What is your SOH? Milage? and how do you use your Battery?

[Maxx]

My SOH dropped to 98.5% around 6K and now at 9K immediately after a 1 minute 4kWh supercharging (at 168kW), SOH dropped to 98%. Battery temp was around 70. Ambient temp was in 60s. And I have extra cooling in my pro. I have no idea why this short charging session should shave off my SOH.

Apparently following is how it works but I still can't figure it out. I have had less than 20kWh of DCFC for the life of the vehicle. Almost all charging has been Level 2 at less than 32kWh. For over 95% of it's life battery has been sitting at SOCs between 40%-60%. It has been charged to 100% maybe once and sat there for less than 15 minutes. Even for my long distance trips, I rarely go over 90% SOC, 95% on a few occasions. I usually let the battery sit after driving for a few hours before charging. I charge during day in winter and at night in summer. I try to keep my lead foot under control as much as possible. I could not baby this battery any more but my SOH seem to be way bellow norm. Now I am afraid of fast charging. I don't know of a way to slow down the fast charging session

By the way I have not done any of the CSPs. My module voltage variation seem normal.

Would you guys please share what is the age of your battery, SOH, milage and how much DCFC you have had? And any other info you care to share about how your battery was treated like how often you floor it or charging/driving with cold battery. If any of you have measured the energy your battery is holding at 100% SOC along with your SOH, please share that too. May be with enough posts on this threat, we can figure out how this works.

I monitor mine and my son's Mach-E for grins. Note that it is always presented to the nearest 0.5%. So yours didn't drop from 98.5 to 98. It likely dropped from 98.25 to 98.24 (or less).

I'm at 99.0% at 7500 miles and 18.3 months. DCFC 6 times to 80-85. L2 charge to 80%, a few times to 100%.

I’m at 21k. 98.5 SOH. I have only DCFC’d less than 10 times.

 

[Pioneer74]

35k miles. 97.5% SoH. Rarely DCFC. Charge to 90% during the extreme winter months, drop it down to 85 the rest of the time.

Do you remember roughly at what mile you dropped to 98.5, 98, 97.5?

You should stop looking. Your level of concern is totally unwarranted. Unless it is 100% charged and 77 degrees, it isn't accurate.

Mine hit 100% again during my trip out west. Now it is 99.5% again.

I have DC charged maybe 40 times (have to add them up).

Relax, don't worry, have a beer...

I have no idea what my SOH is and I don't know what I'd do with that information if I had it.

I've only checked it once.

Are you saying your SOH went up? I didn’t know that was possible.

 

[Heliian]

The warranty is for below 70%.

Forget about anything above that for 8 years or 100k miles/150k km's. (yes, Canada gets screwed out of 10k km's.). But, we did get our fcsp before the truck!

You will lose battery capacity as time goes on, if you figure out how to slow or stop it, please let us know.

It is a good thing to know if you like to worry. That is probably what Ford uses for warranty but I am not sure how good it is if they can change it.

p.s. We use OBDII port with Car Scanner to see it.

I am hoping we can use this thread over time to connect some dots. It is a long shot but we got nothing else to do around here

I am like Rick. I am at 10,XXX and at but at 7,000 it was showing 99.5% so somewhere around 99.74-99.76.

I have DCFC when needed but less than a dozen times. The rest of the time is charged at 32 amp or less and usually to 80% with one a week 90-95% for a weekly commute then I charge once a month to to balance the cells.

Then roadtrips where I charge to 95-100% depending on if I need it for the trip.

 

[Jseis]

15.5K miles at 100% SOH and typically charge to 80% daily (90-100 miles per day commute).

 

[luebri]

so the conclusion is SOH reading is complete voodoo? just like getting OTA updates?
