1. I thought that the NACS was open to all. Tesla will charge by the kW as always. Tesla will have to supply the software to Ford.Here is the official Ford announcement:
FORD EV CUSTOMERS TO GAIN ACCESS TO 12,000 TESLA SUPERCHARGERS; COMPANY TO ADD NORTH AMERICAN CHARGING STANDARD PORT IN FUTURE EVS
Adapter is supposed to go into production next year.
It is sounding like use of that adapter will be limited to Fords, and that anybody can't just buy the adapter and use it with another brand. So Ford must be paying Tesla something to allow access to the entire Supercharger network to the vehicles that they sell.
2. Now that Ford has broken the ice, expect others to follow.
