充電(dian)(dian)器與開關(guan)電(dian)(dian)源都能(neng)(neng)夠(gou)提供(gong)能(neng)(neng)源供(gong)應，但(dan)其(qi)主要(yao)的(de)區別于它們的(de)工作(zuo)方式不相同，充電(dian)(dian)器在工作(zuo)過(guo)程中(zhong)能(neng)(neng)有(you)效對所提供(gong)的(de)供(gong)電(dian)(dian)電(dian)(dian)壓、電(dian)(dian)流(liu)進行有(you)效的(de)控(kong)制及管(guan)理，其(qi)工作(zuo)特(te)點：恒流(liu)+恒(heng)壓+智能(neng)(neng)充(chong)電(dian)(dian)(dian)管(guan)理、控(kong)制(zhi)方(fang)式(shi)；開關電(dian)(dian)(dian)源在工作過(guo)程(cheng)中對所提供(gong)的電(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)流(liu)是隨設備(bei)的使用(yong)而不斷變化(hua)的，其(qi)主要(yao)因素(su)設備(bei)一個不斷變化(hua)的量(liang)，但(dan)這(zhe)個變化(hua)量(liang)對電(dian)(dian)(dian)流(liu)、電(dian)(dian)(dian)壓(ya)的要(yao)求(qiu)不甚精確，只要(yao)其(qi)總(zong)功率(lv)能(neng)(neng)滿足工作要(yao)求(qiu)即可(ke)，因此(ci)開關電(dian)(dian)(dian)源工作特點：限流(liu)+限(xian)壓工作(zuo)模式，其在參數要(yao)求方面沒(mei)有充電器精(jing)確。
