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.

True, but Inter-vehicle could be cool for several things. First is the EV equivalent of jump-start-and-bring-a-can-of-gasoline, an in-the-field recharge for cars that run out before the recharging station or home charger. It would also be useful as a plug for a range-extending spare battery pack on a small trailer. Seems like other potential uses too.

(But no, I'm not liking that Tesla is taking the typical entitled-ass attitude of avoiding all the standards bodies, doing whatever they want, and expecting others to ratify their standard. If it is that good, it should be readily agreed to by the relevant standards bodies.)

This exists: https://news.ycombinator.com/item?id=41975736 But for Lucid, not Teslas. And also more generally as a use of V2L.

That's entirely possible at present. Many electric vehicles can send power out to power appliances. It's called "Vehicle to Load" or "V2L".

And electric vehicles can slow-charge off a wall power socket, so they could get that from V2L. It won't be a common use, but it would work in a pinch to get you enough juice to get to a better charger?

Lucid supports this directly too: https://lucidmotors.com/stories/introducing-rangexchange

<10kw, so not super fast, but I bet most people are really close to the charging station when they run out.

[vaillancourtmax]

I think they meant "across manufacturers".

Sounds like jumper cables.

[duskwuff]

You know what? You're right. That's literally jumper cables.

But no, I don't think Tesla is doing those.

[SideburnsOfDoom]

Tesla vehicles do not currently support V2L or V2G, although many other EV makes do.

But it does seem that Tesla is planning to do those some time:

Honestly that would be awesome. I still dream of autonomous vehicles auto-convoy and link up for efficiency. Just quietly become a train as needed.

Why is it that when describing EV technology, HN people have a tendency to frame it as "imagine if it could, that would be amazing if"

While describing stuff that exists in some form, and usually has existed for years already now.

It's not evenly distributed new tech for sure (1). But maybe it's the false assumption that "if it was anywhere, I'd be among the ones to see it early".
