2A/2B always seem to give me a big problem. My car won't charge in 2A at all, while other cars have no problem doing so. When I charge in 2B (100+kw), if another car plugs into 2A, it will stop my session and show a red ring around the plug. I have to restart my session manually to get it going again. This was actually reproduced a couple of times today. Doesn't happen on 1A/1B or 3A/3B. Any ideas? Thanks!
