摘要

由於負載是隨間時變動，本文提出一系統以研究鉛酸電池放電的特性，這是因為鉛酸電池的使用容量是會隨著放電電流的不同而有變化。在本文中，以「利用鹵素燈泡的明滅及燈泡的數目來模擬負載變動」以達成上述研究目的，本文是利用圖控軟體LabVIEW來控制系統內負載的變動，藉著此一介面能夠控制變動的快慢，並且透過它的虛擬儀表功能觀察並記錄在變動負載下電池損耗能量的情形。經由本文中所提出的研究過程中發現，無論負載的變動情況是如何的不一致，但其效果皆與以往的固定式負載的放電效果是相覻不遠的，這也進一步證實以往的負載的放電假設是可行且完善的結論，另外藉由本文所設計之控制系統可明確且容易地對負載放電作一有效且合理的監控策略，如此可進步了解電池特性。

Due to the fact that load is changed from time to time, this thesis proposes a system which can be used to measure the characteristics of Lead-acid battery under varying load conditions. The reason of developing such a system is that the capacity of the Lead-acid battery may change under different load conditions. In this thesis, lamps are used to simulate the load. By changing the number of the lamps, the load condition is changed. In order to achieve the objective, LabVIEW is used to control the load. By varying the change rate of the lamps, the capacity of the battery can be measured and recorded. The result of the thesis indicates that the capacity of the batteries maintains at relative constant value no matter how the loads are changed. This indicates that the constant discharge rate can be used to measure the capacity of batteries precisely.
