On my past few trips, I’ve cancelled the pre-conditioning when it appears in the NAV display on the way to the SC and I still have a completed charge when I arrive back at the car, so the charging is not slowing me down appreciably.

I always check the initial rate of charge before leaving the vehicle and it is usually under 100kw/h (SCV3). I can’t tell what the charge rate was when the battery completed charging. My SOC before charging is about 42% and I charge to 53%.

As an aside, boy I wish the car’s screen would have the ability to dial in a specific charge level, not try by fiddling with the triangle beneath the battery display. I have to resort to the app, which seems silly.
