1.恒流充電階段
充(chong)電(dian)(dian)器用較(jiao)大的穩定電(dian)(dian)流(liu)進行快速充(chong)電(dian)(dian)，加快充(chong)電(dian)(dian)效率。隨(sui)著電(dian)(dian)池(chi)電(dian)(dian)壓上升，充(chong)電(dian)(dian)電(dian)(dian)壓隨(sui)之上升，以保證穩速充(chong)電(dian)(dian)；
2.恒壓充電階段
當(dang)電(dian)池(chi)電(dian)壓上升到(dao)一(yi)定階段，轉(zhuan)為穩定電(dian)壓與小(xiao)電(dian)流充電(dian)，直到(dao)達到(dao)電(dian)池(chi)額定電(dian)壓
3.浮充(chong)充(chong)電(dian)階段
蓄電(dian)(dian)池(chi)已經基(ji)本充(chong)滿了(le)，充(chong)電(dian)(dian)電(dian)(dian)壓和電(dian)(dian)池(chi)電(dian)(dian)壓基(ji)本持平(ping)，此時降低為浮充(chong)電(dian)(dian)壓與電(dian)(dian)流進行(xing)充(chong)電(dian)(dian)，以縮小每個電(dian)(dian)池(chi)的(de)電(dian)(dian)壓差，避免虛電(dian)(dian)問題。
