Kuinka laskea EV Home Charging Cost

Mikä on EV Home Charging Cost?

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.

Kaava

cost_per_charge = battery_kwh × electricity_rate ($/kWh); cost_per_mile = cost_per_charge / range_miles
kwh
Battery size (kWh) — Vehicle battery capacity (e.g., 60 kWh)
rate
Electricity rate ($/kWh) — Grid electricity price (typically 0.12–0.18 $/kWh)
range
Range (miles) — Miles per full charge
cost
Cost per charge ($) — Total to fully charge battery

Vaiheittainen opas

  1. 1Energy needed = Battery capacity × (target% − current%) ÷ 100
  2. 2Cost = Energy (kWh) × electricity tariff ($/kWh)
  3. 3Charge time = Energy needed ÷ charger power (kW)
  4. 4Standard home charger: 7.4kW (32A single phase)

Syöte
Tesla Model 3 (75kWh), 20%→80%, $0.30/kWh
Tulos
45kWh added, cost $13.50, ~6h 5min charging
Syöte
Nissan Leaf (40kWh), 10%→100%
Tulos
36kWh, cost $10.80, ~4h 52min
Syöte
Full charge daily, 30kWh needed
Tulos
$9/day = $270/month at $0.30/kWh

Usein kysytyt kysymykset

How much does it cost to charge an EV?

60 kWh battery × $0.14/kWh = $8.40 full charge. At 250 mi range = $0.034/mile fuel cost (vs. gas: $0.10–0.15/mile).

What about charging at home vs. public chargers?

Home (Level 2): cheapest (~$0.12/kWh). Public DC fast chargers: 2–3× more ($0.30+/kWh) but faster.

Is there a federal EV tax credit?

US: up to $7,500 for new EVs (income/price caps apply). Some states add rebates. Check eligibility.
