How it's calculated
Usable energy = battery kWh × usable share × battery health. Most EVs keep a buffer at the top and bottom, so 85–95 % of the label is usable, and an older battery holds less.
Consumption (Wh/km) starts from your vehicle's typical figure — about 25–35 Wh/km for an e-scooter, 50–70 for an e-rickshaw/L5 3-wheeler, 120–160 for a car — and is adjusted: highway speed ×1.2 (air drag rises with the square of speed), city ×0.95 (regenerative braking helps), AC ×1.12, full load ×1.08, cold weather ×1.15.
Range (km) = usable Wh ÷ adjusted Wh/km. The adjustment factors are averages from published fleet and test data; your own trip computer's Wh/km is the best input.
Results are engineering estimates for planning and learning. Check them against datasheets, supplier quotes and the applicable standards before you build or invest.
Frequently asked questions
Why is my EV's real range lower than the company's claim?
Claimed range in India is tested on the MIDC/IDC cycle at low average speed with no AC. Higher speeds, AC, passengers, hills and hard acceleration all raise Wh/km. Real range is typically 20–35 % below the claim.
What is Wh/km?
Watt-hours used per kilometre — the EV equivalent of km per litre, but lower is better. A 3 kWh scooter using 30 Wh/km goes about 100 km.
Does fast charging reduce range?
Not directly. Frequent DC fast charging and keeping the battery at 100 % can speed up degradation over years, which reduces range gradually. Set battery health below 100 % to see the effect.
