Hyundai IONIQ Electric Charges 50% Quicker From 175 kW Charger

APR 10 2018 BY MARK KANE 66

Fastned recently opened its first few 175 kW fast chargers in the Netherlands and performed an interesting comparative test on the Hyundai IONIQ Electric.

As it turns out, the IONIQ Electric can be charged 50% quicker (to 80%) from the higher power chargers than from an ordinary 50 kW unit. This is due to the fact that the car itself can accept 60-70 kW.

That makes charging much less time consuming.

“Charging the Hyundai Ioniq at our stations now ~50% faster because of new generation of 175 kW chargers. Quite a difference & this marks just the beginning of a global race towards MUCH faster charging… ⚡️”

I guess it might matter to me if there were any 175 kW chargers around. By the time there are enough 150+ kW chargers around to make a difference the lease on my Leaf will be up. My next car is going to be an AWD BEV SUV with a 300 mile range, that is rated for towing and has 150+ kW charging.

So you’ve decided to purchase a Tesla X 100D?!?Congratulations! (EPA rated 289 miles, up to 145kw charge speed, awd, 4,980lbs towing capacity, this is close enough right? All for a bargain price staying at $96k….

Not on your life. By the the time my lease is over there will be plenty of non-Tesla BEV SUV models available at half that price.

Tesla Model Y? 😛

No they wont.
Cause if Elon can ask for 96k others will too. Nobody is in it for charity.
Unless you want different size and trim.

I wonder if the Y will be rated to tow. And if so, how much. Because by the time the Y arrives, it should have options for everything you want, with the possible exception of the ability to tow anything of any noticeable size. Has Tesla said anything about the Y and towing? Or has there been a recent prediction with regards to when the Y will arrive?

Starting to think about waiting for the Y instead of getting a 3 SR, especially if the tax credit will be down to 50% by 2019. Might as well get the more roomy car and hope that Tesla will finally wake up regarding a normal dashboard, air vents, switchgear, window frames, ignition keys, door handles etc. Elon, think Equinox BEV, if you’re listening. The ONLY thing causing me to hold out for a non sci-fi Tesla is the Supercharger system.

I doubt it. I’m betting the redesigned S and X will look more similar to the 3. Even the Semi and new Roadster have 3-like zen to them.

There is already one major problem with the Model Y, it’s a Tesla.

It’s a problem that is worth waiting for!

My Leaf service representative today, just told me my 2016 Leaf SV needs its battery coolant replacement at its 24 month ( second annual service interval) and appointment in six months!

It just keeps getting better with Nissan intelligent mobility!

Fuggatboutit with those’s a lease

I’m glad you can see all the way to the to of your nose.

But: it wouldn’t make any difference whatsoever if there were infinitely many 150+ kW chargers near you long before your lease is up. The LEAF can hardly use the full power from a 50 kW station. (I have a 2012 SL imported from the US)

Appears that high percentages of rich EV owners (including Texas Leaf) are abusing their battery packs by constant over-charging (or seldom balancing their battery packs), charging too quickly, discharging too quickly(80mph travel & hard accelerations), & discharging often below 20% (even down to 5% & below). Original rich EV owners already sell EVs with abused batteries to poorer second & third owners, who don’t have the means to expensively replace abused battery packs.

Similar results have been reported before on these pages:

So you don’t need a 175KW charger for charge rates up to 70KW (duh..)


Actually the 175kw power rating doesn’t tell you much. It could be 175amps @ 1000v making it “175kw” but a car battery at 350v only gets 60kw @ 175amps. That’s why the current rating is what matters and their kw power rating is marketing mush.

It’s for 500V, I.e 350 A.

Scratch that, I might be wrong.

The real interesting thing about this graph is that the Ioniq charges at top speed until 80%. Non of this early tapering nonsense.

Not only does it taper later, but even after it tapers, it still maintains above 20kW until well over 90%. That’s why it can beat the Bolt on a long trips, despite the battery that’s half the size.

