During some recent free time I traced the below Charge Curve provided by BMW and converted over into Excel. This allowed me to pull some more detail information on the the i4 M50 Charge Curve which includes peak charging as well as more info on relationship between the Charging Power and the Battery State of Charge. Below is more detail information on the charging performance of the i4 M50. Please note that these are estimates based on a traced graph.

Specific Charging Power at different State of Charges:
Charging Power of 200+ kW from 7.5% to 21.5% State of Charge
Charging Power of 150+ kW to 37.5% State of Charge
Charging Power of 100+ kW to 54.5% State of Charge
Max Charging Power of 205 kW at 21% State of Charge

Charging Power at specific State of Charges:
At 0% will have Charging Power of 100 kW
At 30% will have Charging Power of 177 kW
At 50% will have Charging Power of 104 kW
At 80% will have Charging Power of 56.5 kW

Thanks for sharing this!

The iX3 has some good charging capabilities when up against the VW ID4, Audi e-tron and MB EQC:

And the i4 seems to be even better than the iX3
