I had my first charging error last night. We were stopping at a local grocery chain with charging stations, and my housemate mentioned that she'd had trouble with one of the stations stopping charging after she plugged in her PIP. I rather foolishly tried the same station, and when I saw her holding the plug's trigger down as she plugged it in, I assumed that she had been leaving it ajar in the port, and that that was the issue. Nope. When we came back out, my car wasn't charging (and had added no charge) and when started, I got the yellow EV with exclamation point symbol. I drove home cursing, and plugged in at our L-1 station. It charged normally there, and when I started the car today, there were no warnings showing. I'll have to try it at another L-2 station, and hope that my car's charging system wasn't damaged...
