An investigation on the effective performance area of the electric bicycle with variable key input parameters

摘要

In this paper, we will present the effect of a key input parameter on the motion dynamics, electricity consumption, and timing required for velocity and battery voltage to reach stable status. From the results, the researcher can optimize the effective performance area through analysis of the motor torque, velocity, moving distance, and battery voltage. To achieve this goal, a simulation model was established through MATLAB Simulink software to investigate motion and electricity consumption characteristics. Besides that, to support research results an experiment was conducted on the real road test. The research found that the EB mass increases from 21 kg to 43 kg, electric consumption increased by 0.53%, time to reach stable voltage increased from 14.93 to 18.53 s, and time to reach stable velocity increased from 23.3 to 24.53 s. When the transmission ratio increased from 2.18 to 3.43, electricity consumption increased by 0.54%, and time to reach stable voltage decreased from 17.3 to 14.9 s, and time to reach stable velocity decreased from 16.13 to 13.73 s. Following decrease in the EB's wheel radius from 0.42 m to 0.3 m, electricity consumption decreased by 0.13%, time to reach stable voltage increased from 16.1 to 18.5 s, time to reach stable velocity decreased from 17.5 to 16.1 s. When the frontal area increased from 0.423 m(2) to 1.623 m(2), electricity consumption increased by 0.14%, and the time to reach stable voltage decreased from 17.3 to 14.9 s, time to reach stable velocity decreased from 14.9 to 12.5 s. When the slope ratio increased from 0% to 0.82%, electricity consumption increased by 0.08%, time to reach stable voltage increased from 18.5 to 19.7 s, and time to reach stable velocity increased from 14.9 to 16.1 s.
