恒溫恒濕環境下電池充放電測試步驟
來(lai)源： bibil.cn 時間：2020-08-18
    環境因素對于蓄電池的影響還是挺大的，有時候哪怕放著不動，高溫環境或者低溫環境都可能會使電池產生故障，所以為了提高蓄電池的性能，廠家會不斷的進行環境可靠性試驗來讓蓄電池在各個環境下更好的使用，恒溫恒濕試驗箱就是蓄電池環境試驗常用的設備之一。

    環境溫度要求(qiu)

    1.環境溫度(du):+15℃~ +35℃
    2.相對(dui)濕(shi)度: 3~60%R.H.
    3.大氣(qi)壓力(li):86kPa~ 106kPa

    恒溫恒濕試驗步驟(zou)

    1.在將(jiang)恒(heng)溫(wen)恒(heng)濕試驗箱溫(wen)度設定為20+5℃的(de)條件下，以(yi)0.2C5A充電(dian)(dian)(dian)，當電(dian)(dian)(dian)池端電(dian)(dian)(dian)壓(ya)達到(dao)充電(dian)(dian)(dian)限制電(dian)(dian)(dian)壓(ya)后,擱置0.5h ~1h,再(zai)以(yi)0.2C5A電(dian)(dian)(dian)流放電(dian)(dian)(dian)到(dao)終止電(dian)(dian)(dian)壓(ya)。
    2.在將恒溫恒濕試驗(yan)(yan)箱(xiang)溫度(du)設定為20+5℃的(de)條件 下，以0.2C5A充(chong)(chong)電(dian)(dian)(dian)，當(dang)電(dian)(dian)(dian)池端電(dian)(dian)(dian)壓達到(dao)充(chong)(chong)電(dian)(dian)(dian)限制電(dian)(dian)(dian)壓時,改為恒壓充(chong)(chong)電(dian)(dian)(dian)，直到(dao)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)小于(yu)(yu)或等于(yu)(yu)0.01C5A,長(chang)充(chong)(chong)電(dian)(dian)(dian)時間不大(da)于(yu)(yu)8h，停止充(chong)(chong)電(dian)(dian)(dian)。( 此(ci)充(chong)(chong)電(dian)(dian)(dian)制式(shi)為檢驗(yan)(yan)的(de)仲裁(cai)充(chong)(chong)電(dian)(dian)(dian)制式(shi))充(chong)(chong)電(dian)(dian)(dian)后擱置0.5 ~ 1h,在將恒溫恒濕試驗(yan)(yan)箱(xiang)溫度(du)設定20+5℃的(de)溫度(du)下以0.2C5A電(dian)(dian)(dian)流(liu)放電(dian)(dian)(dian)到(dao)終止電(dian)(dian)(dian)壓,放電(dian)(dian)(dian)時間不低(di)于(yu)(yu)5h。
    3.在將恒(heng)溫恒(heng)濕試驗箱溫度(du)設(she)定(ding)為(wei)20+5℃的(de)條件 下，以(yi)1C5A充電(dian)(dian)(dian)(dian)，當電(dian)(dian)(dian)(dian)池端電(dian)(dian)(dian)(dian)壓達到充電(dian)(dian)(dian)(dian)限制電(dian)(dian)(dian)(dian)壓時,改為(wei)恒(heng)壓充電(dian)(dian)(dian)(dian)，直(zhi)到充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流小于(yu)(yu)(yu)或等(deng)于(yu)(yu)(yu)0.01C5A，長充電(dian)(dian)(dian)(dian)時間(jian)不(bu)大(da)于(yu)(yu)(yu)8h，停(ting)止充電(dian)(dian)(dian)(dian)。充電(dian)(dian)(dian)(dian)后擱置0.5 ~1h，在20+5℃的(de)溫度(du)下以(yi)1C5A電(dian)(dian)(dian)(dian)流放電(dian)(dian)(dian)(dian)到終止電(dian)(dian)(dian)(dian)壓,放電(dian)(dian)(dian)(dian)時間(jian)不(bu)低于(yu)(yu)(yu)57min。
