 蓄(xu)充(chong)不進電是(shi)指發(fa)動機在正(zheng)常工(gong)作的情況下(xia)(xia)，蓄(xu)電池長時(shi)間充(chong)電而電壓上升很(hen)慢(man)。其(qi)原因如下(xia)(xia)：

    1.充電線路中接(jie)線頭(tou)松動(dong)或銹蝕，使電阻增大(da)，電流強度減小。

    2.蓄電(dian)池極板(ban)硫(liu)化，使(shi)其表面附有一層導電(dian)性能差的白色硫(liu)酸鋁(lv)晶粒。這種粗大(da)晶粒堵塞極板(ban)孔隙后(hou)，電(dian)解(jie)液便難以滲入，導致內阻增大(da)，電(dian)流(liu)無法通過。

    3.由于采取(qu)大電(dian)(dian)(dian)(dian)(dian)流給蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)或放電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)解(jie)液(ye)比(bi)(bi)重(zhong)(zhong)(zhong)過(guo)大或液(ye)面高(gao)度(du)不(bu)(bu)(bu)夠等原因，使蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)極板(ban)損壞。診斷(duan)時(shi)(shi)(shi)，先檢查各接線(xian)頭是否松動或銹(xiu)蝕(shi)，然(ran)后(hou)根據充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)的現象(xiang)來(lai)判(pan)斷(duan)極板(ban)是否硫化。若充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)解(jie)液(ye)的溫(wen)度(du)上(shang)升很快，或充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間不(bu)(bu)(bu)長(chang)，電(dian)(dian)(dian)(dian)(dian)解(jie)液(ye)便產生大量氣泡，但電(dian)(dian)(dian)(dian)(dian)壓(ya)并未提(ti)高(gao)，電(dian)(dian)(dian)(dian)(dian)解(jie)液(ye)比(bi)(bi)重(zhong)(zhong)(zhong)也無(wu)明(ming)顯(xian)增(zeng)加，則(ze)說明(ming)極板(ban)已(yi)硫化。當(dang)硫化不(bu)(bu)(bu)嚴重(zhong)(zhong)(zhong)時(shi)(shi)(shi)，可倒出全部電(dian)(dian)(dian)(dian)(dian)解(jie)液(ye)，注入(ru)蒸餾水，然(ran)后(hou)用2安培左右的小電(dian)(dian)(dian)(dian)(dian)流進行長(chang)時(shi)(shi)(shi)間充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，使硫酸(suan)鋁溶解(jie)，但應注意不(bu)(bu)(bu)要讓(rang)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)溫(wen)度(du)升高(gao)。當(dang)電(dian)(dian)(dian)(dian)(dian)解(jie)液(ye)比(bi)(bi)重(zhong)(zhong)(zhong)在(zai)數(shu)小時(shi)(shi)(shi)內不(bu)(bu)(bu)增(zeng)加時(shi)(shi)(shi)，表(biao)明(ming)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)已(yi)充(chong)(chong)足電(dian)(dian)(dian)(dian)(dian)，再進行放電(dian)(dian)(dian)(dian)(dian)。

    經過多次充放電循環(huan)，使(shi)活性物質復原后(hou)，如仍不正常，應更換新(xin)品(pin)。
