybe they can iterate down to 1-2mm of goop over time and some some weight and money.
How many amps was each cell? What was the total capacity of the pack in kWh?
is there some kind of membrane pressure and humidity relief ? i know that most car do have them. thanks.
21:30. These fusable link I guess are to protect LV modules short circuit, however these are in serie anyway so all the HV could come across these fuse somehow. So why these are not glass or sand or ceramic surrounded to not have a plasma event? Normally fusable link are on each cells in parallel so this protect for 3.7V maximum, however these big fusable link are at the HV level !
For battery heating, does it use the heat pump?
I really appreciate you guys for making these videos showing us how our cars are made. What's your opinion on these types of cells. To me they look like the Lipo batteries used on RC drones. Can we expect these batteries to last for 200,000+ miles? Assuming they are properly taken care of?
Very valuable insights. Thanks for that. @24:53 Do we know whats the cell chemistry ? Whats percentage split of NMC ?
The cooling pack looks very neat.
Would you say it looks... cool? 🤣
@@MunroLive it's certainly a design that flows fluid fluently. 😀
Is the coolingplate protection-cover also an isolation piece it doesn't seem so. That would improve the cooling/heating effective and Effeciency
Yes, this seems like an omission. Just 10mm of foam in there would make battery warming dramatially more efficient. maybe there is enough self-heating in use for it not to really matter? But for things like camping mode overnight we'd really appreciate some insulation.
What is a 'thermal flow screw'? I suppose I should go back and find the ID4 battery pack teardown to find out. I'm guessing some kind of drill-cum-screw that you put in and it spreads the ali whilst cutting a thread? Maybe you [put it into hot ali so it's more malleable?
I like serviceability of this module. I know your primary focus is on reducing assembly costs, but at some point things break and have to be repaired. If you watched some things that have to be preformed in order to do repairs some focus might be given to this area. In a way the process of focusing on cost only is the same as bean counters being in charge of production changes. A better strategy would be to consider both issues when possible. If you don't believe me ask people that have to preform repairs on ICE and Electric vehicles., which increases cost of vehicle ownership . Really like your channel and have been watching for a long time.
I would hope the smc? cover would be a little bit harder. Over here if there are any dents in the battery back if will fail yearly inspection and the battery back must be replaced. I just wish the battery packs would be better protected from outside forces.
it have the cooling plate then the thermal paste THEN is the actual battery cells. But yeah if you decide to off-road/skid off on some large rocks. You will need some battery work. And looking how it is assembled you will need a whole new battery. Once the cooling plate is damaged no one will be reapplying the cooling paste just to save you a few thousand bucks when they can overcharge you for everything :D
@@qa1e2r4 There is a post in these comments about someone getting a new paste+cooling panel+cover fitted (due to damage to the bottom of the pack). So it is happening.
Given the separation of the packs and the coolant, what are your thoughts on the reasoning behind the expensive battery coolant they use and the maintenance on said coolant.
is the coolant for ioniq5 also expensive? I just remember expensive coolant for Kona
Thanks for the great view! I like the liquid seperation from the pack, but it would seem the cooling/heating would be very uneven between the module nearest the inlet and the module at the outlet. It also seems like a lot of heat/cooling would be lost from the bottom to the outside as that thin plastic sheet doesn't seem like much insulation. Perhaps it is made up with a beefier coolant/heat system, but that adds cost and reduces efficiency.
With the exception of extreme cold weather environments, mostly you *want* heat to dissapate from the pack. If anything this probably helps reduce the demands on their cooling system.
Actually the design of that serpentine pattern has the hot side run parallel to the cool side which results in a pretty even temperature throughout the pack. Certain arctic birds have a circulatory system that works a lot like this to prevent them from suffering shock from ice cold blood reaching the heart...
@@ApparitionElectronic Makes sense. Thanks!
We have another exceptional engineer in the comments. Thank you
Thought the same, it will be very interesting to see winter performance of the Ioniq 5. If you try to warm up the battery from underneath, nearly half of the heat will dissipate to the outside.
nice,, wonder why they didnt put the cooling on the top ?
Are the 800v packs split into 2x 400v pack with a solenoid contactor ?
At least it's possible to replace a bad module. Unlike other manufacturers filling every void with epoxy.
Thank You for All that you are doing for our Planet Earth.... Peace.. Shalom.. Salam.. Namaste 🙏🏻 😊 🌈 ✌ ☮ ❤
How big are the modules? Could you show us the measures of each module?
There’s videos on owners reportedly charge $60k + to replace the battery.
Replacing the hv battery on the ioniq5 cost around $ 40k usd. It doesn't take much to damage the skid plate, any damage to the skid plate will hit the battery causing a small dent,. hyundai dealership are private owners and will quote you all kind of prices but all of them will quote you the same price for the part number. And the part number will be around 40k usd. In other words, do not hit anything on the road with the ioniq5, because damage done to the hv battery will not be covered by the warranty. Just like windshield, or tires.
Why don't any of the OEMs use single--phase immersion cooling to simplify the thermal circuits?
Great video. I may have misaed these. Will the fusible links create additional failure/service points? Does a link failure incapacitate the vehicle?
Looks like it’d only affect part of the pack. Maybe 1/8th?
Certainly, but if a link fuses you may bigger problems to worry about.
Question - why not install pressure relief valves on two diagonally opposite ends and have air channels across all modules so pressure in the entire battery pack is same. Or in case of extreme thermal runaway, there can also be rupture discs?
Because it would (probably) cost more than using the expanding seal they've used (which obviates the need for such vents?)
The CEO Cory returned the car dirty - and second reviewing team points out at the dirt he didn't bother to clean. Well done, guys!
Does the design explain the fast charging capability?
