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.

        What is this spontaneous combustion FUD?

        Currently kia and Hyundai owners are currently being told not to park their cars in the garage as they are recalled for catching on fire, but somehow it’s Tesla that doesn’t care about burnimg cars.

            How about what’s actually happening: Tesla does not have a problem with cars catching on fire but the media reports on it every time one does catch on fire and you’re using the accessibility heuristic.

            It used to be that there were dozens of news stories titled “car catches in fire” that used to be titled “Tesla catches fire” because the writee misidentified the make.

                Where are the kia-fire and Hyundai-fire web sites that only report news sources?

                Oh, there aren’t any. Why? Because a regular car catching fire isn’t a news story that “drives engagement”. “Be scared of the disruptive EVs”, however, does.

                FUD

        In the future, cars might store energy in nanosupercapacitors, but we’ll still be stuck with NACS. The ultimate physical limits of the connector are what matters today.

      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.
