Visited this one twice this past weekend. The SC stall we chose was missing one of the center pins and wouldn't make contact.
On the second visit, someone wrote on the stall "charges really slowly 30 kW". I guess someone got it to work. Upon inspecting many of the other stalls, I noticed that one of the center pin was missing on 3 or 4 of the chargers. I think these pins help guide the plug into the socket on the car so that good contact is made. Not sure how to report issues like this. With a guide pin missing, a horizontal torque on the plug may be enough to lose contact.
