EV Cost Per Km Calculator
Calculate exact unit electricity expense per kilometer and per 100 km.
Estimate real-world driving range from usable battery capacity and consumption.
Real-world highway driving at 100+ km/h will typically deliver 15%–20% less range than urban stop-and-go driving with regenerative braking.
Multiplies usable traction pack capacity by the vehicle consumption efficiency metric.
Usable Battery Capacity (kWh) = Gross Capacity (kWh) × (Usable Buffer% / 100) Estimated Range (km) = Usable Battery Capacity (kWh) × Efficiency (km/kWh) Estimated Range (miles) = Estimated Range (km) × 0.621371 A 60 kWh gross pack (95% net usable buffer) operating at an efficiency of 6.5 km/kWh.
Gross capacity is the physical total capacity of all cells combined. Net (usable) capacity is the software-accessible portion, with safety buffers reserved at top and bottom to ensure cell longevity.
Standardized test cycles are conducted in controlled lab conditions without headwinds, aggressive acceleration, high-speed aerodynamic drag, or heavy climate control usage.
