Tesla CCS Combo 1 Adapter User Manual (in English) Generates Questions

There has naturally been a lot of interest in a Tesla CCS adapter for North America (to replace and improve-upon the no-longer-available CHAdeMO adapter). (For example, see CCS Adapter Coming?)

As we know, such an adapter is supposed to be available in South Korea for ~$256 (US) (though it is "out of stock" at the moment). There is a Tesla pdf user manual, but in Korean (naturally) (CCS Adapter User Manual).

For those interested, here are the four pages translated (using Google) into English.

Page 1 --> Page 1 Page 2 --> Page 2 Page 3 --> Page 3 Page 4 --> Page 4
Cautions:
  • This effort was not sanctioned by Tesla.
  • There may be errors or omissions.
  • Do NOT use this information to import an adapter from South Korea or try to use such an adapter on a North American car.
  • Based on the description from the Tesla South Korea charging accessory website, this adapter is currently only for use with Korean Models 3 and Y at CCS charging stations in Korea.
  • If and when a CCS adapter is offered in North America, I am sure Tesla will immediately offer a region-correct user’s manual in English.
The contents of the user manual are straightforward. But it prompts questions aimed at those with first-hand knowledge of this CCS adapter, Korean Models 3 and Y, and South Korean CCS charging stations:
  1. What is the purpose of the apparently thin metal "pin" just above the Tesla Proprietary Connector plug (at the end that connects with the car? (See red arrows.)

    Pin (red arrow) - 1 Pin (red arrow) - 2
    It seems to align with the locking mechanism of the CCS charging cable connector (that attaches to the other side of the CCS adapter). Could the pin on the adapter also be for locking?

    Pin (red arrow) - 3 Pin (red arrow) - 4
  2. Is there a corresponding hole in the Tesla Model 3 and Y charge ports that will accept this pin? (I have a Model X; no small hole there.)

  3. Regardless of its intended purpose, wouldn't such a thin object be vulnerable to breakage during use and storage?
Last words: I hope that any similar North American adapter cost no more than, say, ~$150 or so (based on the plea of another TMC poster). It does appear much smaller and simpler than the ponderous CHAdeMO adapter, but it is apparently heavier than it appears in photos.

In summary, my primary concerns are:
  • Future applicability to Models S and X, in addition to Models 3 and Y, in North America. (I have an X.)
  • Vulnerability (to damage). (A foam-padded storage case from Tesla might be nice.)
  • Cost (though it should be well below the price of the ungainly CHAdeMO adapter).
  • The eventual fate of the elegant, simple, and slender Tesla Proprietary Connector (TPC) standard used by Tesla in Canada, the USA, Mexico, South Korea, and Japan (see Some of the Tesla Charging Accessories of Various Countries).
    • Will North America eventually just use the CCS adapter and continue with TPC ports and plugs?
    • Or will Tesla in North America (NA) inevitably adopt the CCS standard used by almost all other NA electric vehicles?
    • And will there ever be a worldwide standard? (Doubtful. With different electrical grids and competing financial and political interests, China, North America, and Europe will all resist change.)

Now that we have a rear view there might be an explanation for what that funny prong on the back is for. It looks like the charge port will push it into the adapter, probably to latch the CCS "trigger" latch in place when the adapter is plugged into the car.

Just found this post, which helps. But the "prong" still looks incredibly delicate to me (unless it's made out of some space-age alloy).

Hey, I've got a theory. When you insert the adapter in the car, it gets locked by the car's port just like any other Tesla handle (home charger, supercharger etc). I'm thinking that when you push that adapter against the car, that pin gets pushed back towards the CCS handle. Maybe it's as simple as that physical movement locks the CCS into the adapter. There would be no need for a hole in the car's charge port. As long as the car holds the adapter, that pin is pushed in and the CCS handle is locked to the adapter. When you remove the adapter from the car, that pin can come out and that releases the CCS handle.

Not sure, just a theory. If I'm right, there no big load on the pin, it's not there to hold the thing upright, so it doesn't need a space alloy.

The pin is a lock to prevent the CCS cable from being removed from the adapter when the adapter is in the car. It blocks the "trigger" operation.

Operation of this pin is at 5:35 in this video.

Excellent. Is there an English version or one with English subtitles? (I just looked quickly.)

I still think that users will have to be careful not to break the activation prong.

I tried ordering this already, then Tesla Korea cancelled my order and told me i can reorder Oct 26, looked on that date and no stock was available, I emailed them and got this reply:
Dear Mark,

I'm very sorry that you were not able to order this time.
We are trying to get extra stocks as soon as possible and expecting it will be in 1~2 weeks.

For now, you can get a notification from clicking the yellow highlight on tesla online shop when it's selling again.
Please make it sure to know when you are able to order again first.

Found it (Post #166 in the Thead you point to), thanks--it is a long transcription of the closed captions (in English) you can watch on the original YouTube video (spoken in Korean). Unfortunately, YouTube's instantaneously-generated English translations, while appreciated, are not particularly accurate. (I've experienced the same issue with YouTube's CCs for F1 Grand Prix videos narrated in German, French, and Spanish.) But, better than nothing.

Judging by all the interest in a North American CCS adapter, the moment that Tesla eventually releases one the Tesla Shop/Charging site will be inundated with orders. Likely to be sold out repeatedly on and off for weeks/months until the demand subsides. Hopefully Tesla will plan accordingly and have ample supplies stockpiled.

I wonder if a North American CCS adapter will also be just for the Models 3 and Y at first?

Writing as an interested reader and as the OP, no problem. The lessons I take away from this:
  • Do NOT buy a South Korean CCS adapter for use in North America. (We just have to be patient.)
  • Something (software or hardware?) in the Korean CCS adapter is incompatible with North American cars or N.A. CCS charge stations.
  • It is difficult to outsmart Tesla. ;)
  • There may be a CCS adapter for sale soon at a bargain price on the Seoul Craig's List site. :)

The adapter was briefly available for a few minutes then went out of stock, I missed that window between email notification and being sold out.
Have we confirmed this adapter does not work in North America?
Someone confirmed it with older firmware. The .40 version rolling out now is thought to have support for it, but it hasn't been tried afaik.

I have a 2020 Model 3 AWD and still it does not have the CCS chip, most Models on the road in north america are not going to be compatible without additional cost:...

For comparison I just looked at my AVI pop-up (from early 2021 Model X LR+):

AVI - 11-24-2021 - 2.jpg


Should I be concerned with anything?
  • No CCS adapter support.
  • No modem capabilities.
  • Small rear motor. (Guys hate to have a small anything,...except the prostate.)
