As someone who has worked on cars for nearly 20 years, many of them older, I appreciate that Hyundai has not gone the Tesla route of integrating several components into one box. Serviceability is a significant factor that seems to be increasingly getting ignored, but it is critical for keeping cars on the road as they get older. The more components that you integrate into one service part, the more expensive that part gets. People may be willing to spend $2000 on a box in order to keep their 3 or 4 year old car on the road, but they probably are not going to be willing to when that car is 8-10+ years old. Those cars end up in junk yards. Being able to service components affordably is super important. I would much rather have a more serviceable vehicle and sacrifice some of the grossly over-rated frunk space.
I'd that "one service Mary" is made in huge numbers, making it cheap, is interchangeable between models, and easy to remove due to lack of plumbing, I'd say it would save money when it comes to keeping cars "on the road". Not to mention, no guesswork faultfinding, fitting the wrong part and having to find another component.
what about the argument of, less parts -> less chance of something breaking down -> lower chance of needing service in the first place (therefore, last longer too)?
(I own both a tesla and an one of these, I appreciate my window regulators working, having a volume knob, working wipers and defroster I can find WAY more than having a “frunk or an octo-valve” not even to mention the superior, Hyundai service, and range.
Explaining the evolution of design changes over the years is BRILLIANT! If you could use old footage or part comparisons like you have done with the Tesla Plaid, then your videos have a higher value to us viewers. Speed of innovation is now part of buying experience...
I think the Hyundai is a press loaner so they don't have permission to take the guts apart. On the other hand, VW and Ford *wanted* Munro to take their vehicles apart to give there honest thoughts.
Please let Jordan off the hook and give him an episode of his own. I think he is a natural and could easily fill an entire Video with his knowledge, and to me at least it seems that he is somewhat being held back by Kory & Sandy. But as usual it was a great and interesting Video, Thanks for sharing your insight with us!
Each one of the crew has so much to offer in background and knowledge that they are always sharing a limited time with every subject but I think your point is valid. Cory is such a wealth of technical understanding and has such a digestible way of explaining what he’s seeing that I always come away with more insight into what I’ve just watched, and always a little dazzled by his knowledge. I would like to see Jordan do one of his own and just dive in headfirst. It’s obvious he has a great deal to offer. This is a fantastic channel and such a great learning platform.
Getting better and better. Cory relaxed. Jordan is so clear and concise it's amazing. No wasted "ums' and "ahs". He totally understands the engineering and is comfortable in his skin. I love Sandy, but sometimes I just want simple clear explanations without all the other stuff.
Yes. Toyota and Honda make their cabin air filters easy to replace, but you have to realize that the Model 3 has 2 of them just like Mercedes and they put the filters wherever they can. Not saying Teslas couldn’t do it but also because they probably don’t want you to messing around with the car to do it yourself if you’re not mechanically inclined.
@@princesses2909 Tesla does give you detailed instructions how to do it yourself, it's just a bit annoying to do. Doing that every 2 years... I suppose I can live with that.
Looks like the Koreans understand the advantage of serviceability more than these guys. Intergration just makes replacing faulty components so much more expensive....and profitable for the manufacturers. The trouble with Munro they can't see the forest for the trees.
@@bitsorbytes You don't have to remove the frunk to change to the filter though ;) there's an opening inside the frunk. Hyundai is known for serviceability.
@@bitsorbytes Not only is there a pop-out panel in the frunk to make it easy and tool-less, but what's more: the frunk is SO easy to remove! This blew me away: there's a light in the center-front to show you what's in there while you rummage. It would have been pretty easy to unplug by just pulling out the bolts, lifting the front a bit, and feeling around. But they were so thoughtful they added a whole extra connector on the far-right, so you can unplug the connector visually before you even undo the bolts. JUST to avoid someone not noticing the light and ripping off the harness.
@@bitsorbytes they say once every year or 15k miles. For how easy and cheap it is, I’ll probably go with something like half that. Maybe once during fire season too.
One of the best channels on RU-vid for technical analysis, and detailed breakdowns of current technology. This old gear head appreciates the deep dives, and being an EE, the EVs are very interesting.
