Interesting but i am not sure i believe it.Throttling itself isn’t new, that was identified some time ago. A chap who exclusively DC charged noticed the charge rate dropped, and he’d been careful to charge and stay with 20-80% limits most of the time. Another owner received this from his SC after his car had been tested:
‘The DC charge limiting is set to start at 2625 kWh and reaches maximum derating at 13125 kWh.’
I have over 32,000 kWh Supercharging and mine is throttled back only after the last updates. My charge times are longer now only because my pack capacity is artificially limited and I now have to charge from 15% to 90% instead of 30% to 90%.
Since my new 100% is my old 85% I SHOULD never see the charge current drop. My batteries NEVER get above 4.1 volts.
A fellow here has even more Supercharging than me at over 35,000 kWh and his battery has not been limited.
