10 min charge time: what it would mean
If we're talking about driving 200 miles and charging for 10 minutes before the next
200 miles, that's a tough problem to solve:
Assume 50 mph and 20HP and PERFECT energy conversion (just for sake of argument)
that is: we're only asking 20HP out of the engine to maintain 50mph.
(200 miles / 50 mph) * 20HP * 0.7KW/HP = 56 KW-hrs * 60KW-min/KW-hr = 3360 KW-minutes
That's how much energy we would spend in a 100% efficient conversion.
Now let's replenish the energy store in 10 minutes: 3360 KW-minutes / 10 minutes = 336 KW
from the charging source.
At 110V that's 3KAmps.
That's an interesting number ;) Note that if it only took 2HP to drive us at 50mph, we'd still
be looking at 300 amps at 110V.
