Strange drop in miles after Electrify America

[thomaswfirth]

I do most of my charging at home (I'm retired) and decided to record vehicle odometer mileage, Percent change and resulted mileage so I could gather some data on the trip. I had an interesting occurrence on the trip. I left my home in Scottsdale Arizona and stopped to charge my 2023 Lariat at an Electrify America in Tucson Arizona to 90% charge and that produced 264 miles when completed. I left the charger and before I even got out of the parking lot, the mileage dropped to 211. I had traveled less than half mile to the freeway when I noticed this. I thought that very odd at the time and continued on my trip. On my return back home I stopped an another electrify America in Benson Arizona and charged to 90% again which resulted to 263 miles. the same thing occurred but it dropped to 235 miles.
Has anyone else had this anomaly?

Everyone.

When you charge to 90% (why aren't you doing 80%), the truck GOM shows a factory default for 90%. Then, as soon as you start you trip, the navigation (I assume you had a destination set?) projects more accurately.

You should know the miles per kilowatt you have been getting on your trip so far. Take that, x battery size SOC% and you have your range assuming the next leg is the same weather, and road conditions (not now climbing hills or driving 80 instead of 70).

it's nothing to do with ElectrifyAmerica or any DC Fast Charger - it's your 'guess o meter', which is never correct to begin with... as we've all learned over time.

Ignore the guess o meter, other then a very rough ballpark for shorter trips.

Your miles per kW is what you need to focus on. If you are averaging 2.0 miles/kW at 90% you can go approximately 235 miles before you are pushing. Then figure 11 miles for each 0.1 miles above or below. So 1.5 miles will only get you around 175 available miles where 2.5 miles will get you 295 available miles.

At 80% it is 210 miles and 10 +\- per 0.1

Electrons from EA are inferior to electrons from FCSP home charging. Ford will not tell you that but it’s been experienced by many on this forum.

I’m getting carpal tunnel from typing “Ignore the GOM” so much.

It's insane how much everyone pays attention to this thing. They've been on ICE cars and trucks since the 80s, called DTE (Distance to Empty, I think), and they are as terrible at calculating as the GOM in our trucks is, but with ICE, everyone just ignored them. Maybe Ford just needs to not shove it in our face so much.

Well I agree the GOM isn't worth it, and the DTE is usually the same EXCEPT Ford got it right on my Escape Hybrid from way back to 2005... To this day it hits the mark as to how many miles are left "in the tank and battery" highway or city or both... @ford you should just yank the the software algorithm from the Escape Hybrid from 2005 and plug it in to your EV's. Gone would be the GOM complaints...
