I rolled in last night with 0% charge (that was fun). Plugged into.. 5A? The first spot next to the wood enclosure that holds the cabinets. Anyway, I was low enough the heat wouldn't even turn on. The last (and only other) time I came in at 0% I plugged in the supercharger and it immediately jumped up to 116kW and acted normally. This time when I plugged in, it started to supercharge, but only at 1kW. (more on this in a sec)
Often times the SLC staff will use the superchargers for CPO cars that are being prepped for delivery, and there were two CPO's (A red X 90D and silver S 85) plugged in at the superchargers also. You could tell they were CPO's as they had lots of little hand drawn circles with wax pens around the tiny nicks on the exteriors that would be repaired before delivery.
I assume the CPO's had been plugged in long enough to be charged so I tried moving twice to each of the stalls paired with them but still was only getting the 1kW from each plug. Asking inside they said that when you are
really low the battery must get a little trickle charge to equalize the voltage of the pack (or something to that effect) before actual supercharging would kick in. This was different then last time I pulled in with 0% but made sense, there might of been a software change from my last 0% event a year ago or maybe last time I had a little more juice when I arrived even though it said 0% then also. Regardless I waited about 15 minutes getting only 1kW, and sure enough finally the kW jumped up and started to supercharge. At this point I was I believe at 4A or B, I forget which one but I was paired with the Red X CPO.
It jumped up to about 112kW, but then after only a few moments it quickly and rapidly started dropping. When after only about 4 minutes it was already down to 70kW I moved back to 5A (closest to the wood enclosure). It jumped to 115kW, but again started to quickly drop after a minute or two. Again I moved over, just one spot to 5B (or A, not sure, there was one spot between me and the wood enclosure) and this time it jumped to 116kW and stayed there. This spot gave me a proper taper though, so it stayed high until I was at about 40% when it slowly started dropping down normally.
Side note. While I was there the staff was closing down the store for the night, and moving the test drive cars into the little holding area fenced in behind the store. They must have hit the wrong button on a fob inside because both front doors on the red CPO X plugged into the supercharger at 4B (or A) opened automatically but no one came over to move it. After about 5 minutes of the doors being opened I got out of my car to close them.
The red X was at 100% charge according to the dash. (251 miles of range @ 100% if it's your CPO btw, VIN 3458.) It was left overnight plugged into the supercharger that way, along with the silver CPO S 85 (VIN 16493). I have no idea what charge state of the silver 85 was though as it was locked up the whole time.
