摘要:	為了將綠色能源模組可靠的運用在行動設備上，本研究開發具備併聯架構之電源管理系統為四處佈建的物聯網設備建構可攜式長效型直接甲醇燃料電池(DMFC)電源，也為大型車輛及電池儲能站建構可以熱插拔的高效能電池交換系統，均具備安全備援能力。為了物聯網應用，將以往追求高電化學反應效率的複雜的主動式精簡成平面型半主動式模組，以利生產、組裝、以及併聯使用。以新研發的電源管理系統協調控制多組並聯的模組來強化發電量、系統穩定性、及環境耐受性。該成果在戶外經過冬季至夏季共完成長達3600小時的壽命測試，其間實際提供最高12W的瞬間輸出，並維持3.3W的平均發電量。其效能符合設計規格。另外，為了將行動型電池系統應用在車輛動力上，務必得顧及方便、安全、可靠、且高能量效率的電池平行掛載與熱插拔的交換應用。我們設計內含電池管理系統的智慧型電池模組以形成併聯的電池電源及其協調控制的網路系統。網路中主控模組會協調各電池模組進行直接連接到電力匯流排上的安全掛載而不需要電壓轉換器，而其他模組都會執行狀態備援而成備用主控，使系統具備容錯性。經過充放電之依序掛載及隨機抽換測試已確認熱插拔抽換皆是安全的。總體電能效率等效於使用轉換效率高達99.2%的電壓轉換器。 ;Promoting green energy in mobile applications, we developed energy management systems of architectural parallelism for a semi-active Direct Methanol Fuel Cell (DMFC) power station of extended life time for Internet of Things (IoT) applications in the field, and, also, for highly energy efficient battery hot swap technology for electric buses and power battery charging and exchange stations. Both of the applications realize the safety backup parallelism in the system for their fault tolerance. For in field IoT applications, the conventional active DMFC with complexity optimized for the best electro chemical efficiency was simplified and optimized into the semi-active module for better production yield, easier assembly, and parallel operations. New battery management system were developed to coordinate the operation of the modules in parallel to scale up power capacity, to enhance power generation stability and its environmental endurance. The prototype survived 3600 hours of continuous outdoor tests throughout a winter and a summer while maintaining an average power output of 3.3W with a maximum 12W of transient load bearing capacity, complying to its design specifications. On the other hand, to increase power capability, intelligent mobile battery packs with new integrated network capable battery management system were developed to allow battery hot swap and convenient, safe, reliable, energy efficient operation in parallelism. In the network of the plugged-in battery packs, the emerged primary pack coordinates the packs, through their control network, the mounting of the packs′ electric bus onto the common power bus directly and safely without voltage converters. Meanwhile, all other packs are the minors synchronizing to the whole network control status and getting ready to assume the primary role in case of any plug-in change and individual pack failure so that system is fault tolerant. The reliability of hot swap was verified through the tests of sequential plug-ins and random exchanges of battery packs. Our energy output efficiency is equivalent to a system of batteries connected together through voltage converters of efficiency as high as 99.2%.
