Design, Simulation, and Implementation of an Electric Hybrid Motorcycle

This paper presents a general integrated procedure of fabricating a Hybrid Electric Motorcycle (HEM). Firstly, a simple model designed and simulated using ADVISOR2002 and the proposed model is exported to MATLAB/SIMULINK. Secondly, the controller schematic and its optimized control strategy are described. In addition, the ratings of the components including the batteries, electric motor, and internal combustion engine (ICE) are calculated based on the design. A 125 cc ICE motorcycle is selected for conversion to HEM. A brushless DC (BLDC) motor assembled in front wheel as accessory propellant. The nominal powers are 8.2 kW at 8500 rpm and 500 W for the ICE and BLDC respectively. The original motorcycle has a Continues Variable Transmission (CVT) that is the best choice for the HEM power transmission because it can operate in automatic handling mode and has high efficiency. Moreover, by using CVT the ICE can be started while it is running at 15 km/h. Finally, the three operating modes of the HEM, the servo motors, and the LCD panel were explained.Copyright © 2010 by ASME
