Range estimate immediately after resetting

[MarkWill]

There is no problem. Warm up the battery pack to 75ºF, charge it to 100%, then reset the range figure. You'll be happier. Ford made the GOM to show essentially full EPA range at 100% to satisfy your type. The displayed state of charge is not the actual state of charge, so when it displays 80% you could be some amount less than that which varies depending on the hysteresis algorithm.

I am not entirely sure what you mean by "my type" but I will let that go I think you are misreading my own questions to imply I am generally worried about range. I am not.

I have another EV (got it the same week as my Mach-E) and across the same terrain,. same weather conditions and to a large extent the same type of driving, the estimates I get are entirely in line with what I'd expect that car. I can very easily get well higher than the EPA (and generally do, by quite some margin).

I have no questions at all about that car. It all just seems "normal" and expected - even for my type

But with my Mach-E, the highest we've ever seen at 80% is around 210 and after a reset and no driving, it is under 200. I will charge to 100% when I am back with the car and see what I get there.

Yes, I'll express some surprise that a newly refreshed car will show a range of around 50 miles less than the EPA figure, with only a temperature of 60+ degrees to explain that. But I'll keep my eye on this and see what happens.

Thank you for your comments.

I posted a similar question in a Facebook group but I was overwhelmed with responses educating me about range (how I drive, temperatures, it's just an estimate, etc). My question is NOT about range specifically - it's about the impact of a reset on the range estimate.

So let me narrow this down to a very specific question.

If I have an Extended Range AWD Mach-E and I reset my trip history (i.e. there is no driving history) and I have an 80% charge what would you expect the range estimate to be?

To reiterate, this is not a question about how to increase range, how the number presented is just a guess or any of that. I am asking about how the car would determine the figure to display IMMEDIATELY after a reset ( therefore with no history) and with the car not having yet been driven a mile, since the reset.

Why don’t you just do the reset yourself and report back?

Thank you for your comments.

The "my type" refers to the hundreds of people that expect the range to be an EPA number, which it won't be, because of the reasons given. The same people that then drive 25mph and take pictures of their "range" showing over the EPA number, then complain in November or February at the "brutal hit" they're seeing.

It seems you may not be that type, which is good. You seemed to start leaning that way when you said some have told you that the wrong battery was installed (yes, dozens of those posts too)...

The vehicle temp sensor doesn't react until you start driving, so if it's sitting in a 50 degree garage and it's 80 outside, it's 50.

Put in a destination and start driving and you will see a more realistic estimate. Then, drive faster than the speed limit and you can post (I'm joking here) that you didn't get that range, because the car didn't know you'd be driving 80mph instead of 65mph (yes, we have those posts too).

Last note - charge to 90% every night as Ford recommends, or do 80% if you prefer, but there's no reason not to do 90%.

I reset mine only a few time as I found it a pointless exercise because it soon reverts to real-world range according to ambient temp my driving style and all I’m sure you’ve already been inundated with.

Following a reset I found it to read around 379, one time below and another 384 at 100% charge as I seem to remember.

Mine is ER RWD June ‘21 Premium with stated range of “up to 379 miles”.

Does that help?

379 miles? My 2024 Premium AWD extended range says on the window sticker 300 miles of range; in charging to 100%, it’s never shown higher than 288.
What gives?
I will say this- the car has surprisingly good regenerative braking with one-pedal driving, but 379 miles?

estimates

Stop worrying about estimates and drive it. You're going to worry yourself to death. Monitor your miles per kilowatt and invest in a scan tool to read the raw data if you are that concerned with it.

Was the 379 miles stated on your window sticker? Maybe your electricity has more energy than what we have, but I have never heard of a Mach E with a range of 379 miles.

Correct - I am not that "type" at all I am not a "range chaser" in any way, although it's been difficult to explain what I am asking here. In fact, I just had another such poster say the same thing - " Stop worrying about estimates and drive it. You're going to worry yourself to death." Sigh....

