本論文旨在建構應用於控制器區域網路(CAN bus)架構之電池電源模組(Battery Power Module, BPM)，並針對故障的BPM，透過故障隔離控制進行切離，使其他模組仍可正常運作。將電池與雙向的直流轉換器組成BPM，利用雙向轉換器控制各個模組，穩定BPM的端電壓。主控端經由CAN bus發送充放電控制信號至BPM，若BPM故障時，隔離開關可以將故障的模組切離，並藉由CAN bus介面通知其他BPM，改變模組端的電壓與電流，讓系統能夠繼續充電或放電。本研究藉由調整脈波之導通率控制雙向轉換器功率開關的切換，以控制其輸出電壓、充電電壓與充電電流，並利用CAN bus作為主控端與各BPM間的通訊介面。最後實際建構出應用於CAN bus架構之電池電源模組系統，以驗證BPM充放電控制與故障隔離控制之可行性。

The purpose of this thesis is to construct the battery power module (BPM) based on the controller area network bus (CAN bus). The faulty BPM is isolated through the fault isolation control, so that other modules can still operate properly. The battery and the bidirectional DC-DC converter composed the BPM. The bidirectional converter is used to control each module to stabilize the terminal voltage of the BPM. Master transmits the charging and discharging control signal to the BPM via the CAN bus. If the BPM faults, the isolation switch can isolate the faulty module and notify other BPMs through the CAN bus interface to change the voltage and current of the module, so that the system can continue to charge or discharge. In this study, the switching of the bidirectional converter power switch is controlled by adjusting the duty cycle of the pulse signal to control the output voltage, charging voltage and charging current. The CAN bus is used as the communication interface between the monitoring terminal and each BPM. Finally, the battery power module system based on the CAN bus is constructed to verify the feasibility of BPM charging/discharging control and fault isolation control.
