1Kw charging rate from 110 outlet at home?

[phasornc]

Just got my MachE 2 days ago (California Hwy 1). When I try to charge at home by plugging in to the 110 outlet, I get a charge rate 1 kW. In 8 hours and 15 minutes of charging the MachE added 9.8 kWh. I got the same result with my Escape PHEV charge and MachE "mobile charger". Shouldn't I see a slighter higher rate than 1 kW and 28 miles added after 8.25 hours on the charger?

Btw I dont' usually drive more than 25 miles in a day so this would be fine, but i assumed I'd get a little more than 3.3 miles per hour charging. I got about 5 miles per hour of charging on the Escape. Doe this charge rate seem normal to you? FWIW it's between 50 and 70 degrees outside for the past 2 days ... so no extreme hot or cold.

Edit: I jumped the gun with this suggestion

Yes, it’s simple math.

You’re never going to get more than 1500W from a 120/15A outlet to begin with, since that’s the maximum continuous load for such an outlet, not the full 1800W it can give as non-continuous load. Same reason all space heaters max at 1500W. The charging process isn’t lossless and there’s some rounding in the display so 1kW ends up pretty normal on the mobile charger on a 120 outlet. Anecdotally, I get the exact same number displayed if I use such an outlet. The amount of miles that equates to will vary depending on conditions, including how you drive, your last few driving sessions, outdoor temperatures, pack temperatures, etc…, so the about 3mi/hour number Ford gives should be taken as just a very rough estimate. Your mileage may vary, as always.

These are normal rates for Level 1 charging. Only about 1kW gets to the battery.

You'll notice your 120v outlet will get warm as well. 120v is less efficient than 240v. I get the same numbers as you with my 120v so you're getting the best you can with your setup.

Ford advertizes a Level 1 Charging rate of 3 miles or range per hour. The calculation the car does will vary based on driving history (look under “Trips” on the app screen) and outside temperature. So you’re actually getting a bit more than Ford advertizes.

A standard 115v outlet is current limited to 15 amps. 115 x 15 = 1,725 watts. So your absolute maximum AC power output is 1.7 kWh.

Take 10% off for efficiency and you get to 1.5kWh. You can use that to estimate charge times.

If your electric panel is in the garage, you can add a 220v/50A outlet for fairly little money. I drive 4,000+ miles a month, so for me it was worth it.

I had a c-max energi from 2013 to 2021.....a Select RWD SR from 2021 to 2023 and a 2023 Premium RWD SR from June 2023 to the present......all were charged with the included mobile charger 99.95% of the time......with both the Mach e's I average 5.2 m/kwh.......when I charge at home w/120 line, the estimated miles added per hour is about 5 miles.......I believe the car understands your driving habits and adjusts estimated range based on your driving.....I had 28,000+ miles on my '21 Select and now 6000+ miles on my '23 Premium so I think my info etc is pretty good....

I believe once your car "learns" your driving habits, your estimated miles added when charging will improve close to what you are used to.....I assume you do not speed race when driving you 28 or so miles/day, haha......

Welcome to Mach E ownership.

Yes, as others have said, a bit over 1 kW is all you can expect out of L1.

Two video recommendations for you:



This second one has important recommendations for safely charging on L1 or L2

 

[dah]

The miles added calculation, from what I recall, is the difference between the estimated range of the vehicle at the time you plugged in vs. the current estimated range.

Because of that you can get some weird values in that field, especially if conditions are variable over the duration of the charge.

As Gator Growl points out an upgrade to your garage could be the fix you need .Best money I ever spent .
***There's still a tax credit of 30% up to $1000 on charger and installation . ***
Your state or electric company might have offers also .

The issue is not losses in the normal sense but that the car consumes energy in the charging process. L1 is about 70% efficient and L2 is in the 90% range. The faster you charge your car the less ancillary charge usage. Slightly more heat loss at higher current but more than made up for by reduced charge time.

And that’s why we installed a L2 at home. We had to upgrade our panel but was something that needed to be done anyway

I have found that FordPass rounds down. So 120V * 12Amps / 1000 = 1.44kWh I found my LvL 1 (non Ford) gets about 85% efficiency but FP app shows 1kWh even though when it’s done charging it is more like 1.2kWh.

I see the same with LVL 2 - just 6 instead of 7kWh.

I find with Ford they do everything conservative. To include the rounding of charging.

I got the same result with my Escape PHEV charge

So just curious, did your Escape PHEV charge faster?

I agree with most of the other replies that installing a 240V outlet is the way to go. It took me a week to get an electrician in, and it seemed like forever.
