Quick Charging Stations are not currently compatible with chademo adapters purchased after May 2017. Tesla says they are currently working with charging station companies to enable it to work but provided me with no timeline or alternative. A friends adapter, purchased a little over a year ago, continues to work. Tesla was not forthcoming with much information but it appears to be a software update is needed at chademo quick charge stations for the new but visually the same looking adapter to work. I don't know why or what they changed internally to cause this.
