The transition from the CCS1 to the Tesla's NACS charging connector is expected to kill the SAE J1772 (AC) plug, because NACS can be used for both AC and DC.

I was wondering with all the talk of NACS, what would happen to J1772. I think I found the answer, unless folks here see it differently. Thanks!

    Actually, it’s not just another plug. The fact that the same Pins are used for AC and DC charging adds a little bit more complexity to the car. Either you need additional switches in the car to separate the Onboard AC-Charger from the charging port, or the AC-Charger must be designed to withstand an DC input on its AC-Input contacts. That probably won’t be the biggest problem when the DC-voltage is just around 400V, as the AC-voltage is not that far away.

    But if you switch to 800V Batteries (which most of the industry is doing), that probably could get more challenging, as the AC-charging-voltage won’t change.

    We‘ll see what the car industries solution will be.
