摘要

本研究之主要目的為完成『Boston電池管理系統』之研製，此系統由降壓轉換器、PWM產生電路與Boston電池所構成；其主要目的是依據充電中的Boston電池狀態來改變充電形式，使電池不過度充電而縮短了電池可使用的壽命。本系統採用降壓型直流轉換器並使用TL494與PC923兩種功能性IC所做出的PWM電路，來對系統的充電控制。最後，本研究實際研製一套Boston電池管理系統來對電池進行充電管理。

This thesis presents design and development of a Boston battery management system. The proposed system consists of a buck converter PWM generation circuit and the Boston battery. Its main purpose is based on the charge state of the battery to change Boston charging operation in order to prevent overcharging of the battery and shorten the cycle life of the Boston battery. A buck converter associated with PWM circuit which is made up of two functional IC TL494 and PC923 to the system charge control. Finally, the Boston battery management system has been implemented to verify that this system has the capability of charging the battery management.
