Hyundai Ioniq 28 kWh battery degradation after 162k km

[@MichaelMrak]

I can really confirm this. My 2018 Ioniq Classic has now covered 160,000 kilometers and its range still feels as far as it was at the beginning. That's why I've kept this car and will continue to drive it for many years. I've also sold my 13-year-old diesel and have now equipped myself with an Ioniq 5 Long Range. Thus, I have completely switched our household to electric vehicles.

[@IanMcc1000]

I think a lot of these car batteries will do the mileage. What will be most interesting is to see how time affects degradation, since charging and discharging seems negligible if done within certain parameters. A 6 year old Ionic is holding up well, but I wonder what a 10 or 15 year old one will be like.

Great to see that you still do videos in 2024 about Ioniq classic! Best greetings from Germany

[@evdabbler]

Coincidentally I just released the results for a study of degradation on 20x Ioniq 28kWh this morning too. These have anywhere between 40k and 160k km on the odometer. Many of the contributors to this crowdsourced exercise will have been inspired by this channel to buy the Ioniq classic in the first place. And yes impressive results on the degradation but also very consistent across that sample, which is great!

[@ashton9699]

If only I knew of your crowdsourced test, as before battery replacement my Ioniq 28kWh at 145k km was at 33% degradation. I still have the proof if you would like.

[@Tsimi1234]

Lmao! Calling something with a sample size of a whole 20 cars a "study"! Ahhahahhahah Also 160tkm on the odometer is classified as 'everything necessary should be completely functional' in used ICE standards by consumer protection laws in my country. Only well after 200tkm should there be major issues expected, so your "study" is useless for a normal consumer looking into longevity of a used EV.

[@evdabbler]

@@Tsimi1234 glad it made you laugh, i see twenty being better than a sample of one or two and a starting point for more. In fact we've now doubled the sample to 40 (wow!!) and participants remain welcome.

Very nice. Hyundai should bring this exact design back and place a larger battery in. They could offer 40 and 60 kwh options and sell it for cheap given that it requires no new engineering. We need less self driving and laser lights and more affordable, reliable options! Call it just Ioniq and sell it!

Glad to see this Bjørn, gives me confidence to hang on to our ultimately quite low mileage 2020 Ioniq 38kWh as long as we can. Such lovely car, our first ev, couldnt bare to drive anything else and not see the low miles per killowatt hour! Rarely get less than 5m/kWh even in winter, now the weather is warming over here in southern uk we're back up to over 6m/kWh. Sorry I cant do the conversion and that would be my request for your videos, as you're such a number Ninja could you do the conversion when you tell us of consumption? I'm number blind and Wh/100km does not compute in my poor old brain! Cheers Bjørn, i dont comment often but love your videos my friend. 👍👏

[@yt-viewerfromger320]

In Germany we usually use kWh/100km for ev consumption. Björn prefers Wh/km. If your Ioniq consumes 10kWh/100km then it's 10.000Wh/100km which equals to 100Wh/km, a real good number. My brother's first ev was a classic Ioniq and his car only needed around 10kWh/100km (or 100Wh/km). Your Ioniq drives around 6m/kWh which converts to 6x1,60934=9,66km/kWh (rounded). If you devide 100 by this number: 100/9,66=10,4 (rounded) you'll get the number of 10,4kWh/100km or 104Wh/km for your Ioniq classic with 6m/kWh milage.

We have this car here in Ireland. Bought it in 2018 and drove it in Ireland, UK and France. Barely a moment’s trouble with it. It has about 145k kms on it now, and we haven’t noticed any real drop-off in available range (we’re not paying close attention, but it gets all the way to the chargers that we use when travelling to Dublin and all the way home just as in the early days, so it seems fine). Except for the battery, the car is out of warranty, but we’ve only been stung with one repair, a tyre-speed sensor for €400 IIRC.

[@ashton9699]

I have 2019 28kWh Ioniq and somehow it was the exception. At 143,000km the batteey was already degraded to only holding about 16.5kWh (66%), confirmed with multiple degradation test using your method. The problem is that SOH% on these cars is completely inaccurate to capacity, even with such severe degradation, SOH was still reporting 84%, and so it was extremely difficult to get Hyundai to honor their 70% capacity warranty. Ended up being a one year long fight. Overall the batteries in these cars are extremely reliable, but buyers should just beware that in the rare bad luck case, the fake SOH may allow Hyundai to try and scam you out of warranty coverage.

[@SICHTKRAFT]

I am sorry to hear that. I would instantly go to court if Hyundai would try that on me. Calculating remaining capacity with the Ioniq 28 is almost hilariously simple, so no discussion needed. I have to believe in any litigation made up fairytale SOH number the car reports itself must be absolutely worthless. Imagine manufacturers of other product types would try this! Or even cars... imagine the 300 kW sports car only produces 100 kW on the dyno. Who in their right mind would argue that the internal system of the car reports 300 kW so it must the correct?

