The first 10 pcs went into test units plus a couple kit bundles and prebuilt stations. We expect the 90pcs to ship on February 2nd. I will work on the product in the store so the NACS cable can be pre-ordered.
We have recieved our first 10 - 48A NACS cables. Another 90 are on the way.
@pir8radio & Alexander Give me a day or two and I will create the store product listing. At the moment the cables are options on the Kit Bundle and Station.
Sure does. The VCC line connects to 3.3v. The easiest spot to tap is the WiFi / WiFi LCD module.
There are also NTC temperature lines for each power line. We will add circuits on ADC pins in the future to monitor pin temperaturte.
Here is the NACS cable by itself in the store. We currently have 5 available flown in and 90 on the way.
We have a couple left from the initial 10 and the remaining 90 are on a boat.
My understanding is the communication expresses the vehicle ID, not the credit card information. The value of skimming information would only come if someone wanted to then replicate the vehicle ID to charge their own car. I can't imagine a pirate going so far just to steal a charge every now and then but this is a fair point.
OpenEVSE will offer NACS as soon as we can find a supplier. Tesla cables sacrificed from a Tesla Mobile Connector or HPWC work perfectly on OpenEVSE.
That is the one I'm using! In fact, I also tried (and will continue to) get the HA community to adopt it as the official integration.
Right now it's broken because I have the new LCD, and the version info isn't in the expected format (sem-ver?). I can read data, but changing values throws an error. Any word on firmware updates yet?
NACS cables now in stock...
25 feet
48A
With transmitter for tesla charge port doors.
@openEVSE Support send me one man... tell me what i owe you lol..
Need an extra guinea pig pig? I have an OpenEVSE 50A + suitable wiring + a Rivian R1T + a NACS -> J177s adapter + and a cable I need to replace that's probably only should be doing 32A.
I've had a couple of Tesla gen 2 mobile adapters fail over the last 3 years charging a Think City using a NACs to J1772 adapter. This setup works fine, but the Think doesn't release the adapter contactors at end of charge. Must be something to do with the way the Think treats the CP line after the charge is complete. The first mobile charger I opened up had a failed AC contactor block. I suspect the second will be the same.
I just ordered one of the new OpenEVSE advanced kits and plan to use one of the salvage Tesla mobile charger NAC cables for output. I'm hoping to put a NACs connector on my converted Chevy S10 to match.
My My Tesla NACs cable questions are:
for the power wires, I have blue and brown. For AC, is the brown wire neutral and the blue wire hot (120 vac) and both hot for 240 vac? Green with yellow stripe should be safety ground.
The signal connector has 4 wires:
orange = proximity pilot
purple = control pilot
blue = +3.3vdc to power the RF transmitter to open the charge port door
white = I have no idea what this is for. It doesn't seem to have any continuity to anything. Is it the 3.3vdc return (-) or something else?
thanks!
White on the Tesla cable is NTC temperature sensor it is 12K at room temperature and goes down as temperature goes up.
We can add connectors to our NACS cable to make it a direct replacement for Tesla HPWC Gen 3.

Whelp. With CCS dying in the US. We *really* need OpenEVSE to source an NACS cable or connector for existing OpenEVSE units.
