Differences between the Hyundai Ioniq Electric 28kWh and 38.3kWh models 

Glad you liked it. There's quite a few Ioniq videos on the channel, see ru-vid.comsearch?query=ioniq Also over 450 EVs on the channel too..ru-vid.com

That is not completely right. Things are often confused here that were different at the beginning. When the Ioniq facelift 38 kWh came out there was a problem with the BMS, on the first models. These first cars were tested everywhere back then. An average charging speed of 10-80% of 34kW was determined. That was of course a step backwards compared to the 28th Battery pack. The 28 kWh battery charges at an average speed of 64kW from 10-80%. But the old BMS and batteries were later replaced during a recall. There were also always BMS updates in the individual production years. However, these updated IONIQ 38 kWh were no longer tested at that time, but I have a newer BMS in my late 2021 model. It still doesn't charge above 50kW, but keeps its charging speed above 40kW for longer. The old BMS has already reduced to 35kW at 53% and from 68% it was then reduced to 25 kW. With the new BMS this no longer happens so much. At 68% I still have 35 kW and at 75% it throttles down to 25 kW. This is why you usually charge from 10-75% with the new BMS. With the new BMS you have an average charging speed of 40 kW from 10-80%. And yes, I know that it still doesn't come close to the 64 kW of the 28 kWh battery, but it's not as bad as people remember from the old comparison tests. Of course also an improvement of 6kW average charging speed from 10-80% compared to the first 2019 models of the IONIQ 38kWh.

Could you go a bit deeper on "everywhere"? Recharge speed is not I guess

Thank you

Thanks. Glad you like them.

Is there? Maybe you can share a video?

Touchscreen controls on some of the chinese cars are used for even basic drive functions, which seems crazy. I really like analogue switches and knobs for functions that you are going to use all the time. Touchscreens or haptic buttons are only good for those occasional settings only IMO.

Thank you! 😃

Thanks. Not tried the Corsa-e yet. I guess it could be a while yet until I'm buying these in.

No, its the lens shield. Needed to protect the lens from water as I'm often filming in the rain.

You can look up servicing costs here onlinebooking.hyundai.co.uk/ Use the number plates of these vehicles in the video. The servicing is annually or 10,000 miles. The fourth service is expensive as it includes a coolant change, but all other services are pretty cheap.

I own a 28kWh Ioniq and but have never driven a 38kWh version long enough to require DC rapid charging. A lot comment on the speed of the rapid charging, but I'm less worried about it. In reality, you rarely charge at maximum speed anyway and there's many factors that can effect the charge speed at the given time. Plus if you can charge at home, DC charging will be a very small percentage of your charging. Personally, I wouldn't worry about it. Go with the larger battery and enjoy the longer range. If the 28kWh didn't charge so fast (and faster than Hyundai quoted) then it wouldn't have been such an issue.

@@GoGreenAutos That makes a lot of sense, and it's the charging time that is important, not the speed, which for me will be about 10 mins on the return journey, so not that bothered. I was looking a ID3/4's and Model 3's up to this point, and whilst they are different cars of course, you cannot overlook the value you get from the Ioniq, in terms of price, equipment and efficiency......great channel btw, and not too far from you in West Oxford, so good to know for the future!

@@GreggCastree Yes the Ioniq is fantastic value. You get a lot of car and equipment and its sooo much better than you'd expect, yet sort of goes under the radar.

There’s more data accessible via the obd2 interface & app

The 28kWh has forced air cooling (which does an excellent job) and the 38kWh has liquid cooling.

A lot of vehicles have had these for around 5 years or more. Even the Peugeot iOn has one. In an accident, you can press the button to speak to a call centre and they know your location and can call the emergency services.

@@GoGreenAutos thanks. I assume that’s a rapid charger so a fast charger would be longer. Sorry I’m just learning about this.

@@davidadams5116 Yes. The terms "rapid", "fast" etc can be misleading. Far better to just remember DC or AC power. DC (rapid) charging is via public chargers which are huge 6ft cabinets. The actual charge rate is dictated by the car. The Ioniq 38kWh charges at 44kWh peak, so takes 45 mins to go from 0-80%. When charging on AC power, it will take 6 hours (0-100%) if using a 7kW wall charger or in other terms, it adds about 28 miles of range per hour of charging. If using the portable charger on a normal mains socket, charging is limited to 10 amp (2.3kW), so it adds about 10 miles of range per hour. Or a 0-100% charge will take 19 hours.

@@GoGreenAutos thanks for that perfect answer

Not coldgating, its the battery that makes it charge so slow. They used the same pack as the Kona 40 kwh. It also charges slowly. It has something to do with the density of the battery pack. They had to keep the temperature down, if it charges faster it would been too hot.

