> The 48V architecture is the optimal long-term choice, requiring ¼ of the current to deliver the same amount of power. Is there a reason why 48V is better long term than going higher like 96V?
48v is probably more common than 96v in general, so more components available already.
Too big/bulky?
Tesla really deserves some kudos for pushing the 48V architecture and the Ethernet-based communication. It drastically simplifies the wiring mess that is in a typical car. And it's not even close. Just watch the teardown of Cybertruck and compare its wiring to something like F150.
What is ethernet bringing to the picture?
I initially thought this was referring to the connector between the charge port on the EV and the charger base station. Had to think for a second and realized it’s the electrical connections between the various components in an EV.
Glad to know I don’t have to carry 200+ dongles in case I buy an EV.

I believe 50V is a safety limit.

> Tesla invites all device suppliers and vehicle manufacturers to join us in this initiative. This is not a standard in the sense that engineers use the term. Tesla is hoping it will be adopted as a standard and since Tesla doesn't appear to want to involve any standards bodies, Tesla appears to only be interested in making these connectors a de-facto standard. In any case, that is not a standard.

I think we should give Tesla the benefit of the doubt for now. Harmful use of patents could cause issues, but this has potential. We will simply see if other companies are interested, and if they are it can go from internal standard to de facto standard to formalized standard.
Earlier quoted context omitted.
The XKCD doesn't really apply here, since intra-vehicle 48v is kind of unexplored, so there aren't multiple competing standards for that in particular. I do agree that this isn't a real open and free standard however. edit: Inter to Intra.
Nitpick: intra -vehicle. Inter-vehicle power would be pretty weird.
> LVCS...is available in industry-standard light blue Is this tongue-in-cheek, or is there a reason manufacturers care about the color?
Light blue is used for 48V.
