dc.description.abstractAs liquid petroleum fuels deplete, transportation will shift increasingly to electric propulsion technology. One of the main problems with the current generation electric vehicles is limited range because the batteries do not have the energy storage capacity afforded by liquid hydrocarbons. Maximizing the range of electric vehicle requires a reduction in performance or an increase in cost of the system. The goal of this study is to optimize the range and performance of an electric motorcycle. The driving range of the experimental vehicle is justified by the current consumption rate where higher current rate significantly reduces the battery discharge capacity. The performance of the experimental vehicles is justified based on the efficiency characteristic during vehicle transient testing. Final gear ratio, voltage, and drive cycle are investigated for their effects on the electric motorcycle performance and range. The experimental vehicles were initially tested for steady-state performance on a chassis dynamometer and the studied parameters are analyzed for correlationship to formulate a simulation model in predicting the vehicle transient performance. The experimental vehicles were then tested on chassis dynamometer based on ECER40 at different gear ratio. It was found that at higher gear ratio, the experimental vehicles performed better than in the lower gear ratio. For the experimental vehicle with different voltage system, it was found that higher voltage will results in lower battery current consumption and better efficiency than the vehicle with lower voltage. Well-to-wheel energy and emission analysis shows that electric motorcycle has better overall efficiency and lower CO2 emission compared to a 110cc motorcycles for case study in Malaysia.en_US
