12 Volt Battery ?

[Shayne]

December 17th

You have what I would expect still available to be updated. 21p22 updates were completed as expected.

Would not hurt if someone would run it again in a PM? Left a message and emailed my dealer. Will be following up Monday morning as this I need fixed. I want to plug it and forget it which should be possible.

Ford has replaced the Motorcraft battery in my 2018 Edge Sport 3 times !

It can, they just don't show it to you. Although it isn't very accurate. It only reports without a decimal. So it only says 12v or 13v for example.

Is that in FordPass where the LVB voltage is without the decimal?

Any idea what the available choices are for Battery Charge Mode? I found this in the Body Control Module of all places....

What would be the problem if the car just keeps on discharging the 12V until the vehicle no longer functions? 3 times now this has happened the most recent this morning. You would think with a huge battery and plugged in to 240V it could maintain the 12V for a couple of days? Tested here and not the case. Of course I understand ICE drain and alternator required but my truck can sit for months and the battery is fine. The truck has sat more than the car and it starts this morning cranking amps and all. Something is not right with this vehicle.

My Truck definitely could not sit that long without a jump start! Drove the car this morning and got the LVB charge back up to 12.8v. I have not had any problems so far, just monitoring the LVB with my Innova battery checker.

It is ice not plugged into 240V with a 100 KWh battery hooked up. Totally different tech. If you came home and plugged into a trickle charger every time with your truck you would be good; the same should apply if it is 240V?

I agree completely! Unlike my Truck, the MME has the capacity to keep its LVB charged up without having to be driven occasionally!

Yes. It it actually has a decimal but it's always 12.0, 13.0, 14.0, or 15.0

Either the car doesn't sent the decimal to Ford, or they strip it off when they display it back in your account.

Funny thing is BMS reports LVB voltage via LIN bus, I think it was directly to BCM with 1 mV resolution! Every 40 mS (25 Hz) when MME is on, usually every 15 minutes when sleeping. BCM shares BMS LIN data with other modules over CAN bus. Here is a sample (time left (decimal seconds), LVB voltage to three decimal places right):

This is what my vehicle reports currently on my account. I also monitor it in HomeAssistant with the fordpass integration, it will just jump between 12 and 13
