Charging more than 80% regularly?

[OON7]

I charge to 95% at work for free and to 70% at home. Battery health is 99.5% after 16.5k miles.

Since the long term storage recommendation is 50%. Based on my average commute I charge daily to 70% so that when I get home the car sits at around 50% for the max amount of time until charging starts at midnight.

I was charing to 90%, but with a long commute it got annoying to charge so offten. I just go to 100% every time now. Not worried about the battery, many people do this and after 3 years or so have no degradation.

Hello everyone. Just got my 2023 space white Mach E GT AWD. I love it!! Just wondering if anybody is charging it more than 80% on the regular. Thanks.

I charge from 20 to 95% every 10 days

I drive the car for a few kilometers at a time, so mine is always at 60%. I believe that is the safest place for the car battery to be. The lowest I go is about 30%.

I got the car in January and I'm at 1,700 KM. That is slightly over 1,000 miles in over 6 months.

Got the same model and color that you have, an MME-GT in Space White except 2021 probably a second build. I always charge to 100% and have not seen any degradation thus far. In fact, this year on some hot days I've got as much as 305 miles of charge. I'm near DC.

Quick question: If the car is set to charge to 80 or 90% at your home location, and you want to charge to 100% before a trip, then do you have to manually go into the charge settings to change them each time you want to charge to 100% or go back to a lower charge? My understanding also is that changing those settings in the App is not reliable either. Thx

In the ford pass app under the charging settings there is a button : 'charge to 100%'. You can tap that and you do't have to change your charging presets. I hit it last week by mistake and the battery charged to 100%

You've gotten a lot of good replies - but know this:

Percentage is part/total. It's meaningless unless you know what either the part or the total is. 5% of 100,000 (5000) is much bigger than 50% of 100 (50).

In this case, Ford "saves" the top 10% of the battery's physical capacity, so assuming a 91kW battery, that means you never see the "top" 10% = 9.1kW. So your usable capacity is 91kW-9.1kW = 81.9kW. So, at 90% indicated on the GOM (Guess-O-Meter), you will really be at 81% (81.9kw *.9/91kW) of physical.

So charging to 90% indicated is really 81% actual.

I'm not sure the buffer should be considered in the charge percentage. I mean clearly ford is being extra cautious with a good sized buffer built in , but they still recommend for average use unless you need the mileage to charge to 90% ac charging.

The reserve is not all at the top.

I'm okay with it personally - because in a few years they can "unlock" that 9.1kW and viola - you get "extra" range.

60,000 miles in 2 years so have to charge to 100% twice to three times per week sometimes and battery seems to be holding up.

I only charge to 100% when I know I’m out on road following morning and if not out on road and really low charge the night before I go to 90%. C40% of my charging is on the road at public charge points and probably only half of those occasions do I go to 80%.

We have had our Mach E two years and almost 30K miles. Charge to 100% every single time.....about twice a week. No degradation noted in range. Still getting over 300 miles on GOM after charge. AWD ER Premium.

I came across this on YouTube suggesting keeping charge between 65%-75% to maximize battery life.
the article referred to in the video is https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries. For me charging to 70% has been more than adequate — except for when we prepare for a trip.

That video is based on cell phone batteries and I believe EV batteries would need different testing data since there are many differences between cell phone batteries and BEV batteries.
