EV Range Calculator — Range and Charging Cost 2026

EV range is calculated by dividing the available battery energy by consumption and multiplying by 100. Formula: range (km) = (capacity × charge level / 100) / consumption (kWh/100km) × 100. For a 60 kWh battery, 18 kWh/100km consumption and full charge the range is about 333 km.

Average EV consumption is about 15–22 kWh/100km. Small city cars use 13–16 kWh/100km, compacts 15–18 kWh/100km, and larger electric SUVs 20–25 kWh/100km. Consumption rises in winter (heating, lower battery efficiency) and on the highway.

The full charging cost depends on battery capacity and energy price. With a 60 kWh battery and a price of PLN 1.10/kWh a full charge costs about PLN 66. Home charging on a night tariff (about PLN 0.70–0.90/kWh) is cheapest; public DC chargers are more expensive (PLN 2–3/kWh).

Range is proportional to the charge level. At 50% charge a 60 kWh battery gives only 30 kWh, which means half the maximum range. Manufacturers recommend charging to 80% daily to protect the battery — then the real range is lower than the catalogue figure.

In winter EV range can fall by 20–40% for several reasons: cabin heating draws energy from the battery, lower temperatures reduce cell efficiency, and tyre rolling resistance rises. Preconditioning the car during charging helps limit losses.

The cost of 100 km is consumption multiplied by the energy price. At 18 kWh/100km and PLN 1.10/kWh it is about PLN 19.80. That is usually 2–3 times cheaper than a combustion car, where 100 km at 7 l consumption and PLN 6.50/l costs about PLN 45.50.

For daily driving charging to 80% is recommended, which extends the life of lithium-ion batteries. Charging to 100% is worthwhile before longer trips. Frequent full charges and deep discharges accelerate cell degradation.

EV range decreases as speed rises due to aerodynamic drag. At 90 km/h consumption is lowest; at 130 km/h it can rise by 30–40%. That is why real highway range is often much lower than the WLTP combined cycle.

WLTP range is the catalogue value from a laboratory test under optimal conditions. Real-world range is usually 10–30% lower, especially in winter or on the highway. The calculator lets you estimate the real range based on your actual energy consumption.

The calculator uses the battery capacity you enter. Over time the battery loses capacity (about 1–2% per year). To account for degradation, enter the current real capacity (State of Health) rather than the nominal value from a new car catalogue.
