Shouldn't my Display read 270 @100%

[dbsb3233]

why would we do that? these threads are popcorn on an otherwise dry and technical forum.

True, if people didn't want to reply, they wouldn't reply. (Even if it's just to complain about it being a repetitive thread. ?)

If you expect sincere responses maybe best not to come in and make comments like threatening a lawsuit because you don't understand how a range estimate works.

If it was a question and not an accusation, ask your question. Otherwise you show confidence in your ignorance and aren't going to be taken seriously. My two cents.

Well, first off, let's do some remedial education, I didn't make any threats, especially to the participants on this forum. Secondly, Scooby dumb, I understand how range works...however, admittedly, I may not fully understand all aspects of the range meters adaptive capabilities. Hard to believe you're actually from my hometown, we don't have many jerks there actually.

I think this has been answered a couple of times in this thread at least, but let me try in a slightly different way.

The charge percentage is the amount of charge in the battery (in the portion that Ford will let you access). Maybe you charge to 90% every day (Ford recommended) or to 100% or to 80%. That doesn’t matter.

When calculating the estimated range on the dash (what we call the GOM or “Guess-O-Meter” around here) , Ford gives you a number that’s a multiplier of your current charge level times your average driving efficiency, with other tweaks thrown in regarding the weather (cold temperatures act as a negative in this calculation). This happens all the time…driving…sitting on a charger…just in your garage unplugged…whatever. The calculations are constantly being updated in view of all of the variables at any given time. For example, my car has been sitting at the body shop for three weeks, and while the charge level has barely changed, the estimated range has been fluctuating wildly because we’ve had temperatures bouncing up and down around here like a kangaroo.

So, in the Fall with nice driving, your range at 100% might be displayed as 270. If it’s even nicer, you’ve done well on your driving efficiency, and you’re not driving a lot of high speed highways, you can see 270, 280, or even 303 on the screen of a model that is EPA ranged at 270. Some of the Route 1s see over 330 on their range estimators in ideal conditions. If you’re in the Alaskan wilderness in February, your guesstimated range on the display will probably look like 170.

Some people will say to reset the driving history to see the default, but if you reset it in the summer, you might see 270. You reset it now, you might see 220, all just depending on the cold.

One thing we all seem to agree upon here is that the GOM is overly pessimistic relating to winter temps. You’ll usually actually get more range than guesstimated. It’s definitely better that way than the other, however. Also, this usually isn’t a concern at all unless you’re driving close to the edge of your range every day or going on long trips. Most people don’t as a general daily rule…they leave the house, go to work, stop at the market, and come back home with plenty of range left, but they plug in, go to bed, and wake up every morning with a ”full tank,” ready to do it again. So for all the worry about range and range estimates, a lot of it really only comes into play if you’re an outlier on the amount you commute or if you’re continually taking road trips.

Thanks for the detailed response, greatly appreciate the time you took to outline this explanation.

Yet another take on the answer to your question:
Yes the dash should show 270 miles at 100% state of charge. But only if you follow the EPA test-driving guidelines:
1. Drive only indoors on a dyno in a climate controlled environment at 70-75° Fahrenheit with no winds.
2. drive 50% of your time in stop and go traffic mimicking stop lights and signs. For this half of your driving don’t exceed 40 MPH.
3. Drive the other 50% of your time at 55 MPH with no elevation changes.
Driving in an uncontrolled environment, faster than 55 MPH and not spending enough time doing stop and go will greatly effect your dash display. Also driving outside in different temps at different elevations will effect the dash display. Going fast (over 60MPH) and being cold (below 80°) are two things that will tax your battery the most and cause your dash displayed range to go down.

