Found this on [banned site] info is for Mach E’s, but I’m assuming pertains to us as well. For all I know this info might be on here somewhere, but I found it useful so figured I’d share.
So purely out of curiosity, guessing it wasn’t gonna work, I tested the method of just heating the battery by turning cabin controls off in my departure time OFF plug to see if anything happened at all. Oddly enough, the cabin controls came on anyways and started heating the cabin to 74° although it was a brand new departure time I had created and double checked that indeed cabin temperature was off battery was cold as a stone.
I was going to experiment with strategy C, I have never done that, previously.
Normally I use strategy Z in the deep of winter, delayed charging to early am, then a remote start when I'm getting ready to go out, doing this 15 minutes prior to leave time.
In my personal use, the extra performance for a typical 10 miles of daily driving isn't worth the extra 5 to 6 kWh to warm the battery directly with departure timer.
