Hey Ford, here is a suggestion...put a male 110v plug on the charging bay area...

[TheFDMayor]

I don't know about anyone else on this sight that lives in the frozen tundra, but it is a pain in the butt to have to plug in the Mach-E to a 110v outlet when you have to use the OEM charger with the 110v converter on it. It would be much easier if Ford would install a mail 110v plug on the charging bay area that you could just plug an extension cord into to keep the car plugged in during the cold days at work, a friends house, etc... They have them on big rigs to keep them warm, so its not like its new technology. Would sure make things a whole lot simpler when a level 2 charger is not available.

Thing is, an extension cord doesn't have any of the safety features an EVSE has. You can plug in your car standing in a puddle with bare feet and it's fine because there is no power at the plug until you plug it in and the car signals it is ready to charge.

Every car up here in the Tundra has a 110v plug on it, puddle are really a concern at -15f.

Basically you’re asking for a built-in level 1 EVSE.

Engineers are still scratching their heads on the idea of a heat pump and here you are asking for a second outlet.

Anyone that would like a built in Level 1 for these cold weather reasons, doesn't want a heat pump....

For engine block heaters that pull a lot less.

The box "converting" from a wall socket to EVSE connector is not a charger or a converter in any way. It is just a safety device that
1) Can shut of power in case of failure.
2) Will tell the onboard charger how much power it can draw.

The actual electrical connection is pass-thru directly into the connector, just via a relay that can shut of all supply. It is the same hardware that is inside a wall box. it is the on-board charger in the vehicle that do the work of regulating charging.

The safety requirements within these are a result of experience, it has features like
1) It will not allow charging to start unless ground is detected and is working properly (it will measure voltage drop, it will measure currents, it will make sure there is no current going to ground, or it will shut of charging immedately).
2) It will know which kind of socket has been connected. It will tell the vehicle how much current it can draw based on which kind of socket is connected. If the vehicle does not comply it can shut of the relay to prevent damage.
3) It will have temperature sensors at both sockets. Monitoring the temperature within the socket to limit or shut of charging in case temperature is rising from a bad connection. Bad connection = Fire!

An extension cord can have those features, but most don't, and even indoor extension cords might get damaged by cold temperatures, water, UV radiation, etc. making them unsafe for this kind of use. Some of those connectors are not even water resistant. Some features could be implemented inside the vehicle, like ground verification, but even so it is a small price to pay to prevent possible fires and injury from damaged equipment to require this to be handled off-board.

Yes!...yes I am...

So what happens when you plug in the 110v charger to an extension cord to reach a plug on the side of the building? I am sure Ford can figure out how to build in safety and charging protocol in a 110v male adaptor...I know they have room behind the frunk to place it.

Ford warns against using extension cords.

If you must use one, at your own risk, be sure to plug in the plug pigtail to the EVSE, then the extension cord to the wall outlet, then the EVSE (w/ plug pigtail) to the extension cord, and finally the coupler to the vehicle. Unplug in reverse order.

Here’s a suggestion: install a permanent level 2 EVSE if you live in the frozen tundra so you don’t have to fiddle with the mobile charger. Takes me less than 4 seconds to plug my MME in each night. Fiddling with a 10 or 12 gauge extension cord seems like more of a pain.

Plugs wear out, it's a lot easier to get a new EVSE that to replace the receptacle in a car. Repeated use, strain relief in case of cord yank, and safety are concerns. Daily repeated use in all-weather conditions is what the J1772 plug was designed for. Rain-protecting the connection is also required. With an EVSE, the live 120V connection would be made in a weather protected receptacle box per current code, with a 120V plug in the charging door it would not be weather-proof while in use and would require the use of an extension cord. Extension cords become problematic at higher currents and can cause fires, which is why they aren't recommend to be used for EV charging. You're supposed to plug the EVSE directly into the outlet so the cord is monitored and protected.

Just because we are used to 120V plugs on cars for block heaters, etc doesn't mean it's a good idea for EV charging. J1772 is the superior solution for safety and reliability.
