I supercharged at Vacaville, CA yesterday evening and set the limit to 100% since I was going to have dinner while charging -- and before you ask, I did go out there about 40 min later (at 90%) to check that there were other spots available, just to make sure I wasn't preventing others from charging. There were 4 (half the SpC stalls), so I proceeded to 100%. Upon getting back in the car, it was still around 99% and 249 rated miles, so I waited a few minutes to observe what would happen. After 2 more miles were added to the rated range, it looked like battery capacity hit 100%, and the time remaining changed from 5 minutes to "Calculating time remaining..." indefinitely. The interesting part is that, while the voltage stayed around 400V, the current then started bouncing around quickly between 11 and 22 Amps -- something I had never observed before. I took a short video to demonstrate how fast this was occurring (see below). Is this battery balancing at work? If so, why does the current change so dynamically?
