About this calculator
The Electric Vehicle Consumption Calculator estimates the range of your electric car based on battery capacity (in kWh), current charge level (in percentage), and average consumption (in kWh/100 km). The result is displayed in kilometers, helping you plan trips and recharges more accurately.
The calculation is simple: multiply the total battery capacity by the charge percentage to get the available energy. Then, divide this energy by the average consumption per 100 km and multiply by 100. For example, a 50 kWh battery with 80% charge and consumption of 15 kWh/100 km yields 266.7 km of range.
Use this calculator whenever you need to know how many kilometers your electric vehicle can travel with the current charge. It is useful before long trips, for comparing models, or for understanding the impact of changes in consumption (such as highway driving or cold weather).
Caution: actual range may vary due to factors such as driving style, temperature, use of air conditioning, and terrain type. This calculator provides an estimate based on averages; for greater accuracy, consult your vehicle's specific data and real-world conditions.
Frequently asked questions
What does kWh/100 km mean?
It is the unit of energy consumption of the vehicle, indicating how many kilowatt-hours are needed to travel 100 km. The lower the value, the more efficient the car.
Does the calculator consider charging losses or battery degradation?
No. It uses only the entered values. For more realistic estimates, consider that the usable battery capacity may be lower due to aging and that charging has typical losses of 10% to 20%.
Can I use it for plug-in hybrid vehicles?
Yes, but only for the electric portion. The total range will be the sum of the electric range and the combustion engine range, which is not calculated here.
What is the difference between calculated and actual range?
Actual range is usually 10% to 30% lower than estimated, depending on conditions such as speed, temperature, use of air conditioning, and topography. The calculator serves as an initial reference.
How do I find the average consumption of my vehicle?
Check the owner's manual, the manufacturer's website, or the car's dashboard, which usually displays the average consumption in kWh/100 km. You can also calculate it by dividing the energy used (kWh) by the distance traveled (km) and multiplying by 100.
