Unisciti allacomunità  Cost of an overnight charge?  Idaho Power
charges $.0899 per kwh. How do I calculate what the cost is for
a full charge overnight (assuming I needed to charge for 300
miles)? I would love the answer to be 9 or 10 hours x $. 0899
but think that is wishful thinking (and bad math).   There
usually are transmission charges as well.  Volts times Amps =
Watts; Watts divided by 1000 = Kilowatts  When you plug in you
will see the charging rate (volts and amps) on the dashboard.
You will also see the estimated time to charge.  Multiply
Kilowatts times time to get Kilowatt-hours. Multiply this time
$0.0899 to get an approximate cost. Since there are losses in
the system this number should be increased by 10-25%. Maybe
someone else has a better understanding of the losses.  Cerjor-
thank you!  You're going to fill up for 10 bucks and get change
back.  The think that you forgot is to multiply by the kwh you
draw. A 40 amp circuit at 240 volts is 9600 watts, or 9.6 kw.
Run for an hour, it's 9.6 kwh.
