Long term battery life

[sglewiswl]

The Mach-e is SOOOO much more fun though. I sold my Leaf and bought a Bolt in 2020, that was a great upgrade, same size, just much faster and much more range. Although now with a Bolt and Mach-e I only drive the Bolt if my wife has stolen the MME.

Oh the Mach-E is a better car in every way. The Leaf was great for a subcompact. EVs have so much torque the even little single motor cars like the Leaf are impressive..

2022 Premium RWD ER, 62K miles, 3.5 years old, SOH is currently sitting at 93.5% and has been there for the last year or so.

I’m sleepy rn so my mind is toast, but according to the AIs:

For max longevity,
Keep it within 30 to 70 (even 40 to 60) for max life, bump to 80 instead of fast charging, fast charge before it drops under 30 and try not to go too long or too high in a session.

Aim for around 50 if car sitting idle at work or in storage; a bit lower if in the summer heat

This goes for your phone as well

Most of that is nonsense, as is most AI stuff.

Ford designed the system to charge to 90%, which is basically 80% of the total battery.

50% is for 30 days or longer, not "at work".

Summer heat is irrelevant.

Ford suggested charging to 90 only for long trips, note they didn’t say 100. Ford technology is not able to overcome inherent limitations of lithium batteries. Why do you think they don’t say 100? Why do the new iphones have the ability to set 80% limits? Think

The hard reserve is well known and wise, otherwise owners might wreck their batteries in no time. Why do you think they even reserve any? Being that our 80% is not the “true” 80%, it just means it is closer to 50, which preserves battery even more long term

50% is for idle, lithium batteries degrade at high and low charges, especially high charge in the heat. Anyone who has abused their phone especially the hot running titanium iphone pros will see immediately. Obviously, in day to day your car is most idle at work

You are incorrect. 90% for daily driving.

Thanks

And I agree, AIs are bad for subjective, opinion stuff, as they reflect the content of their training data (so if it’s trained on reddit it’ll be a redditor), and the rails the designers built in

But for dry technical things they tend to be pretty good. Of course, they need to be prompted to “understand” the situation, and we know they can also make up things

No need for such a tone. The battery research around (which I trust more than Ford) says that it’s ideal to shallow cycle the battery and keep it close to 50% as long as you can. There is a difference long term between doing daily 90-70 and 60-40, but in the long run it won’t be a big number difference (single digit % difference, e.g. say 8% less degradation on a 20% degradation = roughly 1.5-2% or total 22% degradation being lazy instead of a very strict planner).

I’m gonna trust Ford because they’re the ones paying for very expensive battery replacements during the very generous warranty period.

I’d agree, like brake fluid and general maintenance, I’d always say defer to Manufacturer’s recommendations though I couldn’t always due to my needs running up 120,000 miles when out of necessity I charged when and how my needs required.

If I’m honest, I don’t believe there ever was a 100% SoH if I started monitoring when new!

I started monitoring SoH a few miles in, around 35,000, at probably around a year old, at around 95%.

Simply can’t believe it dropped to 95% in that mileage and short time and distance and only a further 1.5% over next 3yrs 4mths and

Interesting, and sort of confirms my suspicions that there was never actually a 100% SoH.

I wonder if anybody ever has got a 100% reading when new.

Mine did actually show 100% for several months. As I mentioned before, I had about 12,000 miles when mine first dropped, 97.5% (originally my post said 95, but I went back and looked.). It STILL shows 97.5 at 17,000 miles at 1 year and 9 months.

2022 Premium AWD ER, 53K miles, 3.75 years old, SOH is currently 95.4%
Normally charge on L2 to 80%. 100% several times per month for trips.

It has absolutely 0 problems making up dry technical “facts”, while providing you citations to papers that happen to not exist.

The AI chat bots first and foremost are tuned to tell you what response it thinks you want…you can generally get them to tell you anything.

Long range battery on mine. But it’s an early 2021 build with over 40,000 miles. Battery is above 95% last time I checked.

OK, you made me look.

MY2021, Job 1
Build date: 12/09/2020
Mileage: 57,000
Battery age: 58 months
Battery SOH: 92%

Interestingly, my 2022 Lightning has a 41 month battery age, 51,000 miles and also a 92% battery SOH.