[@w0ttheh3ll]

The SOH is not necessarily fake - SOH has nothing to do with kWh. Per the most common definition, SOH is Ah/Ah_new. It is simply the wrong metric to use for a guarantee, because the driver doesn't care about SOH.

[@TehOnlyAnd1-pw8ci]

I assume you checked cell voltages at low SOC - were there bad cells?

[@ashton9699]

@@w0ttheh3ll no, it is not. It is not other EVs like Leaf. SOH on these early Korean EVs is just a calculation based on cell balance/voltage deviation. A heavily but evenly degraded pack will still show good SOH.

@bjorn: can you please explain how you get or calculate the cycles number in your degradation google sheet? In this test you state 1620 cycles which results in 100 km/cycle (with odo 162.000km and calculating odo/cycle to get km/cycle). In your other 3 classic ionq degradation tests you calculate with 160km/cycle. Sounds inconsistent to me, but i do not know how you get the cycles number.

[@florentcoste]

Resting voltage. As it drives it dips. When it stays it goes up. Bms is smart otherwise your state of charge would go all over every second while you're driving if it relied solely on pack voltage.

@@pavelblaha5243 The BMS likely does two things to do that: it does coulomb counting (integrates the current over time to come up with an Ah differential), and it guesstimates the internal resistance of the battery and uses that to compensate for the present load which allows it to estimate the resting voltage if load was taken off from the battery.

Measuring SOH on these cars is really hard and requires more driving and proper charging. I myself have Ioniq 28kWh with 41k ODO and when I bought it, it had 100% SOH. Now after 5000 kilometers I did not do full discharge and charge to 100% and it showed me 89% SOH. It was able to use only 22,5kWh from the battery. After lots of hours reading discussions and threads on forums regarding battery degradation of these cars, I am performing battery calibration test (slow discharge and slow charge to 100% several times), and it is slowly getting back to 100% SOH. Last time I was even able to measure getting 28kWh to the battery pack (excluding 11% losses on AC charging).

[@bjornnyland]

You can't trust the SoH variable in Korean cars.

[@Ferdomravec111]

@@bjornnyland Thats right. But also measuring kWh and degradation based on battery percentage used, consumption and kilometers driven can be misleading until you are totally sure that car is giving you whole capacity it has. In my case it gave me less available capacity until I calibrated it (although it COULD store more). You can rely on your results if you know that the car was regularly charged to 100% and discharged to 7 or less percent once in a while. There is a chance that this car can give more and the degradation is actually lower. I am not trying to disregard your results by all means.

I have a question regarding my electric vehicle, a 2018 Hyundai Ioniq model. My car has driven 80,000 miles so far, and I use it daily, charging it at home using slow charging. Recently, I checked the high-voltage battery, and it showed excellent condition: SOH (State of Health): 100% Deviation: 0 After that, I traveled a distance of 900 miles, using DC fast charging five times during the trip. About a week later, I checked the high-voltage battery again and noticed a drop in battery health: SOH: 96.1% Deviation: 0 The following week, I used the car normally with AC slow charging (16A) and checked the high-voltage battery a third time. The readings were as follows: SOH: 94.5% Deviation: 0 Isolation: 1000 It's worth noting that all 96 cells had equal voltage readings, ranging between 3.86 and 3.88 volts. Professor, if you could please advise, What procedure is typically followed in this case? The car has not registered any error codes, and using the Autel diagnostic device, I accessed the "Special Function" menu, where I successfully performed the "SOC (State of Charge) Calibration." However, there is no "SOH Calibration" feature available.

[@robinverdegaal]

@bjornnyland do you know anything about ICE degradation? This efficiency loss over distance driven seems to be exclusively discussed in the context of fully electric cars, but I've been wondering how much ICE cars are affected due to wear and tear of internal components. We know they sometimes lose a significant amount of HP during their lifetime so I'm pretty sure efficiency loss could be an issue as well. I've been searching the web for answers but I can't seem to find any significant data, or even any data, regarding the matter. It would be very informative to have a comparison of identical ICE car couples with 100.000 km difference on the odometer tested for range per liter of fuel. Let's say two 4 cylinder and two 8 cylinder petrol cars of different car brands, just to have some real life benchmark to compare fully electric cars to your real life EV test benchmarks. Your 1000km test format could be a very doable way to retrieve that kind of real life information. Maybe in a combined effort with another tester, so it would be possible to drive the younger and older car in the same weather conditions. Maybe some testers would be interested in finding out, or maybe some have already done that and my Google Fu is lacking?
