IOW every .1875/1.44 minutes (7.8 seconds) of charge time will take
you one mile.
.1855 *kWh / 1.44 kW = 7.8 minutes (not seconds) :(
LOL! I *thought* that looked wrong! I shouldn't mess with power after
a bottle of Merlot. ;-)

Hmmm, to deliver 500 kWhr in 8 minutes at 240 V . . .

30 MWmin / 8 min = 3.75 MW instantaneous
