Tonight I got home late and plugged my car in about 10 minutes after it's scheduled to charge. I figured I had missed the start, so I'd need to manually ask it to start the charge. Instead, as soon as I plugged it in, it said "Charging will start momentarily". This is exactly what I wanted to happen, but I like to know what the parameters are: does plugging in your car 59 minutes late start a charge momentarily? 1:01 late? What are the rules? Is this documented somewhere?
