分段恒流充電控制方法
   充電設備實現分段恒流充電過程控制須設定控制參數，當某一階段恒流充電達到設定的控制參數時，充電機自動停止充電，停歇1min后再以下一個恒流值充電。控制參數可以是時間、電壓和溫度。
   時間參數控制：設定以該恒流充電至可接受電流值的時間，當充電時間達到設定值時，通過定時器使充電機停止充電，結束該階段的恒流充電。定時控制比較容易實現，但是，當電池在恒流充電開始時其荷電狀態不同或電池因容量衰減而其充電可接受電流減小時，恒流充電時間應隨之調整，電池狀態的不確定性使時間參數的確定變得很難，因此，以定時控制不適應分段恒流控制。
    溫度參數控制：設定恒流充電達到可接受電流時的電池溫度上升值，當電池的溫升（或電池與環境的溫差）達到設定值時，控制器使充電機自動停止充電。理論上，開始充電時電池荷電狀態不一樣的情況下，溫度控制均可適應各階段恒流充電結束時的自動停止充電控制。但是，溫度傳感器的準確性和滯后性容易造成電池過充電。因此，溫度參數作為唯一的控制參數也是不宜的。
    電壓參數控制：設定以該恒流充電達到或接近充電可接受電流值的電壓，當電壓達到設定值時，充電機便自動結束本段的恒流充電。電壓參數控制可自適應電池始充電荷電狀態和電池使用過程中充電可接受電流變化，且控制也比較簡單。電壓參數控制的問題是，當電池的性能出現異常變化時，原來設定的電壓控制參數可能會過高而導致電池過充電。

定壓充電階段終止控制方法
    此階段充電電流小，但時間較長，此階段結束, 即為電池達到了完全充電狀態。為使自動終止充電控制安全、可靠，可采用時間、溫度、電流三個參數綜合控制的方案：
     設(she)(she)定(ding)(ding)一個基本的定(ding)(ding)壓充電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)間(jian)，當充電(dian)(dian)(dian)(dian)(dian)(dian)至設(she)(she)定(ding)(ding)的充電(dian)(dian)(dian)(dian)(dian)(dian)的時(shi)(shi)間(jian)時(shi)(shi)，認為(wei)(wei)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)已達到(dao)(dao)了(le)充足電(dian)(dian)(dian)(dian)(dian)(dian)狀態，充電(dian)(dian)(dian)(dian)(dian)(dian)機便自(zi)(zi)動終止充電(dian)(dian)(dian)(dian)(dian)(dian)。未到(dao)(dao)設(she)(she)定(ding)(ding)的充電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)間(jian)，但(dan)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)溫升達到(dao)(dao)設(she)(she)定(ding)(ding)的限(xian)值時(shi)(shi)，充電(dian)(dian)(dian)(dian)(dian)(dian)機自(zi)(zi)動終止充電(dian)(dian)(dian)(dian)(dian)(dian)。未到(dao)(dao)設(she)(she)定(ding)(ding)的充電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)間(jian)，但(dan)充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)已穩定(ding)(ding)在一個較小的值，且2h不變時(shi)(shi)，認為(wei)(wei)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)已充足，充電(dian)(dian)(dian)(dian)(dian)(dian)結束。