First, let me say I love my Ford Mach-E....I'm literally stopped in the street by pedestrians and drivers alike to admire the car! However, I'm in a battle with the Ford Service organization, because I bought the Extended Battery, and not once has it reached 270 miles on the range display. It says it's a 100% when it hits 213 miles. The highest it's every shown after several days of charging in a warm garage is 238. Service keeps talking about reduced range during the winter, which I totally understand...but why won't it reach 270, and why does it say 100% at 213 miles. Please help, this is extremely frustrating and I don't want to file suit, but I paid a lot for this car like all of us did, and I want every mile due to my long commute. Thank you

in addition to the numerous replies you’ve already received, just like a regular gas car’s EPA MPG on the sticker, it ALL DEPENDS on how you drive the car. If you are driving at 80mph your MPG will be less (ie less range) than if you are driving at 60MPH. And just like the regular gas cars there is a predefined “course” that gets driven, at precise temperatures, etc. if you don’t drive that exact predefined “course” you won’t get the MPGe. As I understand it the 270 range is based off a MPG(equivalent) which is established with approximately 60% of start stop city driving and 40% highway driving with speeds between 30mph and 60MPH, at a 70 degree temperature with ZERO USE of climate control systems.

all of this is WELL DOCUMENTED and you would never win a law suit. I suggest you learn to live with it, and enjoy the car, and wait for warmer weather and see your range to up.

Why is there a link to the "Lightening" forum if Ford is not involved here? If it is a general auto indurstry then I would imagine there would be non-ford links. Just a thought.

The same conglomerate that runs this forum, has a ton of other automotive forums that it also owns/operates. The lightning forums are just like this forum -- a third party site made to cater to fans and attract members so they can sell ads. But it is a convenient place for us all to gather, so I'll deal with the ads.

Both are completely separate from Ford and in no way associated with Ford.

Look at the log showing each charge. Divide the number of miles added by the percentage added. The quotient should give you an estimate of the capacity of the battery.It will be lower in the cold but I believe it is accurate. The range reported in the cabin considers your driving patterns and weight in your car.

As you can see from a recall note, it appears Ford knows this is an issue (at least for recalled Mach e's that need windshield and overhead moonview replaced. Note that they say "Ahead of future Ford Power-Up over the air software releases, we have authorized our dealers to perform several customer enhancements, including the following: improved range in cold weather, DC fast charging, range accuracy, etc.

I appreciate the sincere responses to my posts, and frankly, those of you that have been on here maybe too long, should take a deep breath and actually READ what people are saying before you snap off with a response. I've seen the tons of responses on "range"...which is NOT what I'm talking about....and as I said, I understand your range will be reduced in cold weather. As I said, my car is NOT being driven...it's only sitting on a charger. What would have actually helped me in this forum, is if anyone can confirm if there indicator reaches 270 on the display or not. Additionally, it would help to know if you have an extended battery that hits some range estimate like 213, when it normally gets to 270, but still reads 100%. Would ask that folks that are truly here to help newer owners respond vs the non-friendlies

I think the responses to your original post were fair. You didn’t give any indication that you had seen the numerous other threads on this topic, and on top of that, were talking about filing suit. The responses simply matched your original tone, nothing more nothing less.

I think you would have gotten a much more positive response if you wrote something like “I have seen the other threads about how the range indicator is an estimate and changes based on environmental conditions and driving history, but I think I have something else going on with my car because I am seeing XYZ, has anyone else seen this or can explain it?”

Of course I don’t think you could have posted that because you haven’t actually given any indication that what you are seeing is different from what lots and lots and lots and lots of others have previously started new threads on.

And yes, for some people, the range estimator has shown 270 miles of range, even well over 300 miles of range, but in the summer, not late December.

He's got to be a troll at this point right? Especially with the seemingly fleeting understanding of how the quote reply system works? Like he does it correctly then goes BACK to doing it wrong? How??

