摘要

本論文為提升電動機車的續航力，並改善電池充電不便的問題，決定使用雙電力增程系統(Dual Power System for Extension, DPSE)，以電動機車現有的動力系統結合氫燃料電池，使其成為有助於增加續航力的雙電力系統。以鋰錳電池為主動力源，以氫燃料電池作為輔助能源，輔助能源可直接使用，也可在車輛閒置時對鋰錳電池進行充電，進而達到增程的效果。
本研究使用自行設計的雙電力增程系統實驗平台進行實驗，同時針對此實驗平台應用LabVIEW軟體設計可作為監控程式的人機介面，並利用資料擷取系統將實驗平台上個元件的類比訊號擷取後，透過人機介面及時監控各元件的運轉數據與輸出效率。藉著平台量測到各元件的電壓、電流，可得到最佳的增程效果。
本研究將電動機車應用氫燃料電池之雙電力增程系統為研究目的，使用之氫燃料電池電壓在14.4V時能提供最佳效率。相較於使用單動力系統，雙電力系統之鋰電池消耗功率減少了77.9kW，約17.44%。馬達轉速在685.55rpm時，可達到94.69%的最佳效率，升壓轉換器之效率為85.76%，燃料電池之效率為31.9%。達到低污染、低噪音、低速性能佳、續航力佳、能源補充環境完整的優勢。

This study is to enhance electric scooter cruising range and improve the inconvenience of battery charging, and decided to use Dual Power System for Extension cruising range (DPSE), using LiMnO2 batteries combined the hydrogen fuel cells, making it will help to increase the cruising range. Using LiMnO2 battery as primary power source and hydrogen fuel cells as auxiliary power, auxiliary power can be used directly, and also can charging for LiMnO2 battery when the electric scooter idles, thus achieving the effect of increased cruising range.
In this study, a self-designed experiment platform of the DPSE was employed for conducting the experiment. Meanwhile, interaction of human-machine interface was monitored through LabVIEW software installed at the platform. In addition, the analog information of the operation data and the output efficiency generated by the various components on the platform were acquired via a data acquisition system. Through the experiment platform, the measured voltage and current of all components, can obtain the best extended range.
This study will apply Dual Power System with hydrogen fuel cell on electric scooter as research purposes. When the voltage of the hydrogen fuel cell is 14.4V, it can provide the optimum efficiency. Compared to using a single power system, Dual Power System reduces the power consumption of the battery by 77.9kW, approximately 15.19mJ and 17.44%. When the motor speed is 685.55rpm, it can reach the best efficiency by 94.69%, the efficiency of the boost converter is 85.76%, and the efficiency of the fuel cell is 31.9%. Thus this study achieve low-pollution, low noise, better low speed performance, better cruising range, and added the energy environmental integrity of advantage.
