本論文針對降昇壓式電池電源模組(Battery Power Module, BPM)並聯架構研擬充電策略，進行充電特性研究。本研究建構一個四組BPM並聯而成的雛型系統，以微處理器作為控制核心，偵測電池電壓、電流與執行充電策略，在使用者設定之充電時間內，充分利用電源供應器可提供之最大功率，依據各電池電量(State-of-Charge, SOC)合理分配充電電流，儘可能達成電池電量平衡的效果。在此BPM並聯組成之電池電源架構下，於充電過程中，可藉由截止開關，將已充飽或依策略需靜置的電池暫時停止運作，亦可將已損壞的電池永久隔離。
本論文將電池電源雛型系統與電腦連結，使用者之人機介面利用Visual Basic設計，可自行輸入充電等級、時間與預算，透過通用非同步接收傳輸模組(Universal Asynchronous Receiver Transmitter, UART)，將訊息傳送給微處理器。此人機介面於充電過程中，可顯示各個電池電壓、電流與電量資訊。經實驗驗證，此電池電源架構配合本研究所提出之充電策略，可充分利用電源供應器功率，達成各項預期功能。

This thesis studies the charging scenario with four buck-boost typed battery power modules (BPMs) which are connected in parallel. A microcontroller is used as the control unit to detected battery voltages and currents to perform the charging scenario. The charging scenario is executed in accordance with the preset charging time, the dc source’s maximum power, and state-of-charges (SOCs) of the batteries to distribute the charging currents. For BPMs connected in parallel, the active power switches can be turned off at any moment during the charging process instead of shutting down the system. By which, the full-charged batteries or the ones suspended by the charging scenario can be temporarily isolated. By the same way, the damaged batteries can also be quarantined and then replaced.
The prototype battery power system adopts Visual Basic to design the user interface. The users’ assignments of the charging power level, the budget and charging time are transmitted through universal asynchronous receiver transmitter (UART) to the microcontroller for scheduling the charging process. During the process, the budget, battery voltages, currents, capacities, the charging time, and the charging power are displayed on the monitor. Experimental results show that charging scenario can achieve the intended functions and fully utilize the power from dc source.