Hyundai and Kia have a lot of potential to reduce the numbers of hoses and their lengths. This reminded me of the Mach-E thermal management hosing madness... It seems like there's potential opportunity to make some changes for the components along with their wiring and hoses to be moved around and/or combined. Once they deal with those wiring and hoses, hopefully they'll come out with a nicely polished front trunk cargo space and possibly some weight reduction. Small things can turn into a big deal when everything adds up.
Sure, but what if it is cheaper to produce it this way than a Tesla? Should they go more complex with something like an octivalve system, just to be like Tesla?
@@AudiTTQuattro2003 - Tesla is way cheaper to produce, and savings in materials cost, weight Penalty, and efficiency Loss. no one on EARTH can Engineer like Tesla can , the model 3/Y were design by SpaceX. the Octovalve & Super Manifold was SpaceX.
Go back and watch that Mach E video. I think you might find that this is a MUCH more compact assembly despite also being two coolant runs. The Mach E was also using loads of generic hoses and connectors which limits how tight of a bend they can go through which negatively impacts the orientation, parts lengths, and manufacturing assembly. These vehicle-specific hoses may be slightly more expensive up-front cost but should be faster to assemble and allow for better packaging.
I agree with others that it looked better than Ford but not up to Tesla. The great thing to know is this vehicle already has great range, so relatively simple packaging improvements should improve efficiency even more. I think Hyundai/Kia will be a real force in the future of EVs. Their purchase of Boston Dynamics was no coincidence either. They are shooting for autonomy asap.
Thank you Cory and Jordan. I have a Hyundai with the cabin filter under the dashboard. It is a diabolically hard thing to access. Moving that to the location in this car is a *really* positive step. As ICE cars tend to have some part of the engine in that location, such a simple move is usually impossible. Moving that item to this new location is a real world benefit that should not be undervalued.
Many cars have it in the glovebox which is not as convenient but completely fine to service. Although i really like to see EVs using larger, more capable filters due to having more space available.
@@drkastenbrot I have to remove the entire glovebox to access mine. It is still decidedly hard to access the unit the filter is in. There is a leaf causing a buzz in it now, and I am loath to go through the torture to clean it out. 😞
@@dogbreath6974 usually more often than owners can be bothered with when they're hidden away like many are... I must admit that I didn't change the cabin air filter many times on my last ICE car (2009 Ford Mondeo), mostly due to it being so hard to access. I've changed the filter more times during the three years I've had the Tesla Model S (old, small filter - the newer ones may be a bit more fiddly) than I did during nine years owning the Mondeo (ok, so the first few years I let the local dealer do it during yearly service...)
Very nice breakdown. I do find myself disagreeing about the serviceable fuses. Fuses goes from time to time. Long term, the owner wants to be able to replace those fuses and even the 12v battery. Not everyone wants go to the dealer which can be expensive.
Yup, I honestly don't like Tesla's model where they try to detect overloads in software and expose the (very expensive) front control board to potential over-currents. This chap has a very good video on the Tesla low-voltage circuitry, but as a designer, I cringe a bit at the assumptions they make... See: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fUCgLCbX_18.html
The Ioniq 5 has two different coolants. They have a Low Conductivity fluid which I think is used for the HV battery and a Standard for all other systems. I would like more technical info on this. I don’t think any other EV has this difference. The Low Conductivity is to be changed every 40,000 miles or 36 months, and I understand it is very expensive.
@@mike6669-d2j Well, Tesla also doesn't have an 800V system and could have calculated the risks differently. If it's also expensive and has to be changed regularly, it does make sense to have a limited amount of it, i.e. a separate system. I don't know what the rate of leaking coolant into batteries is in these types of systems, but for every million vehicles, you probably end up with some leaky ones, at least in accidents.
I actually do not dislike the packaging under the hood except for the atrocious 12V battery. Cars and their parts still break down I love how accessible they are in this car rather than have them hyper packaged like in a Tesla making serviceability much more complex and thus expensive. In fact there is no study showing that one is more reliable than the other, especially in Tesla's model S case some parts are notoriously more prone to failure. Would be nice if Munro also addresses this and see what changed to improve this.
