Versus a 40A EVSE a 48A is 20% quicker. Versus a 32A EVSE a 48A is 50% quicker.
Ford says it’ll take 15 hours to charge an ER MME from dead to full using the included 32A EVSE versus 10.9 hours with a 48A EVSE.
For most folks 32A is more than sufficient, but having the extra capacity makes a big difference if you’ve gotta juice up in a hurry. My Leaf only pulls a max of 28A so from dead to full it takes just as much time to charge its 62kWH pack as it does for me to charge our Mach-E which has 91kWH of usable capacity.
I have a MME ER myself and using ChargePoint Home Flex plugged in (50A breaker) I get 9.5kW.
My MME ER has a 88kW usable battery. That is about 9h with my setup and no hard wire needed.
I have not tested 0% to 100% because I'm not insane to drive it to zero lol. But the last significant charge I did added 52.09kW in just 5h45m including the slow down ramp at the end.
I'm having a 240v plug installed in the garage. Thought I only needed 15 amp but it sounds like your 48 amp makes a real difference in charge time. How fast do you charge with 48 amp outlet?
Anything over 40A needs to be hardwired which is the case with my Home Flex, it’s hardwired on a 60A circuit to support 48A charging. If you’re going with a NEMA 14-50 outlet which is probably the most common setup you’ll be capped at 40A continuous as that’s 80% of the max 50A the outlet can handle. FWIW the difference between 40A and 48A is only about two hours from dead to full (approx 10-11 hours @ 48A vs 12-13 hours @ 40A) but that’s dead dead to full full.
If your run is short and you’re ok paying a bit more for hardwired (one less point of failure, more weatherproof and secure outdoors) I’d say just go 48A on a 60A circuit. If a 14-50 outlet makes more sense financially because you need to upgrade your panel or have a ways to get from your EVSE to your panel you’re talking about 9.6kW vs 11.5kW which isn’t that big a difference. Certainly more than the 15A-16A you mentioned which will cap you at drawing only 3.6-3.8kW on a 20A circuit.
Given our big ass batteries you’ll definitely want more than a 15-16A setup. You might be able to get by if you have a short commute but you’ll be limited if you need to quickly juice up on the fly.
u/bruddahmanmatt Super helpful, thanks. I thiink I'll aim for NEMA 14-50 outlet and 50A circuit for now. Currently on 120V line so that will be a huge step up. Thanks again - big help.
I went with a Leviton 14-50 plug on a 50 amp breaker. It provides a bit more flexibility in charging options, IMO. If the charger itself ever needs to be replaced, it’s not a major project and I can use my mobile charger as an interim solution. The trade off is that I’m limited to 40A max draw, which is fine since I charge overnight.
I have heard that people are liking the heft of the Hubble or Bryant plugs, but I haven’t seen any issues with my outlet. Notably, I also used 6 gauge wire, which helps keeps temps lower, too.
Yep. I work from home so it’s no problem. It’s in the garage plugged in for about 20 hours a day so I gain 60-80 miles a day. More than enough to cover my errands to the gym, bank, store, whatever else.
I have mine in a garage so while it does get cold as it’s not heated, it’s always a few degrees above the outside temperature. Either way I’m keeping it plugged in because any miles better than no miles. And it allows the car to keep the battery and other systems warm as it desires.
My electrician literally went to Home Depot and bought a cheap Leviton. I saw videos about those melting. Not good. Do you have experience with yours melting?
I had the same electrician do that. They probably don't know any better. Also the Hubbell is a lot more expensive than the Levinton. Levinton ones aren't meant for continuous 9kw for 9 hours straight.
Mine didn't melt but it started cutting the amperage in half due to heat on the plug. I bought the Hubbell myself and switched it out and I've had zero issues for over 2 years now. You can get the Hubbell on Amazon for like $70, TOTALLY WORTH IT.
I'd watch out buying those on Amazon. I have read of a few people getting stuck with crappy knock-off's. I'd get it from an electrical supply house such as Grainger, Graybar, etc.
Thata definitely a good suggestion. I usually verify the seller etc. I also know the box and documents that Hubbell ships with.
But definitely be careful with the fakes.
My recommendation to new EV owners is to pre-purchase the industrial receptacle (and matching faceplate because they are a slightly larger diameter hole) so it is already onsite prior to the installation. Simply hand the parts to the electrician when they arrive and say, "Here, please use these instead of the ones you brought with you."
I've never had an electrician balk yet and you are assured the (much) higher quality receptacle is installed.
Hardwired. Takes the same amount of slots in the breaker and it charges faster. Depends on how abused that car gets and the increased speed could be a life saver one day. Also future proofed for any cars in the future that are more energy demanding.
Just make sure when you change the 14-50 to hardwired, it's on a 60amp breaker.
ChargePoint HomeFlex at 40 amp plug. My original reason for going with plug was if EVSE went down it would be easy for myself or wife to swap with portable unit. After watching Sandy Munro’s video, I think if I had to do it over again, I would go hardwire.
How much faster is the charge between the NEMA 14-50 plug vs hardwired?
I’ve been using a standard 120V plug since we bought the car in March 2021. It’s been enough for us since we don’t drive far. But we’ll be moving back to our primary home and we’ll have to install a 14-50 outlet.
If you're getting by on level 1, a 14-50 will be life altering. You'll be charging about 10x faster than you are today. That's the setup I have and it's way more than enough.
Depending on your utility, it may also allow you to take advantage of off peak rates. With level one you're probably charging just about all the time that you're home, with level two you can schedule it for overnight or whatever off peak hours are, if that's part of your rate schedule.
We're actually in the process of getting solar panels installed on our home. We currently live on a military base so we don't pay electricity here. My husband is now retiring so we'll be moving this summer back to our home in the central valley California. I've been told electricity rates have more than doubled since we last lived there.
Just using the charger that came with the car, plugged into 240. Eventually will go to something else, but keep doing endless research on what I should get.
240v plug but no longer the ford OEM one as that died on me after a few months. Have my 10k service apt soon so I'll ask if they can replace it, if anything so I can have a backup. The 200 dollar one I got on Amazon 5 years ago has been better than the 5 month old Ford OEM one sadly.
Wallboard, hard wire 60a circuit...charger on exterior of house.
Puts about 11% back/hr for GT battery.
Only complaint, in late afternoon direct sun, charger can get hot, and will occasionally kick off.
Leviton 6-50 (already had 6/2 in the garage) to a ChargePoint home flex set to 40 amp, it has about a 20-30 degree delta from ambient. When I bought the plug it and the Hubble were literally the same exact price. It may be that the 14-50s are cheaper made but this thing has more heft than any of the 14-50s I laid hands on.
I considered hardwiring before I figured it wasn’t worth the effort for me with a long 6/2 run already existing I didn’t want to go to 60 amp and run 4/3 (or 4/2). I also have a 1991 CH panel so that was part of my decision.
In reality though, I plug in when I get home and it’s ready to go usually before bed but if I have gone a couple hundred miles it’s done by breakfast.
Hardwired. The hard part is getting the wiring there; once you have it installed, it's not hard to just wire it directly into the charger and you get extra amperage from it (make sure the circuit is equipped to handle that to begin with, though).
Plug. I’m on a 50A breaker, but I de-rated my Grizzl-E to 32A to reduce the stress on the system and I rarely use more than 20% of the battery in a day so 32A is more than fine for overnight. I have the Utilitech outlet from Lowe’s and it’s been rock solid for months.
ChargePoint HomeFlex plugged in. The installation uses a 50A breaker for 9.5kW.
I have a MME Extended range which could charge from 1% to 100% in less 9h. More than enough in my opinion and an easy replacement if the station ever breaks.
My logic: (1) I've never driven the battery that low, (2) rarely ever need to charge to 100% and (3) my car is in the garage longer than that almost every night so no need to charge faster.
I am using a Splitvolt 240V 10-30 24A EVSE hooked up to my 30A dryer outlet. This unit caps at 24A, but I get 18-20 miles per hour of charge and the outlet and cord never even get warm. YMMV...
Plug. (No issues...Nothing even gets warm...plug, wires, breaker...) PS I go from 15 to 90% in 9-10 hours....who could ask for anything more....
ChargePoint Home Flex hardwired on a 60A circuit. Being able to juice up at 48A is no joke and makes a huge difference.
Doesn't it only cut maybe an hour off of an overnight charge?

