Hyundai Ioniq 5 DC Fast Charge Test

We take a 2022 Hyundai Ioniq 5 with the extended range battery pack and record three DC fast charging sessions, (two from 10% to 80% and one 0% to 100%) on 3 different charging stations to see how well it will charge in cold weather.
Hyundai advertises that the Ioniq 5 will charge from 10% to 80% in only 18 minutes, but that's in ideal conditions. We wanted to see what customers can expect in colder temperatures when the battery won't accept its full charging power.

Launching without preconditioning feels like an obvious mistake, but honestly I'm surprised at just how well it manages to charge despite being cold gated. 30 mins for 10% to 80% in below freezing weather is pretty impressive, especially considering the lack of preconditioning. I'm excited to see what this thing can do in the cold weather with proper battery preconditioning.

[@klossfam]

In sync with my experience in the cold but just road tripped our I5 Limited AWD to FL. Awesome advertised charging speeds in 70-75F with a warm battery and ripped off 16-86% in 17 mins on an EA 350. Many similar results also.

The consistency of the two charging graphs, superimposed, was impressive. So many times, I’ve watched You-Tubers rag on chargers for not passing high-kW to batteries… maybe the charging control algorithm of the car’s computer is more often the culprit, than the charging station!

[@StateOfChargeWithTomMoloughney]

Yeah, quite often the people complaining don't really understand how charging works.

[@SirHackaL0t.]

Some chargers seem to do a better job than others. I’ve had some in the UK that supposedly give 120kW but gave 20kW. I then moved to another type of charger and got over 80kW.

[@carsonassociates3263]

@@SirHackaL0t. But isn’t the state of the battery changed (“conditioned”), even by a few seconds at 20kW? Upon connection to the second charger, perhaps the car’s software then determines it’s able to accept higher charging kW, and does so? It would seem that a reduced charging rate is the prerogative of the car, and not the charger.

[@SirHackaL0t.]

@@carsonassociates3263 A lot seems to depend on how many amps the charger can deliver to the car. Electric Highway seemed to be only capable of 20kW. I did leave it on the charger whilst I used the loo and it still only gave 20kW. Something in the charger was limiting the supply to the car.

[@naughtysauce4323]

That's if you can find a station without a wait time. Before CCS chargers were almost always empty in my area while the Tesla superchargers were the ones w/ the long wait times. Now that a lot more people are buying EV's, I'm starting to see long lines for the EA stations, sometimes 3-4 cars waiting, now imaging that's 30 mins a vehicle that you have to wait if they're only charging up to 80%. They need to vastly improve charge stations and start adding chargers at gas stations every 4-5 exits.

[@arti22live]

preconditioning is a must have ,I've done both tests on my tesla 3 performance, it really sucks without preconditioning!

[@yt551217]

Appreciate your efforts. Got my new Ioniq 5, SE AWD 1 week ago and am loving it. Of course Hyundai is going to report their 18 minutes in perfect conditions. Maybe would be better to have preconditioning but don't know if that would add expense and am happy my Hyundai was $20k less than a Tesla Y. What concerns me more and I'm surprised you didn't find it troublesome is why are Electrify America 150 kW and 350 kW stations charging at the same speed?

[@bradcooke5383]

Thanks again Tom. It's interesting that this range was very close to Stan's Bolt range with his new battery in the cold. Charging time on DCFC obviously very different between the two models. Another very useful charging review.

[@MachE_Mutt]

Great content! If I ever get delivery of my Mach-E (11/9/21 order date), I had planned to do this test with EA 150 and EVGo 100 kW stations. I've also wondered about network differences so I'm planning an EA 150 vs EVGo 200 vs ChargePoint 125 kW stations. I may also do an EA 350 Signet to EVG0 350 Signet. This will also result in some cost comparisons between per minute and per kWh pricing. While per kW seems the fair way to price, it looks on the surface that the current EVGo per minute pricing will actually result in less out of pocket cost.

