Preconditioning doesn't happen when car reaches intended charge level

[rhougey]

Howdy! I have a 2023 Mach-E Premium AWD STD battery and I use a Grizzl-E Avalanche charging station at home in Ontario, Canada.

I am having an issue where if the car reaches its max charge level overnight and says 'Charge Complete' in the app, preconditioning doesn't seem to happen the next day. I have preconditioning set in the app for 7:30am Mon - Fri. Typically overnight, somewhere early in the morning (say 3am) it reaches its max charge of 80%, but the next day when I go into the car it has not attempted to precondition the car for 7:30am and there is no message in the Message Center.

Yesterday by chance I connected the charger and during its charge I clicked 'Stop Charging' on the app. The message read 'Charging Paused' and funny enough this morning I finally saw the message in the Message center saying 'Cabin Temperature Ready' and the cabin was in fact warm.

Q: Is this normal behavior? If the car gets to "Charge Complete" does the car disconnect from the charger and preconditioning no longer work?

I have two Grizzl-E units. A black Classic in the suburbs (set to 32 amps) and a white Avalanche in the mountain home (set to 40 amps). I do not have this problem with either of them. As you know, the Classic and the Avalanche are both "dumb" ESVE's with no scheduling capability that might be conflicting, so it's hard to imagine that your Grizzl-E is part of the problem. I think your issue is related to settings in the car or app, or a malfunction in the car or app. Have you always had this issue, or did it only crop up recently with maybe a software update? What amps are you running at?

I do notice that the lights on the charge port are blinking when it’s preconditioning as I walk up to the car.

I believe you need to leave your charger plug into Mach-E in order to preconditioning your car. When leave unplug, mine won’t preconditioning even I have previously charged up to 85%. Mach-E no longer draws down your battery to preconditioning your car. Once it’s plug-in, it will precondition based on your schedule.

That’s the case for me over the past months.

I have a grizzle extreme and no such problem. Ensure your schedule is in the car in sync not just on the app. Delete all schedules in the car on sync, power off, back on and ensure they are gone and then set it back up sitting in the car. The app should switch and show you what the car is set for each stage also. This is a departure schedule problem and has nothing to do with it charging to 80%.

Walbox Pulsar Plus 40 amp, and I don't have any schedules enabled on it. But it is set to 20 amps, so maybe it should be more for the battery preconditioning to work? I will test for the upcoming Sunday trip...

I also use a Wallbox, and my car gets toasty warm with better efficiency when properly preconditioned. If you're using home assistant integration, you can slow charge at 20 amps, then when it hits target charge level, have home assistant automatically increase the Wallbox amperage to 40 amps to be ready for preconditioning the battery and cabin. I can't explain how to do this with home assistant, but it is possible. Mine automatically drops the amps again when my car leaves home, to be ready for slow charging when I get home again. It's super fancy, probably unnecessary, but my husband is having fun playing with all this stuff.

I have had the Grizzl-E Smart (set to 32Amps) and now the Grizzl-E duo (splits 40Amps between the cables). MME preconditioned fine on either one.

In one case it did not precondition every day for a week - it ended up being an update that corrupted the Departure profile. Everything looked fine in the App and in the car but I had to remove the departure time profiles and re-add them - worked fine after that.

I'm going to try this. I had a schedule and tried just turning off the switch in the app, but last night I decided to delete it completely reverting to a 'dumb ESVE' as you mentioned.

I'm going to try deleting all schedules on both the car and charger and seeing if at least preconditioning happens naturally.

Random one… did you set the departure times in the car or the app? My car will not precondition if I set or change departure times via the app. I need to do it physically in the car.

I've only done it from the app, going to try the car after deleting all profiles

My observation is that the preconditioning is for a shorter time when the MME is unplugged.

For me the fully charged SOC doesn’t restrict the preconditioning, but if you say fully charged at 100%, then I don’t know since I only go to 95% in winter.

You have schedules on the charger? That may be the problem. Open the charger to any time and let the car do all the scheduling. It can start a couple hours before departure when really cold and normally about 1.5 hours prior.

There is no preconditioning if you do not program a departure time.

There is no preconditioning if the car is unplugged. All it will do in that case is warm the cabin which would be why you find the time shorter.

I should have been more clear, I meant to delete all the schedules from both, and then set the departure times from the car specifically, not the app.

Therefore; clear anything on the charger to make it a dummy ESVE, delete all profiles from the Ford app, walk into the car and set the preconditioning from there
