本論文研究磷酸鐵鋰電池之特性，並利用計算內電動勢與內電阻的方式對磷酸鐵鋰電池作電量估測。傳統以電池之內電阻估測電池之電量，但內電阻會因老化而導致估測之誤差。本文不但量測出電池之內電阻，進而計算出電池之內電動勢，以電池之內電動勢與內電阻混合估測電量，提升電量估測之準確性。再以實際之雙向非隔離型充電/放電電路對4顆串聯電池充放電，驗證其電量估測之準確性。並將電池特性、匯流排電壓等參數經由RS232傳遞至人機介面作即時監測。

This thesis explores the characteristics of the lithium iron phosphate battery to estimate the state-of-charge (SOC) using internal electromotive force and internal resistance. Traditionally, the internal resistance of batteries can be used to estimate SOC. However, the internal resistance of the battery is varied with aging and thus causing error of estimation. By combining internal electromotive force and internal resistance methods to estimate the SOC of battery, the accuracy of SOC estimation is improved. A non-isolated bidirectional converter is used to charge/discharge the four series-batteries to verify the accuracy of the proposed estimating method. Also, the voltage of the batteries, the current of the batteries and the voltage of the bus are monitored though using RS232 interface.
