Formula
Alcance_elétrico = bateria_kWh / consumo_kWh_km; custo = km_elét × tarifa + km_gás × cons × preço
About this calculator
The Plug-in Hybrid Calculator estimates the operating cost and electric range of your vehicle. You input battery capacity (kWh), electric consumption (kWh/km), electricity tariff (R$/kWh), gasoline consumption (km/L), gasoline price (R$/L), and distances traveled in electric and gasoline modes. Based on this data, the tool calculates how many kilometers you can drive solely on battery and the total trip cost.
The calculation is straightforward: first, electric range is obtained by dividing battery capacity by electric consumption. Then, total cost is the sum of electricity cost (electric kilometers times tariff) and gasoline cost (gasoline kilometers divided by consumption times fuel price). The result shows cost per kilometer and total spent, allowing comparison with a conventional vehicle.
Use this calculator to plan trips, decide whether to charge at home or at work, or compare different plug-in hybrids. It is also useful for those considering buying a hybrid electric car and wanting to estimate monthly savings. Remember that consumption values can vary with driving style, terrain, and air conditioning use.
Cautions: the consumption figures should be realistic, based on the vehicle manual or your own measurements. The electricity tariff considered is residential; charging stations may have different prices. The calculation does not include maintenance, depreciation, or taxes. For a complete analysis, also consider the cost of installing a home charger.
Frequently asked questions
What is a plug-in hybrid vehicle?
It is a car that combines a rechargeable electric motor (plugged into an outlet) with a gasoline engine, allowing part of the trip to be driven solely on electricity.
How do I find my car's electric consumption?
Check the owner's manual or manufacturer's website. It is usually given in kWh/100 km; divide by 100 to get kWh/km.
Does the calculator consider public charging stations?
No. It uses the residential tariff you enter. For public stations, manually adjust the tariff value.
Why is my actual electric range lower than calculated?
Factors like cold weather, air conditioning, electrical accessories, and aggressive driving reduce efficiency. The calculation is an ideal estimate.
Can I use it to compare with a gasoline car?
Yes. Just set electric km to zero and enter the gasoline car's consumption. The total cost will be only gasoline.
