Adapt Ford's 120v charge cable to 240v

Has anyone adapted Ford's standard 120v charging cable they give you with the car to a 240v circuit? I just got a 2017 FFE, and I have a level 2 cable on order, but I can't keep up with what I need in the meantime with the L1 cable. I have plenty of 240v circuits and it would be no problem to whip up an adapter tonight to supply the standard charger with 240v (I think I even have one laying around), but I don't want to blow it up if some of the internal circuitry is 120v only.

Since they sold the Focus Electric in Europe, and in my experience most electronics are safe from 90-250 volts anyway, I suspect it would work but I figured somebody here must have tried it already.

Thanks!

Part number of EVSE is FM58-10B706-AJ

Not sure if anyone tried it, the topic has come up from time to time--search the forums here.

I have. Made a 6-15 to 5-15 adapter cable. Go for it!

My 2017 C-Max is currently using one set up like this full time (same convenience cord as the Focus Electric fyi) and it's been plugged into 240V for 6 days with no faults. I had tested this arrangement with the Focus Electric's convenience cord some months back with success.

I went ahead and made a couple of adapters for 14-XX universal (14-50 plug with missing neutral blade) to 5-15 and a 10-30 to 5-15.

Awesome, thanks. I searched and came up with nothing. I assume it charges twice as fast? I'll give it a whirl, just wanted to make sure nothing pops or sizzles.

Welp, here we go. Converted an L6-20 to 5-15. Seems to be working, FFE has charged about 5 percent on it so far and the projected time to full charge dropped about 11 hours from the 120v setup. Without putting an ammeter on it I'm assuming I'm somewhere near 2900 watts.

Fully charged this morning! I think it would probably be something like 14 hours for a full charge vs 30.

what year FFE is that from? Is that a European EVSE? I took mine from my 2014 apart and there is no way it would handle 240V.

no idea what he has, but I have a USA 2017 FFE. My C-Max is also a USA 2017 model with the same convenience cord. Judging by the charge times he's quoting I'm assuming it's a 2017.

Curious though, what was it about the 2014 cord that gave you hesitation? What parts appeared incompatible?

Correct, mine is a 2017, and it's just the portable EVSE that came with the car.

Remember the amperage will be the same - most computer cables, power supplies, etc work worldwide on either 120v or 240v. It's generally only things with motors where you run into issues adapting on to another.

Of course it's not "rated" for 240 because of the 5-15 plug.
