I've had it happpen once where I would have loved to have the Tesla Supercharger as a backup but basically only go juice up just enough to get to my next 1000v charger
The same thing happened to me, but a lot of "once" things are ways of learning lessons so that there won't be a next time. I showed up in Los Angeles and needed a small amount of charge after a few days to get out of the City, after which there would have been plenty of places to charge with no wait. I could have easily spent a few minutes more charging on the way over. I could have gotten up early that morning to find a place to charge off hours, which would have been the one exception so far with the Lucid.
The essence of the problem is that EA has a reliability problem. If they have a station with ten chargers, and one is down, it's easy to call it 90% uptime. But if their app shows that there are two available chargers, one has a broken plug so it can't be used, and the other is L2, then people will show up thinking that there's no wait, making for a very long line. I was at a different station where I missed a free space by a matter of seconds. I waited around, but there were only four chargers there. With Tesla, if there are a dozen chargers at a small Supercharger station, waiting for one of a dozen to leave is not bad. I waited and nobody was moving, so I went to the one that supposedly had two free chargers, and learned my lesson.
It's not just that Tesla is 400V. They don't seem to be in any hurry to upgrade to 1000V. Even the few V4 Superchargers that have been installed in the US have 400V at the back end. The chargers themselves will be able to remain when Tesla upgrades, as opposed to their older stations where the only solution will be changing the equipment.
The other issue is that they had a closed system for many years, as was the case when the Air was designed. Nobody would have designed the car to be backwards compatible with a network that nobody was allowed to use, had cables with the wrong connector and were too short to reach the car.
Lucid had time with the Gravity to get around the problem, and I don't know the details about how they use one of the motors to up the voltage, but they seem to have solved that problem.
I haven't seen anything directly from Lucid about adapters, so if it's online somewhere, somebody please point me to it. If not, does anybody have experience with third party adapters?
