So we have two problems; max is too low and it tapers off too early. The e-tron tapers at 80%. I would actually prefer 80kW with late taper than 100kW with early taper.
If they both get to 80% or 90% in the same time than I would certainly prefer the 100kW with an earlier taper.
My logic is that when you travel LONG distance you do not allows charge to 80/90%, multiple times I charged to 50%-70% - with 100kW you would be there quicker even if it tapers earlier.
It is quicker (not cheaper) to drive 2x 150km and charge twice from 10% to 60% than to drive 1x 300km and charge once from 10% to 90%.
Arrive at station 1 with 10% SoC:
Option 1: Total time 4hrs 01mins - 64kW charged
Charge in 58 minutes to 90% adding 80% SoC or 64kW (assuming 80kW battery) + 3 minutes for start/stop charge
Drive 300km with 100km/h using 213wh/km arriving 3 hours later with 10% at station 3.
Option 2: Total time 3hrs 44mins - 80kW charged
Charge in 31.5 minutes to 60% adding 50% SoC or 40kW (assuming 80kW battery) + 3 minutes for start/stop charge
Drive 150km with 120km/h with 267wh/km arriving 1hr 15mins later with 10% at station 2.
Adding 5 minutes extra for getting off and on the highway
Charge in 31.5 minutes to 60% adding 50% SoC or 40kW (assuming 80kW battery) + 3 minutes for start/stop charge
Drive 150km with 120km/h with 267wh/km arriving 1hr 15mins later with 10% at station 3.
