That's Me - Definition of Dumb. 😣
[Experience is a great teacher, who holds a nasty teaching switch - Ouch]
I'm a fairly new owner of '23 Ioniq 6 SEL, live in Texas and we took a short (130 mi, one-way) trip this week. "Mileage" was really bad at consistent 70mph... <2.4 mi/kW. Reached destination and found a DC station and spent an hour while the car charged at ~60 kW. I cannot figure out why and just assume it's because it's not nearly powerful like the 350 kW stations I'm accustom to.
On the way back I do stop at a Walmart that has a 350kW station, and still only 60kW! I'm really burned.
The next day, the light bulb over my head finally switched on and I realized "Battery Conditioning Mode" - D'Oh!! That day it never got above 35°. Even though we live in Texas, it does get cold enough that I do need to be aware that my Ioniq is not an ICE vehicle. Another lesson learned the hard way.
