摘要

地球能源危機以及污染問題，促成電動車輛的發展，其具有高效率、低污染排放的優點，而複合電力的研究則用以延長其行駛里程。本研究針對太陽能車與燃料電池混合動力車這兩台複合電動車輛進行完整的電力系統規劃與能量管理設計，並進行實車或模擬測試。
太陽能車FORMOSUNⅢ是以參加2005年澳洲WSC比賽為目的，使用反向式的能量管理方法，內容包括平均規劃蓄電池SOC消耗、曲線回歸的太陽能發電量預報以及定功率巡航。車上使用16位元微處理器作為中控電腦，在WSC比賽途中使用自動定速巡航。最後獲得第五名的佳績。
台大機械系自2005年開始研究零污染排放車輛，選定使用燃料電池搭配蓄電池作為混合動力的形式。此混合動力車設定使用場合為一般道路有交通號誌停等的路況，其極速、加速性能與爬坡能力都與一般商用車輛相近，兼顧操控性能與燃料效率。車上使用正向式能量管理方法，以SAE J1711規範作為模擬判準。本研究發展出動態調變方法，以燃料電池額定功率加上兩個修正項，SOC回授修正和功率需求修正，動態調整燃料電池輸出功率，使其可以在SAE J1711規定的UDDS與HWFET行車情境擁有良好的燃料效率，並且能夠提供足夠功率來通過US-06行車情境的加速性測試。

The energy crisis and pollution problem of the earth promote the development of electric vehicles, which are well known by high efficiency and low emission. The research of hybrid electric system is used to extend the mileage of electric vehicles. This thesis brings out complete planes of electric system and designs the energy management of two hybrid electric vehicles, a solar racing car and a fuel cell hybrid car. The solar car, FORMOSUNⅢ, has been proven by test drives and the race, WSC, World Solar Challenge. The fuel cell hybrid car has finished MATLAB/Simulink simulation and been compared with a reference case.
FORMOSUNⅢ is designed and built for participating WSC in Australia at 2005. FORMOSUNⅢ adopts backward facing energy management, including equally distribution of battery state of charge, using curve fitting as solar power generation forecast, and constant-power cruising. The on car computer is a 16 bit microcontroller, which realized auto-cruising during the race. FORMOSUNⅢ hit the finish line at the fifth place.
Department of mechanical engineering of National Taiwan University starts the research of zero-emission vehicle at 2005, and picked fuel cell and lithium-polymer battery as the form of hybridization. This fuel cell hybrid car is designed to drive in urban area. The performances of the car, such as maximum speed, acceleration and hill climbing, are similar to those of conventional cars. So the car gives considerations to both driving performances and fuel economy. The fuel cell hybrid car adopts forward facing energy management, and uses the standard, SAE J1711, as the criterion during simulations. This thesis develops dynamic-adjust method, which makes the fuel cell hybrid car have good fuel economy in UDDS and HWFET driving cycles, and also be able to provide sufficient power to pass the accelerating test in US-06 driving cycle.
