New to Mach-E and EV in general

[Marcin]

Limiting NCM battery charging to 80% allows you to enjoy high SOH for longer. If you don't need long ranges on a daily basis, this type of charging has many advantages. My observations show that LG NCM batteries are very durable. I work in a car repair shop, but in Europe, I often deal with Mach-e vehicles. I even keep a small SOH statistic for batteries. They typically have SOH above 95% by 30,000 miles, and above 90% by 100,000 miles. I'm also currently working on an app for checking HV battery health in Mach-e vehicles. Currently, it's available for Android. If there's significant interest, I'll implement additional features and iOS versions and try to adapt to US standards.

The first version is officially available on Google Play:

Initial version look cool. I will give a try once I buy those mentioned devices.

Hey Marcin
I've owned my 24 NCM for a year, and for some reason, I chose 85% as my default charge amount.
Should I lower it to 80 because that extra 5 percent is harmful?
Probably not, right?

According to Form, the NMC battery can be charged on a regular basis to 90%, so I don't think you have any worries about battery degradation if you have been using 85,% as your regular charging ceiling.

Stangy’s 5 yrs old next week.

Just passed its annual MOT Test.

Had a 4-wheel alignment check & adjustments done.

126,006 miles.

HVB SoH stands at 92.5%.

Still on first LVB despite all the paranoiac twaddle about changing LVB after three years on these forums.

1,030 times on all charge stations.

694 times on home charger mostly to 100% taking in 34,143.3kWh costing £5,085.74.

336 times on DCFC charge points costing £6,382.42 for 9,594.86kWh.

Averaged 9.1p/kWh and 2.9miles/kWh.

Just WHAT a car!

Is there some documentation on the 80% number? I've read recently that 90% should also be okay, but if there is an added bonus to only charging to 80%, I'd definitely switch over to it if that's what's recommended.

No.

Ford reserves battery capacity, so 90% on a 91kW usable battery is actually (0.9 x 91)/98=83.6%.

Early on, Ford recommended charging only to 80% on a regular basis. It’s in my 2021 owners manual. At some point, I think within that first model year, Ford announced that they were relaxing that guidance and that 90% on a regular basis would be OK. And later models have that number in their owners manuals. So was 80% overly conservative initially? Probably. But I have left my default charge level at 80 because I don’t mind overly conservative, and I just don’t need 90% on a regular basis. That being said, I am not hesitant to charge to 100% as often as I need to for a long drive.
