Similar thing happened to me twice 5 months apart. But I was able to put it into gear and drive both times. But couldn't lvl2 charge both times until next morning when errors went away. The Ford dealer can't resolve the issue from happening again and suggest my charger could be faulty and cause...
Happened to me, it went away after hours or a day (I didn't get the error codes).
For me it might have been related to some residual plastic that broke off a prior lvl2 or 3 charge, and I notice it when I plugged/unplugged in at home.
While true, in my observations it'll only warm pack to 59F. I think for max range in cold, you'll wanna warm the pack up above 59F by using the work-aound in OP (but at the expense of pull more kwh from the grid). It's neat hacks/work-aound like these that makes the car interesting.
One can Yo-yo ones car for even better results. See recent id4 video on it from Kyle. 19 min to 60% vs 60 min to 60%, that's quite the savings with 30 mins of Yo-yo-ing
Has anyone been able to find out at what SoC % will battery nav preconditioning won't work at? Assuming 100% wouldn't work. I.e. battery nav precondition while 100% SoC in Garage plugged in level 2.
I think once they finalize preconditioning, it'll probably only be effective for climates that rarely gets below 25f, and assuming they'll increase/allow preconditioning to happen ~40 mi radius. As others said, 20 mi out is too short.
Probably a work-around is to rinse and repeat nav preconditioning until you reach your intended DCFC. A bit annoying.
Edit: this assumes 2 DCFC are 30km apart on your trip, often not the case
Just did another nav preconditioning, ambient was 42f, battery was 38%, 50f, and it got to 72f when I arrived at DCFC 15 mins away. I turned off cabin heat for most of this test in attempt to get the battery as warm as it can. Not bad.
Charging session was great, same as summer session speeds.
I'm able to confirm nav preconditioning works for me too. Even currently at 83% SoC, battery temp 44F, naving to DCFC 30 min away. The heater is taking 6kw w/ cabin heat set to off. Woohoo.
I noticed no regen the other day after I charged to 100%, so it would imply the unlocked usable capacity are indeed at the bottom end SOC as reported (I'm 21' job 2). But I think it would be wishful thinking Ford unlocked even more for this winter.