Cory sounds more and more confident hosting videos. I think taking the Plaid to the track helped him shaking off those nerves. I like his methodical style but sometimes I miss Sandy's raw coughing, and unpolished cowboy when speaking the truth. These videos might be extremely valuable for any potential buyer of an EV.
So a car designed for mass deployment, ease of access and repairability. It also doesn't look like an amorphous blob. Electric cars are now grand. The good ones are all fine. So it comes down to smaller things like being a fresh design update, or what suits you or can it be easily serviced with a loaner available.
Wonderful topic coverage, Would love for an on-screen graphic or two defining acronyms and/or initials used in the voice track. Thank you for your work to make adaptable/leaner designs and products.
Wow! Great report! Tesla seems to be far ahead in engineering, etc. This is much better than standard yt reviews and replays of automaker's slick advertising.
I wouldn't say far ahead in engineering, just a different purpose of direction. Tesla's charging tech is already less advanced. I don't mind not having a frunk if I can access stuff for maintenance much easier. The cabin filters on my Model 3 are a pain to access. This seems way easier. I would also imagine cleaning out the A/C coils would be easier on the Hyundai. The moldy smell from the Model 3 could be a design flaw too.
@@SiuLeung They are far ahead though... It's plain to see. And saying the charging tech "already" less advanced seems to imply everyone will catch up in other aspects real soon, as if their charging tech is less advanced. What exactly are you pointing to here? Tesla hater detected?
@@SiuLeung The only thing is that electric cars don't really need a lot of maintenance. In this car maybe since they added a plethora of hoses which could conceptually leak and might need addressing. But that brings us to the point why'd they take this design approach anyway? The car does not look like it was built as an electric vehicle but a general purpose car where they just pulled out the motor/trans and retrofitted an electric motor and supporting components.
I totally agree and I didn't have to yell at the screen as much. Only when Cory mentioned a valid reason for the two coolant loops but didn't think to question why they were different colours.
Now that they’ve got much space in the absence of engine they’ve neatly put everything on sight and easily accessible. Korean and Japanese don’t really care about frunk as much as the easily accessible technical parts fact!
Removing the frunk on a Tesla is fairly simple. I’d rather have a nice frunk, even if I need to spend an extra ten minutes removing it in the unlikely event that I might need to get to those components.
@@lemongavine My point was not the frunk, this one has it although very shallow but the engineering behind those part’s positioning is evident, an engineer can understand what i’m saying! they’ve modeled everything for wrenching and changing if it’s necessary it’s a Japanese/Korean philosophy! Germans don’t do that because of the pride that they have in their products! I guess Tesla is closer the European philosophy.
I appreciate an underbonnet area that isn't crammed with kit so you can't get a credit card between components. I'm happy to lose a small front trunk if the car is much easier to service, particularly it that's pretty much all the servicing it will need.
...yeah, the nerve. Who would want to be able to replace a battery anywhere in the country, when you can depend on Tesla service to schedule you an appointment in three or four weeks.
All EV's use them because of legacy 12-volt electronic systems in all autos. Even Teslas still use a lead-acid battery. You can upgrade it for 12-volt lithium for $$$. They haven't engineered away the separate 12-volt battery to integrate it into the car's main battery pack for some reason. Maybe they can't? who knows.
@@SiuLeung Tesla has switched to Lithium Ion recently to replace the lead acid batteries. I believe the new battery is a nominal 14.4v. There's still too many legacy systems to go to 48v yet.
The American RWD ioniq 5 uses the same exact tiny frunk, despite having much more space underneath. The European RWD frunk is substantially larger. The reason for this is regulatory. All American cars with inclosed storage above a certain size must have a internal release mechanism so a trapped person can get out. Hyundai did not want to add a extra mechanism to the hood, so they closed the space off and wasted it.
I believe a few more tutorials and I am ready to apply. haha You guys are all excellent teachers. Sandy must be an awesome guy to work with because he has an amazing team!
