Do i have the wrong battery??

[Motomax]

Yeah, 212 would be incredible. I’m down to about 100 miles per full charge in 30 degree weather. And yes, this is confirmed mileage, not just the GOM, and I only average about 1.4 miles per kWh in 30 degree weather. For me, the GOM is pretty accurate in both hot and cold weather. Average is about 3.3 in warm weather and 200+ miles. Cold weather sucks.

Have you tried not setting the heater to 90°? Haha seriously though, I’d expect that kind of drop from the -30° guys not from barely freezing…

How on earth are you averaging 1.4 miles/kWh?! Are you driving your car like you stole it with the heat at 80 degrees? On my ER RWD, the worst I do at highway speeds in cold weather is 2 mi/kWh, and that's driving near 80 mph.

I can get this bad if it’s cold and I don’t precondition.

Ha, I wish. In the warm weather, it’s fine. Somewhere around the 60 degree mark and I can get back to at least 3.0 but usually higher than that. The thing about the cold is that preconditioning is absolutely critical. Most of my drives are 6 miles or less and I don’t precondition. I don’t do anything crazy with the temp but I want it to be warm, yeah. The car uses all the energy trying to warm both the cabin and the battery but I’m already done with my trip by then. Plus I usually remote start and let the car warm up for about 5 mins before driving, which is something that I think would be pretty normal for most people in cold weather. So combine all that with the fact that I don’t precondition because I don’t keep my car plugged in and it’s about that’s what happens in cold weather.

In short, I’m basically doing everything wrong to get the most range in the cold, but nothing I’m doing is extreme or unusual. I’m basically treating an EV like an ICE and, well, that’s what happens. But lemme tell ya, the e-heat, the heated seats, and the heated steering wheel get that thing warm quick! And not only that, the heated steering wheel is legitimately heated, unlike many others (Toyota, Subaru, especially). An ICE can’t even remotely compare to the Mach-E’s heating ability. As battery tech improves, preconditioning will hopefully be less of an issue.

The site admin should really ad a pop-up window when someone new registers between the months of October and April that explains how cold affects EV range.

Hello, it looks like you are new and might be complaining about your cold-weather range decrease without having referenced the numerous threads on this subject. Due to high volume of questions, this is a pre-written response to help alleviate your concerns. Remember to use the search function before creating a new thread, as forum members are fatigued with new users asking this same question over and over again almost daily.

TL;DR - Range decreases due to cold weather, the range display is a highly pessimistic guess not to be taken literally, and you might update your software if you want to see a higher number.

First, understand that some range loss in cold weather is normal due to the laws of physics. Chemical reactions in the battery are more sluggish, the air is more dense to push through causing more drag, and your heater takes more electricity to run than A/C. The colder it is, the less your range will be because of these factors.

Second, know that the range you see on your display is just a guess. It can be off 40% or more from reality on some software versions. Do not take the number literally or you will be upset, nothing is wrong with your car. Unlike other brands like Tesla, Ford has made the reading extremely conservative and sensitive to cold temperatures on purpose, so that you don’t strand yourself in cold weather. Expect a sharp decrease in the reading below about 50ºF/10ºC that is greater than reality.

Third, be aware that software updates have been released that increase the accuracy of the range display in cold weather significantly. If you haven’t had software updates done at your dealer yet, you should consider doing so because you are missing out on a lot of improvements (CSP 21P22 released Nov 22, 2021). After the update, you may see up to 30% more range displayed even though your actual range is unchanged.

You can calculate your actual range yourself by simply noting the battery percentage before and after a trip greater than 20 miles. For example, if a 25 mile trip took 12% battery, 25/.12 = 208 mile range at full charge. Another method is to multiply your mi/kWh efficiency by your battery capacity, either 88 kWh for extended range or 68 kWh for standard range. For example, if you are getting 2.6 mi/kWh in an extended range, 2.6*88 = 229 miles of range. Please note that in cold weather, the actual capacity of the pack will temporarily decrease some, so 80/62 kWh may be a better capacity figure to use for an estimate in cold weather. Full capacity will return next summer with warmer temps.

