Hyundai IONIQ Electric Accepts Up To 70 kW From 100 kW CCS Charger – Video

JAN 23 2017 BY MARK KANE 43

Bjørn Nyland after just filing a detailed test drive review of the new Hyundai IONIQ Electric, has shared video of the EV’s fast charging abilities.

As it turns out, when connected to a 100 kW CCS Combo charger, the IONIQ Electric accepts up to 60-70 kW of power.

A charging session starting from about 10% of capacity, filling up to 94% (fast charging above 94% is not available), took about 30 minutes. Bjørn notes for the last 15%, charging maxed out at about 20+ kW.

The Hyundai’s on-board reporting system indicated 25.5 kWh was charged (the battery is 28 kWh usable overall).

“Hyundai Ioniq supports up to 70 kW via the CCS plug. I tested this on a 100 kW Delta charger at Vestby, Norway last night. Peak power was 69.3 which was pretty close. The Ioniq has a 28 kWh battery pack. That number is for available energy. I believe the car has the same battery as Kia Soul EV which is a 30.5 kWh.”

Ok, someone give Bjorn a Bolt (or Ampera-e) so he can test it on the same charger.

By calculation, I think the Bolt can only do roughly 50KW on DCFC. Then a taper down.

The calculations show approximately a 50kW average over the first 30 minutes. We don’t know if that means it’s flat 50kW for 30 mins or starts higher and then goes lower.

There is a graph from a Bolt EV on a 50kW charger. But of course that’s likely charger limited. It’d be great to have a graph from a higher power charger to get more info.

50 kW would mean less than 1C charging. The Ioniq is charging at ~2,2-2,3C

If the Bolt could do the same then we are talking ~150 kW.
Even at Teslas low ~1,2C charging the Bolt should be able to take ~80 kW.

It will be interesting to see someone doing a proper Bjorn test on the Bolt.

So far the highest capacity CCS I’ve seen a Bolt EV on is a 125A unit. And the Bolt EV takes all of that up past 50% SOC. It would be interesting to see what a Bolt EV can do with a 175A or 200A unit.

The Bolt EV will charge at 125 amps to about 65%, where the amps reduce.

Assuming a 300 volt depleted battery at 0%, and increasing to 365 volts at 65%, then the maximum charge rate is:

37.5kW = 125A * 300V @ 0%
45.6kW = 125A * 365V @ 65%

The charge amps / chargerate reduces from 65% until fully charged.

The average charge rate from 20% to 70% is about 42kW. For long-distance travel, it would not be wise to charge up while enroute above 70 to 80% to optimize time. The same is true in a Tesla car.

Depending on many many variables, the car will add 60 to 90 miles of additional range within 30 minutes. Most people will find about 75 miles added to be their average.

When does yours come in???

His Bolt has already come in but I assume that in his area, the public charging options are between 24-50kW. That’s how it is in my area anyways.

So testing it wouldn’t provide any information as far as 80kW charging goes. The first faster chargers should start trickling out from evGo and Chargepoint this year though so we will know soon. 🙂

“His Bolt has already come in but I assume that in his area, the public charging options are between 24-50kW. That’s how it is in my area anyways.”

That makes sense. I asked him to find a charger more like 80kw weeks ago.

Maybe he has kids and a job and hasn’t had time:)

80kW CCS seems to be a unicorn around my parts.

You have the coldest weather Bolt for a few weeks. Can you leave it out overnight unplugged sometimes and see how much range it loses? It will supposedly take energy from the battery to heat the battery at night if it is cold enough. GM would seem to imply this starts below 40F or 32F or something.

But GM doesn’t say how much you’ll lose. It would be great to start getting some estimates.

Also, be sure to check the air in the tires. If they were filled at the dealer at all it was at a place 30 degrees warmer than where you are. They will probably need some air.

That very thing happened in this video. The Bolt EV sat two days in subzero temps and resulted in negligible battery loss.

Which video? The video I see above only has a Hyundai in it.

Oops, I forgot to tag it:

I’ve had to only plug it in every 3 days or so. Temps haven’t been very cold in MD though (low 40’s, mid 50s), so can’t really comment on cold weather soaking. But the GOM estimate hasn’t ever changed from when it was parked for the night and the next day.

Just published my latest blog entry, btw.

iPhones don’t have the black bar problem on the map display. It certainly is an Android Auto thing.

For me the armrest has two positions. Too far forward and way too far forward.

If you click on his name (bro1999), it opens to his blog.

