Here's just an example of some data I logged on my car over a series of four supercharging sessions. These were at different locations during about a 600 mile drive all in one day about 6 weeks ago. The first charging session wasn't until after ~3 hours of interstate/highway driving so battery was fully up to temp in all cases.Thanks for this. I’d wondered about it… I am learning.
Again, this for a mid-2016 MS90D, so not exactly that curve that newer cars may see, but gives you an idea of how charge rate taper with state of charge (SOC).
The peak values around 140kW are actually really, really good for this vintage of vehicle, and frankly, some of the highest I can recall seeing. For comparison, when I first got my car, peak charge rates were 120kW for a Model S. While some with older MS cars, especially 85 packs, have seen their charge rates severely reduced/limited, my MS90D with ~62k miles, about 40% of which done by supercharging, is still holding up pretty decent for charge rates.
