Thanks for those graphs!

It looks by your graphs that the charge current drops when the SOC reaches about 72-76%. We pay by the minute when charging with Chademo as I guess You do too, so from an economic perspective, it seems like it is most cost effective to charge to between 72-76% right before the charging power starts to drop. Thanks for the info

info : in France, the new Kia 2017 don't have the cut at 84% ...
it charge from 0 to 94% in one shot.

That depends on the external charger as well as the car. In Korea the Ioniq Electric also charges on Chademo straight to 94%. But in my usage the charger stopped at 84% at four of the 8 different chargers I tested.

We pay by the kWh so it doesn't make any money difference to plug in again and carry on to 94%.

Other graphic from a Chademo charger with telemetric log in the customer account.
It's the Kia Soul EV 2017 (45 to 94% in 1 shot).

In France : Charge cost in 15min timing (no kWh) = 3,5 Euros.

If you look closely, you see the moment when the car switch from 390v to 394v for the constant voltage demand.

JejuSoul · Oct 15, 2016

The Kia Soul EV can charge at rates greater than 50kW if you can find such a c harger.

At KIA Europe's headquarters in Frankfurt there are two SIGNET 100 kW c hargers based behind closed doors - only for registered Soul EV users.
Despite being for Kia Soul EV only these two c hargers are dual head Chademo and CCS --- see Kia Installs First 100 kW CHAdeMO DC Fast Chargers In Europe
Here in Korea every Kia and Hyundai garage I have been to has had Chademo only fast c hargers.

Here's an image of a Soul EV pulling 63kW --- see http://www.goingelectric.de/forum/kia-soul-ev/ovms-fuer-den-soul-t9741-110.html#p277579

There also now seems to be a series of public c hargers in Norway that can charge at the higher rates. --- see https://www.minioniq.no/faq

I ONIQ will get fastest in its class rapid charging of up to 70 kW charging capacity. A nationwide network of fast c hargers that 70 kW + is under development and we make it possible to run I ONIQ from Oslo to Trondheim simply by charging less than 1 hour in total (3x19 min). Super Quick C harger for I ONIQ already exists in Vestby, Storebaug west (Moss), Svinesundparken (Halden), Grelland West (Vestfold), Lillehammer, Aurland, Lom, Dovre, Bjorli, Hjerkinn, Oppdalsporten (Fagerhaug) On other fast-charging stations, the capacity is limited to the c harger capacity (normally 50 kW)

A question for the Norway users. Are these new 70kW c hargers Chademo as well as CCS?

Birkeland · Oct 16, 2016

I know the chargers from a company called Arctic Roads in Norway (currently 12 chargers, will have 388 chargers in hopefully near future) have both CHAdeMO and CSS. The chargers offers 120kW, but if a car charges with more than 50kW, it is not possible for another EV to charge at the same time. But both CHAdeMO and CSS can be used as long as the charge current is less than 50kW. Other than that, there is mostly 50kW CHAdeMO chargers.

JejuSoul · Oct 16, 2016

Thanks Birkeland.
The 12 c hargers mentioned by Hyundai are the same 12 Arctic Roads c hargers you talk about. You can see them all on the Arctic Roads website.
I was hoping that Hyundai would be providing the infrastructure much as T esla does with their SuperC harger network but it seems not.
see - Arctic Roads Opens 120 kW EV charger to the public - it is in English. Click Ladesteder on the top to get a Google Map with the location of these c hargers.
Having 400 of these stations in Norway in the near future would be really amazing. Currently Korea has nothing greater than 50kW.

The Kia Soul EV can charge at these c hargers. We have commented before that they can draw up to 70kW from these.

Here is a photo I took at a Hyundai c harger at at Hyundai service centre here in Korea.
There is a slow charging charging L2 connector on the left and a Chademo on the right.

SoulEV2016 · Oct 16, 2016

One thing that's usefull when you have torque pro with obd2 reader ... is this : you can see the restriction at the car (from temperature or profil of the driving).

Chademo is restricted by that, too ...
when you drive fast, the restriction don't evolve quickly.

Perhaps, in the futur, i can travel to a 100kW Chademo and view this restriction in action.
For now, i only have 43kW Chademo charge station.

90km/h at 6°C, short trip.

154km/h at 13°C, long trip.