[@athanasiospliousis2654]

Nice video. I have a question however. Have you experienced a higher power delivery than ~160 from the 350 kW chargers with another car? Although it is not possible for the user to know there is always the chance that the charger will not give more power to the car although it might be rated at 350 kW. That could be due to many technical reason either from the grid capacity and/or the number of cars charging simultaneously or even cold etc. That is why i asked if another car did get more power at the same more or less circumstances. Thanks.

[@francismarcoux8944]

Do you share the crurent when there is many car charging at the same time

[@newscoulomb3705]

Given the conditions when you were conducting these tests, I'm not sure that Hyundai can be held to that 18 minutes from 10% to 80%, which I would only expect to see under ideal conditions. That being said, there's also a good possibility that the EA charger was only operating as a 150 kW, which could be why the charts would match so closing. At this point, the only 350 kW chargers that I would count on for reliably providing full power would be EVgo's "Ultium Ready" units.

[@TonyPalermolifecoach]

Great video. One question I have and I'm sorry for asking this, if it's already been answered, but I can't find an answer. I've always heard Tesla supercharging or DC fast charging is bad for batteries, so one should not do it a lot. One review I saw said you can supercharge everyday without issues. It's confusing, if you have a video talking about this issue could you please let me know? Thank you.

How does the Ioniq 5 compare to Tesla and Porsche under the same conditions? Especially since Tesla and Porsche have battery preconditioning.

I assume the first two ramps are temperature related and the declines are maybe built in ramp downs at defined states of charge. You should use the OBD scanner.

As someone who would love to have an electric vehicle but can’t yet, it’s fun to learn about the technologies. I was particularly interested in the pre-conditioning feature that does not exist in this car… Yet. I’m thinking perhaps with the software updated could be? Likely this type of feature will become standard very soon in all electric vehicles. They just keep getting better and better. And the charge times are phenomenal! Thanks for another great video Tom.

[@GregTheroneggythetech]

Great test thanks. When you do your next test is it possible to find a 500 amp station I know Kyle has one near him I'd be interested to see how that changes the curve if at all.

[@StateOfChargeWithTomMoloughney]

The two 350 kW tests I did were on 500-amp units. It's not known for sure if EA has limited tome to 350-amps, but that wouldn't matter - this is an 800-volt battery system with a peak charging ability of about 235 kW, so even 350-amps is more than enough.

[@berthogendoorn2133]

Hi Tom the Battery warmer as it is currently is set, only keeps the battery warm when plugged in, so if you are home charging at night it will also do slight condition warming while plugged in.

[@StateOfChargeWithTomMoloughney]

Ok, didn't know that. Then why does the display show the energy used for "battery care"?

[@procekim]

In Europe, we do not have battery pre-conditioning available yet. It will come this year with software update. Did you have winter mode enabled? You should repeat this test in spring.

[@StayConnectedEV]

So I live in the area East Brunswick and used both Bridgewater too.. Ive noticed Electrify America units truly underperforming and youll notice this with other cars. Ive spoken with Porsche owners and Kia and Hyundai all say same thing about these locations. They have been having significant problems and I wanted you to know they have service tickets open on them

[@StateOfChargeWithTomMoloughney]

I have charged there more than 30-40 times with probably 20 different EVs. There have been occasional issues, but overall, it's one of the most reliable EA stations in the area. Quite often when people report issues about slower charging, they don't understand the battery needs to be very warm to accept the full charging rate. I was there last week and a Taycan owner was complaining about this so I showed him how to see his battery temperature (he didn't know how) and his battery was at 60 degrees. The Taycan's battery needs to be at about 92 degrees for it to accept the full charging rate.

[@ArtiePenguin1]

Any way you can re-do this DC fast charging test in warmer weather? Also, maybe you can use an OBD2 adapter to get the exact amps and volts going into the battery. From what I've calculated, the Ioniq 5 and EV6 accept a maximum of 350 A so (at least on EA ABB units) there shouldn't be a difference between "150 kW" and "350 kW" labeled chargers. I'm not sure if the "150 kW" Signet units you have near you output less than 350 A though.

[@StateOfChargeWithTomMoloughney]

I am trying to get another Ioniq 5 to do so.

