Thanks for the post Sam! Good stuff. I too made my first visit to do my first DC QC at Leith Nissan in Cary/Apex (turns out I didn't have much of a choice--thanks to 4 Volt and 1 Ford Fusion drivers at work taking up the 5 parking spots available for charging at work. I was down to 2 bars (need about 5 to make it home) and despite my leaving notes on their windshields to text me when they moved their vehicles I got absolutely ZERO texts...grrrr! But that's another story).
So I pulled into Leith Nissan having reached Very Low Battery Warning. It did take me several attempts to actually connect the nozzle to the port. I'm still not sure what the correct procedure is. At Leith Nissan the quick charger is located out behind the service area, but there are no markings on the spot to reserve it for EVs. Fortunately it's located in probably the most inconvenient spot, so the spot was open. However, it was really dark in the back corner of the lot and I had trouble seeing what I was doing.
When I plugged in the display said 12% battery (sounds about right) and my initial readings were 100A @ just over 400V. Unfortunately I did not stay and watch it as I wanted to go say hi and thank you to the dealer and talk about the possibility of getting a second LEAF. At any rate, we ended up talking for quite some time and looked at a few cars, so I was not back at my vehicle before it completed. However, I did get my "Charging Stopped" text message so I can time the encounter, although by the time I got back to my car the display was back to its "Welcome" screen so I did not get to see any summary or stats if they had been displayed.
Anyway, my car charged to 80% as well. I believe that the software is fixed to only fast charge to 80% if it's below a certain amount. So it may not even be possible to do a 0-100% charge. Besides, the taper off at the top end is severe enough anyway that it would be wasteful for you to go the last 20% on the quick charge. It's probably just as fast to move the car to an L2 to top it off to 100% if that's what you're going for and free up the QC spot.
My charge session lasted just over an hour (63 minutes) to get from 0-80% (from the in car display, not the QC display, which as I said earlier started out at 12%, and I don't know what the finishing SOC% was). Of course this was slower than expected, but as you noticed I think it tapers off pretty quickly. I wish I had been around at the 30 minute mark to see what the actual SOC was at that time. I think in many cases, I would not necessarily need to charge all the way to 80% when using this QC unit. I would have been fine stopping at 60% for what I needed to make it home, for example. Still, it does go to show you that the manual's stated range of 30-90 minutes is actually accurate! Don't expect it to take only 30 minutes if you need the full charge!
Battery temp wise, I arrived with 4 bars of battery temp. Ambient temp was around 28F. After the quick charge I actually had 5 bars of battery temp, something I have not seen in the past month!
As for the hours of operation of this unit, when I spoke to someone in service (that's who the receptionist forwarded me to when I called to inquire whether it was really working before committing to go out of my way with just enough juice to make it there) told me that the sales dept closed at 7 and it would be available 'til then. I don't know if they de-energize it at 7 (I was actually there after 7, but so was the sales guy I was talking to). If it remains energized, there are no other physical barriers to pulling up and charging, so it would appear to me that it would be 24 hour access. Maybe someone local could check it after hours and see if it remains energized.
The coolest thing is that I got a new DC FC icon on my NAV map now! Cool!
