New to EV charging?
Level 1 uses a standard outlet and adds a few miles per hour. Level 2 (240-V) is the home workhorse for overnight charging. DC fast is for road trips and time-sensitive top-ups. Learn the differences in one page: Charging levels explained.
Quick formulas
Cost per mile = price ÷ (mi/kWh × efficiency). Use 0.90 for home L2 efficiency by default.
Monthly cost ≈ (miles/month ÷ mi/kWh ÷ efficiency) × price.
240-V time ≈ battery kWh ÷ (charger kW × 0.90).
