Electric Vehicle Range Calculator
Calculate your EV range from battery size and efficiency.
Adjust for temperature, speed, and driving style to get a realistic estimate.
An EV’s real-world range depends on battery capacity, energy consumption efficiency, driving conditions, and temperature.
Basic range formula: Range (km) = usable battery capacity (kWh) / energy consumption (kWh/100km) × 100
Usable vs rated capacity: EV batteries reserve 5–15% of capacity as a buffer to protect battery health. A “75 kWh” Tesla Model 3 has ~73 kWh usable. The car will show 0% battery with some reserve remaining.
Real-world consumption (kWh/100 km):
- Small city EV (Nissan Leaf, VW e-Up): 13–16 kWh/100km
- Mid-size EV (Tesla Model 3, VW ID.3): 15–18 kWh/100km
- Large EV / SUV (Tesla Model Y, Audi e-tron): 18–25 kWh/100km
- Performance EV (Porsche Taycan, BMW iX): 22–30 kWh/100km
Temperature effect: Lithium batteries lose efficiency in cold weather. At −10°C, range can fall 30–40%. At +35°C, range drops 5–10% due to AC load. The rated consumption is measured at ~20°C.
Speed effect: Range drops sharply above 100 km/h due to aerodynamic drag (which scales with speed²). At 130 km/h motorway speeds, expect 20–30% less range than the rated WLTP figure.
Worked example: Tesla Model 3 Long Range (75 kWh usable) at 16 kWh/100km: Range = 75 / 16 × 100 = 469 km (close to 576 km WLTP — WLTP is measured under optimal conditions)
