Can't plug in for a few hours are Grandama's? Even 3-4 hours @ 4mph (120v) can make a difference. Do you set a departure time so the car and batteries are at the optimal temperature? If you charge under 25% I'd expect to charge at 550 miles per hour at a supercharger (again nav there so the car knows to arrive at optimal temperatures), so if you charge around 275 miles I'd expect another 100 miles in 10-11 minutes. If it's bitterly cold I'd expect another 10 minutes or so. Shouldn't take anywhere near 45-60 minutes unless something is seriously wrong.
