Am not affected by charge-gate, rather, as I continue to advise here, my car "looks" like it's affected by charge gate, but the truth is that it has always charged this way due to having original "A" pack battery as our car is early 2013 Tesla S85 VIN near 6000.
I have a monitoring device that logs all trips and charging (FleetCarma) for many years.
I provided a number of the longest charge sessions in a post last month.
These showed that charging above 90% is slow for my car, and always has been.
Whereas charging up to 90% typically followed a pattern of:
(state of charge in percent) + (kW charge rate) =~ 110
I did a ~10% to 90% supercharge within the past week.
The battery was pre-warmed significantly using Bjorn Nyland documented method of hard acceleration/regen.
Within a few minutes of starting, peaked to 90 kW and the formula for the charge rate was roughly
SOC 10%, rate 90 kW
SOC 40%, rate 70 kW
SOC 80%, rate 25 kW
but once the car gets to 85%, the rate dropped quite a bit, and I don't even try to supercharge above 90% when not necessary, but that's nothing new.
Started the trip with car charged to 413 km range (out of 425 km as new) at 100%.
