Thanks @chrstna4 I wonder how other cars were getting around 62KW with similar models, weather was cold for everyone tonight and similar SOC. I think this supercharger maxes out at 72KW? Maybe I need to get a better sample size from other superchargers before I get paranoid about my battery.

One more thing interesting is when I arrived there were two cars charging, and 6 spots available on the nav, that’s fine. Then when I plugged in, there were 3 cars charging in total, but only 2 spots available on the nav. Phantom SC occupation seems to be a problem.
I don't know if something is seriously wrong with my battery. I have a 2016 Model S-75. I went in this evening at 100 miles range so SOC was ~42%. Max I ever got was 34Kw, hovering around b/w 28 to 34KW. Isn't that way too low?
Did anyone else notice this slow supercharging speed? If not, looks like its my battery and I need to reach out to Tesla service
- I was not sharing charging with anyone (like 1A, 1B, etc)
- I talked to 4 other Tesla owners, each one of them were around 50 to 65Kw similar SOC

Was the battery cold? What had you been doing prior to Supercharging?
A on one side, B on the other.
Sounds like a normal charge rate for the car having been stationary in cool weather with minimal preconditioning prior to plugging in.
I agree, it’s the same reason regenerative braking does not work fully in this cold weather at the start of a drive. That charge rate was almost certainly due to your battery being cold.

Cold temps and higher state of charge will cause “slow” charging. The car basically needs to be at highway speed for like 30+ minutes or city speeds for an hour or so to get the battery up to temp.
With all my scouting trips while this was under construction, I can tell you that the media (usually TuneIn app) in my Model S consistently stopped working on the lower level of the garage. My Verizon phone seemed to be hit or miss, probably good enough to send a text message, but not good enough to surf the internet. That being said, it's very easy to just take the escalator up to the ground level where the phone works like normal. Only takes about 15 seconds as the escalator is right there.
This is definitely the case. I would never contact Tesla service after just one bad supercharging experience. There are so many potential causes. The most likely culprits here are cold battery and new supercharger, both known causes of slow supercharging. FWIW my battery was cold and SOC was well over 50% so I don't have any other data points to offer. I got a slow charge as expected under those conditions.
I meant to mention this earlier. I predict massive confusion especially considering this is a v2 and most of the 3/Y n00bs don't have a clue about pairing. Usually "urinal rules" suffice to avoid pairing, but this is not an intuitive setup.

I charged yesterday (2B) and today (3A) at different pedestals. Both chargers gave me about the same charge at close to the same SOC but I did get more preconditioning today because yesterday I forgot to set the navigation to the charger until about 5 miles out (today it preconditioned for about 15 miles). I didn’t move around to other chargers either day because other people were there and I wasn’t sharing with anyone on the charger I was on.
We charged our Y there a few hours ago after preconditioning the battery and a lengthy 2 hour drive. The Y sustained a charge rate in the mid-140's KW, which is pretty much the max for a version 2 charger like this. Our state of charge at arrival was about 10%.
I'm guessing that in all your cases where you were not able to see the full charge you expected, there were predictable reasons for it. SOC too high, cold battery, being paired with another charging car, having a throttled battery, not having preconditioned long enough, these could all be reasons. There's probably nothing wrong with the output level of these chargers.

Your original post was confusing, it seemed like you were saying the pedestal you pictured was the slow one you used and because of that it wasn't working. As for your slower than expected charge rate, your battery is still cold, 15 minutes of driving and preconditioning isn't nearly enough to get the battery to optimal temperature.
That might just be the way things will be for a city charger (slow charging because the battery didn’t have long enough to warm up) unless someone is in the middle of a road trip or stopping for a charge at the end of one. The 35 minutes it took for me to drive the 15 miles, with preconditioning starting as I pulled out of my driveway, wasn’t enough to get much speed of charge.
Ok, that's good to read. Given all the lower powered charging sessions, I was sort of starting to wonder whether it had actually been an urban supercharger that just used the traditional style pedestals for some weird reason. But that makes it totally conclusive.
