摘要

本研究主要目的是改善電動機車續航力不足、充電設施不夠完善及充電時間過於冗長之問題。故本研究以市售的電動機車作為實驗車開發平台，使用48V/24Ah鋰錳電池作為主動力源，低功率型200W氫燃料電池為輔助動力源，透過本研究研製的電力與訊號整合系統及氫燃料電池複合電動機車系統，實現雙電力增程系統，增加行駛里程，以提升電動機車的實用性。
本系統使用LabVIEW圖控程式語言與NI cRIO-9074嵌入式監控系統進行整車的訊號量測及控制，分析鋰錳電池、燃料電池及馬達消耗功率的數據，以驗證增程效果，並依據雙電力增程系統的電力狀況及實車驗證，有三種電力模式情況，如單電力模式、雙電力模式以及充電模式。
最後，本氫燃料電池複合電動機車藉由底盤動力計進行電動機車續航性能試驗，發現雙電力模式時，氫燃料電池以全時200W的輔助電力輸出與怠速充電，相較於單電力模式而言，鋰錳電池放電的電壓與殘電量下降的斜率趨於平緩。於定速巡航30km/h實驗中，行駛距離從原本的34km提升至43km，多增加了9km的行駛距離，其增程率約為20%；於變速行駛續航性能實驗中，行駛循環從原本的22次提升至26次，多增加了4次的行駛循環，其增程率約為15%。
本文所發展的低功率型氫燃料電池應用於電動機車之複合動力系統，可提升電動機車的續航力與解決充電不便的問題，而氫燃料電池系統設計為可拆卸式增程器，保有原本電動機車的架構。本系統具有架構簡單、空間配置容易等優點，值得後續研究者加以推廣應用。

The main purpose of this research modifies the shortcoming of electric scooter, including short cruising range, insufficient charging facility, and long charging time. The researchers took advantage of commercially available electric scooter as a development platform for an experimental scooter, using the 48V/24Ah Li-MnO2 battery as a primary power source, while the 200W hydrogen fuel cell as an auxiliary power source. The researchers designed Power and Signal Integration System, and Hydrogen Fuel Cell Hybrid Electric Scooters System to achieve Dual Power Range Extender System. This system can improve mileage as well as enhance the practicability of the electric scooter.
The Dual Power Range Extender System applied the LabVIEW software and NI cRIO-9074 embedded control system to measure the signals and control the scooter as well as analyze the power consumption of Li-MnO2 battery, fuel cell, and hub motor in order to verify the effect of extended range. There was three driving modes for power status of this system, such as single-power mode, dual-power mode and charge mode.
Finally, the experimental scooter carried the electric motorcycles endurance performance test by the chassis dynamometer experiment. The researchers found that when the dual-power mode, the hydrogen fuel cell auxiliary power 200W output to full-time and idle charging , compared to single-power mode is concerned, the voltage drop and the slope of the State of Charge (SOC) for Li-MnO2 battery discharge gently. In the cruise 30kph experiment, driving distance added 9km distance traveled from the original 34km increase to 43km, the extended range rate was about 20%. In the variable speed driving endurance experiment, driving cycle added 4 cycles from the original 22 cycles increase to 26 cycles, the extended range rate was about 15%.
In conclusion, this study developed low-power type of hydrogen fuel cell applying electric scooter of hybrid system. This system was able to enhance electric scooter cruising range and improve the inconvenience of battery charging, and hydrogen fuel cell system designed for removable range extender, retain the original electric scooter architecture. This system had a simple structure and easy configuration space, etc., It was worthy for the follow-up researchers to promote this system.