Hi what is the max. discharge rate of these cells? Thanks
Are the dealers allowed to replace individual cell modules?
10:07 LOL why y'all got one of those hospital sliding table things? 😂
Perfect for the 500Kg patient!
Good standing desk!
Tens of thousands of those are sitting in medical scrap facilities waiting to be broken down for scrap metal and the landfill. They probably rescued some of them and gave them a second life.
Two in Canada now got written off by insurance. Because of the cooling bottom. So not service able.
Love these videos but would have liked to see them build out a section or two to see how all the parts assemble. Also it’s a shame that even though the pack is meant to be serviced you can’t apparently do anything in the event of damage but replace it all. Doesn’t make the effort of modular design worthwhile.
I've seen the batteries are super expensive, replacement Ioniq5 batteries from Hyundai cost around $60,000 just for the pack, not including labor. One guy he paid $55,000 for the car and hit something on the highway that damaged the safety cover and Hyundai wanted $61,000 to replace the battery pack, his insurance company totalled the car even though the body was untouched by the item he ran over.
This guy is all CAP. It’s $30,000 USD. I looked it up. It was not Hyundai corporate that charged $60,000 CAD. It was the greedy Hyundai dealer and incompetent insurance adjuster.
Also the damage was caused by the driver so the battery was not covered by warranty. It wasn’t only the battery cover that was damaged but also the battery cooling system, so it couldn’t be repaired by the dealer.
@@JohnLee-db9zt - According to the report he hit something at night in the dark laying in the road that probably fell from another vehicle.. NOT his fault.
The rivnuts would mitigate a galvanic corrosion issue that might exist with threading steel bolts directly into an aluminum extrusion.
When you hear the the bells ringing, it is (usually) time for the unique Munro spinach break, mandatory for each employee. This saves costs vs. using a crane or a six million dollar man or a bionic woman. 😉
The bedside hospital room table is super random. If I remember correctly there is a mirror that pops up if you slide out the tray. :P
Yes, the mirrors are still there
1:55. That’s a long path. Won’t there be a huge coolant temperature delta between the cells nearby the inlet vs the outlet?
Apparently these packs can have a delta up to 10C, so yes this may be an issue. Do other packs have parallel, rather than serial cooling paths? There could still be differential cooling in that case due to 'shortest path' issues.
When they went to pick up and flip over the battery pack shell, I thought the batteries were still in there for a split second. lol.
I'm not the expert, but arent most of those aluminum welds MIG, not TIG? They look like MIG welds to me on the pack assembly? Can you point out where they were doing manual TIG welding?
Most are friction stir or MIG, the round bits were manual.
I'm not an expert either, but I'm quite certain most, if not all, the welding in that extruded aluminum structure is robotic MIG welding. The start locations for similar weldments are very consistent, and in places they wouldn't typically be. Starting off the joint ensuring arc is properly established perhaps. This can be seen along the length of the structure around each of the perimeter tubes, internally where part of the weld bead creeps up the "rib" extrusions on either side, and at the box tubes at the coolant inlet side. But like all processes, there are sure to be QA verifications and manual touch-up of areas that need it. So not every weld may look, or be applied, the same.
@@peeweedan9 The welds except the friction welds look horrible, my guess is that they are manual welds. one weld even does not connect the parts properly over half of its length. No idea who let that casing pass quality control.
Is there a way you folks can find or retrieve the Ioniq 5 vehicle that Hyundai quoted $60 grand in BC and redo the batteries yourself and show how much cheaper it is to service or repair?
Nice

@@MunroLive OK wow. I noticed the improvement immediately over old footage in any case
Thank you!
You're welcome!
Glad i bought a Mazda CX 5.
The most important issue of all in EV is the safety of passengers from Thermal runaway. I believe that these battery packs should have a pressure relief valves piped in and incorporated to the chassis of the vehicle protected by thermal resistantant materials and vented upwards in case of a runaway.
Why do you want them vented upwards (into the car?) What's wrong the sideways venting through the seal this pack uses? Or indeed venting downward away from the car?
@@xxwookey not into the car. if they could design a safety valve incorporated into the chassis vertical structure of the car that would guide the violent burnoff to the roof area like the rear C- pillars. If you watch videos of a thermal runaway of battery packs under the car would think to step out safely when those things ignite. The amount of heat and energy those things make is like a solid fuel rocket burning off.
Is there anything known about how many Charging cycles such a LiPo Based Pack can have? For LFP it is 3000+ cycles, for NMC it ist 1600-2000+ cycles, for LIPO batteries I have 500 in mind but that would mean, from my calculating perspective, that those battery packs are a bit short lived in comparison.
Interested to know - does the EV6 has the same construction?
Yes EV6 has same construction. Ioniq5 and EV6 can even interchange battery packs
any thoughts on the $~500 “low conductivity” coolant that apparently only lasts a few years?
Standard coolant has corrosion inhibitors to extend the life of the radiator system, the issue is when you get into very large surface area brazings, you use a lot more high fluoride flux (vs cooling channels for example) to prevent oxidation during brazing and that flux reacts with the silicate based corrosion inhibitors and forms a gel byproduct that will clog the system and cause over pressure leaks. A few flush cycles should get out the residual flux, but at this point, no one knows how many cycles are needed to reduce levels to the point where there is no further gelling. So, yes, absolutely. Replace it after a while. Coolant companies have a few products out that are specifically formulated for EV applications.
The blue coolant is not used on the new Niro which also has an external cold sheet. It's not clear to me if Munro's Ioniq 5 has blue or pink coolant but I was under the impression that the expensive blue stuff is being phased out.
EV6 uses only standard pink coolant for battery and electronics.
Is that Lithium Polymer battery?
Will the Ioniq 5 N have a different pack design?
They said it's totally different include cooling system.
