- Electricity price: $0.15 per kWh
- Gasoline price: $4 per gallon
- EV battery capacity: 60 kWh
- Gasoline tank capacity: 15 gallons
- EV energy consumption: 25 kWh/100 miles
- Gasoline car fuel efficiency: 30 MPG
Calculations:
1. EV refueling cost per mile:
= Electricity price * (EV energy consumption / 100 miles)
= $0.15 * (25 kWh / 100 miles)
= $0.15 * 0.25
= $0.0375 per mile
2. Gasoline refueling cost per mile:
= Gasoline price * (1 gallon / Gas car fuel efficiency)
= $4 * (1 gallon / 30 MPG)
= $4 * 0.0333
= $0.1333 per mile
3. Cost comparison:
= Gasoline refueling cost per mile / EV refueling cost per mile
= $0.1333 / $0.0375
= 3.56
Conclusion:
Based on these assumptions, it is cheaper to refuel an EV battery than a gasoline tank. The cost of refueling an EV battery per mile is approximately 3.56 times less than the cost of refueling a gasoline tank per mile.
