Thanks for posting the photo on TMC. I was hoping someone would pick it up from my Twitter feed. Posting a photo to TMC from an iPhone didn't seem like it would be a pleasant experience.
Tesla showed the adapter charging a Roadster from a Coulomb/ChargePoint station at the grand opening for the new charging stations at Bellevue Square in Bellevue, WA.
Despite showing it to the media, Tesla declined to announce the product to owners. I'm not even sure if this is a production unit or a final product, but here's what I was able to learn:
It's apparently 70A capable, so it should work with any J1772 charging station, even the ClipperCreek CS-100. Thus we can get full speed charging from stations that have 70A capability. This will hopefully put an end to needing to try to convince strategically-placed business owners to install a charger that only works for Tesla vehicles.
There's no mechanism for locking either end. The Coulomb charging stations have a way you can lock the plug to the inlet, so that could be a solution. The downside is that it wouldn't be very secure; any lock you can put on that plug could be easily cut. It's also really rude to lock up the plug and prevent other EV drivers from using the charger even after your charge is complete.
Like the hack adapter Cathy and I built, this adapter just passes the wires straight through. Because it pays no attention to the proximity pin, releasing the lock on the J1772 plug does not stop charging, which means you can pull the plug while current is flowing. I have some concerns about the arcing across the contacts that this might cause. I had hoped Tesla would have a solution to this issue.
I'll be more excited when Tesla gets around to telling us about the adapter and the cost, but full J1772 conversion continues to look like the best solution to me.
