碩士 === 國立臺北科技大學 === 車輛工程系所 === 97 === The main objective of this thesis is to develop an improved electric scooter, Supportive-Power-System (SPS-hybrid). The most important characteristic in this system is to integrate a generator into the electric scooter. This generator will start when the electric storage of battery is insufficient or the motor continuously consume high power with long time. The generator output will be controlled within the low fuel consumption region and adjusted to the full-time maximum output power in order to bear the power motor needed. And the battery is charged with the residual power provided by generator. Consequently, in this system, the battery life will be extended and the fuel efficiency will be improved. Because the characteristic of battery charge and discharge is non-linear, this study builds a mathematics equation to describe this relationship. In order to understand how the generator and battery actually work, the generator is installed into the electric scooter, and experiment is carried out on the chassis power platform. By comparing the simulation and experimental results, system parameters are revised and control policy is reestablished and optimum rules with higher battery endurance and longer battery life could be developed.