A comparative GM Bolt charging graph:

Not quite comparative. This graph is a Bolt on a 125A charger. It can go a little higher on the 175kW charger that this Ioniq was tested on.

I haven’t seen any tests with the Bolt on a 100 kW (200+ amp) quick charger. How many amps can it pull, and for how long?

There was someone in Norway who tested an Opel on a 200A charger. The car pulled about 150A, up to the same taper point shown above (about 55%). Basically that first part of the curve can be boosted up by about 20% (150/125)

Yup. It is a compliance car, nonexistent outside of California. It will never be sold in any significant numbers, so abuse that battery. The vast majority of Americans have never seen a fast charger. They may have seen one of those 240 volt trickle chargers at their favorite parking spot. 🙂

We are living in a country where the federal government explicitly denise’s the very reason for EVs.

You want to change the world? Change the choices that YOU make. My existence is almost petroleum free, how about yours?

Lets see:
Bolt electric car…check
two electric bicycles…check.
electric mower…check
electric weed whip…check
electric chainsaw…check
solar power from local electric coop…check
passive solar house…check
mostly vegetarian diet…check
vote for progressives…check

And it doesn’t do a bit of good…check

You spent all this money and look what it has netted you. On the whole more expensive alternatives that perform identically. You have been better off investing your money, not spending it on green tech/gadgets.

I did what my moral compass dictates.

My point was that the idea that we are going to deal with environmental collapse, by our individual purchasing choices, plays right into the laissez faire capitalist fantasy.

Does anybody think we got rid of smoking in public places, in the US, by choosing not to smoke personally?

Well yeah actually. Because so many people chose individually not to smoke, the number of non-smokers came to outweigh (greatly) the number of smokers. That made it possible to outlaw (in many places) public smoking. If 60% of the public still enjoyed cancer sticks we would still have to deal with their smoke.

As usual, California was in the forefront on banning public smoking. thedy banned it in 1995. Over twenty years after I quit. If the banning of ICE vehicles take as long, it will be far too late.

Now it’s a Friggin Vape Storm out there, you can’t legislate common sense!

Tom, that’s quite an ignorant statement.
My ev ($17k after all rebates and credits) is cheaper than the corresponding ice garbage ($19k) not considering fuel savings. In about 10 years it will pay for itself through gas savings alone. How much your ice will be losing?
My pv will pay itself out in 4 more years, after that at least 20 more years of free electricity.
Upgrades to make the house more efficient also pay for themselves overtime. Gray water system was on the plus side in less than a year. It’s funny you talk about investing but somehow you don’t see this as investing.

A Californian compliance car available in the UK?

It’s probably just production constrained at the moment so why not start with California.

The big problem is that people don’t buy (enough) EVs in the US and people aren’t aware and educated enough to make a better choice.
The only market worth mentioning is the Californian.

The Ioniq is sold across the globe at a rate of ~20k per year.


I’m actually surprised that the Ioniq only charges up to about 68kW. Was temperature an issue here? Because I thought it was closer to 100kW.

Judging by this, the Ioniq actually would not have a very strong advantage over a properly managed Bolt on a long trip. By that I mean keeping the Bolt below 50% charge so that it stays below its taper. The Bolt will be charging at 50-55kW and the Ioniq at 65-70kW. An edge for sure, but a small one. I’ll take the Bolt’s range over the extra 15kW charging speed any day!

Beat in mind that the Ioniq uses 30% less power than the Bolt, and you get an entirely different picture… I world choose an Ioniq before a bolt any day of the week… If the bolt were available for us poor froggies.

Bear, ont beat… french autocorrect is terrible for english comments.

Is that what transformed “denies” into “denise’s”?

Stupid autocorrect tricks! 😉

25% faster charging
30% less energy per mile
1.25 /.7 = 1.79
Or about 80% faster in miles added per minute. Point taken.

The Ioniq is better for sustained road trips, but it’s still a hard sell to a non-enthusiast.

