Extended Battery range

[tucsondivots]

Sort of. The recommendation is a little outdated and probably more applicable to an old model but we wont belabor that.

You are absolutely welcome to charge to 100% if you plan on driving soon and the trip should have the battery dip under 90% if you are super anal.

The not charging to 100% does not mean NOT to charge to 100% just done leave the car at 100% for a long time, that's bad, for a NMC battery.

Not from what I have read but I am a newbie so trying to learn?. Manual says Extended to 90% on regular basis but 100% occasionally ok . Standard to 100%.

I have a 2024 Rally, so same battery.

Adjusting for the difference in actual range I experience (240) and the EPA rating (265), and then scaling for your EPA value (300), yields an estimate that I would see about 270 miles of real world range in your car. Your 240 at 80% looks like a reduction of about 12%. The GOM is using the recent experience to calculate the estimate.

Terrain, climate, traffic, and driver will all impact experienced efficiency, but I think the value you see is within the very broad window of reasonable values.

The battery degrades faster at a higher voltage (100%), it's OK to charge it to 100% but don't leave it there.

The battery degrades if it charges very fast, but we don't charge fast.

The battery degrade if you fast charge at a cold temperature, but it usually heats it up to prevent that.

The battery degrades if it gets very hot, avoid this.

If you want to have it sit for the ER battery consider 85% vs 90% but it's really a small difference

Otherwise enjoy the car.

Hello I am new the forum. I purchesed my 2024 premiun Eawd about 2 months ago for my wife. My question is when I charge the battery to 80% what range should I see for a 91kwh battery. While the car is still in the garage I go to the Ford app I am only getting 190 miles. That does not seem correct?

Welcome to the forum Gambit. Surprised you’re not riding a Nissan Rogue. (Though perhaps I’m reading my own comic book inclinations into your choice of username).

Anyway, as I’m sure you’ve figured by now, the Guess-o-meter on the dash is doing its best to take current weather and your driving habits into account to give you an accurate estimate of your true range. The number the salesman quoted you, and what was on your window sticker, is the EPA ideal range. The ideal reflects the EPA driving tests which include warm weather, no headwinds, and an aerate speed of 48 MPH on the highway. So it’s really unrealistic to expect that at all… and especially in the winter.
I know, I know, there are other car manufacturers who program the dash to show the ideal number no matter what, but Ford is trying to be honest with us…. After inflating the number to initially get us. It’s like a gal that wears a lot of makeup to lure you in. And once you put a ring on it, the makeup goes away. She’s still pretty, but she’s not lying to you anymore.

Just making a joke. You know, at any point in time, 100% charge would give you more range than 90%, right?

Well, the temperature has gone from 85 to 72 in two days and I have not driven the car in two days and I’ve lost 10 miles just sitting in the driveway lol so temperature matters.?

The only reason I charge to 80 is because I don’t travel but the other reason is once it starts going over 80 it actually takes forever or longer to get to 90 or 100. So once it gets to 80 pretty much slows down, I believe the charging speed that is

Recommendation is to charge to 90% on NCM extended range battery.

Never mind. Seems like my comment went right over some heads. I’ll try to be more serious going forward, … maybe.

We are officially in the "I think they gave me the wrong battery" season. Your mileage may vary. Season's Greetings.

Not from what I have read but I am a newbie so trying to learn?. Manual says Extended to 90% on regular basis but 100% occasionally ok . Standard to 100%.

You're talking about the difference between the NMC-type lithium ion battery used in the ER and older SRs vs. the LFP battery used in the newer SRs. That's an issue for another thread (and there are several on this). The OP has an ER, so the NMC battery.

That’s only true for DC fast charging. You get full charging speed on L2 AC all the way up to about 97% SOC.

If you do some calculations (simple from what I remember, but I can't recreate them on the fly), and take the buffer in the high voltage battery into account, an actual 80% charge on the battery is ~87.5% displayed. I think the manual says 90% because it is 'close enough'; I personally only charge to 90% if it won't be at that level for long. Typically I only charge to 85% unless I *might* need the range in which case I don't blink at a 100%. Battery health isn't a reason to risk being stranded.

Edit: This is for the extended range battery. Generally, 80% is considered an ideal max charge for the ER battery. The standard range battery can be a different chemistry and can have different characteristics.