The amount of actual range loss may vary due to many factors, but to provide a generic reference, a loss of 35% at 20ºF/-7ºC would be typical in average driving. This would equate to a range of approximately 176 mi / 137 mi for extended/standard packs. The percentage range drop compared to summer is also inversely proportional to the speed you drive due to the heater’s percentage of total energy use. If you drive in a city you may see a 40% drop in range, vs. a 25% drop driving on the interstate.

In summary, remember the range display is always a pessimistic guess, and your actual range will be greater than indicated. Remember to get those dealer updates done to increase your satisfaction. Parking in a garage, plugging in, and using departure times will help keep the battery warm and increase your actual range. Enjoy driving your electric car after gaining an understanding of normal cold weather range loss and the pessimistic guessing of the range display, affectionally called the GOM (Guess-O-Meter).

Your battery is bad you need to take it to the dealership and get it fixed ??

I don't ever precondition because I park in a parking garage with no charging ability (it is usually 10-20F above ambient, though). But for short drives I don't turn on any climate, so I suppose that helps tremendously.

 

[macchiaz-o]

My GOM indicates 238 miles to empty. It's a rough life indeed!*

* standard range, 70 degrees colder than July ?

Same here. For the first 5-6 miles, anyway. After that, it begins to improve.

Me too!

I smell a recall coming

Yours truly,

[Mach1E]

? right! He’s doing pretty good compared to everyone else that got the wrong battery.

He’s lucky.

I could charge the battery all day in my last car and it wouldn’t go anywhere until I put explosive dinosaur juice in it!

 

[OON7]

Nevermind... found some other posts gonna sit over here and read for a bit...

You did really good to catch on quick. Most people argue and tell everyone they are wrong and it is just their car is defective.

Welcome to the party! Hope you enjoy the car, range drop or not, this car is a ton of fun to drive!

Recently received my MME. Ordered a Premium AWD Extended Range. Window sticker shows the 270 range with the charge for the extended battery but when i got it fully charged for the first time today, (Dealership did not fully charge it) the Range shows 212 @ 100%. I have had the car for less than 2 weeks now.

Could my driving history and weather really be driving the range that far down? I have put 300miles on it, but don't drive every day. Live in Denver, weather has been between 20 at a low and about 60 at a high in the past 2 weeks. No new tires or anything like that yet either.

It's a fair question and sorry if you didn't hear about reduced winter range before making your purchase decision, but the great news is that you made the same smart decision of getting the extended range option as everyone who is familiar with winter range reduction. Do your best to boost the range by setting up battery preconditioning time for all of your regularly scheduled departures and also preconditioning the cabin for about five minutes from your phone app before you leave while the charge cord is still plugged in. If it is not too bothersome, wear a coat and use the steering wheel and seat heaters more and the cabin heater less.

@TeddySquared
Welcome to THE MachE forum. Where we are not only the premier site for honest information about your new Mustang Mach-E but also the premier site for smart-asses (myself included).
Since your busy reading through the old posts you found about range drop in cold weather (which btw, if you could do a DIY video on how to use the search function… maybe some screen cap video with dramatic narration… that would be great. It’s the one DIY video @Benjamin Kegele hasn’t done yet.) but… where was I.
Oh yeah, since you’ve already found what you needed, I’ll just add, at least it isn’t -20°F where you’re at. Here’s my wife’s car today.

That is also an extended range AWD with an EPA rating of 270 miles, currently showing a calculated 100% at 120 miles. I guess the EPA is in San Diego or maybe further south.
On a positive note, in real temps, the ones with at least one digit on the positive side of Zero, the real range, not the pessimistic dash display, is around 180 miles.
So cheer up, your GOM of 212 is a thing of beauty. It could always be worse.
Cheers ?
