E-Scooter Hill Climb Grade Calculator

Maximum climb grade with dynamic SOC (20–100 %) and voltage sag torque drop at 36 / 48 / 52 V.

WattQuick

Lower voltage = steeper torque drop on hills at low SOC

Estimated current power44%
State of charge50%
Voltage efficiency loss11.3%
Grade (no sag)19.7%
Torque drop under load55.6%
Effective motor power222W
Climb power166W
Min climb speed8km/h
Nominal voltage36V
Motor efficiency75%

Note: Effective climb power = motor W × (SOC/100) × voltage efficiency under load sag. Slide SOC to 20 % to see when hill torque collapses — common cause of 'my scooter won't climb at half battery'.

About E-Scooter Hill Climb Grade Calculator

Grade physics

P = m·g·sin(θ)·v at steady crawl. Burst peaks exceed continuous rating.

SOC & torque

P_eff = P_nom × (SOC/100) × voltage efficiency. At 20 % SOC many 36 V scooters cannot sustain crawl speed on moderate grades.

Note

Planning estimates for e-scooters—verify against manufacturer specs. Small wheels and light packs behave differently from e-bikes.
