Does a CCS1 to J1772 adapter exist?

[tls]

Upgraded 2In1 CCS & J1772 to Tesla Adapter, 250KW SuperFast CCS1 to Tesla Charging Adapter, Fit for Tesla Model Y, 3, S, X, Compatible with Level 1 2 3 Charging Stations with CCS1& J1772 Plug https://a.co/d/3ahCJy8

Something like this. When used with a NACS to J1772 adapter no pins are left exposed.

Uh. "No pins are left exposed" because of that little flip up and down flap for the CCS DC pins that will have 240V on them when AC charging?

That is not a thing, "a joint CCS/j1772 to NACS adaptor". NACS uses the same pins for AC and DC charging, which means passive adapters (the only kind made) have to be for AC or DC - not both .

If I recall, the Tesla on-board charging system detects whether the plugged in EVSE has AC or DC on the pins and then throws a contactor (switch) for additional circuitry (AC to DC conversion) so that DC is applied to the battery in either case.

So if the CCS is the FCSP the output is AC up to 80A and the pins will only have AC on them - the DC pins on the FCSP are for powering your house from the Lightning via the HIS if you have one - no DC voltage is one them from the FCSP.

The item *CCS/J1772 to NACS adapter) description says it is rated for up to 80A at 250V AC.

The NACS to to J1772 adapter says the same thing " Our adapter boasts a maximum power output of 80A and a voltage of 250V."

Have two adapters in series could cause issues (resistance issues) so using the full 80A capacity of the FCSP is probably a bad idea.

Can the extension cord on the FCSP be exchanged for one with j1772?

No. The FCSP is purpose built for the bi-directional power backup. If you are not using the bi-directional charging/ home power backup, your best bet is to replace the FCSP with a different unit.

The other solution posted here is to use an extension cable and modify the one end to fit the CCS plug on the FCSP. That *might* work for you. Unfortunately many vehicles that have only a J1772 port are not compatible with this hack as they don’t support the necessary communications. The FCSP uses CCS signaling. There’s been a handful of reports of people modifying their J1772 to Tesla adapters to fit the FCSP as well as a few trying J1772 extension cords and finding that their older EV that doesn’t have CCS support still won’t play with the FCSP.

Yes I believe you could replace the CCS cord with a J1772 cord. I haven't tried it though.

If you are not using the DC pins for Home Backup with the Home Integration System you don't need the CCS cable and plug, just the J1772 portion/wires/pins.

CAVEAT: Only try it if you know what you are doing, and of course with the POWER OFF!

You would want a heavy-duty J1772 cable rated for 80A one if you plan on using 80A J1772 charging. Or an appropriately rated cable for whatever lower amperage you will use.

You'd have to wire it up properly of course, so consult the FCSP manual images to connect the correct wires to the correct terminals.

You could trace the existing CCS J1772 pins to their ends inside the FCSP before changing cables to be sure you get them right.

The image shows the FCSP without the 240VAC from the house panel hooked up. The CCS wires are shown attached to their respective terminals. The red and black wires coming from the CCS cord are the DC wires to carry DC from the Lightning to a home integration system (not connected in this picture) via the FCSP.

The AC out to the vehicle (needed for charging the Lightning battery) is provided by the Blue and Brown wires, and the Green wire is ground. The other smaller wires are signalling wires.

The CCS pinout is this:

The top part is the J1772:

So the two Hots (Blue and Brown) connect to L1 and N, the Ground (Green) to PE and the PP and CP control signal lines to the appropriate terminals inside the FCSP.

The J1772 cable will not have the DC wires that the CCS cable has of course.

An overview of the FCSP wiring from the SunRun documents is above.

Obviously do the change with the power to the FCSP OFF!!!

Another solution to charging a J1772 vehicle is of course to use the Ford Mobile Power Cord - that's what I do with my 2012 Leaf at 30A (or maybe 32A).
