Ok.. here's a what would you do question:
I was at a CHADEMO charging station recently where only one of two charging stations were working. (Note: I was using the J1772 plug beside it)
There was a Tesla M3 plugged into the one working station and it showed 80% charge.
A woman was sitting in the non-working spot and was trying to figure out what to do. She'd been waiting 20 minutes for the M3 owner but no one had shown up. She asked me if I knew what the protocol was. She's a medical worker and was on call and her EV was really low. She had barely enough charge to get home but definitely not enough to get to the hospital of she was called in. Even if she got home it would have taken her a while to get to the point where she had enough to get in to work. She really needed the fast charger.
So what would the right protocol have been (beyond the fact she had planned badly)? Should she have just continued to wait of should she had tried unplugging the M3?
