Comparing EV’s to Gas Vehicles

Note that weather (particularly temperature) and other factors will affect the assumptions below. Basically the information below indicates that around 35 cents per kWh is the break even point when comparing a “average” EV to an “average” gasoline car @ $3 per gallon @ 28 mpg).

Charging @ 35 cents per kWh (Break even point if Gas is $3 per gallon @ 28 mpg)
65 kWh charge rate per hour (estimated)
$0.35 cost kWh
$22.75 Cost per Hour
3 Miles per kWh
195 Miles of recharge per hour
0.1167 $ Cost per mile
97.5 Miles of recharge per 1/2 hour
11.67 $ Cost per 100 Miles
Note - Reduced EV maintenance cost is estimated at 3 cents
How efficient is your car?

1)
- - Charge rate x mi/kWh/60x.9 x minutes = approximately how many miles added to vehicle based on the charge rate and the efficiency of vehicle. The 0.9 is estimated to include charging losses of 10%+- while charging
2)
- - Remember that your vehicle never charges at the advertised maximum charge rate during the entire session
