That's interesting. I wonder if they replaced any of those wall chargers at some point. I've had 3 reports that NONE of the Dublin HPWCs work with a Roadster. All three reports were over 2 years ago.
Must have been. Two of the chargers are immediately to the right of the SuperCharger stations, nearest the building. These are the ones referred to on PlugShare, I believe. They were both occupied with Model Ss, but I noticed that one had dealer plates so went inside and inquired about it. One of the sales reps moved it for me, and I charged. He said he'd leave one open for my return trip, since they'd be closed by the time I came through.
The other two are under the car service lane drop-off roof on the other side of the building. All four were the same model. HPWC, 80 amp. They were NOT the model with the side holster for the charging cable
On my return trip this evening, there was indeed one of the Sales slots open (the one next to the one I had used on the first stop), and I added a good 20 miles in about 30 minutes. But the taper kicked in, so I stopped it at about 204 miles Range mode when the charging had dropped below 40 amps, and moved on. Got home with 70-ish Range miles to spare (upper 40's standard), as I didn't have to use the heat or A/C, and I met up with a bit of traffic that slowed me down. The rain wasn't very heavy for the most part, but with the traffic and foggy/wet roads, most had slowed to about 55-60 mph through about half the trip. Crawled along for a short time. The rest was at 65. Overall, I almost broke even between Ideal and Actual miles (even with a 1,000 foot elevation gain at the end), which was unexpectedly good. During the few really wet sections, you could really feel the car slow as it pushed the water out of the way, so the effects of rain can be substantial. I just got lucky with the timing of the trip between squalls.
By the way, I noticed during my first stop that the HPWC Charger + CAN-SR combination behaved the same as the Clipper Creek HCS-40 + CAN-JR. When I hit "stop" on the VDS, the charging stopped, then a moment later, started up again. One time I saw a charging error of some sort flash on the VDS momentarily, then it cleared. My guess is that if I had let the car charge to completion, it would keep restarting the charge briefly over and over again. I didn't play with it on the return. Just pushed stop, then got out and disconnected before it could change its mind.
I'll pull the logs tomorrow and report if there was anything else worthy to report.
