As somebody pointed out earlier, the electricity would have to be transferred at a huge rate (i.e., very high current) for this 5-minute "Quickcharge." Let's say it takes 10 hours for that 500 mile trip, and it takes 50 HP to propel the car at 50 mph. (This may be a bit high for a small car.) So this is 500 HP-HR worth of work, or about 372 Kilowatt-hours, or 37,000 amps at 120 v for 5 minutes!
The article mentions that they cannot use an ordinary wall outlet. (It would melt; most are rated at only 15 or 25 amps!) Also that the capacitors operate at very high voltage. So maybe the electric power is transferred from some "accumulator" (perhaps another big capacitor, which is being charged up in the garage out of your wall outlet or a 240-v circuit direct from the meter while you're out driving) at higher voltage, which allows for proportionally lower current.
Or, one could have two capacitors and swap out the discharged one with the one that's been charging for the last ten hours. (Easier said than done, especially if they're large physically.)