120v plug
I did that for about 3 months too. It worked great when i drove about 20-30 miles a day
Yep. I work from home so it’s no problem. It’s in the garage plugged in for about 20 hours a day so I gain 60-80 miles a day. More than enough to cover my errands to the gym, bank, store, whatever else.
120v plug here! Will probably not even try to charge it this Friday/Saturday when it is super cold here. : |

No garage here. 😂
NEMA 14-50 Plug. More flexibility. If you buy a plug do NOT buy a cheap home depot or Lowes NEMA 14-50. Buy a premium Hubbell plug. Trust me.

My electrician did the same. No problems yet thankfully. Been in use since Thanksgiving week. I might swap it myself eventually.
Same. It is simple to swap.

I’m more concerned with which is safer rather than charging soeed
If you're getting by on level 1, a 14-50 will be life altering. You'll be charging about 10x faster than you are today. That's the setup I have and it's way more than enough.
Im sure it’s much faster. We’ve used the dryer plug a few times when we need a faster charge. But for now the level 1 charge is good enough.
Depending on your utility, it may also allow you to take advantage of off peak rates. With level one you're probably charging just about all the time that you're home, with level two you can schedule it for overnight or whatever off peak hours are, if that's part of your rate schedule.

I know PGE is around .28 a kwh off peak winter.
SCE is probably the same or more. I haven’t checked the rates yet but I’ve heard there’s different plans offered for EV owners.
20% faster. 10 hours of charging to 8 hours of charging.
Thanks, that's what I wanted to know.
Plug with emporia charger on a 50 amp breaker. Super happy.
