Nice, if you guy are following all of the nacs to ccs adapters recalls it's pretty crazy out there...

 

[daveo4EV]

yeah - but still requires vehicle vendors to be "on the list" of allowed vendors to start a charging sessions - VW/Audi/Porsche are "not on the list" so far…plans call for 2025 - we'll see if/when that happens - this adapter should work for other approved vendors (Ford, GM, Rivian, Polestar) but other EV's are waiting their turn to work with Tesla to be added to "the list"…

so we wait!

I guess until Porsche/Audi/VW get a deal with Tesla there are no adapters for me to buy so I can use a Tesla supercharger but could I use one of these adapters at a free L2 charger at hotels?

There is a product for that, but this likely isn’t going to work for L2. If you look on the website, they have just a basic Tesla Tap (no super) that will work on any J-1772 car to use a Tesla L2 destination or home AC charger.

Oh you think this won’t do L2 charging? Was hoping I could just buy one to do both when we start being able to use the superchargers.

it may work for L1/L2 charging but only one of the two plugs - you won't be able to plug it into the driver's side of the Taycan - and I don't know if the car would be confused doing L1/L2 AC charging when there is adapter that has pin's occupying the FastDC charging pin's on the charging port

physically the adapter you show requires a full CCS1 plug/charging-port - there is only one of those on the Taycan (passenger side) - the adapter will not physically "fit" on the Driver's side charging port…

if you want to be able to use either side of the vehicle to charge from L1/L2 AC chargers you'll need sa 2nd adapter…

A new NACS to CCS1 has now been announced (and currently in stock, $250 price), SuperTap by TeslaTap

while not definitive - the statement on the website says:

"Our TeslaTap SuperTap adapter gives any North American Electric Vehicle the ability to charge on the Tesla Supercharger Network*"

that could be interpreted to to be "only" Supercharger network - which would rule out AC L1/L2 charging with a NACS L1/L2 AC EVSE…

 

[daveo4EV]

I sent customer support the question if the adatper supports both L1/L2 AC charging and FastDC charging

this could be complex - some vehicles may "sense" the CCS1 fastDC pins being "connected" and get confused/fault if they then encounter a L1/L2 AC J-1772 charging session - i.e. it's probably not a well tested scenario and this adatper may work for some vehicles and not for others

I can 99.9% guarantee if it does work it's an accident not a design goal and I would be surprised if _ANY_ vehicle vender tested it…

 

[daveo4EV]

CCS1/J-1772 vehicle such and Taycan/Macan/Audi will be best served by carrying two NACS adapters

one adapter for for NACS AC L1/L2 charging
another adapter (such as this one) for NACS based FastDC CCS charging

reference post #2 from this thread…

• J-1772/CCS1 "native" vehicle
  

  • Adapter J-1772 Vehicle to NACS slow charger
    - TeslaTap or equivalent - $100-$300 depending on cable "rating" for up to 100/80 amp 19.2 kW charging
    • Taycan/Macan owners only need 60 amp version (Taycan optionally 100 amp version if you option the 19.2 kW option - no 19.2 kW option for Macan EV's so far)
  • Adapter CCS Vehicle to NACS fast charger - $199 - Ford owners can use these today, other CCS1 vehicles in the future - however requires your vehicle be "authorized" by Tesla for network access - today only Ford vehicle's are allowed to start a charging session

I'd wager that the AC pins are not even connected on the CCS1 side. There is no need for them to be connected, and, more importantly, I am certain that shorting together AC pins with DC pins on the CCS side (since they are the same, dual function pins in the NACS connector) would cause both; issues in operation, as well as safety issues (e.g. Taycan has 2 ports, if you connected such DC adapter which would result with 800V DC across the AC pins, that voltage would also show up on the AC only port, which is not designed for it - functionally and safety wise).

I agree 100% - they would need "active" multiplexing inside the adapter - and they would need to route DC power to the DC pins, and AC power to the J-1772 AC pins - it's feasible, it's technically possible - it's highly unlikely and un-necessary work/complexity for this adatper if it handle's both FastDC and AC/L1/L2 charging…

Last I heard, all of these are supposed to be passive adapters.

EDIT: Furthermore, active multiplexing of many hundreds of Amperes on DC would require relatively expensive components (and probably be larger in size).

 

[daveo4EV]

I agree but it appears they are "active" to some degree - at least this one is…

see description …

• Adapter has both CCS and Tesla Safety circuits
• Cannot be removed during charging to prevent arc flash
• Overheat sensors (2) to slow/stop charging above 185°

admittedly the above feature set could be done "passively" with some bare minimum design that would "pass" for Passive - but the safety circuits, the lockout, overheat circuits 'slowing' the charge rate requires some interaction with the CCS protocol - or at least current flow detection - the "slow" charing feature seems to be the adapter can "push back" on the CCS protocol to "inform" the charing stall to slow the current flow rate - at least I would presume - I'm a CS major not an EE

but there a bit "active" in this unit - but I agree the effort to do multiplexing of DC vs. AC onto the correct output pins is "more active" than the features listed above - although it could be a simple relay - the "knowledge" about AC vs. DC is "known" from the first plug-in as the type of EVSE is identified from the two low voltage "comm" pins - so once you know - you know - flip the relay - and you're done - if it's wrong - unplug it - replug it in and try again…

I still agree there is only about a 1% chance this adapter supports both AC and DC EVSE's due to the complexity of needing to multiplex the power inputs onto the right output pins - and the increased complexity - the juice simply is not worth the squeeze when the pure AC adapter is less than $50

also having the adapter NOT work for AC - means it will _NEVER_ accidentally route 800V of DC power into the AC pins of the vehicle - cause unknown damage - to the vehicle and charging stall…

it's simply safer for all parties involved to have that scenario be impossible.

$37.99 for the AC adapter…

so $249 for the NACS-CCS1 vehicle adapter
$37.99 for the NACS-J-1772 vehicle adatper

and you're out with two adapter for less than $300 + tax + shipping

Temperature sensing (probably a couple of thermistors - similar to what Tesla uses in their handles) are not really active components. I fitted such sensors into J1772 handles when retrofitting my Tesla HPWC's to J1772, to keep this safety function.

Anything that can connect/disconnect 615A (V4 supercharger max current) would be a really heavy duty relay, which would not be cheap ($80 min) plus it would require its own source of power and a circuit to control it. Doable? Yes. At $249 retail price (so $83 manufacturer landed cost max), very unlikely. Something Elon/Tesla would suggest? Not a chance. KISS is a guiding principle there, and such active adapter would just be asking for problems, both functional and safety related.
