Has anyone successfully charged a tesla with the FCSP?

The assumption is that you have the adapter for CCS to NACS. Which I do have.

I would love to be able to use the 80A option, with the FCSP, to charge the truck. I don't want to disconnect the existing tesla charger without knowing the answer to this.

I live in Austin, TX if someone is willing to help me test this out.

Thanks

There should be nothing preventing it from working. Level 2 chargers are effectively smart switches. Whether or not you can charge at 80A would depend on the onboard charger in the Tesla's capacity. Though I've only recently bought the Lightning as my first EV, I've followed EVs since the GM EV1, and this is my current understanding of how it works.

A CCS to NACS adapter will not work for L2. It routes the DC pins.

Some have tried modifying a J1772 to NACS to fit. It worked for some but not others. There are a few threads on this.

Interesting, so for L2 AC it doesn't use the the 'DC' pins at all? Or is it that the CCS uses separate pins for AC charging and that's why it has so many pins...I think I just answered my own question....

Yup. The bottom two dc pins on the FCSP are only used for back feeding your home with the home integration system.

I actually meant the dc pins on the NACS when I wrote it, but there would be no reason for tesla to not also use them for AC also and just switch the path with a relay type device when, I'm assuming, the power control on the charger tells it that it's AC power, less wire, lower cost, quite elegant really. So the only way for there to be a safe and true AC and DC compatible adapter in this configuration would take electronics in the adapter itself increasing size and cost. The dumb version already looks quite large.

I am aware of people who have used the Ford Charge Station Pro to charge Tesla vehicles. It typically requires that you physically modify a J1772-to-NACS adapter so that it fits the FCSP's CCS plug. I believe I saw a reference to someone who was producing an adapter specifically for this use case, but cannot find the link right now.

While a standard CCS-to-NACS fits the FCSP plug, the adapter will not work for charging. This is because J1772/CCS uses separate AC and DC power pins, while NACS uses the same pins for both. A CCS-to-NACS adapter connects the large CCS DC power pins to the NACS power pins, leaving the J1772 pins disconnected. On the FCSP, the CCS DC pins are only for power output from the vehicle's battery to a home inverter -- AC charging power is on the (disconnected) J1772 pins.

A standard J1772-to-NACS adapter has the correct connections, linking the J1772 AC power pins to the NACS power pins. However, the adapter won't physically fit the FCSP charge plug, because the CCS pins on the connector interfere. Some folks have physically removed the a portion of the adapter's sidewall to clear the FCSP CCS pins, and report that this does work.

my other vehicle is a PIH, so it just has the J1772 pins. Looks like the only way to use my FCSP would be to get this Thunderstorm Lite and the plug a NACS to J1772 (like one for a Tesla Destination Charger) onto that?

Is your Lightning a 2023 or earlier? You might want to update your profile with that info. 2024+ models are limited to 48 amp charging.

If you have a 2022 or 2023, another option is to replace the FCSP with a J1772 80-amp EVSE if you have no intention of installing the Ford Home Integration Kit. This would maintain your ability to charge at 80 amps and open options for other J1772 EVs directly and NACs EVs with a normal adapter.

I never got it to work in the year we had a Y Performance. I had the same adaptor above, the unit would click like it was communicating, then fault. Ford couldn't answer why it wouldn't work and basically stonewalled me with "It's a Tesla software thing they need to enable" and Tesla of course said it was a Ford thing. We did solve it though, sold the POS Tesla, I hated that appliance of a car. Works fine with both Lightnings and our Chevy Bolt as well. Regardless of which side the fault is on, I don't think you'll get it to work, sorry...

Chances are you had a bad adapter.
