South Korea To Standardize U.S Version Of CCS/Combo Fast Charge Standard

JAN 24 2018 BY MARK KANE 29

South Korea, despite initial engagement in the CHAdeMO fast charging standard several years ago, is now making a switch to the CCS Combo standard used in North American – Combo 1.

It was already expected by the CharIn alliance, but become reality recently as the Korean Agency for Technology and Standards announced its decision to recommend CCS Combo 1.

Prior to the move, there was CHAdeMO, CCS Combo 1 and 3-phase AC European Type 2 standard) in use, both on cars and on the charging infrastructure side.

In 2017, roughly two-thirds of all new all-electric cars in South Korea were sold with the CCS Combo 1 inlet for 1-phase AC and DC fast charging.

It’s an open question as to whether Nissan/Mitsubishi will continue to be the only makers to sell cars with CHAdeMO, and whether or not Renault Samsung Motors will stick with 3-phase 22 kW charging instead of DC.

We expect that most of the other markets in the world that are not decided yet will go with the more universal CCS Combo 2 (the European version that offers additional 3-phase charging capability).

I Really don’t understand the choice for Type-1 combo as you can choose Type-2 combo and ship to pretty much the rest of world. Kind of odd.

The possiblity to 3 phase charge doesn’t prevent delivery of the car with the type-2 plug but just single phase charging.

Yeah, I guess this mean we wont get 3-phase AC on the Hyundai cars here in Europe. That’s a bummer then.

No. This is not saying that Hyundai and Kia will use Combo 1 in Europe, just in South Korea. For EVs in South Korea they’ll use Combo 1 and for EVs in Europe they’ll use Combo 2.

Yes, I also assume that’ll be the case, but the cars will still be fitted with the same lame single phase hardware behind the plug. Why would Koreans even bother developing three phase chargers if the home market and North America can’t use them?

Personally, as someone interested in a Hyundai or Kia EV at some point in the future, I think this is tragic step backwards. So much for 22 kW AC in the Niro…

Why would Korea go with an outdated system that only one other country uses, when most of the rest of the world is going with Type 2.
I still think Tesla’s plug is one of the best looking.

Australia is marked here as “not decided” – not correct, FCAI has settled on “CCS Combo 2”. Note this isn’t a government sanctioned standard. There are a couple of asterisks – the standard for new DC fast chargers is “Dual connectors – Chademo & CCS 2” to allow for the existing (small) fleet.

American car companies didn’t like the suggestion to make the Type-2 connector standardized world wide, simply because the type-1 connector is cheaper to make. Since they expect to make plenty, the extra unused pin was deemed uneconomic, seeing as very few North American cars make their way ‘across the pond’ and for those that do adapter cables could be made up.

Bigger reason – most of us in the US don’t have 3 phase power except on industrial connections. So, a 3 phase plug does not make sense.

Many U.S. public charging stations have 3-phase power available. It would have been nice if these charging stations could have offered faster 3-phase charging which could have reduced charging station congestion.

While that’s true, the car would have to have the additional cost of the 3-phase on-board charger in order to take advantage. Look at the VW e-Golf and e-Up. They have the CCS Type-2 inlet, but only have a 3.6kW single phase on-board charger. Sure, they can plug into an AC 22kW station, but they will still only charge at 3.6kW from AC.

I’m talking about the VW cars in Europe by the way. US cars have CCS Type-1 and either 3.6kW or 7.2kW single phase on-board chargers.

Look up Renault Zoe, with standard 22kW AC charging (connectable to 43kW), using the innovative integrated ‘Chameleon’ charger.

On the contrary if a 30 amp charge point docking station is a running off 208 volts or less then it is a tap off of a 3 phase connection.

I said what I did since some European said to me “why dont americans just use the type -2 so that it is standardized world wide”?

Answer: Car manufacturers here don’t want to use a more expensive Mennekes style jack since the Type 1 is cheaper for them to make. The opel Ampera-e is an example of a car with the Mennekes Jack but the car only has a single 32 ampere charger in it, same as the states.


You will get 3 phase, eventually

Basically the global EV sales is now dominated by Chinese GBT standard, which made the same decision choices as Chademo, but using differing plugs and protocol.

Chinese AC plug is a variant of Mennekes (different gender and some pin lengths)its currently single phase enabled, but is 3 phase capable (but not officially enabled yet)

so single phase for now.

Chinese DC plug is CAN based like Chademo, but different physically. Chinese DC is up to 750 Volt, so now the market can buy 750V Chamdeo stations now

The information provided by CHARIN is very misleading. Both CHAdeMO and GB/T are GLOBAL standards and their numbers far exceed that of CCS. It is up to the automakers to decide which standard to adopt, not governments or national organizations. Since when did AC charging become part of CCS ?

They are all so huge and ugly. Like a fireman’s hose.

If I had to pick, I can live with the China GB.

I want 200kW wireless charging 🙂

Are you sure? You have to have both the Type-2 style AC GB connector and the CHAdeMO style DC GB connector. Tesla’s European connector is much better, but they have relented and installed the double connector arrangement in the quarter panel of cars going to China.

I really don’t understand why Tesla didn’t place the GB/T plug into a matching panel on the other side of the vehicle. Tesla are such beautiful cars to be marred by this ugly fuel door.

By comparing the size of the single phase ac sockets, i can see that CharIn is subtly misrepresenting the size of Chademo DC.

Even china gbt is larger diameter (85mm) than Chademo (70mm) but not in that graphic.

The map at the top of this article is very misleading for a number of countries have chosen to offer mare than one standard type of EV connection plug.

By only listing one standard per country and orbiting Iceland, Australia and some other countries … the map come across more as propaganda that a reflection of reality.


Also leaves Newfoundland, Vancouver, and the Arctic islands out of Canada.

Everywhere that hasn’t decided should really just do Type 2. I wish that’s what we had ended up with in the US. It’s a better design.

Another nail in the coffin of chademo outside Japan.

Hopefully it dies soon in the US so charging companies can stop installing dual-head DC chargers that just muddy the charging waters.

Nissan really should have switched US Gen2 Leafs to CCS instead of carrying on with soon-to-be-dead chademo.

Strange it has New Zealand as decided, almost our entire vehicle fleet is second hand Japan, everyone will be using whatever they used 2 or 3 years ago, as they move and upgrade so will we. 🙂
You could try and push some other standard here, but the reality is the cars will be turning up with whatever was installed in Japan originally.
Also if you look at second hand EV’s currently available the LEAF far outpaces any other model to the point they are basically inconsequential to the equation.

There are many three phase outlets across Australia, which means non-CCS Combo2 folks can still benefit from 22kW recharging.
