Not all bad those Mach Drops were moved to mid-January completion I guess.
Really appreciate your post on pg 17 it brings some clarity. Yours went to the speedway on what date?

Hope this clears itself up and goes away. Hope mine goes into drive on Monday and I get it back. Right now with the world sh!tshow we have going on just hope all stay safe. Small bug not the end of the world; stay healthy.

1/13 Left KC
1/15 Arrived Wilmington
1/23 Back in KC
1/27 Leaves KC

However, there was another listing on 1/25, so I think It spent 2 days at the Speedway.
I'm also not sure mine got new software at the Speedway.

How were you able to track by day and location? My Palsapp only shows KC and dispatched?
Vehicle Visibility. Palsapp was worse than useless for me.

Can you say whather the current thinking is that which cars may be affected? Or some general idea of what you think on that subject from what you have experienced?
I don't actually know which and how many cars might be affected. It is my understanding that a different vehicle configuration (e.g. AWD vs RWD or SR vs. ER battery pack) may require different software. So it's possible the issue simply does not occur on certain types of cars at all.

(Sorry for the delayed answer.)

Just an update for those wondering...

It has now been 5 days since the software was updated on my car. I connected the car to my ChargePoint Home Flex and have been monitoring it. (This is a crop of the charging graph from my ChargePoint app):

Ford Mustang Mach-E Marlin's Dead Low Voltage Battery (LVB) -- Followed by Stuck in Park IMG_1708.PNG


The car has been plugged in for about 5 days but this graph only shows the last ... roughly 18 hours.

You can see that the car wakes up to take some power about once every 6 hours or so -- while plugged into the charger. I'm monitoring the state of the 12v battery and so far, since the patch was applied, it's a happy car.

This is good news ... the car is doing what it is supposed to do.

So is there a software version tied to your upgrade that we can see on a screen somewhere?

Is the car charging from EVSE during these spikes? I assume not ?

I think this the course of action even before the update as I’m experiencing the same on the demo MME I have. Wakes up to briefly charge after a full charge to set point.

If you happen to catch it when it's charging you might notice it will say if it's charging the 12v battery.

There are a lot of systems on the car that run off the 12v battery. The 12v battery is only a 35 amp hour battery (no need for a huge lead-acid battery... it doesn't need a crank a starter).

When the car is off, it puts most of the systems to sleep ... but a handful of systems have to stay awake at all times ... so there's a constant draw on the 12v.

The car does monitor the charge state of it's 12v battery and will periodically charge it to prevent it from going flat.

If the car is not plugged in (e.g. parked out in a lot) then it will periodically take power from the big battery.

If the car IS plugged in, then instead of drawing power from the big battery it will pull the power from the EVSE.

My car is scheduled to only charge during off-peak usage periods. But it will do these periodic charges on the 12v anytime it wants (including during peak periods).

You can see from the graph that it's not a lot of power. My EVSE is 240v @ 48 amps (11,520 watts) ... but when it wakes up you can see it never takes more than 1,000 watts and that only for a few minutes (if it ran for a whole hour it'd be 1 kWh ... so it's really just a few hundred watts).

I noticed last night that my 12v battery started charging in the middle of the main battery charge. Car was charging (90% goal) and at 87% it started saying "Charging 12v battery" then eventually finished the car charge to 90%

Based on your post - I monitored Juicebox40 app last night (first time charging the MME) and I did not see any such spikes. I will keep monitoring this week to see if the car wakes up to do this. Are you setting the EVSE to control charging times, %, etc or on the MME. Just curious.

My charging schedule is controlled by the car to only charge during off-peak. I could set the charging schedule in the charger ... but opted not to do that.

If you told your charger to only allow charging at specific times then it might explain why you don't see it periodically draw power.

This is why I’ve not been a fan of allowing the charging stations to control the timing of the charge (instead of the EV controlling charge timing) - the EV periodically needs juice to warm up HVB, charge the LVB, etc.... In my view, it’s best to have the juice ready/supplied by the charging station.
