I just tried the Aerovironment CHAdeMO charger in Cannon Beach, OR a few days ago. No go.
I have an Aerovironment fob from about 3 years ago, but I didn't see a need to use other CHAdeMO stations, so I didn't sign up for their $20/month all-you-can-eat plan. I just figured I'd call and activate the stations when I got there.
I called when I got there, asked them to activate the charge, and...nothing happened. I had tried my adapter at another station previously, so I know it works. I tried unplugging/plugging and pressing the Start button several times. The Aerovironment person on the phone was friendly and trying, but even when she tried a remote reboot nothing happened. The station kept showing the "Welcome" screen as if I had done nothing.
We changed our plans and ate dinner at the Wayfarer that night so we could charge at their HPWC while dining, so we made it home fine. But this was still pretty darn annoying given that I waited over 2 years to get the adapter...and when I try it, things don't work. Even worse, Aerovironment charged me $7.50 plus tax despite me not getting a charge. I just called and they said they would "try" to reverse it but I should check to make sure it really happens and call again when it doesn't.
Even if it did work, the whole process of calling, giving name and address and credit card number is really a pain. But it's the only way to do it on a one-off basis; otherwise you have to get their $20/month plan. Tesla really thought through the logistics and made the Superchargers reliable and easy to use.
Has anybody else successfully used an Aerovironment CHAdeMO charger? Were you on the monthly plan with the fob, or just you just activate when you arrived?
[EDIT: dirkh says in another thread that he knows somebody that has charged there successfully, so it likely was just a network issue at the time I was there]
