Hi....the most perfect for battery wellbeing is by all accounts 80% or even 70% yet the guarantee doesn't limit you so the differential is tiny and gradual. I think we tend to overthink it on this discussion. On the off chance that you follow as far as possible guidance, day by day implies anything between 50 - 90%. In the event that I charge past that to go on an outing I don't mull over it.
I think this is right, sometimes charging to max won’t be a big deal in the least. Also if you will keep the vehicle for only a few years before trading it in, it probably won’t matter how you do it.

But if you might plan to hang onto it for a decade plus, you should not be charging to 90%+, or I’d say probably even beyond 80% if we assume some of that buffer Ford builds in is at the bottom end of the battery.

Put differently, if you only use around 10-15% of your battery each day, you really shouldn’t be plugging it in at all if you come home with 72% battery.

Lithium-ion batteries are happiest neither very charged nor very depleted. Assuming you do not need the range, you will not be doing the battery any favors by charging it up to 100% or 90% every night. Let it move around 70%, 60%, 50%, 40%, and 30%.

Agreed. I have Marlin set to charge to 90% at home. However, I only plug in if there is a need to plug in. My general plan will probably be plug in if:
  • I need a full (90%) charge tomorrow
  • Battery is below 50%
  • I'm doing a big trip and will override the 90% to get a full charge (rare).

I have charged it to 100% well over 10 times. Please explain a bit further no schedule and charge 3 times to 100%? I should have spotted that 100% charge is OK the first 3 times in the manual as the first thing I did was set up a schedule since it came with only 50% SOC. Never thought about that requirement and looking for the fix as no advice is forth coming from my dealer and/or ford. It resets at every stage of the schedule for me right now but after 2 months I am willing to try anything.
I didn't set the charging times/level in the app, I did it through the car's settings in sync4. That may be why you're unsuccessful and others are successful.

As a software developer of 35 years: it is clear that the Fordpass app is badly designed and written, or the backend systems feeding it are.

In the app, go to :
Vehicle > Charge Times > (Pick a location - you must have a location saved, such as home) > Use Preferred charge settings

On this screen, you can use a slider to set the max charge level anywhere from 50% to 100%.
Thanks for the tip. Did it as u suggested. set it to charge to 80%. It worked like a charm!

More likely both!

I charged the first 3 times to 100% then been charging to 90% as ford says. No problems

Would not of guessed no response ........... works for you does it? Home charging not working for some others on this forum. The one line is not a whole bunch to go on. Possibly some obscure procedure and if the crow lands on the west side of the barn roof in the morning it is going to work. From what I understand fords software needs time to gel ?. Sort of like by definition expecting a different result which is what I have been doing for close to 2 solid months. Give us something new to try. Dealer with Ford couldn't get it to work but maybe they didn't have the right info?
Don’t know what to tell you.
I’ve had no issues since day 1 and it works for me. Good luck
Glad to hear all your hardware is working for you. Not so for some of us and legit complaint when it is about the basic functionality of maintenance. What is the best charge I guess that would be fords default of 100% as that is all my software provides to me.

Dude I understand car => settings => charging and the simple sync operating system? You do not think it has been set on an iphone, android and directly on sync over the last 2 month? It has been master reset and doesn't work at my service centre with Ford involvement? Don't work dude hasn't for 2 months. Can't image Ford trying to say it is something a user did as to why their software does not work or they are slow finding the fix due to that owner but it could happen ;)

For us that do not keep our vehicles for just a few years and want to maintain our notable investment, not currently possible on my MME, I would think cold weather charging should go something like this.

I want it to be able to charge off peak. (not working)
Winter Procedure Required.
Charge to 80 - 90% (not working)
Remote start charging 1 hour +/- prior to leaving (not working)
Remote start 15 minutes prior to leaving. (working with workaround hit once errors out hit again fast and will work 9 out of 10)

Wish ford would get their software working for the basic maintenance of an EV getting grumpy and want it fixed.

The statement I put was not at anyone or to answer any question. Just what I do. But since you liked to call out like I didn't do anything for you. #nomanleftbehind. I made a video to show you.

Hope this explains it better for you buddy. cheerio.

dude instead of saying “not working” post exactly the steps you follow and maybe screenshots...if you want help that is.
If you just wanna rant then I don’t know.

also when you set your charge to 90% then the car treats 90% as your new 100% and will say “time to charge to 100% is Xh” but it’s really only charging to 90% then it will notify you “car is 100% charged” (to 90%).

I’ve tried both setup on my phone and the car itself and although clunky and not very intuitive, it works.

Na not worth it every one in the know has read enough and not commented. I have been building and installing computers since p100 and you can take my, my service department and fords word that it does not. When you have ran a network for 30 years the user end of the process is understood. I know how to deal with hardware, software and workarounds. I also have the logic to know when there is not workaround. Read a bit may help.

Maybe tell me what I should do for a workaround and I can tell you I tried it or not. 100% is always 100% here? Range kind of tells you that.

Great to hear yours is working ? imagine if it did not.

Ah, now I understand. Thanks for the clarification. I now understand that it will never be necessary for me to ever offer suggestions or any assistance to you in the future.

Please accept my apologies for not fully researching every one of your posts to understand why it doesn't work for you when it does work for so many others, and for wasting your time with my drivel. I can assure you I am taking the necessary steps to ensure it never happens again.

Wonder if it is good for PR to have known Ford affiliates (employees) with such manners? Me I find it a bit old and disgusting. But then it gets a few laughs.

I just went in to try this since I haven't been able to figure out how to change charge % and the latest version of Ford Pass app on my Galaxy S21 now completely crashes every single time I try to go into the Charge Settings ?‍♂. Why they didn't put the ability to do this in the infotainment is beyond me. My Bolt can get to this setting on the infotainment screen in 1 tap and there's a nice easy slider right there on the screen. Come on, Ford!
