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.

      Tesla also claimed FSD “this year” for past better part of the decade. In theory you can charge your battery with whatever voltage and/or current you want… dissipating heat on the other hand is a real problem that kills chemistry. Then again, Tesla doesn’t consider spontaneously combusting cars an issue so…

        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.

        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.

          Exactly, proper car manufacturers are recalling their vehicles and sorting the problem out. Tesla pretends there’s no problem and has teams in place to downplay the range issues.

            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

                  I don’t know why something doesn’t exist. No one made it I suppose. And am not scared of the disruptive EVs or anything else but Tesla is well known for shoddy quality and cutting corners from reducing break caliper size, panel alignment, steering wheel falling apart or coming off, wearing tires in few months to doors getting stuck and batteries catching fire.

                  Every other manufacturer you mentioned goes the responsible route and recalls vehicles to fix the issue. In fact Hyndai just had a recall with bad battery. They did the responsible thing and went on to fix it. Tesla issued 0 of such recalls, instead they have teams of people to suppress complaints. They let beta level of software run on their cars endangering thousands of lives with so claimed full self driving to a point they are now under criminal investigation. But nooo, no disabling of killer software.

                  Regular cars catch on fire all the time but circumstances are different. For ICE car to catch on fire fuel has to be leaking somewhere, or at least its vapors. Which also happens. Gas stations catch fire. But with regular maintenance and some rules in place this is minimized. Happens still, but a lot less.

                  With EV, when they catch fire it’s spontaneous and car doesn’t have to be in use and you can’t do maintenance on your battery. It’s epoxied and welded shut. It’s not the same. Also, what else is not the same is ability to douse that fire. With EV it takes a lot more water to a point where sometimes it’s easier to let it burn. This wouldn’t be as scary if Tesla didn’t have electric doors which in some cases you can’t mechanically open and when batteries go bad, doors get stuck. It’s become a meme at this point with YouTube filled with videos instructing you how to break a window or escape burning Tesla.

      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.
