Huh, hard to find the page on Tesla's website anymore that explains stall pairing.
Read the numbers on the stalls. You'll see like 1A, 2A, 3A, 1B, 2B, etc. something like that. Each number corresponds to one stack of the charging hardware, and the A and B sides share the power. First car to hook to one of them gets the faster rate, and the second car on the pair gets the rest. As the first car fills and slows down, it will keep shifting power to the second car.
So basically just look for where there are two of the same number that aren't being used, like 3A and 3B and pick one of those. If someone is already on 2B, don't go on 2A if you can avoid it because you would be sharing the charging rate. Make sense?

You can't. It depends on your level of charge, how long you have been driving (the tempature of the battery), the ambient tempature, how busy the supercharger is overall and wether you are paired with someone. The local utilities throttle some stations during peak hours I understand. The charge rate also fluctuates constantly while charging slowing as you fill up. I just sit back and enjoy the free juice.
Pretty much what Rocky said! I never understood why I can be sitting ALONE in a sea of stalls and someone else comes up and decides to plug in right on my DAMN pair!! -_-
I mean come on dude! I guess humans think safety in numbers or something like that but get the hell away from me while charging!! lol

This is the reason why there's a problem with local SpC leachers.. It's anything but free.
That's a problem with Tesla sales staff training. If people don't come on the forum to find out about Supercharger stall pairs, they will never know, because Tesla sales people or delivery specialists never seem to tell any new owners, and they really need to be doing that.
Not all paired stalls are next to each other. It would be nice if there was a standard pairing system. Or numbers placed where they can be seen if there is a car charging. This is also something that will get much worse when M3 is released.
Maybe they want to be paired so that the charging will take longer and they can have more time to eat dinner without the legendary parking fee.
There is. It's always absolutely consistent that A and B are the two shared parts of each number. That is the system. I think you're probably referring to the layout position order of the stalls. It's a little hard to put that horse back in the barn now. That's also a little tough with some that are getting upgraded with additional stalls or a couple that have an odd number of spaces. The letter/number system is always consistent, though.
Yeah, they certainly could use that. It would be nice to have the numbers on the top of the posts where you could see them all instead of down at the bottom where they are hidden by the car in front.
You don't. Yet.
Tesla knows the status of all of the stalls in (near) real time - which ones are damaged, which ones have a paired car that's drawing a lot, which cars are almost done and drawing next to nothing.
I'm hoping (and expecting) that one of these days I'll wake up to find that little yellow alarm clock on the top bar, and the next time I go to a Supercharger it'll recommend a stall, and show me which one it is on a pop-up map of the site.
When several are empty and not degraded, Tesla can use some sort of load leveling algorithm to balance the wear. When everything is shared, it'll point to the one with the highest power available.
Tesla is going to have to be digitizing the sites and setting up a method of picking for the FSDC demonstration at the end of the year anyway - why not include it in a general firmware update as a way to streamline and improve efficiency and decrease the hassle of switching from stall to stall?
This can be tied into an automatic sequencing/reservation system for overloaded sites, too - based on order of arrival, it gives you a "place in line" on the center screen - maybe even an estimated wait time if enough of the cars are running on Nav routings.
Another bonus for Tesla is they can use the same data they use for this to automatically detect and report stalls that have issues.
One challenge will be how this sort of system handles ICE'd stalls. Maybe they give you a button that says "not accessible" or something like that in the pop up, and it gives you another stall recommendation?
If a bunch of folks hit the blocked button on the same stall over a period of time, Tesla can talk to someone about towing...

If you are there first does that slow you down? If so, I'd politely make that an educational moment.

Theory: The stall that operates worst, has the highest internal fraying within the flexible cable -- and therefor, offers the lowest power (and to an extent, the stack of modules in the corral corresponding to the stall/pair needs to be all working). Theory 2: Tesla knows which of stalls works best. Theory 3: If Tesla told everyone to go to the best stall, that one stall soon would be most frayed, and therefore, work indistinguishably (poorly) as the other stalls. So, Tesla telling us, would work for a while, but ultimately become futile.
What causes the theoretical fraying? Moving the cable to plug it in? So going to the reduced power stall and plugging in, then unplugging and moving to another stall would double the fraying, overall.

What? It's not free?
I was sold a car with free Supercharging for life and I haven't been charged yet (2+ years later).
Are you being charged?

In the past, people have proposed lights on the top of the stalls... something like green for full power available, yellow or red for reduced power.
However, the charge you will get depends... battery temperature, state of charge as well as other people charging.
Different contractors lay out the stalls, so some are ABABABAB and some are AAAABBBB. I suspect that even if Tesla told them to do it one way, half the time they would forget to do so.
I've been to many SCs over the past four years and, except for the very few stalls that didn't work at all, I haven't seen any difference that is more than would be caused by the car's SOC when I arrived. The only thing you need to know is if the matching A or B is in use. I do wish that the information was given to the customer at the time of delivery. Even if it was just as a card with SC facts on it. The card would go something like this:
1. SCs are paired 1A to 1B, 2A to 2B, etc. The second car hooked up to a pair will get reduced charge so, when possible, use a stall where the mate is not in use. (plus some illustration).
2. Arriving at an SC with a very low SOC may cause charging to be very slow at first.
3. Be courteous, charge at home whenever possible so others won't have to wait. Leave when charging finishes.
4. The battery life of your car is something we [Tesla] care about, so charging rates may not always be the same for the same SOC.
5. The rate of charge gets slower as the battery fills to protect the battery. Charging enough to get to the next charging location plus some extra just in case, is the fastest way to travel.
6. Some SCs have older (and slower) equipment than others.
7. Sometimes you may find one or more charging stalls blocked by non-Teslas. Don't be a jerk and confront the offender, instead contact Tesla and complain. [my opinion: Enough complaints will get some action. In some cases it's acceptable to complain to the manager of the facility, but most of the time you'll just find the staff there who have no control over anything].
In theory, the second car to connect to a paired stall should not affect the other one that is already charging. Although, obviously this system seems to break down repeatedly which is annoying.
All Tesla would be able to report is the max amps available from a charging cabinet. They don't have real time feedback on "frayedness" of the cables and, even if they did, they wouldn't design their system to take such things into account. It would simply list the max amps available for a given charger pair and it would be up to the driver to follow this guidance.
Not buying it. Assuming that cords inherently wear out based on a number of insertions or thermal cycles (not sure that's true,) I still don't see how not taking action is supposed to help.
If Tesla provides guidance, they can either level the wear so that they all lay the same amount of time and replace a bunch together, or concentrate it into one or two that they replace more often.
There's no advantage to Tesla in not providing guidance and leaving things random, but several advantages to providing guidance, both for equipment management and customer satisfaction
No, it's human nature to gravitate towards others.
CiP: We were in Oxnard 2 weeks ago late at night. Only us and one other X parked at the other end and there's what? 14 or 16 stalls? I pull to the oposite end and the stop sign 1B (remember there is 1A that is spot #1 LOL)
Go and have food at the Lazy Dog. Car gets done 45min later (20 to 95%)... as I'm walking over....
Some dude in a S had to pull into 1A, cut me no room on the pass door.. and this is a EMPTY ROW of stalls!! The X took off from earlier!!
I'm like WTF is wrong with people??And this is not uncommon.
