Is there pre-conditioning when preferred charging start time is set?

When you are level 1 or 2 charging at home with a preferred start time, does the car precondition the battery in advance of the actual charge start time?

No

No, because that would draw power before it's allowed to do so (preconditioning draws power from the wall). It will precondition when the charge window starts, if necessary.

Are you people sure? When I precondition my car on the morning, it first starts a process roughly 30-40 minutes before departure that is named “preparing to drive” in the app. 15-20 minutes before departure the messages changes to “precondition cabin”. To me it’s seems like it does both. If I only give it 15ish minutes before departure time the car uses a lot more energy the first minutes, which suggest it heats up the battery. Maybe it’s only the eurotards cars that are doing this while you freedome ponies decides precondition of the battery is silly

That wasn't the question. The question was regarding CHARGING, not preconditioning with a departure time.

For a departure time, it warms (cools) the battery, then preps the cabin. It can take over an hour for the first phase.

I'm not even sure if when one is using Level 1 to charge a MME whether preconditioning in winter might even be able to occur if charging is happening simultaneously. Does anyone have a clue about that?

Nothing happens simultaneously. Either you're charging, or your preconditioning. If you set a departure time, then the car, if plugged into 220v, will start warming the battery. If there is sufficient power left, it may also climb slightly in charge percentage, but the warming of the battery in cold weather takes a lot of power.

On 120v (level 1), it will not precondition the battery, can't come close. It will warm the cabin, just takes longer.

Didn't know that Level 1 completely does no battery conditioning prior to departures. No warming or cooling battery conditioning ever occurs prior to departure on Level 1 EVEN if several hours remain prior to departure time while plugged in AFTER the target charge level has been reached?

Virtually none.

The heater pulls 5+ times what 120v provides. There are posts on this.

Rick, Do you know if preconditioning on the Mach-E 1. prior to departure, or 2. prior to upcoming charger, incudes cooling the battery in summer (in addition to ability to warm it in winter). I believe in late 2023 only heating was available for #2, e.g. to warm battery when approaching a charging stop but not cooling for hot summer temperatures. Curious if that has changed so cooling is available for both.

Cooling of the battery would only happen if it was very hot. A car sitting in Michigan overnight is NEVER going to have to cool the battery for preconditioning the next day.
