Mileage understanding

[FirstF150InCasco]

Right,

Lets assume I am driving perfectly per the manual and "I should" get 300 miles to 100%. I understand variable like speed and all the other stuff (that effects ICE cars to) and I'm not really talking about that.

My perdicted range on 100% charge the other day was 249 I think. OK. BUT regardless of what that says I should still get 300 miles on a 100% charge, correct? I really don't care about the predicted mileage based on .......

No. As others have said, you will not get 300 miles.

Lets use your analogy, and I'll use real world. I have a goldwing as my primary vehicle. It has a 6 gallon tank and I know I can get 40-45 miles to the gallon, I know because I have driven it to 240+ miles. This is my starting point. SO, I know I can always get 240 miles on a full tank.

So every time I top my tank off I will get 240 miles. Now that is effected by rain, wind, co-rider, trailer, etc. (within that 240 miles), But lets assume I am by myself, when I top my tank off again, I know I can get 240 miles.

This is my point, everytime I top my tank off my starting point is always 240 miles.

But for some reason the computer in my truck is telling me everytime I top my battery off to 100% I will NOT get 300 miles I will get a different value each time and each time it is always lower. I want to know if 300 miles like Ford and the EPA is my 100% starting point

When I got my truck in September I got 299 miles to a 100% charge and now I get 249 miles to a charge, I don't want a average of my driving habits, I want to know what estimated mileage will be on a 100% charge each time I top off the battery. That is my point.

Why are you in denial mode? Clearly, an EV is not for you.

I believe terrain makes a difference as well. If your trip is all up hill, one way vs. a round trip covering the same terrain each way vs an all downhill trip, your results will vary.

Sorry for beating the horse, but as a fellow motorcycle enthusiast, Harley Davidson didn't promise me I could always get a specific range for the 6 gallons of gas when the tank is 100% full.

I ride in variable conditions, I stop for energy when its called for, not when the tank runs dry.

I used to have one of those! But mine was a '14. I swapped it out for a K-1600 a couple of years ago. Now my RH grip is no longer just a volume control.

The GOM (Guess-o-meter) is designed to give you a rough idea of what range you have, it is no guarantee. It uses an algorithm that takes your recent energy consumption history, with a heavier weighting on the most recent history, to come up with a somewhat educated guess of what sort of range you could expect, assuming that driving conditions and habits remain pretty much what they were the last time you drove the vehicle.

This is no different than how it works with a gas vehicle, but the variances are less noticeable for a number of reasons, not the least of which is the fact that an internal combustion is, at best, about 30% efficient. Thus 70% of energy is lost pretty much equally every time the vehicle is driven, and the variances only affect 30% of the energy in the tank. With efficiencies in the 80-90% range for EVs, just about any change in the driving conditions will have an effect on range.

You could have driven much of the last 400 miles in super-ideal conditions, but if the last 40 miles of that was way below optimal, the estimated range after recharging will be based on most of the conditions going forward being more like those last 40 miles.

Why doesn't the computer give you the estimated mileage on 100% period and then another screen or another setting give you the estimated mileage with all the variables?

I think this paragraph is what is causing the confusion. If you are confident that you'll get 300 miles with 100%, regardless of any variables, why does it need to show on the screen? That's in the manual. The screen shows you the second option, the one with all the variables.

You have a chart, great, I don't use a chart, I have a baseline of 240 miles on a 6 gallon tank. I developed the baseline from riding, I can get more I know that but I know when I fill my tank I am able to get 240 miles. Each time I fill my tank I have to assess do I have a trailer, 220 miles, do I have a co-rider, 240 miles, is it raining, am I in the mountains, etc. I understand variables when riding and you assess those on the ride. BUT my baseline is 240 miles on what I consider a normal day I will always get 240 miles on a tank.

But the computer on my truck doesn't have this, 299, 276, 246. etc. If I drive my truck for 1 block each day and at the end of the month it will say 100% fully charged your estimated drive will be 139 miles. Uh NO. thats a calculation based on my driving history, I don't care about that. I want a baseline so I know how far my charge will go. I thought my baseline would be 299 miles but I'm not sure.

I know about energy, fusion, kool-aid in your tank etc. I know about variables about driving in the city vs highway, rain, cold, trailer etc. But I am trying to get a baseline of what a 100% charge on a 131Kw battery pack should give me, EPA mileage says 300 and I KNOW thats not true but......

Print, Cut, Paste over your Guess-O-Meter. Problem solved.

The reality of the situation is Ford has developed a method for displaying Range that they believe is best for the majority. You have already concluded you do not like it and that is your personal preference.

I personally dont like it either, I wish it only showed kWh remaining. Not SOC%. Not projected miles.

I also understand, Im in a nerdy minority and know its not likely I will get my preference of display, so I deal with it and enjoy my wonderful truck!

For the life of me I cannot understand why you want such a seemingly (to me) useless number. But if you must then I will say that I have not seen anyone in any forum claim that range is reduced by more than half for any conditions other than towing. So just assume you are going to get 50% of the EPA tested "mileage", or 1.2 mi/kWh and with the magic math your baseline resides at (1.2m/kWh * 131 kWh) =157.2 m. There ya go, there's your baseline. Anything better is gravy!


Note: I am mighty impressed that this site performed that calc automatically for me when I typed the "=" sign. Some AI lurking back there?

If you drive mostly slow in rush hour traffic, you will likely get a lot more than 300

How long will that take?

You may have it.

The only thing I can figure out is this guy wants a "i can go at least this far" number.

The estimate of remaining range is only as good as the data provided to the vehicle. If you just want the same range at a given remaining battery %, then take your favorite 100% range (320, 300, 270, whatever) and multiply be the % remaining.

If you want to know how far the truck calculates you can go with the energy remaining in the battery, then you'll need to understand why and how it uses the data it uses.

In this example of highway driving, I started at 100% battery and cold soaked at about 32 ⁰F.

On one hand, after driving 217 miles, the truck estimated that I had another 102 miles of range, which would be 319 miles, almost spot on to the EPA estimate for my truck.

On the other hand, the miles/kWh efficiency calculated and shown on the screen (2.5 miles/kWh) suggested that I should have had a total range of 328 miles, so I should have a range of 111 more miles. Not a huge difference and nothing to worry about.

On the gripping hand, the remaining battery state of charge (37%) means I used 63% to go 217.3 miles, so that calculation would suggest I should have had a range of 345 miles at 100% (217.3÷0.63 = 345) and should have 345-217 = 128 miles of remaining range.

Which is correct? I'm my case it's the 100 miles or so distance to empty. Ford blends--via a weighted average--multiple long-term and short-term inputs to determine their best estimate of distance to empty. If my long-term behavior is to use a lot of HVAC, but I didn't use much in the last 50 miles, it might assume that I'll use more for the rest of my driving. If my long-term average speed is high, but I recently have only been driving at 45 mph (say because of construction), then the estimated distance to empty night be lower than the unusual 45 mph might suggest.

If you don't want that, I suppose you can reset your driving history every time you recharge so the vehicle starts over and uses the basic estimate instead of learning about your particular driving patterns.
