Isn't it about time for Tesla to release an SAE Combo (CCS) adapter?

    There are quite a few DC charging stations appearing that have CCS plugs so it would be nice if Tesla would provide an adapter. In the past the argument was that there weren't any charging stations, but that is rapidly changing.

    Assuming that it only supported the most common DC mode through the bottom pins, it should be pretty simple since it uses the same kind of PLC signalling as Superchargers do. In the past Tesla has said it would be a passive plug, unlike the CHAdeMO adapter that has to do signalling translation.

    Are there many locations with SAE Combo plugs that do not also have CHAdeMO plug?

    At least here in CA, all the (non Supercharger) DC fast charging stations are either CHAdeMO only or ChandMO and SAE combo chargers.

    No, they are typically both, but a CCS adapter would be both smaller and cheaper than the CHAdeMO.

    Although I also want them to make one, I think it makes more sense in Europe at the moment (where CCS has exploded and there might be sites with CCS only). In the US, it is still moving very slowly and most CCS sites have CHAdeMO also.

    And from what we know so far, the superchargers don't use PLC signalling for the digital communication but rather a CAN bus (similar to CHAdeMO). The analog part however does match CCS protocol exactly.

    Tesla has limited bandwidth. I think that wouldn't be a high priority unless a large CCS network appears that serves routes not covered by superchargers or CHAdeMO.

    Ok, so $400 is too expensive? Really? We are talking about a $100K car after all...

    I'm pretty sure the answer is yes (price is actually $450 though), given there is a rental scheme for it. The CCS adapter can potentially be $95 like the regular J1772 adapter if it is a simple physical adapter (although no guarantee this will be true). $450 people still hesitate unless they are sure they will use it enough to justify, $100 would be a lot easier to justify regardless, esp. if things evolve where most chargers with have both types. No reason to spend $450 when $100 will accomplish exactly the same thing.

    Given that there are sill far more CHAdeMO chargers than SAE (and nearly the SAE's are also CHAdeMO), I would rather spend $450 on the CHAdeMO than $95 on an SAE.

    I bought the adapter to give me the widest set of charging choices. An SAE adapter would limit you to a small subset.

    I decided it was wiser to decline the twin charger option and wait for CHAdeMO adapter no matter its 2013 expected price was over $1000. Had to wait a year but price fell to $450. Have actually used it once! I'm happy as if I had good sense! Made a 250 mile day with 10 slow miles on the Barbers Motorsports track practical. I didn't have to limp to/from at 60 MPH.

    What a @#% mess with the DC fast charging cable situation. Sigh.

    I disagree. Tesla should only make a CCS or SAE Combo adapter when there are chargers actually installed that can do 200 amps or more. In the US, the only dedicated CCS chargers are the BMW i / ChargePoint Express 100 units that can only put out 60-ish amps DC which is about 24kW. That is nearly pointless for a Tesla. Audi is talking about installing fast chargers in the US for their upcoming long range crossover. These will presumably be 150kW SAE Combo chargers. Those would be useful to Tesla drivers and Tesla should make an adapter to allow it.
