That isn't preconditioning. If you set a departure time (at least a couple hours in advance), the truck will heat the battery was well as the cabin, which will significantly help your winter range.
I had the departure time set in the navigation system, the battery was preconditioned. I was just adding that on top of that, it was in a heated garage, etc... Battery temp as dead center on the indicator, and according to my CarScanner apps history it was 54F, when I started out. Safe to call that a preconditioned battery?
No, a preconditioned battery would be closer to 85 or 95. Setting a time in the Nav system won't do it, you need to set it as a departure time in the charging settings.
I don't believe this is correct.
You're supposed to turn the heat off when DC charging per Ford.
If you set a departure point, but you aren't plugged in, it likely didn't work. You should plug in well before 30 minutes in advance of departure.
I was referring to the battery heater not the cab heater, I had the cab heat off most of the drive, just toggling it to clear fog from time to time. That said, I rather hope there isn't any potential for damage by running the cab heater when on DCFC because at 4F outside, I'm not turning the cab heat off well I nap for an hour.
Its probably true that the feature didn't work based on how I plugged things in and what not. But the entire truck was in the garage overnight and all day with the garage temp set to 50F. So the entire truck was 50F at departure, regardless of conditioning or not, app reported battery as 54F at departure. Considering it was 8F when I hit the road, that should still be big leg up for the heating system vs being parked outside all day.
There is one heater. It heats the battery and the cab. Ford suggests turning it off during DC charging in the winter, because they're trying to use it to keep the battery warm, and you're pulling heat into the cabin. Running the heat won't damage anything, it will prolong your charging session by a) having the battery be cooler and b) using energy that the charger has to replace.
There is one heater. If you heat the cabin, it's providing less heat to the battery. Simple.
That makes sense, for some reason I thought there was a separate system between the battery vs the cabin.
This is something I’m digging into a little deeper with my limited knowledge of the system design/operation. While there maybe one heater for both, my anecdotal observations of my CarScanner data from the Coolant Heater Power PID is showing it draws Power only when the E-Heat is in the ON position, even with a Battery Temperature in the mid-30s degF.
. 
This diagram of the Mach-E system gives us insight on how the Lightning system might work, though the Max Tow package would have 2 AC units one dedicated to battery and the other to the cabin.My concurrent Coolant Temperature readings are showing 59 degF, so I’m trying to verify that PID is a reading associated with the Battery System; but, there appears to be at least some subsystem that heats the cabin that has a differentiated Power draw
Any additional insights are appreciated
