Rivian's patent is a no brainer from an engineer's POV. If you want to halve the current, split the parallel battery pack in half, put the halves in series and double the voltage. From the lawyers' POV, however, it is brilliant. Now no other manufacturer can use this obvious technique without paying a licensing fee to Rivian.
The New Rivians will very probably not use this technology.
No worries about waiting absent this or absent special stations for Rivian. One does not charge his 180 kWh battery with 180 kW. Assuming he has made a 200 mile run he will have withdrawn, at worst, 100 kWh and will require 40 minutes to replace that from a 150 kW CCS charger of which there are a few (11 at Albany, NY) at each of the Walmart EA stations. A Tesla owner driving an equally chimerical CT with about the same Wh/mi consumption would charge the same length of time at a 150 kW station. The driver of one of the current model Teslas would charge for around half an hour because his wh/mi are about 3/4 those of the Rivian or CT (at a 150 kW SC).
The "generic" CCS charger is/was a 50 kW unit with one CCS hose and one CHAdeMO. Those are all over rural Quebec (for example). This is changing as the EA project advances. Soon the 150 - 350 kW units will be the generic chargers and the 50 kW units only of interest as a means of "topping off" if you get lowish between the high power units or a wandering about at a leisurely pace.
All this aside, more DC fast chargers are better. The SC network was a tremendous marketing tool for Tesla and it can be one for Rivian as well if they put them at "adventure" sites which is apparently exactly what they are planning to do.
