本文旨在研製應用於5G電信基地台之電池管理系統，系統中利用磷酸鋰鐵電池模組作為儲能裝置，以電池管理系統進行控制與維護，並建置具有削峰填谷之電力調度功能的儲能系統。其次，整體系統是由中央監控模組、高頻開關整流器、磷酸鋰鐵電池模組、過電流監控保護電路，以及電池管理系統所組成，其中，電池管理系統與過電流監控保護電路為確保電池模組操作於安全的工作條件內，以及能夠在異常的情況即時脫離外部連結。再者，系統的主要電力來源為高頻開關整流器與電池模組，前者轉換市電供給至負載與電池模組，而後者於斷電的時段供給負載。然而，傳統基地台發生電力中斷的機率不高，為了提升電池模組的潛在價值，本文分析台電之電價表與基地台電源之負載的關係，針對需量契約容量與夏月時間電價，提出兩種削峰填谷之控制策略，並且分別透過模擬及實測結果進行比較，以驗證所提系統之可行性。

This thesis aims to implement a battery management system (BMS) applied to 5G telecommunication base stations. The overall system is composed of control and supervisory unit (CSU), switch module rectifier (SMR), a lithium iron phosphate battery module as energy storage devices, an overcurrent monitoring protection circuit and BMS which ensure that the battery module is operated in safe working conditions, immediately disconnected in abnormal situations, and also builds an energy storage system for load dispatch to cut peaks and fill valleys. Furthermore, the main power sources of the system are SMR and battery module. The former converts the utility power to the load and the battery module, and the latter supplies the load during the period of power failure. However, due to low probability of power interruption in traditional base stations, in order to increase the potential value of battery modules, this thesis analyzes the relationship between Taipower’s electricity tariff and the load of the base station power. According to the demand contract capacity and the electricity price in summer, two control strategies of peak shaving and valley filling are proposed, and the actual measurement results are compared with simulation to verify the feasibility of the system.
