Formula and methodology
Formula: Usable energy = battery energy × efficiency × (1−reserve); range = usable energy/consumption.
The estimate makes energy losses and a reserve policy visible instead of assuming a universal riding range.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Battery energy — Wh; minimum 1.0E-6; maximum 1000000
- Usable efficiency — %; minimum 1.0E-6; maximum 100
- Reserved energy — %; minimum 0; maximum 99.999999
- Energy consumption — Wh/km; minimum 1.0E-6; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Battery energy | 500 |
| Usable efficiency | 85 |
| Reserved energy | 15 |
| Energy consumption | 15 |
Usable energy = 361.25 Wh; range ≈ 24.083 km.
Assumptions and limits
- Energy inputs use watt-hours and consumption uses watt-hours per kilometre.
- Efficiency and reserve are constant planning percentages.
- Rider mass, assist mode, terrain, wind, temperature, tire pressure, battery age, and safety limits are not modeled.
