I charged my 2012 Leaf on a fast charger today, from 22% to full. The session lasted a full hour, I had to restart after 85%.
The charge started at full blast (46kW) and tapered gradually off from 50% full. Nearing 100% it was down to about 6kW.
When it finally reached 281, power was down to about 4.5kW. I of course expected the SGTE charger to stop.
But it went on for at least another 10 minutes!
Not only did I see 282, but also 283,284,285,286,287 and finally 288. Then the charger finally stopped. Power was down to about 2kW in the last moments.
But it didn't put in a lot of extra energy. I got to accelerate to 65mph and drive a little less than a mile before I was down to 281 again.
Has anybody else tried to fast charge the Leaf to "the bitter end" ?
