dc.description.abstract本論文設計一個以Microchip-PIC單晶片為基礎的鉛酸電池快速充電器,並且採用正負脈衝的充電方式。為快速有效進行充電,有別以往固定脈衝充電時間之方式,本論文則根據電池內部的內阻變化來調整充電脈衝的時間長短,將可使得充電過程更有效率。因此本論文提出內阻的估測方法,在適當的時機進行放電,避免電池充電時的溫昇現象。另外為評估電池所有之電量,則利用模糊理論設計一個估測器,在放電過程中由電池放電時的電壓變化,精確估測出電池的殘電量變化。 為了便於觀測實驗結果,本論文以Visual Basic設計一視窗程式進行監控,並顯示電池的電流、電壓與溫度變化。zh_TW
dc.description.abstractThis thesis presents a PIC-based rapid charger of a Lead-Acid battery. The charger uses Reflex method. However, different form existing methods with fixed charging interval, this thesis proposes a more flexible design with variable charging time according to the internal resistance of the battery. Therefore, this thesis firstly proposes an estimating method of the internal resistance of Lead-Acid battery. To prevent the battery from temperature rising when charging, the charger will discharge when the internal resistance reaches a threshold value. Moreover, for estimating the remaining Coulomb, a fuzzy estimator is proposed by observing the voltage variation of the battery. For the purpose of observing the experimental process, a window display, which shows current, voltage, remaining Coulomb, and temperature, is designed by using Visual Basic.en_US