[@alainamyotte6127]

Hello Tom. Great video on the comparison of the 150kW and 350kW stations. The big take away is that with the current car setup there's no advantage of using the 350 station in the cold and paying more. One suggestion would be to plug in a OBD dongle during the charge. Ready Steady Charge youtube channel has a video of an Ioniq 5 charging while monitoring the battery voltage. It seems that the Ioniq 5 will allow for jumps in charge rate when the min battery temp reaches 15C then jump again at 20C and again at 25C. Those would explain the jumps on your graph. The main takeaway is that the Ioniq 5 needs to add preconditioning for fast charging. I like the idea of having the option of having a button to start it. This way if you're not using the car's navigation you won't miss on the preconditioning. Looking forward to your summer charge comparison. Hopefully they don't have preconditioning by then so you have an apple to apple comparison. Al

[@StateOfChargeWithTomMoloughney]

I doubt they will add it by then, but even if they do, it probably won' need preconditioning if it's 85 degrees or warmer outside.

[@_pehash]

Does it really need preconditioning if you've just spend 2-3h driving, to get to less than 10%? I'd expect the battery to be warm already.

[@alainamyotte6127]

@@_pehash it does need to precondition if coming from highway driving. On InsideEV's podcasts Tom and Kyle have mentioned speeing up then hard regen to increase the battery temp about 10 miles before getting to a station if the vehicle has no preconditioning. If you have an OBD dongle then you can see if your battery is at optimal temperature before getting to the station.

[@dennislyon5412]

Tom - good stuff! If possible, would like for you to do a similar test at 40-45 degrees, trying to answer the question: where does the fast (over 200 kw) charging speed really show up? If your next test is at a summer 70 to 80 degrees, you’ll run into the high speed charge throttling that this car does as a warm battery heats up.

[@StateOfChargeWithTomMoloughney]

[@MihneaStoian]

[@wasabi521]

Can't wait until you run some tests at optimal temperatures. Perhaps a road trip to warmer weather is in order.

[@thelongdaysofwheeling124]

It would be interesting to see the pack temps on the overlays. I'm guessing the overlay at the 19 minute mark, even though charging started at either 0 or 10%, the pack temp was actually the same or very close. Then the natural heating effect of charging looks like it was contributory to it accepting a higher rate of charge at the same time... clearly, temps matter. Other who have done warm weather charging have been able to achieve 18 minutes with ease. Being in Canada, it's crucial for battery preconditioning on a road trip. Hopefully this is going to be updated.

[@timgurr1876]

Great video. I’d like to see the same test in Minnesota winter conditions, especially when temperatures are below zero F. Of course, for in town driving the time for charging isn’t that critical if one has a home charger. My concern is for those who drive 20 or 30 miles to work and then their car sits in the parking lot for 8 to 9 hours and the high temp for the day is -10 F (that’s the real world). Would be interesting to understand how those conditions impact battery temp. It will take time for business to install charging points and it would be very expensive to have a plug-in point for every employee.

[@StateOfChargeWithTomMoloughney]

Many EVs have a preconditioning feature that allows you to heat up the battery on the way to the fast charging station. That won't solve the slower winter charging entirely, but it will dramatically improve it.

It has never taken 18 minutes. Usually it is about 8-10, I love this car!

[@Alejandro-ut4up]

I have to add that if you have winter mode engaged it will turn on the battery heater while charging from a 240V EVSE or DC charger and that will eventually speed up your overall charge session, It could also potential explain your 2kW discrepancy between your 2 charge sessions.

[@danielroden9424]

Tom, there’s a bit of a scandal brewing over here in the UK, because for some crazy reason Hyundai UK only fitted battery heaters to certain cars if an option was selected, and that option was inlay available on the top trim level. So most UK Ioniq 5s have no battery heater, and will not even be able to benefit from an OTA update. They are physically missing the hardware. Many owners reporting really poor cold weather charging. I think it may also be the same situation in the US with RWD Ioniq 5s.

Tom, has the 350 kw charger been proven that it actually can put out 350 kw or is it a 350 amp - not 500 amp charger?

[@StateOfChargeWithTomMoloughney]

Hi David. That doesn't matter. It is a 500-amp station but it *could* be software limited to 350 amps. But as I said, it doesn't matter because the Ioniq 5 isn't capable of accepting more than 300-amps anyway. The charging stations weren't limiting the charge rate, the car was.

