Estimate how far your electric vehicle can travel from its battery capacity, efficiency, and current charge level.
How to Use the EV Range Calculator
Enter your EV's "Battery Capacity (kWh)".
Enter its "Efficiency (km per kWh)" - check your EV's specifications or trip computer for a real-world figure.
Enter your "Current Charge (%)".
Click "Calculate Range" to see your estimated driving range.
Frequently Asked Questions
Check your EV's onboard trip computer, which usually shows an average efficiency figure, or the manufacturer's official specifications. Real-world efficiency varies with driving style, speed, terrain, and climate control use.
Factors like highway speeds, cold weather, air conditioning/heating, and carrying extra load or passengers can all reduce real-world range compared to a fixed average efficiency figure.
While charging to 100% maximizes range for a single trip, many manufacturers recommend routinely charging to around 80-90% to help preserve long-term battery health, reserving 100% charges for longer trips.
