Has anyone evaluated the Ford advice that charging degrades your battery using a FC versus Level 2. Just my thought yes scrambling the battery molecules using FC but does it really hurt it with a lower level 2 charger?

It hurts it less with the Level 2 charger, but it's still extra stress on the battery to go to 100%.

This isn't Ford - discussed MANY MANY times - just research LiION batteries and charging. Its a very old topic.

Got it. First full on EV I've owned and going by what Ford recommended so don't have much experience with it.

Li batteries like to be at 50%, but that’s not ideal for daily use so 80-90 % is recommended. Charging to 100 does stress the battery a little bit more so if you don’t need the full capacity avoid it. A battery is going to lose capacity, even if you baby it, just faster if it is stressed more.

DC charging (fast charging) stresses the battery even more.

Or charge the crap out of the battery and get a replacement before the warranty expires.

I was thinking 80 to 90 is 10% charge and doing that 5 times is not different than going to from 30 to 80% one time.

But you say don't charge every night just to get from even 70 to 80, but let the battery get to...30% then charge it up to...80% unless I need the range?

(GDN - I would do research, but I am lazy. And since Leaf has done the research and I am in this conversation, I assume you can just scroll past.)

Yes, if you know that’s what you need then you can save a few cycles, but I would have to say that’s very minimal gains in the end. Tesla has the most data out there, their batteries tend to lose about 5% by 50,000 miles and about another 2% the next 50,000. (About 7% over 100,000 miles.) Babying it might save you a little but I doubt anything significant. But if you are in the cold (under 50), then charging it nightly would outweigh skipping charges. Without preconditioning the battery is stressed while warming back up to optimal temp. In the winter I keep it plugged in nightly, in the summer I don’t.

Like another poster said, enjoy your truck. Yes certain things aren’t great for it, limit if possible. if you can’t then your battery might lose more capacity at the 100k or 8 year mark. If it loses too much then Ford will replace it.
