Ford/Tesla Deal: Access to Superchargers, adapter coming, future EVs will have NACS (Tesla) port

[docwhiz]

I’m also not talking about the comms protocol. I’m talking about the switch on the vehicle side to accept dc or ac current over wires. There is physical circuitry involved at this level.

No additional switch for AC or DC. Just the same disconnects.

Tesla designed their cars to do this, please reread @DuoRivians posts on this as they are well written. After 20+ pages of messages, you still have not gotten this point yet...? NACS refers to the plug, not the car. Yet you and the other Tesla/Elon stans can't wrap this idea around your head.

The NACS and CCS each consist of plug and charging protocol standards.
Cars need to meet the standards.
(No need to call me names...)

You have no idea what’s going on… just spitting out Tesla fanboy tweets isn’t smart

Could you be more specific?

NACS uses the same plugs to carry AC and DC current to the car.

The car must decide 1/ which current type is it and 2/ route the current accordingly.

Inside the car, ie inside your Tesla, there’s separate circuitry to do #2. If it’s AC current, it routes the current to an AC to DC inverter first. If it’s DC current, it skips this route-to-inverter step.

With CCS, because the pins are separate to begin with, cars don’t need this extra #2 step. If it gets current from the AC pins, it knows it’s AC current. If it gets current from the DC pins, it knows it’s DC.

So when you factor in the entire system cost and the cost of oems having to further marry into Tesla’s IP, there are costs to installing NACS. And by no means is it an obvious cost savings.

So, back to my original point.

Yes, I want superchargers to be available to all EV consumers.

This can be most efficiently accomplished via an external adapter (along with possible Tesla Supercharger API integration with 3rd party oem apps for seamless billing). This adapter cost can be paid by consumers directly buying them.

And oems don’t have to further ingrain themselves into the Tesla sphere. There are no obvious net advantages to doing this.

I doesn't work that way.
Inside the car, the power from the NACS connector (which could be AC or DC) comes by one set of power cables and connects to both the inverter input and battery input. There is no extra step. (All cars have an AC inverter.) Tesla connects their AC inverter to the same set of power wires as the DC battery input so they only need one set of power wires inside the car. There is no extra circuitry. Just one set of power cables, not two as with the CCS.
(Someone posted a diagram of the Tesla power input circuitry a few pages back. You may want to refer to it.)

This entire response says you have no idea what you’re talking about. One more ignorant response, and just going to put you on the ignore list

Isn't implementing the Tesla API "ingrain themselves" (sic) into the Tesla sphere? What's wrong with that?

Tesla API is a one-off. Can easily be removed from within apps, just software. Much like adding another app to your phone.

Ding! ding! ding!
We have agreement! (on something)

And just to be clear there is also only one set of installed cables on CCS too. For AC Level 1/2, only cables installed are the ac pins. For DC, only the dc pin cables are installed (except for communications wire, which is there for any plug type)

No CCS cable has simultaneously both AC AND DC cables installed. One or the other

I have never said external adapter + tesla api was a bad solution.

Neither did I.
Ding! ding! ding!... Another agreement!

I'd love to see Munro actually do a full cost breakdown for the top 10 non-Tesla EVs compared to the Tesla ones for the charging circuitry including all the wiring in the cars.
