目前充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器主要是(shi)三段(duan)式的(de)，依次(ci)為(wei)恒(heng)流(liu)(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)、恒(heng)壓(ya)(ya)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)、浮充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)三個(ge)階段(duan)，俗稱三段(duan)式充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器。開始用(yong)1.8安培充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，電(dian)(dian)(dian)壓(ya)(ya)逐漸升高(gao)，叫(jiao)(jiao)恒(heng)流(liu)(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)；電(dian)(dian)(dian)壓(ya)(ya)到了(le)一(yi)定值叫(jiao)(jiao)恒(heng)壓(ya)(ya)，在40伏(fu)(fu)左右，最高(gao)充(chong)(chong)(chong)(chong)到44伏(fu)(fu)左右，這個(ge)階段(duan)恒(heng)壓(ya)(ya)；最后(hou)一(yi)段(duan)，電(dian)(dian)(dian)壓(ya)(ya)達到44伏(fu)(fu)的(de)時(shi)候開始往下降(jiang)，降(jiang)到保(bao)底點41伏(fu)(fu)，這時(shi)從涓流(liu)(liu)開始充(chong)(chong)(chong)(chong)，用(yong)100毫安小電(dian)(dian)(dian)流(liu)(liu)慢慢充(chong)(chong)(chong)(chong)，最后(hou)一(yi)段(duan)主要是(shi)保(bao)障讓電(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)足，同時(shi)不讓它(ta)過充(chong)(chong)(chong)(chong)，因為(wei)這時(shi)電(dian)(dian)(dian)流(liu)(liu)很(hen)小。而一(yi)些低(di)(di)價位車為(wei)了(le)降(jiang)低(di)(di)生(sheng)產成本，忽略產品質量用(yong)二(er)段(duan)式充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器甚至是(shi)一(yi)段(duan)式充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器。二(er)段(duan)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器沒有涓流(liu)(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，容易過充(chong)(chong)(chong)(chong)，把電(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)成大肚子，導致電(dian)(dian)(dian)池報廢。
