本論文提出二次鋰電池組平衡負載及自負載來描述其充放電行為，此電路模型專注於模擬鋰電池組並聯管理控制，如電池管理系統一樣達到鋰電池組延壽之對策，模型內包含電流檢測、微控制器、LED顯示充、放電燈號等硬體單元。依照二次鋰電池特性的研究上，透過電池自動測量儀器建立鋰電池特性參數，再利用特性方程式曲線擬合測量資料，並且儲存在微控制器裡，來協助微控制器估算出電池電量資訊。
本文模擬電池組多顆電池組並聯平衡控制與無平衡控制之比較，鋰電池組滿充電壓進行不同電流放電，得到不同放電時間數據以及多次充放電累積循環壽命之比較，此實驗結果為減緩電池組容量衰退，減少自負載效應可供未來設計電池組平衡控制參考之依據。

關鍵字：鋰鈷二次電池、微控制器、電路模型、特性方程式、平衡放電。

This paper presents two lithium battery load balance and self-load to describe the discharge behavior, this circuit model focuses on the simulation of lithium batteries in parallel control, achieve the countermeasure of lithium battery life extension of the same as the battery management system, the model contains the current detection, micro controller, LED display, charge discharge lamp number and other hardware unit. According to the research on the two characteristics of the lithium battery, the battery through the automatic measurement of battery parameters, the characteristic equation of curve fitting measurement data, and stored in the micro controller, micro controller to help estimate the battery information.
This paper simulated battery multiple parallel balance control and non-balance control, lithium battery full charge voltage of different discharge current, discharge time and the data obtained in different times of charge and discharge cycle life of the cumulative comparison, the experimental results for slowing down the battery capacity decline, reduce the load effect of basis for future design of battery balance control reference group.