The vast majority of my road trips are 300 miles or less. For those, the Ioniq couldn’t even make it today, since I wouldn’t make it the 140 miles to the nearest QC. If the network filled in, I’d need to stop at least twice, if not three times in an Ioniq. In a Bolt, a single stop over a meal gets me where I am going. So for me, the Bolt is far superior to the Ioniq.

Hopefully Hyundai will expand availability in the future for you, if that’s really what you want to be driving.

You must be joking!
It is sold in CA where chargers are all over the place. I’m sure you seen the videos of it charging 10%-80% in 15 minutes. Add to that the incredible efficiency at about 5.7m/kw, the better looks and the relatively low price for an ev and you get a winner. I would ratter have this than the Bolt all day, every day. This is perfect for CA, i hate Hyundai for dragging their feet with the slow release.

“Slow (as molasses) release”!

Not joking at all. It is also sold in NY. If I really wanted one, I could buy one and drive it upstate. Except that it would not make it the 140 miles from the DCQC in Albany to my home in Syracuse.

CA is not the world. Most places aren’t so lucky when it comes to infrastructure.

When Bolt first came out, I wanted one. But the Hyundai Ioniq has 5lug x 4.5inch wheel pattern. I have many used wheels & lots of tires that I got for our 2 Hyundai Elantras. I’ll save thousands of dollars, fitting wheels/tires for my future 60+ kW-hr Ioniq……when it comes out. Plus, I think the 60kW-hr Ioniq will still be a bit more efficient than Bolt & other 60kW-hr vehicles (most certainly better than Tesla 3).

Brian…..”I’d need to stop at least twice, if not three times in an Ioniq” …… In my Washington State, many chargers (even free ones) are in lovely areas worthy of stopping & sightseeing. Plus stopping often for charging in the mid-range of battery discharge is quicker charging per kW-hr, & easier on the battery pack.

What will be really interesting is what this is doing to the battery. Ioniq has active cooling but only air cooling. This isn’t Tesla quality thermal management.

Nissan had issues with battery degradation and now they are protecting the battery by never letting it go above 50C when charging (by limiting charge rate). How hot are the ioniq batteries getting after a couple 70kW charges, and can they take it?

It has been pointed out that the VW e-Golf also uses only passive cooling, like the Leaf, but without the reported widespread problems with premature aging in Leaf batteries.

Active cooling is still needed for multiple fast-charging sessions on long trips, but perhaps the need for an active cooling system for everyday driving has been exaggerated. It has recently been argued that the Leaf’s problem is more due to poor choice of battery chemistry than a lack of active cooling. Perhaps that’s correct.

If Hyundai uses battery chemistry similar to what’s in the e-Golf, rather than similar to what’s in the Leaf, then perhaps they can get away with no active cooling, so long as the speed of fast-charging is limited. However, based on what this article says, it appears Hyundai is not limiting the speed of fast-charging to what’s safe with only passive cooling.

Sure that’s the claim, but how many eGolfs are sold and how many years have they been around and how good is the data we have from owners? I really doubt the data is good enough to even know how the batteries are lasting.

So far the only good battery data we have is for Tesla and Leaf. One of them has a degradation problem, the other does not.

The Bolt also has high quality LG cells and a high quality liquid cooling system. And yet they restrict fast charging to way slower speeds than the ioniq. Are they protecting the battery? Or are they being unnecessarily conservative? Or is the chemistry totally different?

AFAIK, their air cooling system is active, not passive like that of the Leaf. As I understand, the battery gets cooled by cold air when the outside air is too hot and vice versa. Far less efficient than the liquid cooling solution of Teslas and the Bolt and probably has much worse heat distribution results due to the larger airways needed and the requirement for a compact battery. Worse heat distribution will probably result in increased cell degradation compared to liquid cooled systems because there will be cells that regularly get more heat than others. However, longevity will obviously still much better than a Leaf that has no heat conditioning at all. They probably oversize the air conditioning unit to cover both the cabin AND the battery and use intelligent /motorized airway splitting. So they can use any cells they like (within reason), only they need to ensure that the cooling/heating capacity of the air-conditioning unit covers the pack safely. Since, the cooling capacity of air is usually much worse than liquid cooling systems, they probably cannot go to bigger pack sizes with this solution since a bigger battery would produce much more heat. Possibly, this is the reason for… Read more »

A different take on the graph would be interesting too. Can we see a re-plot with time on the horizontal axis? How many minutes then to 80% on each? 20 minutes roughly on the faster charger?

