The Switch From CCS1 To Tesla's NACS Connector Is Expected To Kill The J1772 AC Plug
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!

I expect 10-15 years of dongle hell as we wait for the old cars to reach end-of-life. Then once everything's settled down, battery chemistry improvements will prompt a migration to the MCS connector for faster DC charging.
Though Tesla is claiming "up to 1MW" for the connector. Perhaps 100 kWh in 6 minutes is good enough for the foreseeable future of passenger road vehicles, even if MCS would be ~4X faster.
Tesla is completely full of it with the 1MW claim. Period. Look at their work on MCS and you'll see what's needed for 1MW charging.
Keep in mind, that claim includes the modifications done to the NACS plug to fix the problems with the Tesla plug.
Also, at those power draw rates, the power transmission to the charger becomes the biggest problem, maybe second to heat dissipation.
Still going to have ac charging at homes and parking lots. I think DC charging at gas station like businesses will be common, but the majority of charging will still be done at home.
If passenger cars ever adopted MCS, they could update the standard to carry AC over the big pins, just like NACS.
Though seeing it compared to CCS, perhaps it would be comically expensive for home charging. I guess it's still smaller than a BFG9000.
The way she's eyeing that thing makes me uncomfortable.
