Just a note...when you plug the car in outside of your scheduled charging start time, it will connect, turn on, and look like it is charging for about a minute or so, and then shut off. If you look at the real-time charging rate, it is not charging, but just testing the circuit at very low levels. It is not charging the battery, but testing the circuit to make sure it is ready to charge later. Does yours stay on and charge until it is fully charged?
