Where's my range Ford?

[Maquis]

I'll keep testing in different ways but I've only been able to pull out 66 kwh from 100% to 0%.

Rated capacity is at some reference temperature, usually 25C. Actual capacity will drop off below rated temp.

Are you not capable of driving a few miles at both speeds and doing some mental asthmatic?

Nope. Never been capable of mental asthmatic. I prefer to keep my asthma well within the pulmonary system. But let me go check the drug cabinet and see if I have anything on hand for mental asthma.

And the drive from 100% to 0% would give a larger sample than simply a few miles at each speed with asthma used to extrapolate. Especially when performed by the same person… when that same person isn’t me.

I have posted my own extrapolations at different speeds in the past but I don’t have the same car as OP. So please forgive me if I mental curio-city has offended your pulmonary system.

Very lively thread! My car is still being delivered by dog sled somewhere between Alaska and the lower 48 so I have no experience to offer. I will say, based on what I have read, that either your driving is flawed or your car is. Many posters get an average of 3 mi/kWh or greater in conditions such as you state. So it’s obvious to me it is not about your battery size affecting range. Maybe figure out what may be causing you the low average mi/kWh. And please pass the popcorn and inhaler as I enjoy reading further posts!

Yep you're correct, I no longer think I'm missing kilowatt hours. After some arguing and name calling we found those missing kilowatt hours at the bottom below zero% ? now we're just trying to figure out why my efficiency is so bad. Either I'm a liar about how fast drive or how much my tires are inflated or it's Oklahoma's stupid wind I'm leaning towards the wind because my mama didn't raise me a liar ?

So I purchased a 2022 Mustang Mustang Mach-E RWD STD battery. It's supposed to have 70 kWh usable and 247 MI of range. Well at 100% the GOM only displays 191 miles which is actually extremely accurate because I did a full to empty range test and I got 192 miles. Before somebody says it's cold it was 95 today and the last 2 weeks has been 70s and 80s. I have OBD scan tools for the rest of this information, it seems Ford hides 5% at the top and 5% at the bottom which it's not abnormal. Other car companies also have buffers at the top or the bottom. The bone I want to pick is the 70 kWh usable figure. When the car shows 0% and 0 miles the OBD says there's 3.3 kWh still in the battery. So that's basically unusable bottom buffer. That's fine not that strange but when I charge the car up to 100% it shows 69.28. so that would mean subtract 3.3 from 69.2 that = 65.9 usable? Am I missing something here or do I have a legitimate concern? Maybe one of my modules is damaged? The OBD reader does say my battery state of health is 100% I would just like some other opinions on this maybe someone from Ford.

I will admit, I do not think I have seen anyone on this thread get what Ford advertised. Always for one reason or another but my car is rated for 260....best I have been able to get at 100% is 210....its best to just ignore whatever Ford advertises because it will always have caveats to it that make it close to impossible to get what they advertise.

My wife (AWD EX) will get EPA milage in the summer (that two week period where it’s 80° or more). I, with slightly more aggressive driving habits, will not. During the rest of the year (the three seasons of pre winter, winter, and still winter) even she won’t come close to EPA milage.
Several others have posted that the can match or even beat EPA milage. But I’m not sure I could ride with them and stay awake.

In the summer with reasonable driving habits, I can easily exceed the advertised EPA range. Many others have reported this as well. If not in this thread, definitely in this forum.
Summertime city driving I average between 3.5 & 4.2 M/kWh. I only need 3.1 to achieve rated range.

It'll be interesting to see if it improves but temperatures around here have been pretty mild I'm in the south and it's been 60 to 80 last couple weeks. My math says the EPA number should be around 3.3 so we'll see if I get that or not in a few months.

I believe RWD needs 3.3 and AWD needs 3.1 miles/kwh to hit EPA. I’m more a 2.7 kinda guy in the summer and 1.8 guy in the winter.

Rated capacity is at some reference temperature, usually 25C. Actual capacity will drop off below rated temp.

I had read that as well and I am not sure 25C is the correct temp.

Here are some readings taken at 100% displayed on different days over the past several weeks.
HVB temp and Estimated kWh to empty

• 17C 84.144
• 21C 85.570
• 22C 86.052
• 24C 86.298
• 24C 86.506
• 25C 86.448
• 25C 86.972
• 28C 87.556

My car is supposed to have 88 kWh usable. I have yet to see that figure. Knowing Ford the way I do, then that last figure at 28C would qualify because Ford would round up and call it 88 kWh.

I suspect you’re correct. 25C is normally used by battery manufacturers and labs. The equipment manufacturer can use whatever they choose.

Nice logging! I don't drive enough miles to charge to 100 that often. But every time I do from now on I'll be sure to note the temperature! I did glance at the temperature numbers yesterday but I honestly don't remember I didn't screenshot it.

I know im late to this party. But to do an good range test you need to do a 100% charge go on highway 70mph go until about 50% left or little over then turn around same route go back and then as you are at 5% you should be getting close to starting point then just drive around that parking lot for the next 20 minutes or so until when you pull up to the charger it will no longer have a charge that extra might be where you are missing out.

However, with your stated 2.3kw *70 does equal what you were saying at the beginning so you are not losing any range. Remember the 239 or whatever are just estimates of the range in ideal scenarios. If you said is true that it was 95 degrees when you did this test guess what the car was using more juice to keep the batteries cool so their goes some of your ele ctrons.

How is driving around for 20 minutes in a parking lot useful? When I do it and I've been doing it for years the same way so my findings can be compared with each other as accurate as possible in the real world. The whole test is at 70mph in a 44 mile loop around and back as many times as I need to, except for one mile at the beginning and one mile at the end I'm at 45 mph only because I have a speed limit between my house and the highway. I end at my house as close to 0% as possible

Maybe a fake supercharger will help with the asthma
