Thanks, your posts are very helpful. I'd like to ask:
What has been the cold soaked, not trip, but your return home Wh/mi, ~10F?
What range remains when you arrive, vs. leave work 8hrs later, in ~10F temps?
How many additional miles of rated range do you lose, to get home. More than the ~30 you travel, I presume?
Preconditioning distorts winter efficiency, because your wall and not the battery is providing some of that winter energy. Watt-hours from successive trips w/o chargers, say on vacation, etc., answer a question a few of us have and are also where I thought The Limiting Factor's concerns came from. For example, I had to learn (after 4 MS's) that it takes about 40 miles of range to go 20 miles, if the car has cold soaked at about 15f (ie, not plugged in). With LFP, I assume it would be worse. Reading daily average consumption with a pre-condition, or FTM "lifetime" Wh/mi averages doesn't distill the answer to the "LFP in cold" question. Neither did Bjorn's test, in my opinion. At 0C, or 32F, having an extra ~5KWh, pre-conditioning and basically never cooling down really helped, LOL.
Also, helpful to know the following regen numbers. I still get 60KW on my older (not updated) MS, while wife's "updated" car hardly ever leaves cold-state / gimped regen. That's at 5K lb. At a Model 3's ~4k, 37k is probably good but can't imagine 8KW feels like much?