So, let me have another go at explaining why (and what) i am asking.

I have two new EVs. I greatly enjoy them. I understand and accept that true range (the ACTUAL distance the car might be capable of driving) is subject to many, many variables and there's no "target". These include driving habits, temperatures, terrain and no doubt many more things.

I also understand that the range DISPLAYED is merely a guess. And that guess may be "less-than-accurate".

I get all this, understand it and - for these reasons - have never worried about range too much, aside from a curiosity and a driving style that tends to get good range.

With my other car everything is as I would expect. With my pragmatic perspective, sometimes I get good range and other times it is not soo good. But it doesn't bother me, it all all makes sense and I just love driving that car and don't worry about range.

But....

With my Mach-E the range (both actual and estimate) is considerably below what I might expect. Obviously it's a different car so the NUMBERS are different (lower for the Mach-E) so i am not expecting the same. However, many of the conditions (terrain, temperatures and - to a large extent - driving patterns) are the same. But with my other car I can almost choose to get well beyond EPA figures, just by driving better. With my Mach-E it's ALWAYS far below the EPA figure*.

So, what do I do? I can shout from the rooftops about how my car sucks. But I am not that type (seriously). That's a meaningless and pointless debate.

But what I CAN do is investigate and remove as many of the variables as I can. And my thinking was that when I reset I would at least remove the driving history from the equation. My plan was to reset and then very carefully log and track numbers thereafter, to see if I actually have a problem.

But the reset number was immediately much lower than I expected (290 * 80% = 232, seeing 193 instead). So, I thought I'd ask about that.

So, before I move on to logging, scanning, etc I wanted to verify how the reset worked - how did it arrive at that figure? Some people have misinterpreted that as me stressing about range, which is not the case at all. I am merely trying to understand what resetting does.

You have made the point that ambient temperature will have a very significant impact on that INITIAL estimate. While I remain surprised that a mild temperate (near 60) can have THAT much impact, it may well be the explanation. I will look some more at this and hope that it explains this.

I hope that clarifies.

* Just as a completely random comparison, after a 60 mile round trip in very "range friendly" conditions, my Mach-E is showing a range of 130 miles (from an 80% charge). This is in the same terrain, conditions and driving where I can VERY easily exceed EPA figures with my other car (and almost always do). The "underwhelming" range on the Mach-E has been that way since we first got it, hence my desire to investigate.

Put in the destination. Start driving, range will adjust for that destination along that route with those weather conditions. Then, if you drive the speed limit on that route, you SHOULD end up close.

Had a Mach-E for 3.5 years, a Lightning for 1.5. Mach-E I get 2.9 at best on the highway, driving 73 to 75. BUT, in our travels, across a total of 25 states and 1 province, have I seen markedly different numbers? Yes. I use 2.7 to plan my trips in the summer, and 2.3 in the winter. Hit a headwind (20mph) and saw 2.1 in the fall a year back.

Learn your normal miles per kilowatt hour on your highway driving, take off a bit, and that's what I plan with (hence the 2.7).

I also find invaluable having CarScanner open on a long trip so I can see the ENERGY, i.e. actual available kWh. Then I can look at my current efficiency and multiply in my head and that's my range. I also have an instant m/kWh in my CarScanner window and if I'm cruising, that's of interest (but it goes up and down a lot).

On a trip on New Year's Eve, awful weather, blowing snow, we started losing efficiency and couldn't make it home. Pulled into a nearly new Pilot / Flying J station just as their nationwide network went down... Nearest charger was an exit away. Car was at 5% (found the thread, tweaked numbers) and showing like 8 miles and I needed 12. But I knew my exact available kWh left (7.7). Did the math and said "if I drive 40 or less with my hazards on, I can make it". And, I did. I arrived with 1% showing, 3.XkWh left.

That’s what they are/were advertised at, thinks it’s because our electrons are lazier and get used up slower, or we’re allowed to be lied to lot more here ?
