What charging speed does your car taper to over 90%?

[DblOSmith]

I know that all EVs taper near the top, but suddenly my MYP seems to be more than usual suddenly. Hooked up to my TWC set to max:

Up to 93%: Charges full speed 11.5kW
93%: Drops to 5kW
95%: 4kW
96%: 3kw
97%: 2kW
99%: 1kW (and I haven't ever gotten to 100% where it stopped in several months)

While supercharging, I'm used to the 80-100% taking as long as charging the bottom 80% and it seems to do that normally (although I haven't SCed up to 100% in almost a year), but at these home speeds, 95-100% takes several hours. That is new. Is this the case with anyone else? Is this normal? Do I need to just let it max charge to recalibrate the batteries or whatever?

My M3LR tends to drop to about 7kW at 90%, tapering to 3 kW at 99%.

I have only one good full charger recorded on my MY, and it pulled the full 10 kW up to 99%, then tapered down to about 2 kW as it reached 1000%.

If you suspect a BMS issue, then you should drive to a low SoC and then charge back up. Or, perhaps better yet, perform a battery health test from the service mode.

It's also possible that the wall connector is reducing max output current due to overheating. Although it would seem unlikely in winter, I have issues with this if I charge on a summer afternoon with the sun shining on the charger connector. But,, it's worth checking the Tesla app to see if the max charging amps has fallen back.

On my old model s 85d battery I've setup a bed in the back of the car, fell asleep at a supercharger and it took 3 ½ hours to get to 100%
