What is your SOH, Mileage, and how do you use your Battery?

[snb2557]

No towing and I don’t think I’ve ever hauled anything in the bed too heavy. I do live in Texas, so plenty of heat. I keep it in a garage when not driving / away from home. I also wondered if something hadn’t been reset ?‍. I was told Ford had to arrange for assistance when the dealer started doing the module swap.

Look at it this way; If the battery is good and BMS is confused, you may get your battery upgraded before your warranty is over because BMS thinks your SOH is under 70%.

You could do your own calculation next time you charge to 100%. Look at your actual SOC and energy in Car Scanner and go down to 20% and do the math to see if your actual battery capacity has dropped by something close to 93.5%. This is not fool proof since some of the data you are using may be the same false data that confuses BMS but at the minimum is additional info for you.

I had 1% drop soon after some of our hottest days here followed by a short fast charging but it may be a coincident. You can compare notes with other owners in Austin.

8400 miles. 100% SOH. Fully charged it shows 131.07 kWh. I charge to 80% nightly and 100% before a trip - probably only 5 or 6 Times so far. I’ve probably DCFC 12-15 times - half of those on Tesla superchargers with peak rates as high as 190 kW. I’m not easy on it and have seen over 450 kW draw from the battery during takeoff many times.

I noticed my variation in battery module capacity has gone down after charging to 100% - it was over 16 Ah when I bought it, went to 9.8 the 2nd time I fast charged and now it’s 4.2 Ah.

I thought I had a good printout of the FDRS battery report, but it got truncated

If that soh is true, you should try to let your battery stay at 100% or 0% longer, so that you will have the soh droped below 70% sooner, and let Ford replace a new battery pack for you.

The reason why SOH is 100% is the module replacement. It takes 22 days for the BMS to be accurate after that work, per Ford.

Display SOC is what shows in the vehicle.

SOC is what the actual battery has., including what you can't use.

It has been over two months since the module replacement and my SOH is still showing 100%.

Getting nervous with my 2022 Lariat LR battery SOH since it started jumping all over the place.

(dates are estimates from when I first noticed it)
04/01/25 - SOH 100%
04/15/25 - SOH 99.5%
05/01/25 - SOH 97.5%
05/15/25 - SOH 98%
06/13/25 - SOH 96%

4% loss in 10 weeks seems a little extreme given that I've been at 100% for a loooong time until recently and treat it so well. Only DCFC 3 times and keep the charge anywhere from 40% to 70% on the Ford slow portable charger. Truck just hit 30k miles.

Any way I can diagnose the battery modules myself with Forscan or some other tool?

Thx!

That's normal. The reason it shows 100% for such long time is because of it's eating the buffer, which is around 8% of total capacity. After that, it will start to eat the usable capacity....

Hmm. Not sure that sounds right. That would mean my battery has lost nearly 11% of it's total capacity which would definitely not seem normal. When I look up data in Carscanner, it clearly shows a difference between SOC and displayed SOC, so the buffer still exists.

Could be BMS drifting is an issue. Basically without going down to near zero, or 100% the BMS can lose track of actual. The SOH you are seeing is what the BMS thinks, and that may not be entirely accurate. Many people charge to 100% occasionally for this reason. I have read that the remedy is to run it to near zero, then in one continuous charge to 100% (meaning it shuts off on its own). This also has the effect of leveling all cells, meaning evenly charged which can throw off SOH calculations as well. Lastly, it's not just battery usage, it's also age of the battery pack, and environment, especially very high temps. But of course you may have a weak cell or two.

Try deep discharge to absolute full charge. Just keep it either end for as little time as possible.

That does seem like a fast drop. Have you had any software updates to BMS in April? I am thinking if it stayed at 100% for that long, may be it has been lying to you all this time and now it is trying to tell the truth a little at a time.
