本論文探討電池組與降昇壓型轉換器(Buck-Boost Converter) 配置成之電池電源模組(Battery Power Module, BPM)的串並聯放電操作特性。多組BPM之輸出端串聯或並聯，雖受相同輸出電流和電壓之牽制，但仍可個別運作，根據電池電量(State-of-Charge, SOC)、負載需求以及轉換器操作模式，規劃電池之放電電流。本研究針對降昇壓型BPM串聯以及串/並聯兩種架構，分析轉換器操作在連續導通及不連續導通模式時之操作特性，推導電池電流之分配方程式，據以擬訂之放電策略，並進行實驗。實驗結果顯示，降昇壓型BPM串並聯操作，具有很好的電量平衡能力。此外，更可設計容錯機制，不需外加輔助電路即可隔離已損壞或電量耗盡之模組，有助於電池電源模組的維護與管理。

The operation of a battery power bank with buck-boost type battery power modules (BPMs) connected in series and parallel is studied. All BPMs in the power bank are collaboratively to cope with the load requirements under the restraints of a same output current for serial configuration and a same output voltage for parallel configuration. However, the BPMs can substantially be operated individually to schedule the discharged currents from batteries can be in accordance with their state-of-charges (SOCs) and the operating mode of the converters. The operations of BPMs with series and series-parallel configurations are analyzed to derive the current- distribution equations and then to figure out the discharging strategy accordingly. Experimental results demonstrate that excellent performance on discharge equalization can be achieved during the discharging processes. In addition, a fault-tolerance mechanism can be included to isolate those completely exhausted or damaged batteries. These features are helpful to maintenance and management of a battery power system.
