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 DC.subject 內阻 zh_TW DC.subject 正負脈衝充電法 zh_TW DC.subject 鉛酸電池 zh_TW DC.subject 殘電量 zh_TW DC.subject Remaining Coulomb en_US DC.subject Internal Resistance en_US DC.subject Reflex Charging Method en_US DC.subject Lead-Acid Battery en_US DC.title 鉛酸電池之快速充電技術研究 zh_TW dc.language.iso zh-TW zh-TW DC.title The Research of Rapid Charging Technology Use in Lead-Acid Battery en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
