I really wanted smooth charging curve. Now that GM implemented smooth charging curve, I don't want it anymore :) I guess I should have been specific with my wishes...

Interesting. Looks like the taper starts at ~42% SOC instead of the old 50%.
Yes.
The more I look at the data I have on my sessions, the total kWh delivered by time up to 65%-70% seems about the same (before and after the update). So I'm satisfied.
I initially thought it was charging slower, but after looking at my data, I realize the variances are minimal. More likely attributable to misc factors than the new charging curve.
I have only done 3 EA sessions since the update; and i suspect the first one had a slow unit that wasn't delivering max amps for whatever reason.

35634


Keep in mind, these are kWh pulled from the EA unit, not delivered to the battery. One may probably estimate 10% losses if you truly wanted to know how many kWh made it into the actual battery.
My usable battery is around 55kWh fyi.

FYI: Eric Way / NewsCoulomb just did a brief test as well for those curious.

With the new charging curve, the maximum DCFC speed only goes up to 42% of battery capacity.

However, with the new advisory to avoid discharging to below 70 miles of remaining range (= 29% based on EPA range of 238 miles), that means that the maximum DCFC speed is available for only 13% of the battery capacity, or 21-22% of the "safe" battery capacity under the new advisory (59% or 61% based on 29% to 88% or 90%), instead of 42% of the battery capacity.

This means that, in addition to losing 39% or 41% of "safe" battery capacity, customers with recalled cars will also likely see slower DCFC, which they may need more often due to the smaller "safe" battery capacity.
