# Electric-vehicle range estimate
# Scope: Constant electrical energy per distance; no drive-cycle model.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

energy = 500 Wh
usable = 0.8
consumption = 15 Wh/km

range := energy*usable/consumption [km]

check range target: range >= 20 km

scenario alternative: energy = 400 Wh
