We don't know much about Rivians BMS at this point but I'd guess that they want to charge on average at about 1.1C which means 148 kW for the 135 kWh pack and 198 kWh for the 180 kWh pack.One huge negative right now is that Electrify America is not providing a consistent enough charging experience to quickly charge that massive battery to take advantage of the extended range that comes with the max battery pack.
As I said in an earlier post 100 miles needs about 50 kWh in either truck so if you need 100 miles you'll have to take on that 50 kWh and if the charger is limited to 50 kW (lots of these 50 kW CHAdeMO/CCS stations out there) it's going to take an hour for either truck. Thus even in this worst case there is no disadvantage associated with the bigger battery. Now if the chargers are higher capacity working as they should be the Max would take on the charge needed for 100 mi in 135/180th of the time it would take the Large as the charge rate is 1.1C in either case.
