The lack of disclosure is, sadly, becoming less surprising. I'm hopeful Tesla will start to move away from doing this stuff quietly without owner awareness. It's best we know up front, but if they discover something later, just
let us know.
Regarding this specific issue, there are some outstanding questions. One of which is whether or not the peak rate continues to diminish, and if so, what's the formula for that reduction? Another question I have that
@Naonak can answer is whether the curve is flat at the beginning now, and then tapers in conjunction with the original curve, or if it tapers immediately. I assume the former. Tesla is trying to keep the battery from exceeding a particular C rate, so capping without disturbing the taper curve makes at least some sense.
I have a hard time coming up with 10 minutes in theoretical calculations. Do you have some data that we can reference? It looks more like 3-5 minutes from what I can tell. 5 minutes if the taper curve begins immediately, and 3 minutes if it's capped. But that's really just eyeballing a charge from 10% to 90%. This experiment
was done in the past by
@Owner with the 90kW "A" packs vs. the 120kW capable packs and they came up with 4-5 minutes.
I'm not suggesting we discard your complaint, but it's useful to be accurate about the time difference per charge at the reduced rate.
