Would a NACS retrofit allow V2H?

[intensifi]

If so, I’m in.

I would normally complain about ditching the CCS connector, but I have seen those of small frame struggle with them at public chargers (EVSEs).

I’m thinking the best solution is CCS on one side and NACS on the other. And if one of the charge port doors is open, the other is locked!

I love the idea of having the NACS port located on the rear of the Mach-E like Teslas currently have. As we all have backup cameras (& most have 360 cameras), backing into a sport is not an issue and is safer than pulling in. This location also enhances compatibility with Tesla Superchargers, that are configured for charging with this port location.

There is not going to be any retrofit of the Mach E GT you already have in your driveway.

The option that will be made available to existing Ford EVs will be to buy a giant CCS dongle that will attach to you the SuperCharger network. Essentially, the same thing as the "magic dock" that Tesla has installed in a few select locations already.

The NACS port will be available on new vehicles only. V2H would have to be designed into the charging system of the car, but its not something that would be enabled automatically just by having an NACS port.

I purchased an Lectron adopter for our MME. Am I correct in that they are good for destination chargers not Super Chargers?

Yes.

I'm wondering if it will even be a dongle. My coworker just got hot a CCS female, NACS male adaptor to accept a CCS cable in her Tesla. It's just a plastic adaptor (no cable) that she inserts into her car's charge port. That's what I figured the reverse version to look like. Hers is a Lectron.

I think the one that will be made available in 2024 will come from Tesla or Tesla and Ford to insure the handshake works. Just a guess.

V2H for the Tesla connector exists only on paper as far as I know.

yes, was thinking the same thing. Just a reverse of the product you mentioned. There will likely be a chip inside that handles the handshake, so the product will be a collaboration with Ford and Tesla. There won’t be any ability to have even a short cable extension, because then cooling that cable becomes a problem. I still think of that as a “dongle”, but maybe adapter is more accurate.

TeslaTaps have a chip inside them. You plug them into the Tesla Destination charger, wait 30 seconds, then plug into the car's J-1772. The internal electronics have to energize, start up, and then are ready to conduct the handshake with your vehicle.

I've never understood why people would buy a Lectron when the one from Tesla is basically the same price.

NACS does not negotiate or allow export as far as I know.

However, you CAN already export from MME via the 12v connection points.... only about 1500watts though, and only while MME is 'on' so that the on-board dcdc can pull energy out of HV and supply the 12v connection points.

In the simplest form, all it takes is a decent 1500watt inverter (under $300) and jumper cables

@dtbaker61 -- Do you know if the car can be in accessory mode, or has to be fully started (like what FDRS calls "engine on")?
I suppose it has to be fully on so the HVB is connected to the drivetrain & DCDC?

as I wrote up in the thread on the topic:
- engine must be 'on', not acc mode
- auto-off timer disabled so system stays 'on'
- all doors closed
- HV SOC>15%
....otherwise the HV will not 'charge' the load it sees on 12v connection points.

Maybe because $20 is $20 Who knows why people do anything these days. And actually, I only think hers was a Lectron. Maybe she ordered the Tesla one.

i don't think it is an actual chip - teslatap's website mentions a "bypass circuit". teslataps require a 30s wait after plugging into the Tesla Wall/Destination charger before plugging into the car (as does my lectron). my guess is the adapter causes the EVSE to start its PWM signaling when it is connected and the 30s wait is to make the tesla EVSE timeout and then it will restart when it is connected to the car.

tesla EVSEs use the same PWM signaling used on J1772 spec ports so it should generally* work once they sync up. i'm pretty sure these are very simple circuits without any chip communicating on the pilot pins.

* it appears gen3 tesla EVSEs have added an access control mechanism via a firmware upgrade that will require a digital communication between EVSE and car when in one of the restricted modes. this is probably a proprietary method using CAN or PLC communications since it needs to detect "authentic" teslas or, in "Authorized Teslas Only" mode, pass the VIN. both restricted modes may pass the VIN - i haven't found any details there. if you run into one of these gen3 units in this mode it most likely won't work.
