Our electric vehicle range calculator helps you estimate how far an EV can travel on a full charge.
The driving range of an EV depends on its battery capacity, energy consumption per kilometer, and the overall efficiency of the vehicle’s powertrain. If you know these values, you can easily calculate the estimated range.
Do you want to know the formula for EV range, its units, and how to compute it step by step?
Are you curious about how factors like battery efficiency and consumption affect real-world driving distance? Look no further because you’ve come to the right place!
🔋 Electric Vehicle Range Calculator
Estimate your EV’s driving range based on battery capacity, efficiency, and consumption.
📘 Formula Explanation
Range (km) = (Battery Capacity (kWh) × 1000 × η) ÷ Consumption (Wh/km)
- Battery Capacity → Size of the EV battery in kWh.
- Consumption → Energy used per km (Wh/km).
- η (Efficiency Factor) → Accounts for system losses (typically 0.85 – 0.95).
📌 Solved Problem Example
An electric vehicle has a battery capacity of 75 kWh and an energy consumption of 150 Wh/km. The system efficiency is η = 0.90. Calculate the estimated driving range.
🧮 Step-by-step Solution
- Step 1 — Convert battery capacity to Wh: 75 kWh × 1000 = 75,000 Wh
- Step 2 — Apply efficiency (usable energy): 75,000 × 0.90 = 67,500 Wh
- Step 3 — Divide usable energy by consumption: 67,500 ÷ 150 = 450 km
Final Answer: Estimated Range = 450 km
If you prefer miles: 450 km × 0.621371 ≈ 279.62 miles.
📚 Reference Table (η = 0.90)
Typical vehicle types with example battery sizes and consumption values. Ranges are computed with the formula above.
| Vehicle Type | Battery (kWh) | Consumption (Wh/km) | η (efficiency) | Estimated Range (km) |
|---|---|---|---|---|
| Small city EV | 22 | 120 | 0.90 | 165.00 |
| Compact hatchback | 40 | 140 | 0.90 | 257.14 |
| Midsize sedan | 60 | 150 | 0.90 | 360.00 |
| Long-range sedan | 75 | 150 | 0.90 | 450.00 |
| Large SUV | 85 | 200 | 0.90 | 382.50 |
| Performance EV | 100 | 250 | 0.90 | 360.00 |
All ranges use the formula: (Battery kWh × 1000 × η) ÷ Consumption (Wh/km). Adjust η and consumption for real-world conditions.
FAQs
What is an electric vehicles range?
Our EV range calculator is a tool to assist in determining how far an electric vehicle will travel on a full charge. It vary with battery size, power consumption and efficiency.
What does EV range indicate?
Multiply a 1000 to the battery capacity, apply the efficiency and divide by consumption. Our calculator will do all the math for you.
What impacts the range potential in real-world driving?
Things such as speed, terrain, temperature, and AC/heater usage can change the range. Efficiency accounts for typical real-world conditions.
