I actually had a lengthy conversation about this with the Hyundai folks that were examining our LEAFs a few weeks ago. I mentioned that preparing the car to charge should be as effortless as possible (currently 5 separate steps if your on a timer). I think the most opportune decision to charge/not charge is done at the moment you hit the "Stop" button. The cover release/cap release should be electronic and together on one button AND another cover release/cap release/timer disable should be right next to it. These two button choices should be next to the Stop button and illuminate (in separate colors) after pressing to visually confirm your choice. Then charging would always just be two steps (button, plug in) no matter what choice you make and integrated with the normal shutdown flow. Hyundai took alot of notes on this. Since their new hybrid actually uses a Li-Poly pack, I think these guys are very serious about battery tech cars.
