本文為改善電池組並聯操作特性，以升壓式轉換器為基礎，研製電池電源模組(Battery Power Module, BPM)並聯架構。BPM輸出端雖並聯，但各模組可個別運轉，並藉由各模組開關導通率，協調電池電流，提供負載需求。此外，若某組BPM中電池電量耗盡，可關閉該組主動開關，使之隔離，不需停止系統運作，由剩餘模組提供負載所需。文中除分析BPM並聯運轉模式，探討內阻對此架構各模組電池電流互相影響的結果。並討論電路分別操作於連續導通模式、不連續導通模式與及混合模式之各模組電池電壓、開關導通率對各模組電池電流分配比例。根據理論分析結果，依照電池電壓的高低，可決定各電池供電至負載的比例，擬定平衡放電策略。本研究使用三組並聯之升壓式BPM，配合平衡放電策略，驗證BPM並聯架構與平衡放電策略的可行性。

To improve the parallel operation characteristics of batteries, this research attempts to configure a battery power source with boost-type battery power modules (BPMs) connected in parallel. The discharging currents of the batteries in BPMs can be individually controlled but are coordinated to execute a full amount load current. An additional benefit for the parallel configuration is the inherent fault tolerance, by which the BPMs with completely exhausted or damaged batteries can be isolated without interrupting the system operation.
In this thesis, the operation of paralleled BPMs for both continuous conduction mode (CCM) and discontinuous conduction mode (DCM) are discussed. The analyzed results indicate that the intrinsic internal resistances of the BPMs may alleviate the interaction. A balanced discharging strategy is proposed to discharge the batteries by scheduling the battery currents in accordance with the measured battery voltages. The experiments are carried out on three boost-type BPMs in parallel to confirm the theoretical analyses and to demonstrate the feasibility of balanced discharging.
