摘要

本研究延續針對手輪馬達電動輪椅設計的混合燃料電池電力鏈結構模擬研究，以實際應用為前提改良其電力管理策略與電力鏈結構。混合燃料電池電力鏈使用主要電力裝置為一個額定功率500 W的質子交換膜燃料電池與兩組額定電壓25.6 V、容量10 Ah的磷酸亞鐵鋰離子電池。本研究的電力鏈結構屬於串聯式動力鏈，透過電力管理策略的控制，可以使混合電力鏈滿足需求輸出功率與延長運作時間。實際製作出的電力鏈實驗平台以電子負載機實際測試，電力鏈可確實依照電力管理策略運作，雖然實驗平台上使用能源裝置規格與負載和模擬系統使用的有出入，但實際測試電力鏈中電力狀態的變化趨勢與模擬結果相近。根據模擬系統結果使用電力管理策略電力鏈與常用串聯式電力鏈在相同輸出負載、相同運行時間3400秒，傳統串聯式動力鏈二次電池充電交替次數達135次，使用電力管理策略的電力鏈二次電池充電交替次數為2次，燃料電池輸出也相對穩定。在實驗平台上使用相似的管理策略，在負載、燃料電池功率近乎減半，二次電池總容量為模擬系統2/3的情況下，二次電池交替次數同樣是兩次，燃料電池也是接近恆定輸出。實驗平台的實驗結果可供模擬系統做修正以及測試工作元件，實驗平台設計過程也可供未來延續發展作為參考。

This research continue the research of hybrid powertrain with PEMFC for an electrical wheelchair powered by rim motors. Under the premise of construction in reality, modify and adjust the original powertrain structure and power management strategies. The main electric power devices in hybrid powertrain are a PEMFC system with 500 W nominal power and two Lithium Iron Phosphate battery packs each with 10 Ah capacity and 25.6 V nominal voltage. The structure of designed hybrid powertrain with PEMFC is a kind of series-hybrid fuel cell powertrain. The power management strategies make the powertrain able to meet the requirement of load and prolong the operating time. The test bench is produced and tested with programmable electric load. The operating process is ruled by power management strategies correctly. Even though some components in test bench and load are different to which used in simulation structure, the state variation trend in powertrain is similar to the simulation result. According to the simulation result, the number of charges of traditional series powertrain can reduced by 98% when using designed powertrain structure and power management strategies in the same loading condition. Besides, the fuel cell output power is relatively stable. The characteristic of low number of charges and stable fuel cell output power can be found in test bench experiment result.The powertrain test bench can used to test component, and the process of design can be used as a reference for future related development.
