This article introduces a mini EV for urban single drive,
a the car intended to work as conveyance for city workers,
thereby relieving urban traffic pressure, improving traffic congestion and
reducing urban pollution. The paper primarily designs a
electric reversed tricycle and determines its motor and battery parameters, fixes the cockpit installation location by ergonomics, and
finally completes vehicle arrangement. CATIA is mainly used for modeling and ergonomics analysis during the design process.