[@andrey_climb_bike_ski]

That 350 amp limit only really matters for 400V vehicles (but not necessarily all of them, depending on car limitations).

[@BassKlef1]

Seems the 350Kw station was malfunctioning? Strange…

[@laloajuria4678]

weird curve, weird thermal mgmt decision, and good to see 400V still produces useful long range charging infrastructure.

[@usa-ev]

Since both 150KW and 350KW chargers were the same there is some chance that the 150KW charger could also improve a little in the summer.

[@StateOfChargeWithTomMoloughney]

It's possible, but I wouldn't expect it to be drastically shorter, time wise

[@AriannaChelsea1]

Also, once the car goes higher than the 125kW charge rate, the battery is 25*C or warmer. That means you can unplug it and when you plug it back in, it will jump to the 230kW+ rate. IDK why the car doesn’t ramp to this and only caps at 140-150kW, but it’s bad programming on Hyundai’s part. I have an OBD reader and have tested this in many different cold-weather charging situations.

[@StateOfChargeWithTomMoloughney]

I agree. But I try to replicate what Ioniq 5 owners will experience. I don't expect people to unplug once they see 125 kW and initiate a new charging session.

[@AriannaChelsea1]

@@StateOfChargeWithTomMoloughney I completely understand. I just completed a Norfolk, VA to Reno, NV drive in my SEL AWD and it was nice to finally have an EV that kept up with Tesla charge/drive times (except the cold weather in the Rockies).

[@nxtiak]

Since it's summer you should redo this test. I'm in Southern California and never gets cold here so I've always gotten the advertised charge speed. But you should redo it so people are aware.

[@swhbpocl]

I doubt increased temperature will do a lot difference on maximal charging power. I do believe it will significant shorten or eliminate the initial 10-15 minutes of less than 100 kW power and shorten overall charging time that way.

[@StateOfChargeWithTomMoloughney]

It will. The Ioniq 5 will pull 235 kW (the most I saw was 147 kW)

[@berthogendoorn2133]

30 minutes is far better than my 2020 Kia Soul EV limited (64kwh), normally when around 30 deg. F. About 55 minutes 10-80%

[@be236]

Yup. Similar charging time in my Kia Niro EV 2019.

The inimitable Bjorn Nyland has suggested some ways to game the system, by strategically turning the HVAC on and off during DC fast charging sessions, and was able to get substantially faster charging. His strategy alternates between tying up, and freeing up, the HVAC system to focus on battery thermal management to force it to get the temperature into the sweet spot, and to keep it there. He used an OBD adaptor to monitor the temperature and identify both the minimum and maximum ends of the temperature range for maximum charging, and from there was able to design a strategy that keeps the temperature within that sweet spot. Hyundai/Kia can deploy software updates that does something similar to what he did, and I believe Bjorn suggested they confirmed to him they may do so. I believe they also suggested to him that they would implement a software update that turns on battery warming if you're navigating to a fast charger. Fully agreed that they shouldn't need KZbinrs to do this for them, though! :P This might be a factor of most of the design and testing of the E-GMP system being at South Korean temperatures, and as they gather more real world data from lots of different climates we can expect to see updates that improve things.

[@alejandrovieira6451]

I haven't read all of the comments, but have you verified whether the 350kW EVA chargers can actually produce 350kW, say with a Taycan or other 800V car? I think Kyle from Out of Spec has discovered that not all 350kW stations will actually provide enough amps, and then 150kW and 350kW become nearly equal in output. Sorry if you answered this question somewhere else!

[@StateOfChargeWithTomMoloughney]

Yes, I have. Both with multiple Taycans and the very next day with a BMW iX that pulled close to 200 kW. Kyle and I have been talking about the 350 amp limit for a while, but that wouldn't affect an Ioniq 5 because it can't accept even accept 350 amps

[@nycameleon]

I was just at a BJ's GAS the other day to fill up my wife's car, to save 20 cents we got in line... It took 25 minutes to get a full tank of gas.
