這個(ge)是(shi)由充(chong)電器內部(bu)的(de)電壓檢測電路(lu)控制的(de)，電池充(chong)電的(de)過(guo)程是(shi)一個(ge)先恒(heng)流充(chong)電再恒(heng)壓充(chong)電的(de)過(guo)程設計。
充(chong)電(dian)(dian)(dian)前期電(dian)(dian)(dian)壓(ya)(ya)達不(bu)到(dao)(dao)電(dian)(dian)(dian)池(chi)(chi)額(e)定(ding)電(dian)(dian)(dian)壓(ya)(ya)，此時紅燈(deng)亮；隨著充(chong)電(dian)(dian)(dian)進(jin)行(xing)，電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)量(liang)接近飽(bao)和時，電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)壓(ya)(ya)達到(dao)(dao)額(e)定(ding)電(dian)(dian)(dian)壓(ya)(ya)，電(dian)(dian)(dian)壓(ya)(ya)檢測電(dian)(dian)(dian)路控制綠燈(deng)亮。
