That's still an astonishing design failure: different ports have different connectors for a reason. Can you imagine a what would have happened if the car charging infrastructure would have used your regular 120/230V plugs? There is zero reason why 480mbps USB-C should exist when we already had 480mbps USB-A, except for misguided designers prioritizing aesthetics over usability.
- jrmg 2mo agoCan you imagine a what would have happened if the car charging infrastructure would have used your regular 120/230V plugs? This isn’t a great example because, on the ‘other side', car chargers also have different size cables between the ‘charger’ (EVSE) and the car, with the same plug used on them all (especially with NACS, which doesn’t even differentiate between AC and DC plugs). They rely on negotiation to tell the car how much power it can draw. No-one complains about this.
- po1nt 2mo agoWe are lucky we don't need to transfer (so much) data over these. Just imagine looking for Gen 2x2 or Gen 2 SuperSpeed charging station.
- asteroidburger 2mo agoNo, we need to transfer a lot of power instead. So those with 800v cars need to be mindful to visit certain charger stations/types over other ones in order to get a fast charge, vs relying on the car to boost it from an older station.
- po1nt 2mo agoJust imagine you would visit such charging station and it would support the fast charge. But only the connector, not the cable.
- sokoloff 2mo agoIn a world following your proposed rules, we’d never get to 480Mbps USB-A, because we already had 4-wire 12Mbps USB-A ports with just D+/D- and power and creating 480Mbps USB-A from that would be “an astonishing design failure: different ports have different connectors for a reason” and not all 12Mbps capable USB-A cables would support the 480Mbps spec.
- jauntywundrkind 2mo agoExcept usb-c will have a baseline level if working even with your very lightweight cheap flexible usb2 60w cable. Adding connectors to obstruct functionality, to make each specific use physically incompatible with every other use, was hell. No thanks. Usb-c rocks, it's flexibility is amazing, and anytime you need a serious business use, good cables are well labelled. This is just yet another HN lightning rod issue where all the very narrowly intolerant particular people come out in hordes, but it's just not really an issue. And everyone else is living much more happily.
- sokoloff 2mo ago> anytime you need a serious business use, good cables are well labelled. Unfortunately, many not-good cables are also labeled similarly as good cables (fraudulently).
- Kirby64 2mo ago> Can you imagine a what would have happened if the car charging infrastructure would have used your regular 120/230V plugs? They largely do. I’m not sure I understand your point? The amount of current pulled by the car in an EV is dictated by the car (equivalent to the PD controller on USB-C) and the amount of current max is indicated by the EVSE (which, is sort of like an emarker). When you plug that EVSE into the wall, there is absolutely nothing telling it how much current it can pull.
- sokoloff 2mo ago"absolutely nothing" is overly strong wording for a plug-in EVSE. The standardization of the receptacles tells how much current is safe to pull. "This receptacle is 50A rated and can supply 40A continuous" is given by the 14-50 receptacle shape.
- Kirby64 2mo agoBut you can buy an EVSE capable of pulling 40 amps and plug it into a 20A rated receptacle. It will happily pull 40 amps until the breaker pops. Most EVSEs that are plug in have adapters to do explicitly this purpose.
