Received A2Z EV (NACS to CCS) adapter today

He does get carried away. . But he is really intelligent and knowledgeable about his subject matter.

I like the longer videos, it's refreshing to not have meme's and stupid sounds every 15s in a rushed 5min video where every other phrase is clearly edited together because they can't just spit it out in one take.

Your point was that the adapter can’t distinguish the car’s make/model and that Ford and GM have been designated as first. That would be a good reason why you could not use this adapter. I checked my receipt from the Tesla Magic Dock session and it did not list my VIN (bad sign), but charging a Tesla does list my VIN. EA can identify my car though, is it really that Tesla can’t or is it that they just aren’t yet because the Magic Dock is the gatekeeper so they don’t need to. I don’t see why Tesla can’t do a VIN lookup before initiating to determine Ford/GM. I think they already do that for salvage Teslas to block them from supercharging.

I think we are actually in complete agreement. I was responding to a post about not using plug and charge and only using the Tesla app to start a session. I expect any adapter that has the pins connected correctly is going to work (at least for a while) even though Ford and Tesla may warn you to only use certain ones. I think they will have to use the vehicle to charger communication to limit who has access. It will be interesting to see if they leave the Magic Docks open to everyone once they open up to adapter use. I think they will because they are using them to gather data on other brands so they are ready when they do open up.

There is NO UPDATE NEEDED.

Louder for those in the back of the bus please.

what are you talking about. NACS isn’t magic dock. How do you figure? It’s all software.

and if no update is needed, why would automakers need to “sign on” to use NACS. It’s not only the physical port switching from CCS to Tesla. Did you know NACS isn’t even how Tesla superchargers communicate with Tesla cars.

Discussed over and over again...

Ford and Telsa are working to get Plug and Charge / FordPass to work, that's the way we will charge. Plug in vehicle, vehicle and charger communicate. No software needed (which is how Tesla can prevent Ford from working today). Tesla transmits to Ford, Ford checks and says "Bob has a credit card on file, go ahead", and Tesla starts charging.

Nothing needed in the vehicle at all, except updating the map to include Tesla chargers, which comes from the server and not via an update.

GM doesn’t use plug and charge. NACS is a standard. I don’t know where you are getting this info from. CCS right now has communication protocols for the vehicle and charger to talk. The vehicle and charger must talk.

They'll definitely leave Magic Dock open to all CCS vehicles - it's part of qualifying for government funding. They committed to having a certain number of Tesla Superchargers open for public charging.

Communication with the vehicle will verify the vehicle - likely through its VIN. This will then be checked against an existing database of eligible vehicles to charge, likely very similarly to how Tesla verifies its own vehicles by VIN.

There wouldn't need to be an OTA update to the vehicle. Ford and Tesla have to work out how Ford is going to share its data with Tesla in a way that it can be verified "instantly" when a vehicle plugs in. The expectation is that this will operate as part of Ford's PnC similar to how EA currently works.

Plenty of software is needed, but an update to our vehicles shouldn't be necessary to do this.

Ok the following is the part I was missing.

Post in thread 'Can you use a non-Tesla NACS charger with a CCS non-compatible Model Y?'

Because the communication for the NACS protocol IS the CCS protocol, that is why an update is not required to communicate to the supercharger. But obviously the supercharger must be updated to talk both CCS AND the current Tesla communication standard. As for plug and charge then vs I suppose using the tab in the Tesla app to charge a “non Tesla EV”, that part is mostly irrelevant.

Mostly - I suppose if Tesla wanted to they could allow an individual to use the app to activate a charger and then verify the VIN against a database, but if they're going to go the PnC route those are definitely unnecessary steps. I expect we'll just plug in and it'll start charging. Why mess with the app at all?

I fully agree with you. I just mean that there is a difference between payment routing and the actual charging communication (between vehicle and DC charger). As I didn’t know NACS was CCS (which I suppose is also technically NACS with a different port now - that’s confusing to think of that way) it pretty much is only a question for our purposes about payment authentication. I’m really really surprised that I can’t find anything about that being standardized under NACS itself.

Aren't all the vehicles just using CAN protocol? I'd imagine it can do verification with basic CAN functions.

 

[detansinn]

The A2Z adapter is less than $200 USD. So, I pulled the trigger on one as a hedge in the event that the official adapter is hard to come by. I have multiple CCS vehicles, so no great shakes regardless. It will end up in the trunk/frunk of something.

Yes. All CCS protocol vehicles use CANBUS. Hence why cars can do plug and charge.