Frunks always seem to be a big deal to people.. I never even use mine. Just throw stuff in the back seat or trunk. I'd rather see the space under the hood used for other things. I find it annoying when they cram everything in as small of a space as possible. I find being able to fix a part without taking half the car apart has value. Who knows what engineers could use all that rarely used frunk space for....
I've started my frunk more for groceries lately, but even when I didn't it's still extra storage space for things like wiper fluid, charging cables etc.
As a daily driver (commute car) I suppose the frunk does have limited utility. But when we travel, it becomes a very important storage location. Coming from a Range Rover, I can carry more cargo in the little Model Y. Absolutely a brilliant design and it's more comfortable/fun to drive.
What other things? That's the deal-evs have fewer, smaller components, but the designers are lazy and don't arrange them logically to offer space to the owner.
I Guarantee owners of this EV will pour windshield washer fluid into the coolant tank with the blue fluid. Having the washer fluid tank next to the coolant tanks is an invitation for bad things, expensive things...
I love the way Cory and Jordan talk about engineering details in a way that an average person can understand. Regarding the frunk, in the U.S., the RWD and AWD version have the same small frunk. Speculation is that Hyundai didn't want to spend the money to include an under-the-hood child safety release which would have been required for a larger frunk. Can you comment whether that is a real requirement?
A lot of the HVAC system is in the engine bay which frees up passenger space by having a smaller console. That was a design/engineering decision. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0zM3EdnqRZg.html is a video of Hyundai engineers discussing the development of the E-GMP platform. I don't mind a small frunk if it gives more cabin space. "do you want cabinets or a bigger house?" was one of the questions the engineers asked.
I'd die for a cabin filter that easy to change, on the Model 3 it's a nightmare, especially on the RHD model as the dead pedal is in the way. You have to take various trim pieces off from the side of the center console, move some HV heater wiring, then try to somehow get the filters out from their gap with the dead pedal blocking part of the gap. Horrible placement for it. :)
Ya, would have loved the easy replacement on my Model 3 and I'm in a LHD version. I can't imagine the RHD version. Must be a complete nightmare. If Tesla designed it better with no moldy smell it wouldn't be such a big issue.
Not a nightmare. I can think of TONS of jobs on my ICE car that are a genuine nightmare. A filter change in my RHD model 3 takes me around 10-15 minutes, (or Tesla mobile will come and do it in my garage for around AUD$100.)
@@paulaxford6754 Yeah it's not actually a cult, M3 owners are pretty upfront about the actual problems, like the wiper AI and the App linkage time and the latest UI!
Sandy, Cory, and Jordan, I love your High-Fidelity Videos. Suggestion - Help prospective employees to see themselves at Munro by including a new hire at the end of a video instead of the old hey, we're hiring words. Let them talk about, possibly the product at hand (even another project not featured but nonetheless important) and maybe a little about their background.
@@MunroLive Your welcome. Since RU-vid is pushing their 'Shorts' format, you might just make the new hire video 'spots' a RU-vid Shorts? Also, produce them for TikTok?
RWD models have a larger frunk in the EU, but not in the US due to regulatory reasons (no safety release from within the frunk). Keeping the frunk small (or divided in the case of Mach E or Polestar) ensures nobody can climb into it.
Wow it is only 57 litres or so. Only babies small enough to put in there wouldn't be able to operate a switch anyway... But I'm quite happy with the larger frunk on my RWD Hyundai. Would still be eager to trade it in for the larger battery and 2 years free fast charging people in the US are getting...
@@bilgyno1 That's the point. A child old and large enough to open the hood and climb in won't fit, and if the space were larger that child would be capable of identifying and pulling a release.
Cory and Jordan - super appreciate the in-depth and objective view on Ioniq's 5 hood or under the hood :) It would be interesting to consider an objective look at ID.4 and comparison to Ioniq 5. Since both are representing the innovation by "traditional" manufacturers, and both of these cars have a very similar target audience of drivers... Thank you and keep up the good work!
Not sold , saw a towing test on a Rivian , worked out to about 30 miles of towing a truck on a trailer before dead battery. Lithium batteries are 70-100x the weight of equivalent gasoline power output.
