Cannot trust my truck to stop charging at 90%

[TaxmanHog]

It sounds like my understanding is correct that you can not do that in the truck with none Ford chargers. Do you think this can be fixed with OTA? Or truck needs additional or different hardware to be able to set charge rate?

I have no experience with EVSE units from other manufacturers, unlikely Ford will integrate remote control of them. If anyone knows better, set me straight.

I find this interesting. We own a Tesla and can easily access the charge level via one touch on our screen. It's a sliding toggle type thing and we can set it at whatever level we want the charge to max out at. From reading your posts, you are saying that there is no way to set the charge level manually from the infotainment system inside the truck or via the app? ?‍

You can do it both in the truck and on the App. No different than Tesla. The biggest difference is the App UI is superior for Tesla.

Ford mobile charger is stuck at 32/30 Amp unless the source is limiting to less, is that correct? Or there is anyway to reduce the current on that?

Nothing limits the mobile charger. It will pull about 30 amps with the 14-50 plug and 12 amps with the 5-15.

Are you using 120v or 240v?

240

Charging to 100% 3 days in a row isn‘t going to hurt your battery if you drive it every day. Battery deprecation is a factor of how long it sits at 100%. Also remember that there is headroom above the 100% of useable capacity.

Yeah but the exact effects won’t be fully characterized for months or years and I need this truck to last. I’m not rolling the dice.

100% charge shown the truck is not even a 100%. An OBD2 app will show true SoC at the 100% display on the truck and it’s closer to 90% . But I understand you want it to charge as you have set.

And why can’t ford let you set charge times on something other than the hour mark? My cheaper rate is 11:30pm-7:00am. For some reason if I manual set 12am-7am it charges immediately but not full current it cycles on and off like every 30 seconds. But if I select my utility based ToU on the Ford app it sets 11pm-7am and works fine. But 11pm is incorrect. It’s only 30 minutes at the higher rate but still is annoying

How does that matter? I’m not hooking up an OBD every time I charge. 100% indicated is 100% as far as I’m concerned. That extra reserve is in the noise as far as im concerned. And the 100% isn’t even the point. The point is the continual failure to properly control the equipment via the software despite the multiple workarounds duscussed here and in other threads.

I never meant to hook up an OBD2 adapter every time you charge. Since I have done this I was just sharing to it will show you the true battery capacity. It was as I can see an unsuccessful attempt to calm your fear of damage because 100% on the truck dash display or in the Ford app is not 100%. It is actually about 90% of the true capacity of the battery.

I have my charge limit set to 95% and use a ChargePoint Home32A, works every time.

I’ll try it next week. Not gonna risk going to 100% three days in a row.

I would not stress over 3 days at 100%.

I charge mine to 100% once a week or every 10 days depending on how much I drive.

There's a SOC buffer built into prevent over charging the cells.

After all, 9 year warranty tells you that Ford has designed the battery to last quite a long time - much longer than the 12V 35AH AGM....

8 year (or 100,000 miles), but yes.

Ford software is far superior to some other brands (VW group, for one), but they refused to include a GLOBAL CHARGE LIMIT. Like, why??

It's no wonder the Lightnings I saw at dealers were at 100%. They made this way too complicated. The idea was nice, but Ford really needs to add a global charge limit OTA.

Also, I don't see how 100% displayed would equal 90% SoC. The buffer is split between top and bottom of the pack. It's highly doubtful that they blocked off 20% of the battery especially given the requirement to adhere to a charge limit.

They’re at 100% because the pre-delivery checklist says to charge to 100%. They shouldn’t do it until they sell the truck, but laziness is a factor. Mine was at 86% when I picked mine up. Salesman told me that’s what it was when it came off the truck and I told him to not bother charging it any further.

Correct, the buffer is about 10%, split between top and bottom.

The 90% charge limit is not a requirement, it’s a recommendation.
