Noticed HVB SoH is at 97.5% with battery age of 13 months

[vortex_walker]

Just today I was looking at OBD readings and I noticed HVBSOH dropped to 97.5% and the battery age is shown as 13 months. Is this normal?
How fast do these batteries degrade? I only use Level 1 chargers day to day and use Level 3 when I take long trips (400 - 600 miles), which is once in 2-3 months.

I cannot speak for the MME, but for our last car, a 2018 Tesla Model 3, the first year had the most degradation (3%), then for the next 4 years only about 1% total.

Okay. I was wondering if it had to do anything with my driving style.

Hard to say if this is normal without other information:

• What model year
• When was car built
• How many discharge cycle

If you have a '21 than that would be awesome.

2023 mach e Gt. I think the build month was June or July.
Does the discharge cycle mean dropping the charge level really low and fully charging? then single digit.

July '23 was 13 months ago

I have a 21 CA edition with 78949 miles and SOH is 91%

I have 91500 miles on my 21 premium 4x. I did a (think I did it right) battery calibration running the battery down to 15% charging to 100. Prior to that it had been 91.5. Now it shows 88.5.

OK, I will give myself up to the onslaught. I know, always questions about battery duration and degradation on the Forum. But I do request your interpretation and suggestions. My battery duration seems to have slipped significantly. I recently took a 2 week road trip 1,200 miles, Portland, Oregon->WA->MT->WA->home. On the road (HVDC) I never charged >80%; at home in preparation for the trip to 95%. (At home usually 85% with level 2). Odometer and range mileage were close except 88% when I drove 80 mph in the 90 degree weather; I stopped that immediately! Now I am reporting range only 160 miles at 70% charge, (that would be about 210 max!!).

Car is running fine. Have not had HVBJB replaced. I don't drive it hard, look I'm 77 years old. I tend to understand mechanical, not digital; I don't do OBD. Before the trip we had a 20K check (rotate tires and eyeball for problems) tho I don't know if they looked at the coolant fluid levels under the frunk covers.

But I am planning another 800 mile trip this weekend.

My MME is a 2022 August-built. Premium ER eAWD. 27K on the odometer. Charged to 100% less than 5 times. I had a Nissan Leaf for three years before the MME, I was waiting for Ford to come out with the MME, so I have some experience.

THat's not a symptom of impending HVBJB failure, is it? Should I just push the factory reset button? Call Ford Central? Take it to my dealer? (I think they're good). Fahgetaboutit? Not take it on this next trip?

Thanks for your thoughts.

Oh, and I have never discharged below 20%...

here's all the data you could want input yourself as a datapoint and track yourself going forward while you're at it

https://www.macheforum.com/site/thr...-analytics-crowdsourced-data-add-yours.38065/

you are right at the trend line based on age btw, maybe slightly above

I have seen a lot of data saying not to charge to 100% if you do not need to. If your only using 10 to 20% of your battery daily, charge to only 70% or 80%, yes they say the Mach-E will lose soh the first year or so then stabilize.