#PROENGINEER (ref: Cad Software, PTC/Parametric Technologies Corp circa 1995, or at least that's when i learned of it, think it came out earlier though)
But the example given seemed a bit pointless. A thinner cooler may be fractionally cheaper but provides no other value. I expect they design to a common environmental range for all markets.
wow great review of this car. a lot of interesting things going on there. keep in mind EVERYONE NOT EVERY CAR / TRUCK IS A TESLA. ( I HAVE MY OWN OPIION ABOUT THAT COMPANY) I did learn a lot from this. thank you so much..
What I see is engineering time spent in making the system easier to work on. I feel that Sandy goes a bit too extreme on the manufacturing cost as the be all and end all. For instance I think the molded hoses with proprietary ends is crazy. It means with any leak you have to go to the manufacturer to get that hose. What if you are in a part of the country without a dealer? An ICE car you can generally go to any parts store and get a hose. I probably have enough bulk hose in my garage to fix most ICE cars for a lifetime.
That style of hose is commonly seen on many ICE vehicles as well. A lot of European cars and Fords use them. Likely less problematic in an EV due to the lower coolant temperature not cooking the plastic as much.
The remote reservoir on the brake master cylinder is a vast improvement on my Hyundai Getz which has it under the scuttle panel with a 20mm gap above the filler neck... Luckily there's a mass produced S-shaped funnel that fits int he gap.
I think videos where you clearly compare parts to that of other car makers would be interesting and great for the viewers. Honestly would also bring in a wider audience. The kind of audience that don't already know a great deal about car manufacturing
Interesting insight to the Ioniq 5. I have an Ioniq 5 Limited AWD, and the problem I am having issues with the A/C heating module. For lack of a better description, it has died after 600 miles and 4 months later still no sign of the part(s) needed to repair. I am now only driving the car in the early morning and the late afternoon/evening to tolerate the heat in southern California. From the various Ioniq 5 forums, I am not the only one having issues. I have contacted Hyundai and unfortunately the supply chain issues is causing this issue, and the newness of the car for technicians working on it.🤨
Really enjoyed your review, I was hoping to get a close look under the hood. EVs are evolving quickly, getting better all the time. I can hardly wait to test drive the Ioniq 5.
Interesting point on the parametric design. I guess its less of an issue to have dissimilar parts if the parts themselves are essentially the same thing, but with a variable tweaked.
What a remarkable difference between this super-clean and organized "engine" compartment vs the Ford Mach-E's nightmarish, rat's nest of components and tubing.
Although it may be good for the manufacturer, I'm not entirely convinced cramming as many sub systems into one single unit is necessarily a good thing for the consumer. Reason being the lack of resources to do component level repair means when one single component fails, it means throwing out whatever module it's in so the more modules that are tied together in a single unit means more things have to be replaced = more $$$ out of your pocket. At least with multiple separate modules making up a system, you don't have to throw out an entire system as one very expensive non-serviceable. If cars were built to last it would be fine but they usually aren't. For example, combining the ABS system with the master cylinder seems like a good idea until a soft foot pedal caused by a worn 25 cent seal in the master cylinder means that instead of just replacing a $150 master cylinder you are now also replacing a $1500 ABS system that is perfectly fine. The seals in my master cylinder are starting to bleed pressure and I am very very pleased it's a simple $150 part swap I can do myself in the driveway.
Sure, compared to Tesla they have a long way to go, but I think compared to many other manufacturers this is positively minimalist. And in a rear wheel drive vehicle I think it would be dramatically simplified. Im on the fence about those quick connect hoses. My Saturn had similar connectors and the rubber seals rotted and they were just leaking coolant directly from the fitting. It was an easy fix with rubber hose and a pipe clamp, but it was still extremely difficult to *remove* the old hoses even though they were leaking. Hopefully these have been greatly improved in the last 20 years.
@@jamesvandamme7786 Well... Servicing a Tesla is not easy. Not at all. Tesla does everything to prevent it. And their system is not that reliable, like now when people heat pump compressors gets damaged by Teslas bad design and the system fail to give heat in cold weather.
