是什么 Electric Car Calculator?

▾

An electric car cost calculator compares the total running costs of an EV versus a petrol or diesel car over time, factoring in fuel/electricity costs, road tax, servicing, and potentially depreciation.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

公式

▾

f(x)Range (km) = Battery capacity (kWh) / Efficiency (kWh/km) | Average EV: 15–20 kWh/100km

如何 Electric Car Calculator

▾

1EV fuel cost = Distance / Efficiency (mi/kWh or km/kWh) × Electricity rate
2Petrol cost = Distance / MPG × Fuel price per gallon/litre
3EV typically costs ~3–4× less per mile in energy
4EV servicing typically 30–40% cheaper (no oil changes, fewer brake changes)

例题解析

▾

示例 1

已知:EV: 4 mi/kWh, $0.15/kWh, 12,000 mi/yr vs Petrol: 30 MPG, $3.50/gal

结果:EV fuel: $450/yr; Petrol fuel: $1,400/yr — EV saves $950/yr
