Charging speed on fast charger

[RederOr]

Hi,
I'm just sitting at fast charger (160kW) and the

car pulls approx 50kW only. I thought it will be something like 80 kW (long range). I started from 45% battery. Is it normal ?

most likely yes. As batteries fill up, the charging speed slows down. You might get 80kW when between 10 and 25% perhaps, but unlikely at 50%
Maybe in the future if you could also share the charging curve for the rest of the charge it would be useful.
What was the ambient temperature?
Did you preheat the battery on the way to the fast charger?

Hi,
Ambient was around 11 degC. Specs says I don't have preheat but I turned it in - there is option to turn it on in the options for battery.
No idea how to share to charging curve - can I import it somehow ? Peak power was about 54 kW, then started going down when passed 85% and at 100% it was still showing 6 kW. Car when at 100% showed some message that I can stop charging as it is now only 'topping battery' (don't remember exactly).
I will try to drain it now to 10% and check what happens.

Ambient was around 11 degC.

Peak charge power as per specifications is usually at a cell temperature of around 25 deg C, any lower and your rate will drop..

I just posted the DC charge curve I got yesterday in this thread I opened specifically to post curves ONLY

@RederOr you could have tapped on the image on your phone and the Kempower web app would have shown you the charging curve in real time and also a full report at the end.

Hopefully better luck next time but as you can see from my charging curve yesterday, I was getting >65kW from 50% to 65%.

That was after I had driven the car on the motorway for about an hour on the motorway mostly uphill so would have been warm-ish. Ambient was 12C and very windy but sunny.
