I tried my Chademo adapter today for the first time. I plugged in with 153 miles showing and went for a walk around the block. When I arrived back, 37 minutes later, it just ticked over from 256 to to 257 miles (which is the max my car gets on a range charge). Thus, the Chademo added the last 104 miles of charge (40%) of a range charge, in 37 minutes. This is WAY faster than a SuperCharger, which takes 40 minutes to add the last 20% of charge. So it looks like the Chademo charger is charging over spec? I didn't take much notice of the charging speed when I left (I think it may have been 133mi/h), but when I got back it was charging at 125mi/h 402V 38A. Has anybody else experience this?
