鋅空氣燃料電池暨鋰電池複合動力UV車能量管理策略之研究與開發

Research and development of energy management strategy for a duel battery electrical utility vehicle

指導教授 : 林秋豐

摘要


論文摘要內容: 本研究主要針對一搭載鋅空氣燃料電池暨鋰電池之純電動車,以並聯式複合作動之架構為基礎,開發出一套能量管理策略,在符合駕駛者目標性能需求下,以達到最大續航力並維持鋰電池最佳壽命為目標來分配電池的輸出。其中,能量管理策略以Rule base邏輯控制法則來設計,主要概念為車輛於低負載需求行駛下,由鋅空氣燃料電池(Zinc-Air Fuel Cell, ZAFC)單獨提供電能,當車輛於中高負載行駛狀態下,則進入複合作動模式,此時鋰電池與鋅空氣燃料電池共同提供電能至馬達,來彌補鋅空氣燃料電池功率不足,以達到駕駛者之需求功率。最後,於怠速之時,鋅空氣燃料電池會於鋰電池殘電量不足時對鋰電池充電,以維持鋰電池之殘電量於一設定的範圍,以增加鋰電池的壽命。模擬結果顯示,透過合理的分配以及鋅空氣燃料電池對鋰電池的充電控制,能夠使電動車達到最大的續航力,並使鋰電池的殘電量維持在目標範圍內。

The contents of abstract in this thesis: The purpose of this research is to develop an energy management strategy for a (Zinc-Air Fuel Cell)ZAFC and Li-ion duel batteries module. The goal is to fulfill the demand from the driver, meanwhile, to maintain the State of Charge (SoC) of the Li battery at a desired level such that all the energy in a journey comes from ZAFC and also the Li battery can have longer cycle life. The energy management strategy is a rule-base strategy, in which, the motor power comes from ZAFC while the demanding power is low. When the demanding power crosses over a threshold, the Li battery compensates the ZAFC to fulfill the demand. While in idling, the ZAFC charges the Li battery to maintain the SoC at a desired level. The charging law is basically a PI controller. Finally, simulations were conducted to evaluate the performance of the energy management strategy. Results show that the energy management strategy can provide satisfactory performance.
