An EV home charging cost calculator estimates the electricity cost and time to charge an electric vehicle at home from a given battery level to a target level, using a standard 7.4kW home charger.
- 1Energy needed = Battery capacity × (target% − current%) ÷ 100
- 2Cost = Energy (kWh) × electricity tariff ($/kWh)
- 3Charge time = Energy needed ÷ charger power (kW)
- 4Standard home charger: 7.4kW (32A single phase)
Tesla Model 3 (75kWh), 20%→80%, $0.30/kWh=45kWh added, cost $13.50, ~6h 5min charging
Nissan Leaf (40kWh), 10%→100%=36kWh, cost $10.80, ~4h 52min
Full charge daily, 30kWh needed=$9/day = $270/month at $0.30/kWh
