Not quite sure what you're asking.

The car will only take the voltage it will handle. I have an EVSE that can deliver 240v. When I plug it into a Volt the Volt, which can handle 240v, charges. If it couldn't -- and I don't know of any plug in that can't handle 240 volts -- it would throw an error message and wouldn't charge.

Note there isn't any conversion between 240v and 120v. They'd both be AC. The conversion to DC would be effectuated by the charger in the car.

Maybe he's asking if a 240V charge cord can be plugged into a 110v outlet? Or, uh, something.

The OP needs to clarify his questions. I don't know what he's asking either.

Yea, what exactly is the question? I'm guessing any car with a J1772 plug can handle 120 or 240 volt charging input. The onboard hardware and software takes care of the details.

My take was the OP was asking about plugging their 110v EVSE into 220v.

If you have a 4 wire 220vac outlet you can indeed run a simple adapter for a pair of 110vac outlets, but why would you want this?

Reading through the original question, my take is that the OP perhaps discussed using the OEM 120v EVSE (gen 2) and how it's compatible with 240v. With his boss assuming, or implying that her factory EVSE will also do the same thing. Having no knowledge of the Ford EVSE, I can't confirm if it too would be dual voltage capable.

She would know after a few seconds.

Unless they say 90v-240v on the device it probably won't work

My boss thinks she can do this for her Ford Fusion. In layman's terms what can I tell her? Thanks.
Which Ford Fusion? The only model that can use an EVSE is the Fusion Energi. As other here have posted, express yourself more clearly and with the correct information. BTW, since the Energi uses the SAE J1772 standrad for charging, it may use either. The onboard charger does the rectification and conversion from AC to the DC voltage for the Energi battery.

The car will happily accept 240V with no issues. Whether or not the charge cord (EVSE) will take it is a good question. Some generations of Volt cord will go up in smoke, other (more recent) ones are fine. I have no idea if the cord that came with her Energi will have issues.

Title actually implies the opposite. Using a 240v on 120v.
Look in the clouds. I see an elephant, and a train. What do you see?

Until the OP responds with details, we are all just imagining what they meant.

Clarification: The Volt can charge faster by charging from a 220v plug by using a pigtail adapter that converts the 220 into a 110v plug. The Volt charger plugs directly into the 110 plug. I think the adapter was made by Chris that I bought off Etsy. Given this setup would it work for any electric (I'm sure it wouldn't but I don't know why).

Your EVSE just happens to be capable of handling 120V OR 240V. Not all EVSEs have that capability and would be damaged by it. That is the reason your friend cannot do that. However, your friend could do the research necessary to confirm whether or not their EVSE is so compatible, or buy one that is.

According to ClipperCreek's charts, the Ford Energi cars will benefit from 240v charging. The question becomes will the Ford delivered EVSE handle 240v input.

Inside the EVSE there are some electronics. The exact electronis installed varies between different units. Some of them are capable of handling 240V, and some of them were designed for 120V with no thought of 240V and turn to smoke if you use an adapter to force 240V into them. I think it mostly centers around how the EVSE converts the 120/240V into 12V for signaling and processors - some units have auto-switching universal transformers, some don't.


The most useful thread I found on the subject is here:

http://fordcmaxenergiforum.com/topic/1895-can-you-use-the-regular-charger-in-a-240v-outlet/

Lot of uncertainty, but no one saying they thought it would work.

Careful in what you say! Your "clarification" applies ONLY to the Gen 2's EVSE described by Chris TX. It does not apply to the Gen 1 EVSE. And your clarification should contain the caveat the the EVSE must have the P/N that Chris TX tested. You don't want someone taking your clarification verbatum and smoking his/her EVSE.