Amusing, but only 70 kW with 28 kWh battery is only 2.5C. SparkEV is still the king of DCFC, 48 kW with 18.4 kWh is 2.6C.

Of course, compared to sloooow Teslas that taper only at about 25% state of charge and peak of 90 kW with 60 kWh (1.5C), Ioniq is decent. Don’t even mention the slowest DC charging EV in the world, Bolt.

You love spinning these numbers like this. And somehow I can’t resist responding. So around we go.

It is the most useless metric to the user to talk about C rates. The Spark EV has a very small battery, which has to provide a good deal of power to the motor (what is it, about 100kW?). That means it has a power-dense chemistry. This is compared to the very energy-dense chemistry of the Bolt. Well power goes both ways (in and out of the battery).

Spark puts out 100kW and takes in 48kW.
Bolt puts out 150kW and takes in 55kW.
Tell me again how much better the Spark EV is.

1. He really likes his car.
2. He really hates free charging.

Really….a lot.

C rates don’t make nearly the difference that miles of AER gained per minute of charging does. A high C rate and a small pack may please you, SparkEV, but most people want more miles per minute of charge time.
Many Tesla SuperChargers are able to charge the S at a rate of around 4 or 5 real world miles of additional range per minute of charging. That is probably the champion of electric cars that are out there in decent numbers.

^^ this.

Sparky’s incessant cherry-picking of figures to make the Spark EV look like it’s “best” at something — anything! — is not only misleading, it’s beating a dead horse. GM isn’t even making it anymore!

So Teslas are the fastest charging and can do it without degrading the battery. That’s a hell of an accomplishment that so far no one else has managed. Perhaps the Mission E will also do it.

Tesla has among the slowest charging. That is one of the main reasons for it not degrading that much or fast.

Charging is measured in C-rate.

Nope, not at all.

Tesla is right to move away from even talking about kW and kWh. The average EV driver cares only about range and miles added per minute, not kW or kWh. That’s a good marketing move, and will help Tesla cars appeal to the average driver. Joe Average has no idea what “C rate” means, and cares even less.

In the “early adopter” stage of a technology, there is a need for those early adopters to understand how the technology works, to get the best use out of it. But as a given tech progresses and becomes more usable by the average person, the need for such specialized knowledge disappears.

A lot of people will realise this very soon.

Mikael, that makes no sense at all. How many miles down the road will C-rate get you? It depends, right? But if you know the kW charge rate of a charger, you don’t need to know the C rate or the amperage, for the most part. Yeah there are exceptions when you get high and the car may be limited in the voltage or amperage it can accept, but the kW charge rate is the one figure that is relatively easy to use, though it is not perfect.
But if your car can charge at 75 kW and you are at a 50 kW charger, you have a pretty good idea that you can expect 10 kWh in every 12 minute segment of charging. Multiply that by the kWh you need for each mile of charge and you have a good idea of what your real world charge rate, and charging time needed, is.
And yes, I recognize that this is a disjointed comment on a relatively detail specific topic… 😉

In real life people don’t give a crap about C rate they care about how much range they can add per minute. And Tesla is by far the fastest there.

The closest competitor, the Bolt, is not even half as fast.

I really hope that the Jaguar I-Pace will do the 100kW up to 80% straight. It would only be slightly above 1C but it would leave a mark and get certain groups of people back on the footing of reality.

FastNed chargers are not at 175kW yet. They are current limited to 200Amps for the moment. Upgrade coming soon. Got it from the source.

This is cool, because this faster charging works for the Kia Soul EV as well. Ha, it looks I’m kind of future-ready…
