碩士 === 國立臺灣科技大學 === 電子工程系 === 96 === In this thesis, the research of the optimal 5-step charging algorithms for lithium batteries and the implementation of the charging circuit are presented. This thesis can be divided into two parts. First, the optimal charge current setting values that achieve the best performance is found, the number of experiments can be minimized by using Taguchi Method and Orthogonal Arrays. Second, a buck converter is used as power stage and PIC18F microcontroller is utilized to realize the algorithms. A human-machine interface is also implemented to monitor the voltage, current and temperature of batteries during charging process.