A couple of additional thoughts/perspective. Was your previous car a traditional gas powered ICE or hybrid? Did the car calculate MPG or range? Did you ever notice that estimated MPG and range diminished during the winter? I only say these because it is very typical and normal to see on ICE vehicles drop MPG by 15% or more in the winter. Hybrids are generally worse and you could expect to see drops of 25% or more. There are many, many sources for this if you search around the web. I personally experienced 20-25% drops in my previous car, a 2019 Honda Insight Hybrid, during Ohio winters.

Based on your post, you are seeing 213 instead of 270. That is a drop of 21.1% and is not really out of line for any vehicle type in cold conditions. Others have also noted there is a software update to tweak cold range estimates that may ease your concerns and further reduce this gap.

As many others pointed out the range meter is a guesstimate based on a lot of factors including temperature and driving style. The EPA range is an estimate based on a standard set of variables including temperature, driving style, elevation, etc. How and where you use your car is the biggest variable in determining your estimated range. At the end of the day everyone with an EV is going to see a reduction of range in cold weather. On the flipside, in ideal conditions many EV drivers may far exceed the estimated range based on their driving style. The calculation may be just as far off from the EPA estimate as in cold weather, but I doubt we would see people up in arms about getting too much range. (Except for one of these threads where someone complained the cold weather range dropped too far from their above and beyond range from the summer... can't please everyone!)

What I'm trying to convey is that this drop is not dissimilar to ICE vehicles. The range drop may feel more significant but it is in the ballpark of what everyone experiences in the cold weather. Also do not lose sight of the fact it is an estimate, unless you drive it to 0% you don't know how much actual range you had. You could also take the advice of many others to extrapolate your actual range from partial drives.

Enjoy your car, charge in a garage if you can, use preconditioning or remote start if you can while plugged in, consider your driving habits, your climate control, etc. if you are concerned about maximizing range in the winter. If taking trips, be a little more conservative on how far you go between charges and/or consider charging a little above what the trip planner recommends at each stop.

If you truly cannot accept the range drop, sell it or trade in. You will likely pull in a profit right now, especially if you receive the tax credit. A lawsuit is going to cost you more time and money than it is worth, cut your losses.

Lastly, if you intend to keep the car, charging to 100% normally is not advised for battery longevity/health. You may want to consider dropping to 90% or at minimum 95% unless you are planning to travel to the point you need 100% battery for the day. Good luck with the car, everyone is going to say a variation of the same thing and provide some hints to help you think about the range differently based on real world conditions. I'd wager that someone would have to post one of these threads where they lost at least 40%+ of range vs. the EPA estimate before it would truly cause a discussion about an actual issue.

I understand the reactions here and in the other related threads posted daily, but I also think it's fair to be disappointed by the GOM's reporting. I drove 138 miles at highway speeds using 50% of the battery at 1°C in snow on Christmas, but my GOM is completely detached from that reality. Extrapolating to 100%, it has and continues to estimate under 200 miles when I'm empirically seeing over 270.

Extrapolating to 100%, it has and continues to estimate under 200 miles when I'm empirically seeing over 270.

Agree that it's kinda of laughable how bad the GOM is at times. Mine showed 107 miles @ 64% (167 range) the other day. Sitting in the garage at 40F. That would be 1.9 MPK (mi/kWh). That's not even remotely close to my real range, even at 40F. Did a road trip 3-4 weeks ago at around 40F for most of it, and averaged 2.7. And that's at 75-80 MPH most of the way.

The real lesson here is to mostly ignore the GOM. It's close enough when you're doing a drive leg and are getting down below 30% (the error isn't is big then), and just wanna estimate your safety buffer between the remaining nav distance and your GOM. But that's about all the GOM is really good for. It's pretty worthless at higher SOC%.

 

[Zassi]

I’m propably poking a hornets nest here but am I really the only one here who thinks that the GOM is actually quite accurate? It usually starts a bit on the positive side for me(maybe 5% over from what I’m really gonna get out of it) but quite soon it adapts to maybe 5% less than what it will be in real life. It’s been like that from day one for me, and I’ve been driving it for 10000miles now in the past 4 months.
