Miles at 90%? Battery degradation?

no way! any idea why?

So, how many miles it provides at full charge is impacted by weather and driving habits?

Also topography. Going downhill will increase it. Going uphill, will decrease it.

I have an extended battery model that has 5K miles. When I first bought it, at a 90% charge it estimated mileage at 270. Now at 90% charge it only estimates 257 miles. Is this loss normal?

Measure battery wear with an obd2 dongle and a phone app like car scanner. There is a stat 'hvb soh' (high voltage state of health'.

As others point out, the range estimation in not appropriate.

Sigh, another GOM thread, almost as many of these as the NACS adapter threads....

Yes another range loss thread……but let’s cut the poster some slack since they are new and welcome here. I’ll add that sometimes this app or the website is very wonky and the search function isn’t great. I’ve found when my internet speed is slow, it’s Really hard to search out a simple question. So I ask one instead. And like any newbie, I struggled to format my question in the most sensible way. Heck….I’m still struggling since both mechanical and electrical knowledge are way down the list on my skills list. But thankfully so many posters always come to the rescue!

Always charging to 100% will degrade your HVB compared to charging it to 90% unless you're headed out on a road trip. Hence Ford's recommendation of 90%.

Since my recent experience with Ford service for a TSB repair, I am not looking to keep the car past the 3yr / 36 month bumper to bumper warranty.

I don't have the stomach for the hefty repair bills and weeks left without use of my car.

So I don't care about the battery degradation.

100% all the time now at Tesla Superchargers.

I'll pick up another for 3 years - rinse - repeat.

Make sure you tell the next owner of your charging practices.
Seems kind of like an ice owner that changes the oil every 20,000 miles.

That brings up an interesting point... it's all data history that it seems like the car should have stored somewhere. Be nice if the manufacturers provided an easy way to access it, and consolidate it into a nice summary report.

You need to reset your Guess o Meter it derives mileage based on your driving habits whether

OK, thanks. I didnt realize that. I assumed that the charge range was a constant and not variable, like how many miles you actually get is variable.

EVERYTHING about the Stang is variable ?

I call it STS - shopping trolley syndrome!

Does what it does when it wants, goes where it goes where it wants and how it damn well likes.

No two journeys are the same no two applications of any function are the same.

It’s like the randomiser of motoring experiences.

God, I bloody love this car?

 

[Teslaeata]

My guess o meter has never failed me.

Since turning 60 I need so many tea & pee stops I throw it on charge whenever I stop on a day out.

Think the charge socket’s wearing out faster than the tyres ?

Reset your driver data.

Get your estimated range back.

An ICE GOM vs an EV GOM are not apples to apples. ICE are not affected as much by weather and pretty much track JUST driving habits. When the GOM changes dramatically in an ICE something could be wrong with the vehicle. People new to EVs should not be shamed for assuming things could be wrong with their vehicle, it will just turn them off from the community and from EVs. Especially with all the FUD people spew about EV batteries being awful.

Yep, the mocking of newbies asking about range has always been a turn-off. Makes the forum come off as a clique of Mean Girls.

Regarding ICE GOMs, it depends. I think you're correct on many older vehicles. But I know some newer ones are similar ro the MME (calculate based on far more recent driving history, and possible other inputs). We also have a 2023 Bronco Sport. It's GOM varies even more than the MME does. Following a favorable recent stretch of driving, a full tank will show over 500 miles range. But following a less favorable stretch, a full tank will only show around 350. Even just driving for 30 minutes I can see it creep 100 miles either way, based on recent MPG.

Meanwhile the 2013 Escape it replaced was far less variable. It seemed to use a much longer time horizon as it's avg MPG basis for the range calculation.

I'm not talking how many miles I actually get after its charged and I start driving. I realize that highway driving and fast accelerations and cold temps impact the actual miles it will provide.

I'm talking about its range at charge. It should still estimate 270 miles once I unplug it even if it does not provide that due to driving conditions.

The GOM has a memory. It doesn’t start fresh with every charge. I have a GT. Starting #s based on 100% charge have ranged from 256 (after 2 days of Interstste) to 312 after a week of in town stop and go. Both normalized to near 275.