@Sandy Munro, your guys should get a laser pen so that when they are filming they can show what they are talking about with the laser dot rather than just pointing with their fingers.
Having the power distribution system hard mounted and not integrated into the drive unit underneath is IMO a great design choice to make service easier. A bit more expensive to manufacture since there is an additional mounting step, but way better for the customer who will get charge for the service IMO.
Seems a bit odd to directly compare thermal systems when Hyundai is providing additional functionality. Namely, voltage conversion between 400 and 800V and also including the sizable onboard inverter. Tesla's design elegance is state of the art for sure, but the products aren't apples to apples.
There is nothing in the extra complexity in the thermal system that is required to enable those additional features, so I think the comparison is fair.
Elegance can have different meanings as well. i did not find the Ioniq 5 under hood inelegant by any means. The Model 3 on the other hand just looks like a mess even if it has shorter and less hoses.
@@Wankidy but these are new ground up ev designs. I think it’s inexcusable. I’m curious to find out what’s under these long hoods. At least w the id4 and Ioniq, they have short hoods, so it’s some what justified.
re: "What I don’t get is why EVs with long hood don’t have a frunk, eg lyriq, eqs, iX, etc." no worries, they're NOT Porsches. want an original frunk...? buy a 911 (which is the "cache"/USP everybody's looking to imitate).
While it is posit that EVs should have lower maintenance cost and better long term reliability, the amount of hoses, clamps and pumps in the various cooling systems can be a concern. Good to see the changes Hyundai has made generation to generation. This also looks much improved over the MachE which had 35 thermal hoses and was covered in a previous video
True, but from an ICE perspective consider the far lower temps and pressures involved. The Ioniq 5 looks much the same as my Kona but with the replacement of conventional rubber hoses with plastic snap-on.
2 loops That would explain the "high temp" and "low temp" readings seen on OBD2 scanners? Those temps seem to throttle charging below 20°c and above 45°c (ish)
I think it has something to do the cooling fluid completely flows in curves from front to back through the battery while e.g. ID.4 has a dedicated fork for each module from the main flow through the middle and gathers at the outside again before returning.
Cory made a good point and it may be that what the battery wants is sometimes at odds with what the occupants want. I had thought it was to minimise volume of the expensive and perishable non-conductive coolant outside the battery loop but I think Cory was right.
How much reskilling do current car repair shops need to do to start working on these? Do they need to hire totally different people or can they upskill their current workforce?
See bad part. Turn bolts on bad part counterclockwise. Toss bad part. Put new part where bad part was. Turn bolts on good part clockwise. Not much difference. 🤣 But seriously, most of the car is the same whether it has a fuel tank and engine or a battery and electric motor: tires, wheels, suspension, brakes, steering, and everything in the interior. From a service perspective, most of the difference between and engine and a electric motor is just fewer mechanical parts, and added wiring. If you can't retrain from engines to EVs, it's probably time for you to retire.
Awesome video. Both of you are starting to insert some opinion that sas prev sandys skill. This opinion and your accuracy is what makes the content next level.
The RWD model does have a deeper (and actually usable) frunk but it depends on the market. Some states, and in Canada, law prohibits the large frunk even on RWD models because there is no in-frunk hood release button. So, when I receive my Ioniq 5, I’ll actually have to fabricate myself a large frunk because Hyundai dealers I’ve contacted refuse to seek me the frunk assembly without providing them with a VIN.
Some ioniq 5 owners investigated importing authentic European frunk and installing them themselves. Unfortunately the quoted price is $2800 for a glorified plastic box that's pretty standard for parts costs of a brand new vehicle. It should drop in the months and years ahead. I expect 3rd parties will make options available soon as well.
@@gelu88 sounds like this was me. I actually found a US place where it’s listed 575USD but still wants a VIN and refuses to just sell it to me. Been documenting this on a FB group.
If only to be an engineer! Only 2 places on the planet anyone who is truly passionate about their craft would want to go.. Munro or Tesla. Period! Honestly you guys rock…. As more of your team gets introduced here is is clear, they love what they do, they love the people they work with and each takes enormous pride in carefully presenting the perfect mix of detail for your audience. You guys described parts in the recent breakdown as a “symphony of engineering”. Let me say this, your team is a symphony of passionate professionals. Thank you again for all that you do to educate your followers.
