Seems the RWD models see much high numbers. Mid 5s?

I'lll get mid 5's to 6 every now and then. I mostly sit around the 4 range, sometimes lower, some times higher. For example, tonight we went out to dinner, was 60 degrees when we left the restraunt and I had my wife with me. HAD to turn on the heater, OUCH!!! First time I've ever had the temp set where it had to use that. Think I got 2.3kWh coming home, when I was at 4.2kWh when I drove there lol

My AWD averages about 3.5 round-trip for rural driving (about 10,500 miles now), which includes a ~1.5 mile 8-10% grade downhill to start and uphill to finish.

Ya I don’t think 3.9 is far fetched.

So this morning I forgot to reset my trip 1 cause I wanted to track my mileage. Come to find out it showed the exact info as trip 2, 3.9mi/kWh. I was already driving or I would had taken another picture.

So I reset it mid drive, today was not a typical day though. Took one kid to school came back home took another came back home for a meeting then went to work.

Bet you can’t guess what my mi/kWh was…. Stupid car mocked me, it was showing 4.1 but updated when I pulled into the parking lot lol

Car is still showing me 215 miles at 78%, which is so incredibly wrong.

This has been answered correctly more than once, but I just want to point out the latest notice from Ford. Note item 2 - keep it plugged in when parked (if you can of course). So the answer to the OP's question is: yes, per Ford, you should plug in every day and leave it plugged in all the time. And as others have said, 90% is the recommended charge level unless you need the extra 10% for a long drive.

Tips for maximizing your BEV's range in cold weather
  1. Park in a garage wherever possible.
  2. Keep your BEV plugged in when parked.
  3. Precondition your vehicle using departure times to warm the cabin and the battery while plugged-in.
  4. Use the heated seats and steering wheel (if available) for primary heat to reduce energy consumed by the Heating, Ventilation, and Air Conditioning (HVAC) system.
  5. When charging, turn off the heater.
  6. If your vehicle is covered with snow, brush all the snow off before driving to remove extra weight and drag.
  7. Keep your driving speeds moderate as high speeds use more energy.
  8. Ensure your tires are at the proper pressure.

I think I'm just going to go with 60-80% (which translate to 50-70% actual or so) since I don't need 100% (or even 90% honestly).

I think even though it's in a manual, it's not perfect because manual/manufacturer creators look at everyone's use case.

If you don't need the range due to work from home now or you telecommute anyways, even though perfect isn't needed in the grand scheme of things, maybe it's all for the peace of mind that we're babying the battery even though it won't matter one bit.

That makes sense and of course you should do what is best for you. But Ford recommends keeping the car plugged in when it is parked. You may have read reports in this forum of cars with dead LVBs. The LVB can be maintained properly if the car is plugged in. Also, you can precondition the car and maybe even OTA updates are more reliable (just a guess). Whatever the benefits, Ford recommends it so maybe the answer for you is the set the charge point to 80% and leave it plugged in at 80%. But if your LVB dies because you have been telecommuting and not driving, it might have been fine if plugged in. Something to think about, anyway.

Yeah, I plan to just leave it plugged in...I think every study has stated Lithium Ion batteries like 50-60% best?

If you can keep your battery 50-60% it will be easiest on the battery, but I really think the difference is negligible unless you plan to keep the car for 30 years.

I just had a great example today why you should keep it charged to 90%. I had to make a four hour drive to NC that was totally unexpected and since my car was at 90% I didn't have to worry about making it. I hit the road and drove for over two hours before stopping at the planned fast charger. If it was charged to 60% I would have had to make two stops instead of one.

Very true, if we only owned an EV. I'd take our ICE and not sweat it if I had to go 300+ miles. That won't work for everyone of course.

I *wanted* to take the EV. I want to drive my MME everywhere I go. There is an ICE car sitting next to it in the garage, and my wife suggested I take that. No way! Round trip I drove 560 miles, stopping at an EA charger on the way down, and the same one on the way back. Slow charge at the hotel last night. Anyway, I am very glad I was able to start off with 90% instead of 60%.

When I try to get my Ford charger info into Ford Pass I get a message that the numbers I input are in error. Anyone have and solve this problem??

I don't understand the question. You don't need to enter any numbers into FordPass related to the 32 Amp charger that comes with the car. Are you referring to the wall charger you can buy from Ford? In that case you probably want to register it with the app, but I don't have one of those so I really have no idea.
