I use CHAdeMO frequently, but have never been able to go much past 80% SOC in a single session, unlike the LEAFs that regularly camp out for a 100% charge on Blink DCFC stations. Given Joe's discovery, I'll take the time sometime soon to wait around and watch to see if the disconnect happens when amps fall to 5 or less.
Among the litany of Blink shortcomings, I have noticed that the second head is no longer reliable. They designed the stations to allow a second car to plug in and order up a charge that would commence as soon as the first car finishes. That has failed the last few times I've tried, meaning that I have to swipe my card and go through the touchscreen menu again.
