I live in Eastern Washington and plugged into my wall connector to recharge. When I came out to the car, which is in the garage, 3 hours later I saw a notice on the dash saying that the wall connector was hot and the charging rate had dropped. I looked at the connector and there was a red light showing in addition to the usual green display. The thermometer in the garage showed 100 degrees. The cable from the connector to the car was hot to the touch. Wanting to avoid problems I immediately turned off charging, thinking I'd resume at night when it got cooler. What I"m wondering about is if there is an automatic overheating disconnect. In other words, will it shut itself off if it gets too hot? Anybody know?
