Introduction
EV Range Calculator — Estimate driving range from usable battery capacity and efficiency. Enter Usable battery (kWh), Efficiency (kWh/mile) to get an instant, accurate result.
Formula
Range (miles) = usable battery capacity (kWh) / efficiency (kWh per mile).
Step-by-step
- Enter the Usable battery (kWh).
- Enter the Efficiency (kWh/mile).
- Click Calculate to see your result instantly.
Real-world example
Example: With Usable battery (kWh) = 60, Efficiency (kWh/mile) = 0.3, the EV Range Calculator gives a result of 200.
Frequently Asked Questions
What is "usable" battery capacity?
Most EVs reserve a small buffer at the top and bottom of the battery to protect its health, so usable capacity is slightly less than the nameplate total.
Why does my real-world range differ from this estimate?
Efficiency (kWh/mile) varies with speed, temperature, terrain, and driving style — use your vehicle's actual observed efficiency for the most accurate result.
What inputs does the EV Range Calculator need?
You'll need to provide: Usable battery (kWh), Efficiency (kWh/mile). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the EV Range Calculator?
The EV Range Calculator applies the formula exactly as calculated — Range (miles) = usable battery capacity (kWh) / efficiency (kWh per mile). — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the EV Range Calculator free to use?
Yes, the EV Range Calculator is completely free, requires no signup, and runs instantly in your browser.
About the EV Range Calculator
The EV Range Calculator uses a real, verifiable formula — Range (miles) = usable battery capacity (kWh) / efficiency (kWh per mile). — so results are accurate every time, not an approximation.
