Fun! I've done similar, taking a walk around the campus of a University on Sunday (free L2, only one or no other cars on Sunday). These 2 hour limits make no sense to me. I you have a BEV (e.g. BOLT or LEAF), you might need more time to continue on your way. Since BOLT, I rarely charge on the road, almost as if celebrating the freedom of PHEV. I know it's backwards (the whole PHEV transition thing), all I can say is it was a great relief coming back to Clarity.