Wow, That’s 2C+ charging rate. At 80% mark, no less! If Volt did that at 150kw charger, it would take only 20 min to charge enough to drive 150 mi. Or 15 min for Tesla S60. That would be the holy grail for the charging time.

SparkEV charges 48 kW up to 80% using 18.4 kWh battery. That’s 2.6C. SparkEV is the quickest charging EV in the world in terms of C rate, and that’s with “ancient” battery technology.

Thats a good point. I’ll bet the Bolt will charge up to 80 kw.

The Spark has A123 cells right?

They are renowned for their durability and high power applications.

I understand the downside is that they are very expensive compared to LG Chem, etc.

2014 has 20.5 kWh of A123. 2015 and 2016 have 18.4 kWh of LG Chem. I have 2015 with LG cells, and it charges quicker C rating than 2014’s A123.

From, it seems Bolt doesn’t charge as quick as SparkEV. Bolt tapers starting at 50% and pretty bad at 70% (only 25 kW). I don’t know what may be the problem.

That data is from a 50kW charger. GM says the car does best on an 80kW charger. With the lower voltage of the Bolt pack the car needs more current to charge at the same kW rate.

The charger may have run out of current and reduced the charge rate.

It’ll be good to see some curves from a higher powered charger. There’s some hope yet.

They are also LiFePo4 chemistry. Those cells were the shiz!
Not sure if they have those specs after being bought by that Chinese company.

This is still limited by the charger. It appears to be running at constant current, which I’m guessing is 200 amps, all the way to 80%. It maxed at about 69kW, which at 200 amps would indicate 345 VDC pack voltage at that SOC. That totally adds up. I wonder what the actual current limit is on the car.

It will be interesting to see what these cars will do on the ChargePoint Express Plus chargers when they’re available.

No, it doesn’t totally add up if you divide by 96 cells in series. How do you know it is the charger and not the car limiting Amps? Hyundai specifically says 70 kW max charge rate.

Did anyone ever try this on the Kia Soul EV? I thought it was rated to 100. Really hoping that KIA/Hyundai both kick it up to 200 mile batteries soon. They could really earn a place in the standings if they actually pushed it out there.

Yes, it looks very similar. It is the same parent company after all.

Although the Kia and Hyundai batteries sound similar, I believe that is just a coincidence since Kia uses cells from SK innovation and the Hyundai Inoniq uses LG chem cells similar to what’s in the Chevy bolt.

Pictures of the battery packs show the Ioniq’s battery to occupy a much lower volume compared to the Kia Soul.

The Kia Soul EV uses CHAdeMO

I’m very, very glad to see these reports of faster real-world charging rates in newer EVs… not to mention the older Spark EV!

This is the sort of progress we need to see, to get EVs which are more competitive with gasmobiles.

The EV revolution is advancing!
🙂 🙂 🙂



In ten years we will laugh at all the discussions we had about charge time.

By then 500A @ 1KV will be the standard… As 100kwh batteries will be… Good times ahead!

Still waiting for VW, BMW, Mercy and Toyota to start doing anything serious. Up to now it is just laughable.

2C is good if they are using super high energy density cells, if not then not all that impressive.

Anybody have an actual date when the Ionic BEV will be released in the US? Supposedly winter but isn’t it mostly over??

Winter is about 1/3 over. It ends when Spring begins March 21st. It’s good that it works that way, that way we are always in season.

No date, but Hyundai-Kia doesn’t work like that. H/K’s media/PR around plug-ins is about as stealthy as possible (or it may not actually exist at all, lol). They just suddenly appear.

As a case in point, the Kia Optima PHEV arrived in the US ~January 16th with the fanfare of….nada.

If you live in Pennsylvania, they’re probably a year away.

Hyundai, just put another 10-15 kWh in the Ioniq and you will own the entire EV market!

Or not.

Not if Ioniq is priced similar to Bolt since Bolt performs lot better and has better rear seat/room. What will make it a good seller is pricing. Even with current battery capacity, make it under $22K after subsidy, and it will sell well. I doubt that’ll happen.

I did 430km of highway driving yesterday with Ioniq, driving from Kuopio to Helsinki (Finland). Spent total of 45 minutes charging and this is Finnish winter. This car can get me around almost as fast as a gas car. Range per charge in the sleet, on wet roads was around 200km. I bet I can break 300km during the summer. The car is VERY WARM and speed does not make that much of a difference to the consumption.

The funny thing is, Ioniq seems to do the same thing as the Leaf would do with a 48kWh battery. I had a Leaf before and this just doubled the range and quadrupled the usability due to the blazing fast charging.
