本論文提出以四組電池電源模組(Battery Power Module, BPM)串聯組成之電池電源系統。其中，各BPM由一雙向降昇壓式轉換器與一磷酸鋰鐵電池組構成，可獨立控制，共同運轉，滿足負載需求或充電條件。此系統以庫侖電量累積法(Coulomb Counting)線上估測所有電池的電量狀態(State-of-Charge, SOC)與電池健康狀態(State-of-Health, SOH)。本論文提出完全校正程序，使電池依預設之操作條件由滿電量放空或由零電量充飽。若電池之初始電量介於滿電量與零電量間，可將電池放空或充飽以完成部分校正程序。系統可利用完全與部分校正程序檢測出的電池最大可釋放容量更新SOH，提升SOC估測準確度。實驗結果證實，此電池電源系統可提供準確的線上SOC估測，並於運作時達成電池電量平衡。

A laboratory battery power source is set up by four buck-boost type battery power modules (BPMs) with lithium iron phosphate (LiFePO4) batteries. Real-time estimations of batteries' state-of-charges (SOCs) and state-of-healths (SOHs) by the coulomb counting method are possible since the batteries in BPMs can be individually controlled during either charging or discharging cycle. A standard calibration process is proposed to assess a battery’s SOH by deliberately charging or discharging the battery from empty to full or from full to empty with a scheduled profile. On the other hand, partial calibration can be made in the case that the estimation starts from a status neither full nor empty but ends at the point of empty or full. By identifying the maximum charge status with standard or partial calibration, the SOH of battery in BPMs can be updated accordingly, and then the SOCs can be estimated more precisely. Experimental tests are carried out to demonstrate that the battery power system can provide an accurate online indication of batteries’ SOCs achieve charge equalization and at the same time achieve charge equalization .
