As an FYI it seems that Rivian really copies Tesla... For their Rivian Adventure Network chargers, which are CCS, they use a ~500kW transformer for 6 stalls. While Tesla normally uses a ~1000kW transformer for 12 V3 stalls. (~83kW/stall if all in use.)
So in the configurations currently being used neither Tesla's nor Rivian's chargers would qualify for NEVI funding.
