本論文的目的是設計無人自走車所使用的電源系統。使用串聯 鋰電池當作自走車執行任務時的能量來源，並利用開路電壓法搭配 庫倫積分法監測鋰電池包電量供自走車作為任務調派參考。在自走 車充電站部分，利用主動式功率因數修正器、切換式降壓電路與軟 體數位 PI 控制實現具有高功因、高效率的定電流充電器。充電時， 為了避免串聯電池彼此電壓不平衡將導致使用壽命降低，因此設計 被動式電池平衡電路達到均勻充電的目標。並透過實驗數據驗證此 電源系統的功能及性能。;The purpose of the thesis is to design power system for Automated Guided Vehicle..To use a series of lithium-ion batteries as a source of energy when perform tasks and open circuit voltage with Coulomb Counting Method to monitor lithium-ion batteries pack capacity as a reference to assign tasks. By using Active Power Factor Correction, Switch Mode Buck Converter and digital PI controller to create a constant current charger with high power factor and efficient in Automated Guided Vehicle charging station. To prevent low utility rate from unbalanced voltage of series cells, passive cell balancing circuit could implement same voltage to each cell. In the same time, verify the functionality and performance through experimental experiences