Switzerland has some faster charging stations too. Tom from the German forum reported he used one today. http://www.goingelectric.de/forum/kia-soul-ev/kia-soul-ev-2017-t18746-10.html#p409529

This one is a 60kW c harger in Bern --- http://postparc.ch/tanken-sie-strom-im-postparc

This one is 150kW at the Gotthard pass --- http://www.gofastcharge.com/de/

Here's some more info taken from the 100kW Chademo station at Kia's Frankfurt Headquarters.

@Jejusoul

How do you pay for charge in Korea ?

In france, we must have a collection of RFID card (it's hell) ... and a monthly subscription.
And then, the cost add is in 15 minutes segment.

example :

- no subscription = buy a card with 20 USD ... and you can use for 2 separates charges only (no time restriction).
- monthly subscription for 3 USD and then, the 15min of charge cost 3,5 USD.
- monthly subscription for 10 USD, 15min of charge = 1,5 USD

JejuSoul · Oct 20, 2016

In Korea public chargers cost about 30 cents American for one kWh.
This is the same as the daytime peak rate we pay at home.
But the night time off-peak cost is only 6 cents.

I have 3 cards for 3 different networks. No subscriptions. Just pay at the end of the month for what you use.

Example: Happy-e-Charge card at L3 Chademo station at shopping mall carpark on the mainland. I never saw other people using these. Never had to wait. In driving the whole of mainland South Korea I only saw 2 other EVs.

On Jeju island there are hundreds of free public L2 chargers. The nearest Chademo at the Kia garage is also free. I have never paid to charge here.
On the mainland however chargers are scarce, and most are paid. On my trip around Korea in an Ioniq EV I paid 80% of the time. It cost about 50USD to drive 1750km

Example: 4 free workplace L2 Chargers on Jeju Island. In the picture 4 Soul EVs, one Spark EV and one Blueon EV. These chargers are normally busy, you often have to unplug someone who has finished.

SoulEV2016 · Oct 20, 2016

Perfect, thanks for that.

JejuSoul · Oct 25, 2016

There is a research paper on the AVT site that shows graphs for charging four different Soul EVs at 0°C, 25°C and 50°C

PDF report here - DC Fast Charging at Different Temperatures

The cars are tested inside a container with controlled temperatures.

Four different Soul EVs using Chademo at 50°C

I am particularly interested in Note 5 at the bottom.

The thermal regulation load is an approximate calculation of the amount of energy used by the vehicle to regulate ESS temperature, where applicable. This is calculated by subtracting the amount of energy into the ESS from the amount of energy output by the DCFC; the calculated value also includes resistive and conversion electrical losses.

In the case of the Kia Soul EV, thermal regulation was engaged during the 50ºC test. However, it is possible that the energy values noted for the 0ºC and 25ºC tests are due to parasitic losses or powering of the vehicle fast charging system. There are three possibilities for how the onboard vehicle electronics receive power during a fast charge
1) 12 V interface on the CHAdeMO c harger,
2) DC-to-DC converter steps high voltage down to 12 V,
3) the system could be powered directly from the 12 V battery of the vehicle.

It might be interesting to compare the energy required to cool the pack at 50ºC from various different EVs. !!

Especially when I see this in the report for the BMW i 3
"During testing, fast charging at 50 °C DC was not able to be conducted due to the vehicle preventing the charge event from occurring."

Annoyingly for the 2013 L eaf
"The enclosure temperatures were not measured during the initial testing of the 2013 Nissan L eaf, but they will be recorded in future testing."
.

SoulEV2016 · Oct 25, 2016

Other point (or question) : this car at 50°C of ambiant temperature ... but the inside is cooled by the A/C ?

Because of this, the fan of battery use cold temperature (and expulse this at the event on the rear bumper).

or the car is OFF during the charge ?

it's a good question because i regulary charge my car with me inside (because it's fast), so i use A/C in AUTO mode when i charge.

in my country, you have 28-35°C ... or +5°C to -20°C (it's not country for bike, it's sure).

and this case can modify the fan strategy.

An interesting pdf by the AVT here - DC Fast Charging Infrastructure 50 kW to 350 kW

JejuSoul · Nov 26, 2016

Here in Jeju we have electric buses. Mostly they use a battery swap system, but they can also use Chademo. The battery in the bus is rated 102kWh and 600V.

I went to test one of these bus L3 chargers today. The sign underneath warns car drivers not to try it because it uses a higher power than normal. I tried anyway but couldn't get it to start because my cards didn't work. Anyone know if the Chademo protocol has a higher power rating for buses, and if so what happens when you plug a car in.
