How EV Charging Costs Work
The cost to charge depends on battery capacity, how much charge you add, your electricity rate, and charger efficiency.
Formula
kWh From Wall = Battery kWh x Charge % / Charger Efficiency
Cost = kWh x Electricity Rate
Level 2 home chargers are typically 85-95% efficient.
Ejemplo Resuelto
75 kWh battery, charging 80%, $0.14/kWh, 90% efficiency.
- 01Energy needed = 75 x 80% = 60 kWh to battery
- 02From wall (90% efficiency) = 60 / 0.90 = 66.7 kWh
- 03Cost = 66.7 x $0.14 = $9.33
- 04Monthly (8 charges) = $9.33 x 8 = $74.67
Preguntas Frecuentes
Is it cheaper to charge at home or public stations?
Home charging is typically 50-75% cheaper than public DC fast charging. Home rates average $0.10-$0.20/kWh vs $0.30-$0.60/kWh at public stations.
How long does home charging take?
Level 1 (standard outlet): 24-48 hours for a full charge. Level 2 (240V): 6-12 hours. DC fast charging: 30-60 minutes to 80%.
How does EV cost compare to gas?
At $0.14/kWh, an EV costs about $0.04/mile vs $0.12/mile for a 30 MPG car at $3.50/gallon. EVs are roughly 3x cheaper per mile.
