Charging Cost vs Electricity Rate
EV Charging Costs
Electric vehicles are typically much cheaper to fuel than gasoline cars, especially when charging at home with off-peak rates.
Formula
Energy to Add (kWh) = Battery Size x (Target % - Current %) / 100
Cost = Energy to Add x Electricity Rate
Home charging at $0.13/kWh costs roughly $0.037 per mile (at 3.5 miles/kWh), compared to $0.125/mile for a 28 MPG gas car at $3.50/gallon.
Example Calculation
Charging a 75 kWh battery from 20% to 80% at $0.13/kWh.
- 01Energy to add = 75 x (80 - 20) / 100 = 45 kWh
- 02Cost = 45 x $0.13 = $5.85
- 03Cost per mile = $0.13 / 3.5 = $0.037/mile
