Hyundai Ioniq 5 DC Fast Charge Test

[@colorfulchew]

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.

I really wish you had added "Cold Weather" to your video description.

[@MrZola1234]

I really like how well you went over the charging with the charts. There are several folks doing these type of videos, but they never really get to the nitty gritty as you did in this video.

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.

[@carsonassociates3263]

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.

Cool video. Glad I line in the warmth. Yesterday at Burbank Electrify America on a 350, charging speed was 180 to 230 and went from 3% to 80% in 23 minutes.

Still impressive in cold weather. In my "old" Kia Niro EV 2019, on 50kW charger, in warm temps, to get from 35% to 75% in about an hour. To get me to about 93% is another 30 minutes.

Tom, awesome video 👍 I would like to see this test in the summer, our 2019 Audi eTron this winter many times 20* and less at times still complete charging from 6% to 80% in 28min .. 10-80% 26min .. the only thing we noticed when charging in the winter is the first 5-6min it does not just instantly to 150kW speed .. but yes at about the 5min mark it’s at 150kW all the way to 80% .. so I am still very impressed with this old 2019 Audi eTron ..

[@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.

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.

[@luketmarx]

As someone who would love to have an electric vehicle but can’t yet, it’s fun to learn about the technologies.

[@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.

[@itsbilln2178]

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.

[@rogerstarkey5390]

Here's what happens (roughly) 2 temps monitored. "Battery high" "Battery low". The low temp would be sitting at 10-15°c. (High temp, about 25-30°c) The charge throttles until the low temp hits 20°, first ramp. It holds until 25°, second ramp. It maintains that level until the "high" temp rises to about 40°. Slight dip, recovers. When "high" hits somewhere between 45°- 50°, rapid decline in charge. Numerous testers in Europe have confirmed this. . They need a redesign of either the cooling circuit, or the software controlling it. . Don't be surprised if you see an update "We've improved the ramp! (But you won't get the 240kW maximum any more) (Just my prediction)

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.

[@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.

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.

[@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.

[@evilbob2200]

since teh AWD versions have heat pumps they can precondition the battery (when the update comes) but i dont think the rwd has one.

Yesterday in NC. Mid 70s I went from 9% to 79% in 18 minutes. I had been driving nonstop on the highway for almost 5 hours. As soon as I plugged in, it was charging at 225 kWh. FWIW, I think the highway range yesterday was about 245 miles max (3.4 miles/kWh driving in Eco at about 72 to 78 mph).

[@lowrivera]

Most reviews that condition the battery, get the 10 -80 in 18 min. you can look up charging videos for the Ioniq 5 and almost unanimously, everyone has been able to do 10 - 80% in the advertised 18 minutes.

[@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.

[@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"?

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.

[@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]

It's confusing, if you have a video talking about this issue could you please let me know? Thank you.

[@larryallin7404]

The battery chemistry has a lot to due with the fast charging experience. I believe this model uses lithium ion chemistry which is known for its narrow optimal battery temperature operating range. this affects both the fast charging and operating experiences. Other newer chemistries have a much wider optimal battery temperature range and hence a better performance experience in both cold or hot climates. An addition benefit is less need for battery warming or cooling so possibly a longer driving range.

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.

[@ScrapKing73]

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.

[@edwardinedgewood]

Gas pumps are audited by the state (in Kentucky). Is anyone auditing electric chargers?

[@Trashed20659]

Haven't heard it was a problem. Gas pumps can be made to put less in the tank than the counter on the pump indicates, and your gas gauge is not very precise, so they have to check those. But a DC Fast charger will have a screen showing charge data more precisely, and your car should reflect that also, so anyone charging would know instantly if they were ripped off.

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.