I do like the placement of the cabin pollen/air cleaner and as mentioned you need to be a contortionist to access it in some vehicles (my Citroen C5 is one) and on a Honda Accord 2004 you have to remove the glovebox lining which isn't too bad. I just wish I had a CV to email.
The battery is not AGM guys - CFM50L is a traditional ICE starter battery, optimised for the high current surges needed to start ICE motors (CCA 550A rating). This means spongy, high surface area plates but with thin lead coatings. This is the wrong type of battery to fit to an EV, which never needs the starter cranking amp. It should be a deep cycle type, with thick lead plates. These can't provide the high surge currents so well, but can discharge at a low, steady rate for a much longer long time. Fitting the wrong type of batteries may be contributing to 12V batteries going flat in some Ioniq 5s.
Interesting to note is that the thermal system seems to have issues regarding the cell temperatures. The difference between the minimum and the maximum cell temperature often hovers around 10C, sometimes more, especially when charging. This reduces the window of optimal charging speed quite a lot as it begins charging with some cells too cold and different ones can become too hot, even in the same charging session.
@@AudiTTQuattro2003 Not this video but from other YT videos highlighting the charging issues when the battery is cold. Hyundai have no pre-conditioning heating of the battery while driving to a Level 3 charger. Hyundai plan on a software update in spring 2022.
Coolant flows in curves from front to back of the battery, so modules further away get the heat from the ones in front, this might explain the difference.
Wow , very informative and well done . Thanks Guys . If I had the know how I would love to work for Munro And Associates , the future for Evs is looking very bright indeed .
And that is exactly why the current group of big auto manufacturers are so far behind Tesla. Too damn many models with only subtitle differences. Tesla is defining the new paradigm.
Q: What's your assessment of that? A: better to "float" than eventually to "rub through" from vibration (even from the stabilizing clamp or zip-tie itself).
I get the impression through some of these videos that you guys don’t know much about the inner workings of these cars, just if things look visually appealing over all and cues from a few organizational patterns. But seems sort of high level low info stuff.
I think they know how they work but it would take forever to delve into all the fine details. What they should do is invite the manufacturer's engineers in to explain the reasoning.
Although the heat exchange system of Hyundai Electric Vehicles is complicated, the heater efficiency has always been the highest among electric vehicles. Winter mileage compared to battery capacity has always been top. This has been shown in various electric vehicle tests, and in actual mileage competitions, the mileage compared to the battery capacity is the longest.
Why don't they use the heat pump to warm up the battery? Is it even possible? Do Tesla also has a PTC heater to warm up the battery? You guys are awesome, keep the videos coming!
Tesla use the motor to warm the battery, essentially a resistance heater. But it's a good question as to why the HP isn't used. The Kona PTC is 2.2 kW for the battery.
Possible under some conditions, yes, but I think you will find that the circumstances where the battery most needs to be warmed (car sitting outside in very cold weather) are the same circumstances where a heat pump would have difficulty extracting much heat from the outside air. If you are just going to short-circuit the cold and hot sides of the heat pump together in those conditions (Tesla!!) or actively drive the motor in an intentionally inefficient mode to give the heat pump some input heat to work with (Tesla!!) it begs the question "why bother", doing that is no more efficient than using resistance heat.
Tesla P85 driver 7 years, 120,000 UK miles, test drove the IONIQ5 yep its a credible EV but for me my 2012 design Tesla still the better car. Interesting to see credible choice on the EV front.
As an old auto tech that argued with many, MANY, service managers. If the brake fluid reservoir has a sensor in it, you DO NOT fill it up when servicing the vehicle, after checking the brakes and for leaks of course. That sensor is there to let the run of the mill customer know his brakes need checked and will not come on if you keep filling the reservoir every time the vehicle is serviced. Of course these same managers have asked me " Why didn't you check that first?" multiple times after chasing down and diagnosing a particularly hard problem. They all got the same answer..."Because the problem is always the last thing you check." Idiots.