An Ioniq 38kWh would do your 130 miles VERY easily, even in the coldest winter and on the fastest roads, with no charging needed. In fact, even a 28kWh would do it, but you'd have to drive pretty economically in the winter as it would be tight. Using all the pack as zero effect. Lots will tell you otherwise, but in the real world (I see lots of used EVs), its not measurable. The BMS looks after the battery for you, so let it do its job. You charge to 100% every day and it will be fine. Our Ioniq 28kWh has been charged to 100% every night and its now done 102,000 miles and the battery is still as good as new with no range loss whatsover. Plenty of videos on this here www.youtube.com/@GoGreenAutos/search?query=ioniq

The reality is that for a 200 mile trip, the older 28kWh model could be slightly faster as for that distance, both the 28 & 38kWh would require only one charge stop. With the 38kWh model, the range you can achieve with a full battery at different average driving economies are: 6.0 mpkWh (super efficient city driving) = 228 miles 5.5 mpkWh (efficient summer driving) = 209 miles 4.5 mpkWh (average driving) = 171 miles 4.0 mpkWh (efficient winter driving) = 152 miles 3.5 mpkWh (very cold winter driving) = 133 miles With the 28kWh model, 6.0 mpkWh (super efficient city driving) = 168 miles 5.5 mpkWh (efficient summer driving) = 154 miles 4.5 mpkWh (average driving) = 126 miles 4.0 mpkWh (efficient winter driving) = 112 miles 3.5 mpkWh (very cold winter driving) = 98 miles

@@GoGreenAutos Thanks Matt for your informative reply. My 200 mile journey will be mainly motorway so possibly another stop or two. I'm leaning towards a 28kWh Ioniq.

Yes it does, for both AC and DC charging.

@@GoGreenAutos thanks for the response 👍

You say the charging speed makes such a difference but what if you have to wait because all of the chargers are being used ? (This has happened to us a lot) You would have an extra 50 miles left in the new 38kwh ioniq so you could drive to the next charger because let's be honest your not going to drive the full 170 miles without needing to stop for the toilet or a walk or a Greg's.

my 2020 gets 325 or more in summer time driving

km, presumably..? @@user-yc5de5pr7i

I don’t have one but I’m pretty sure the new one can do over 200 miles if it’s warm

Still on the UK Hyundai website.

Don't know. How long is it? I suspect so. Have a look at the brochure here as I suspect the dimensions are in there.... www.gogreenautos.co.uk/buyers-guide/manufacturer-brochures

No. I drive a classic Ioniq and also play golf. I always fold the seats for golf bag

Heat probably, because they've squeezed an extra 10kWh capacity in the same size battery enclosure. This is why they also added water cooling on the 38kWh model. But you'd have thought with the addition of water cooling, they'd manage to keep faster charging.

I will do when I get in another 38kWh Ioniq. This one has sold now, so I'm not going to take it back out. But the headlights on the 28kWh are excellent and LED, so I can't see its a big issue.

@@GoGreenAutos ah right I see, no worries. I think it was just the main beam on the older car that people complain about as I believe it's halogen.

@@mrmuds8624 Yes it is. Dipped is LED and main beam is halogen. The main beam gets drained by the brilliant white LEDs so doesn't feel much of a benefit. Its not that its no good..its just because the LED dipped is so good.

@@GoGreenAutos Exactly ! Even Byorn Nyland has mistaken a Hyunday Ioniq Classic (driving from the opposite lane at night) with a car with Led Bar in one of his videos. On slow motion replay you can see it is just a regular dipped headlight beam 😃

Very well. I've got a video coming on this channel in 3 weeks time about motorway/highway driving efficiency in these Ioniqs.

ECO mode can help some drivers, but to drive an EV efficiently, the drive mode doesn't matter. Its all about how you press the accelerator pedal, just like in an ICE vehicle. So light acceleration and light deceleration, using the regen only to slow you down and not touching the friction brakes. Coasting is key, which is very easy in the Ioniq has you can set the regen to 0. Drive as if you had no brakes and it will reward with great efficiency, just like it would in an ICE vehicle too.

@@GoGreenAutos would you use regen in town only and try to coast as much as possible on faster roads then?

@@iainmorrison1592 For best efficiency, you adjust it depending on road speed, gradients etc. But most people probably don't bother. Once you're used to it, you'll probably keep regen at its maximum for all driving and then just feather the accelerator pedal very lightly and rarely take your foot off it completely. You can achieve the same efficiency if you get good at this and holding the accelerator at the point it coasts. You use the power meter to show you this. But yes, generally, 0 regen when on fast roads like motorways or when taking advantages of gradients and max regen when town driving.

Just checked this again using the Hyundai sales brochures at the time and the weight difference between the 28 and 38kWh models is 100kg. I'm not sure where I got the 55kg from at the time, but the kerb weights in brochures, V5, websites etc is often wrong. I see mistakes so many times in manufacturer's own spec lists and brochures. Anyway, 100kg seems about right. That will be due to the 10kWh of additional battery cells and the extra coolant.

Thanks for responding Matt! Sorry to be a pedant, but I actually meant between the trim levels within each model - you mentioned that the weight between the 28kwh Premium and the 28kwh Premium SE varies 55kg whereas between the trim levels in the 38kwh it's only 3kg? Hardly a riveting enquiry but just interested . . . my mind tends to focus on the most obscure facts!

@@howardfrancis1292 Oh right, sorry. I should have watched my video again before responding. The 28kWh models have a weight difference of 55kg between the Premium and Premium SE specs. On the 38kWh models this is 48kg. So maybe the brochures were incorrect at the time of making this video. Its something I see a lot. At least the figure seem correct now.

Not on these electric models - the same.

Oh i thought it was, dont know where i got it from.

@@Mr_Seppo The Leaf has a foot brake on the floor.

@@Mr_Seppo Hi i think the Hybrid and the PHEV model of the Ioniq might have the old FootBrake. The Electric model is much higher spec with Electronic Hand Brake.
