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

I didn’t realize you were recommending a different adapter other than the Tesla tap mini! It sounds like this a safe option for L2 charging in your opinion @daveo4EV?

Tesla doesn’t sell the adapter that built into the universal wall connector, right? Wish they did

recommend is too strong of a word - I was simply pointing out the existence of affordable adapters…I have no personal experience with anything other than:
  • original 80 amp rated TeslaTap pig-tail - kept w/2020 Taycan but will be for my new Macan EV
  • TeslaTap mini - kept in my 2021 Cayenne TurboS eHybrid (used this week!! twice!!)
  • built-in Adapter included with Tesla Universal Wall Charger
there are lots of affordable choices in this space and unless a CCS1 adatper takes on the complexity/risk of an internal "switch/relay" for AC vs. DC charging - J-1772/CCS1 vehicles will need/benefit-from two separate adapters as part of their charging road warrior kit (the frunk is an ideal place to store these):
  1. NACS AC L1/L2 EVSE Charging cord -> J-1772 charging port on the Vehicle (TeslaTap or equivalent)
  2. NACS DCFast 400/800V Charging cord -> CCS1 charging port on the Vehicle (SuperTap or equivalent)
NOTE: even _IF_ a CCS1/NCAS adapter took on the complexity of the AC/DC internal switching/relay - it still would only fit one of the two charging ports on a Taycan/Macan/Audi eTron (SUV or GT) - so I don't think it's practical or desirable.

NOTE: to date I have not ever used a stand-alone NACS-Supercharger to CCS1 adapter as I've yet to own a CCS1 vehicle that is on the authorizied list of EV's for Supercharger access. I have used a MagicDock Supercharger in Scotts Valley, CA to charge my 2020 Taycan Turbo many many times…but I've yet to use a CCS1 adatper at a non-MagicDock supercharger…hopefully 2025 this will happen.

to my knowledge the adatper built-into the Tesla Universal Wall Charger is not for sale as a stand-alone adapter - you could call Tesla and ask nicely.

here is the official response from the SuperTap manufacturer:

No.... That would be way too dangerous.
The TeslaTap is for AC Level 1 and 2 Charging
The SuperTap is for DC Level 3 charging

Dave
this is as expected by myself and @whitex

J-1772/CCS1 vehicle's require two separate adapters for AC vs. DC charging - and that is likley to be true forever…

tho shalt not mix AC L1/L2 with DC 400/800V charging for God may look upon this as blasphemy and disgust and endeavor to strike ye's horseless demon silent carriage down with a terrible vengeance of lightening and fire (literally) if one's adapter is not flawless in God's eyes…ye have been warned!

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.
SuperTap vendor confirmed this is for DCFAst charging _ONLY_ and that it would be dangerous for an adapter to be both types - confirming the well informed speculation from this thread.

Using a "SuperTap" or some other adapter will make troubleshooting a problematic DC charging session even more difficult than it is today.
I remember reading something about Ford? reissuing Ford-provided adapters because earlier versions weren't working properly.
Who ensures 300-500 amp DC adapters are safe? Take it on faith?

The answer is either probably the manufacturer of the adapter, unless the seller indemnified because they designed it and/or designed the production process. Think whoever is providing warranty for it. No different than any other product. When you buy a Samsung TV at Costco, who is liable if the TV catches on fire and burns your house down?

I would argue it will be less problematic. Consider two scenarios:
  1. Ensure Taycan works with any of the DC stations designed, implemented (software), produced, and operated with various uptimes by dozens of companies.
  2. Ensure Taycan works with DC stations designed, implemented (software), produced, and operated with 99.99% uptime by a single company. The only variant is one of many passive adapters which interconnects CCS pins to NACS pins.
Which one is easier? IMO #2. There really isn't much to this adapter, same as the NACS to J1772 adapter. It's just direct pin-to-pin connectors, the only challenge is to make sure the connectors are robust and can handle the required current. Yes, there is a temperature sensor, but that is a passive part (most likely a $0.05 thermistor, same as what Tesla uses in their NACS handles).

Also, unlike the NACS-J1772, all DC adapters are supposed to be built for max current (no variants like 30A, 40A, 48A, 60A, 80A -> IMO this is purely marketing distinction, because the pins and the 1-2 inches of interconnect bar between them do not require that much more material or more expensive manufacturing - which is why my $30, 80A adapter I got doesn't overheat and has been working at 80A daily for me over a year and half now).

So bottom line, if you get your Taycan working with one Supercharger, it will more than likely work with all of them. If you get it working with ChargePoint DC station, no guarantees it will work with all of different EA variants, and Blink, and all others.

it doesn't matter - what choice do we have? it will either work or it won't - if doesn't work then you'll know you can't use superchargers…

this is the cost of the CCS1 standard be f'd up and having to switch

personally I love having the option - if it doesn't work that's no worse that most of my EA experiences…
