電池部件溫度試驗、電池組表面溫度試驗,除外殼表面溫度要求不同外,都需要求電池組在充電和放電兩種情況下進行溫度測試。
溫度在放電回路的測試,充滿電的電池組以不超過放電過流保護值恒流放電,溫度被監測到熱穩定或放電到規定的放電截止電壓,結束測試。
溫度在充電回路的測試,需用0.2C放電到制造商指定的放電截止電壓的放空電池組。
溫度(du)在充(chong)電(dian)(dian)(dian)(dian)(dian)回路(lu)的(de)測試(shi),放空電(dian)(dian)(dian)(dian)(dian)池需(xu)按恒流(liu)(liu)恒壓充(chong)電(dian)(dian)(dian)(dian)(dian)模(mo)式進(jin)行充(chong)電(dian)(dian)(dian)(dian)(dian),并且最(zui)大(da)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓不能超(chao)過(guo)制造商推薦的(de)最(zui)大(da)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓。測試(shi)中,充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不能超(chao)過(guo)3倍(bei)制造商規定的(de)最(zui)大(da)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)或(huo)充(chong)電(dian)(dian)(dian)(dian)(dian)保護過(guo)流(liu)(liu)值(zhi),溫度(du)被監(jian)控到穩(wen)定,或(huo)電(dian)(dian)(dian)(dian)(dian)池組充(chong)滿電(dian)(dian)(dian)(dian)(dian),結束測試(shi)。
