AOI Motor Calculator

AOI note: this version separates continuous cruise power from peak acceleration power and corrects grade/rolling forces using gravity.

Vehicle & Road Inputs

Vehicle curb mass kg, without passengers Passengers count Mass per passenger kg/person Cargo / payload kg Target speed km/h Road grade percent, not decimal Acceleration time 0 → target speed, sec Drive motors 1, 2, or 4
