Hyundai IONIQ Electric compatible with 100 kW CCS

Hyundai IONIQ Electric

 

After the battery capacity disappointment, some good news.

 

When Hyundai revealed that the battery capacity was only 28 kWh for the electric version, it was a big disappointment. But now it’s time to analyze the pros in this car.

Hyundai IONIQ Electric is compatible with 100 kW CCS charging stations, but actually what does it means?

 

Combined Charging System (CCS) inlet

 

Most of current CHAdeMO and CCS charging stations are advertised as 50 kW capable, but 100 kW is already possible with these charging standards.

These are theoretical rates don’t happen in the real world, because they consider 500 V, when normally electric cars maximum charge voltage is set at 396 V.

Since electric cars never charge at the maximum voltage these charging stations can handle, the limitation is in the Amps. Most stations are limited to 125 Amps but 200 Amps is already possible with charging stations rated as 100 kW capable (500 V x 200 A).

Charging at 396 V and 125 Amps equals 49,5 kW. At 200 Amps equals 79,2 kW.

Hyundai says the IONIQ will fast charge from empty to 80 % in 24 minutes. This means that the IONIQ will never charge at 100 kW, it’s just marketing, like the fast charging capability in the Kia Soul EV. But at least it will reach the current limit of 125 Amps of most DC fast chargers that are available today.

IONIQ Electric also has an internal charger capable of 6,6 kW and complete the charge from empty to full in 4-5 hours.

 

Comparing to the electric leader, Nissan Leaf the IONIQ is:

  1. More efficient (lighter and more aerodynamic)
  2. Faster DC charging
  3. It looks better, at least for the majority
  4. The Hyundai warranty should be longer. Kia and Hyundai are known for offering longer warranties than the competition
  5. Better safety features

 

Price and availability are still unknown. The Kia Soul EV for example is very difficult to buy in some countries where it’s officially available. I think that the battery supplier (SK Innovation) is the most probable responsible, but with LG Chem making the battery for IONIQ, it shouldn’t be a problem.

Since the range it’s not the best in class, lower price could make the IONIQ more appealing.

If the upcoming Opel Ampera-e offers double the range but at double the price, I think that Hyundai IONIQ Electric has a reason to exist.

More than natural resources, are wasted human resources that bothers me the most. That’s why I’m a strong advocate of a society based on cooperation, not competition, that helps every individual to reach his full potential so that he can contribute back to society. “From each according to his ability, to each according to his needs”.

    If they follow Kia ‘s path will be nothing but a compliance car. The soul ev is expected to be available in Portugal for almost a year now.
    Can almost only be seen in Norway (if talking on European market).

    This car will be a great upgrade for my C-Zero:
    2x faster AC-Charging, 3x more DC-stations (I live in CCS-country), 2x longer range, 2x higher waf…

    Start thinking positive (and have nice WE).

    There is no way the Ioniq has better aerodynamic, than the Leaf.

    >>There is no way the Ioniq has better aerodynamic, than the Leaf.< Dimensions -> Aeordynamics

    Previous Leaf model years were associated with 0,29 or 0,32.

    And frontal area should be lower with the Ioniq too, due to its lower vehicle height. I think, width is about the same for both.

    Somehow, my posting got distorted.

    Leaf: cd is 0,28 for current model year
    Previous Leaf model years were associated with 0,29 or 0,32.

    Ioniq: Hyundia claims cd to be 0,24. See link above.

    And frontal area should be lower with the Ioniq too, due to its lower vehicle height. I think, width is about the same for both.

    Kia Soul EV has reported short-time *peak* charging rates of
    69.1 kW -> see arcticroads.com -> 120-kw ChaDeMo-charger
    69100 VA / 358V = 193A

    And from a charger in Germany at Kia head quarters for the Soul EV from a 100 kW ChaDeMo charger:
    “At low SOC (17%) I could see a charging voltage of 358,6V at a charging current of 175,6A = 62,97 kW.”
    So, 175A there. See goingelectric.de.

    So, the 125A are by far exceeded during the first charging phase, (constant current charging of the cell), where the battery voltage raises from about 3,5V to 4,1V or 4,15 or 4.2V per cell. Later, of course, amperage is reduced (during constant voltage charging phase of the cell). So there is no *average* of 175 or 200A, but these are peak values, but they are actually achievable in the constant current charging phase.

    Yes, 100 kW is still marketing, as a number of restrictions do apply, when actually charging a car.

    This is the more interesting matter of the Ioniq. They will probably first roll out the cars to the South Korean market, but it remains to be seen which other markets will follow at what point in time. Together with pricing this will have an influence on customer demand. The other important influence factor is actual production volume planned by Hyundai for the different markets.

    It’s nice to see, however, that the European model likely will have CCS, while the Asian model will probably be equipped with ChaDeMo. This is a change from previous Soul EV, which was sold with ChaDeMo on the European market.
