I had a scary situation at the Chandler Fashion Mall Sears DCFC tonight. I stopped by there to get a quick charge to make it back home and the DCFC got stuck at the "Preparing to charge" phase for a long time. I decided to cancel it, but the Stop button on the screen wouldn't work, and the black release button on the CHAdeMO connector wouldn't release because the red light is still on. But a minute later after I tried, I heard the fan from the big transformer in the back of the station stop, and CHAdeMO red light went out and finally allowed me to disconnect.
I proceeded to try the other port, and again, it proceeded through to the "Preparing to charge" phase and got stuck there again. This time, the fan from the big transformer never kicked on, however. So again, I couldn't remove the CHAdeMO connector now no matter what I tried.
So I called the Blink support number and the rep told me to find an emergency red stop button on the DCFC station. I didn't see any, but she insisted that there should be one on it. She said it would allow me to stop and reset the whole thing so that I could release the connector. I swore to her that I didn't see any on the DCFC and she kept insisting that there should be one. So I remember seeing one at the PADT location, but it's not on the DCFC, it's on a post all by itself nearby. So I looked around and couldn't find any similar post in the vincinity. I had to expand my search a bit and finally found one a good 10 feet away from the DCFC to the right of it, against a wall. I pushed it and the whole thing reset and I was finally able to disconnect the CHAdeMO connect from my car.
I'm not thrilled that the Blink rep didn't know better and kept insisting that the red button should be on the DCFC itself. She probably just followed some instruction on a manual that mentions a red emergency stop button without clearly stating that it can be all by itself away from the DCFC.
Anyway, thought I'd relate my experience to Phoenix folks here who may have use of this DCFC location in the future, so they know that the red emergency stop button is not in the vincinity of the DCFC but a bit further to the right of it, in case they need to use it.
