Here is the charging curve of the GT-P for reference and captured in a thread related to an update:
Key: State of Charge, Charging Rate
6-10 : 320 (Step-up from 180 over a few seconds)
10-15 : 320, 300
15-20 : 300, 290
20-25 : 290, 270
25-30 : 270, 250
30-35 : 250, 225
35-40 : 225, 195
40-45 : 195, 170
45-50 : 170, 155
50-55 : 155, 150
55-60 : 150, 155
60-72 : 155, 150
90-91 : 65, 55
91-93 : 55, 50
93+ : Slow Speeds
31 minutes for 5-80%. ~10 minutes for 80-90%. I think it is something like 30 minutes for the last 10%. Don't quote me. All I know is that it takes forever that last 20% overall.
1-2% to 5% is basically the car rapidly stepping up to 320kwh. I know it isn't included in the above, but that has been my general experience.
Please let us know what the new 24 GT does. I am very curious. Don't get stranded trying to get the car really low for tests of charging speeds.
My suspicion is that the heat pump would keep the heat saturation down better than my GT-P when temps are 100+ on the asphalt. I saw significant throttling by the car (didn't say it was the charging station) just last week as low as 55% State of Charge with the above rates reduced to only high 80s kWh.
