本文針對鉛酸電池，提出改良型安時累計法，估測電量狀態。此方法利用放電深度作為估測健康狀態之準則，發展能同時估測電量及健康狀態之估測方法。不同的放電電流不但會造成不同程度損耗，而且以較大電流放電時，即使已經放至截止電壓，但內部仍有剩餘電量未被釋出。有鑒於此，將上述兩個因素加入評估考量，並利用電池放電終了時之最大可釋出電量再次評估健康狀態，以提升估測剩餘電量的準確度。最後，透過實驗測試模擬實際操作環境，根據實驗結果得知最大估測誤差小於6 %。

This thesis proposes an enhanced ampere-hour counting method based on the depth-of-discharge (DOD) to estimate the state-of-charge (SOC) and state-of-health (SOH) for lead-acid batteries. Not only the losses at different discharging currents, but also the releasable capacity at the exhausted state caused by the larger discharging current are considered and compensated. Furthermore, the SOH is revaluated at the exhausted state by the maximum releasable capacity, consequently leading to more accurate SOC estimation. Through the experiments that emulate practical operations, the experimental results reveal that the maximum error is less than 6 %.
