摘要

觀察目前市售電動機車最大的問題在於續航力的不足，而且充電設施不夠多，對於使用上缺乏了實用性，故本研究為提升電動機車的續航力與改善電池充電不便的問題，將氫燃料電池應用於電動機車，使之成為具有雙電力系統的電動機車，主要以鋰電池作為主動力源，低功率型氫燃料電池為輔助動力源，透過本研究所設計的電力與訊號整合系統及監控系統，來實現雙電力增程系統(Dual Power System for Extension, DPES)與提升續航力之目的。
本研究透過實驗平台，以ECE-40之行車型態分別進行單電力與雙電力的比較，搭配資料擷取系統記錄系統的電壓、電流、功率與殘電量等數據，以驗證低功率型燃料電池作為輔助動力源的增程效果，發現本研究的雙電力策略 - 燃料電池以全時滿載100W的輔助動力輸出與怠速充電，相較於單電力模式而言，鋰電池的放電斜率與殘電量斜率趨於平緩，行駛距離也從原本的29.8km提升至37.9km，多增加了8km的行駛距離，其增程率達21%；另外，也具有成本低、系統架構簡單與空間配置容易等優點。

Observation of the current marketed electric scooter the biggest problem is lack of cruising range, and charging facilities are not enough, for the use of the lack of practicality. Therefore, this research is to enhance electric scooter cruising range and improve battery charging inconvenient problem, we used hydrogen fuel cell in electric scooter become a dual power system, the lithium battery as primary power and low power-type hydrogen fuel cell as auxiliary power, through the designed power and signal integration system, and monitoring system, to achieve the Dual Power System for Extension (DPES) and enhance the purpose of cruising range.
In this study, we use the experimental platform and ECE-40 driving cycle to compare respectively single power and dual power, and the data acquisition system can record the system voltage, current, power and SOC data to validate effects of low power-type fuel cell as auxiliary power source for range extended. We found that dual power strategy - a fuel cell auxiliary power output of 100W at full-time full load and when idle to recharge the battery, and compared to single power case, the battery discharge slope and SOC slope tends gentle, driving distance from the original 29.8km increase to 37.9km, added about 8 km distance, and the extended-range rate reached 21%. In addition, it has a low cost, the systems structure simple and space configuration easy.