[@CH-qt4hr]

this is a helpful video

[@NameNaameNameeNaamee]

The difference in dispensed energy is due to different losses. On the "right" session, the car had to heat the battery even more to reach decent speeds. Losses are massive at almost 18%, while time discrepancy towards advertised is as high as 66%! Hyundai really dropped the ball there, creating a battery chemistry that is ultra sensitive and will only perform well if within a very narrow temperature window, while having huge losses in pretty much every conditions, at the same time coupling it with a relatively inefficient drive train, which in summary pretty much eats up all the advantages the fast charging will bring you. Add to that the super weird preconditioning update that still isn't rolled out globally and will only work within a very narrow set of parameters, one of which is that it won't work UNDER 20 % SOC (you can't even just turn it on, you will have to have an active navigation towards a DC fast charger that is not too close, since it won't start preconditioning then to begin with...)...you can't deny that Hyundai fooled their customers pretty good with this car. It still is a nice one though.

[@IronmanV5]

As long as you can do 10% to 80% in half an hour is good enough. What would be much more important would be if they have canopies over the chargers and that they are located adjacent, or close to a decent coffee shop and/or cafe.

My concern is the situation with thermal runaway after a car sits in salt flood waters and owner moves car to garage and does realize thermal runaway has begun to battery bring exposed to corrosive salt water. This situation caused loss of car and home due to extreme temps. We need to talk about safety concerns from salt water rain and flood situations such as the hurricane Idalia in florida and incidents of thermal runaway. This existing problem needs to be talked about by more dealers, manufactures, and ev advocates

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.

It's a good thing to know the 18 minute figure is the best case number. But it's not misleading, that's what it's capable of doing in the right conditions.

[@rogerstarkey5390]

That's what it's capable of in *ABSOLUTELY* "right" conditions. But If it's TOO hot, the car will throttle both the top end charge *and* the drive power when you leave the charger (like accelerating up to speed on a highway? Just make sure there's not a Semi behind you!)

[@Lynyrd_Evnyrd]

My Model 3 always gets the “best case” because it preconditions before reaching the DC charger. Don’t give Hyundai excuses, they could do the same if they had on-route preconditioning like Tesla does.

[@Grahamaan27]

@@Lynyrd_Evnyrd agreed it's not as good because it's air cooled. Tesla's are some of the best

[@lowrivera]

Most reviewers that condition the battery, get the 10 - 80% in 18 min. I've looked up serveral charging videos for the Ioniq 5 and almost unanimously, everyone has been able to do 10 - 80% in the advertised 18 minutes.

[@LearningFast]

Do you have any links to those videos? I have seen the Alex on Autos video where he claims it did it but honestly I haven’t found many other ones that hit the 18 minute benchmark.

[@kevinn1158]

Isn't the heat pump supposed to warm the battery before a charging session?

[@francismarcoux8944]

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

[@laloajuria4678]

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

[@mrxman581]

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

[@Trashed20659]

in 2023 an update was issued to resolve this. The Ioniq 5 now supports pre-conditioning.

[@jamesdicken3442]

Tom whats the running theory on the large discrepancy on their 10-80% claim? I could give +/- 5-10% based on conditions. Is it not reaching its max potential charge curve?

[@StateOfChargeWithTomMoloughney]

Battery temperature. I'll repeat this in the summer and will most likely achieve the 10% to 80% in 18 minutes - or very close to that.

[@stephenholland5930]

The battery is "coldgating." If the minimum battery cell temperature is at least 25C/77F then it could take the maximum charge rate of around 230kW.

[@ianwoulfe4783]

I had about 250kW peek the one time I fast charged mine. 30% - 80% in about 14 minutes. I had driven it around town and it was probably 50ish degrees out.

[@StateOfChargeWithTomMoloughney]

I haven't seen more than 235 kW on an Ioniq 5, even in warm temps

[@turng]

@@StateOfChargeWithTomMoloughney wow you got 235 KW how many EV vehicle can claim that?

[@AeschylusShepherd]

Only the Ionic 5 limited has the warning. 18 minutes is from 20% to 80% charging. This is my understanding. If your car is charging below 20% you won’t get the 18 minute load time.

[@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.

[@1sword4you]

Is it warmer yet?
