Took off from home this morning after topping up to 80% SoC (180mi range indicated). Also noted that as soon as you hit 80% the charger shuts off so if you want to try and ride the taper on the Level 3 charger I think you are out of luck. The battery was still charging at around 24 kW when it hit 80% as well. Oh well, I would have liked a few more miles in the battery. Update: I just realized it did not stop when it hit 80%, it stopped when it hit the 30min time limit. My actual SoC when I left was probably around 70-75%. I'll be more accurate on the next leg...
First stop is Delano CA at an EVgo station at a Walmart 140 miles from my start and I made it here with 14 (shows 18 but I was on the 14 mile side of the meter) miles of indicated range. Total battery use was 40.2 kW (75-8% SoC) which is ~287 Wh/mi or 3.48 mi/kWh. Speed was mainly set at the limit (65 or 70) but going up the grapevine really sapped my range although I did get back maybe 5-6 miles of range on the 5-6 mile downhill. It was also raining a bit so I am sure that did not help as well.
Overall the car is driving fine, lots of time in the right lane obeying the speed limit! The weather is pretty cold, around 45F, but I have the cabin heat off to save power. Much like your grandma's house you need to make sure to wear your sweater. It does start to beep at you around 30 or so miles of range left to stop and charge but it was not super annoying.
Charging now I am getting around 40-40 kW off the EVgo 50 kW charger, the car indicates a little more than an hour to hit 80% SoC and the charge session did stop after around 30 min. I spoke with EVgo and this is something programmed into the stations so if you want to charge more than 30min make sure to stick around your car to restart the session. The car does make some fan noise while the battery is charging but it is not too loud.
Time for the next leg...
Cabin heat: Off
Total kWh used: 40.2
Efficiency: 287 Wh/mi or 3.48 mi/kWh
Charging start: 11:22am, 18mi range, 8% SoC
Charging finish: 12:50pm, 187mi range, 83% SoC (Also includes three calls to EVgo to start charging sessions Update: Spent 6 minutes on the phone with EVgo)
