From approx. 50 % SOC the amps are reduced stepwise, but in the end you still get an average of 19 kW.

Well in your case the battery already seems to have had some thermal energy already, thus the early throttling.
I have recorded a few charge cycles since 2020. All observed rides have been started with a charged and balanced battery in circa room temp conditions. The ride was relaxed, no speeding, but also keeping up with the traffic or speed limits. All charge cycled done starting between 10 and 35% SOC up to 90%. Landscape rolling hills.
I observed a drop from the charge plateau at 22/23kW to 20kW around 65%SOC and fall below 20kW at circa 75-80%SOC with dramatic drop in charge speed afterwards.

To my experience the charge rate is only dependant on the battery temp. According to a Energica Tech there are more than 30 sensors in the battery pack. I guess, that the highest sensing Temp. sensor is controlling the charge rate. The outside temp. is only relevant if you charge before the ride, because the battery heats up while you're riding or charging.

Depending on your riding style and weight: The faster you ride and the heavier you are, the hotter it get's. Today we have temp. here around 25° C ( 77° F). After the ride today I started at 5% with 33° C battery temp. and 22 kW charging rate. At 17% it already started to reduce the rate, because of the temp. rise of the battery. In earlier trials I saw the tipping point around 37° C. At 60% SOC the rate was down at 13 kW and stayed there up to 83% SOC. After the charge the batt. temp. was at 42° and batt. symbol on the screen was yellow.

I hope I could give some information on that. I made a time laps movie on that but the size of it is too big to upload. Maybe somebody has an idea of how to.

Like  maybe ?

Thank you for the hint Matthias!

many of those sensors are probably voltage sensing for the branches of the entire bank for balancing too.

From what I have noticed, unless you are a total fatass, riding does not really affect the battery much at all.  Ive done some stupid riding on my bike, miles at high speeds, outside  temp was low to mid 80's F, got off and immediately felt up the battery pack, motor and inverter to see what I did to it.  All were barely warm to the touch TBH.  I weigh ehh 180 ish Lbs.

Unless the temperature is like 100 degrees out and you are doing fast charge, 90 mph for 50 miles, fast charge - 80 mph I can't see how you'd ever get your batteries into the red zone.  Well unless you were on the track too of course.

ALL packs are going to taper way down towards the end of their charge to give the batteries a chance to actually absorb the charge, and the voltages to settle down to more of a realistic value and not a hyped up because of the charge on it.  This also lets them trickle in the balancing charges to get all the banks evened up.
