電源適配器和(he)充(chong)電(dian)(dian)器在我(wo)們的(de)(de)生活中都(dou)十分常見(jian)，都(dou)是(shi)充(chong)電(dian)(dian)的(de)(de)輔(fu)助設(she)備。但是(shi)電(dian)(dian)源適配器和(he)充(chong)電(dian)(dian)器是(shi)什么(me)?有什么(me)區別(bie)和(he)關(guan)系?這些你都(dou)了(le)解嗎?今(jin)天我(wo)們一(yi)起來看一(yi)下。

　　一、充電器

　　充電(dian)(dian)器:英(ying)文名稱Charger，通常指的(de)(de)是一種(zhong)將交流(liu)(liu)電(dian)(dian)轉換(huan)為低壓直流(liu)(liu)電(dian)(dian)的(de)(de)設備，充電(dian)(dian)器是給可充電(dian)(dian)電(dian)(dian)池用的(de)(de)專用直流(liu)(liu)電(dian)(dian)源(yuan)，它內部包(bao)括了限流(liu)(liu)，限壓等滿(man)足(zu)充電(dian)(dian)特(te)性(xing)的(de)(de)控制電(dian)(dian)路。

　　充電(dian)器在各個領域(yu)用途廣泛，特別是在生活領域(yu)被廣泛用于電(dian)動車，手電(dian)筒等常見電(dian)器。它一般是給電(dian)池直接充電(dian)，不通過任何中介設(she)備和裝置.

　　充電器的流程

　　充(chong)(chong)電(dian)(dian)(dian)(dian)器的流程是(shi)：恒(heng)流-恒(heng)壓-涓流，三(san)階式(shi)智能(neng)充(chong)(chong)電(dian)(dian)(dian)(dian)。充(chong)(chong)電(dian)(dian)(dian)(dian)過程中的三(san)段式(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)理論(lun)則可以大大提(ti)高(gao)電(dian)(dian)(dian)(dian)池的充(chong)(chong)電(dian)(dian)(dian)(dian)效率(lv)，縮短充(chong)(chong)電(dian)(dian)(dian)(dian)時間，并能(neng)有(you)效延長電(dian)(dian)(dian)(dian)池壽命。三(san)段式(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)采用先恒(heng)流充(chong)(chong)電(dian)(dian)(dian)(dian)，再(zai)恒(heng)壓充(chong)(chong)電(dian)(dian)(dian)(dian)，最后采用浮(fu)充(chong)(chong)進行維護充(chong)(chong)電(dian)(dian)(dian)(dian)。

　　一般分為快速充(chong)電(dian)(dian)、補足充(chong)電(dian)(dian)、涓流充(chong)電(dian)(dian)三個階段:

　　1、快(kuai)速(su)充(chong)電(dian)(dian)階(jie)段：用(yong)大電(dian)(dian)流對電(dian)(dian)池(chi)(chi)進行充(chong)電(dian)(dian)以(yi)迅(xun)速(su)恢復電(dian)(dian)池(chi)(chi)電(dian)(dian)能，充(chong)電(dian)(dian)速(su)率可以(yi)達1C以(yi)上，此時充(chong)電(dian)(dian)電(dian)(dian)壓較低，但會限(xian)制充(chong)電(dian)(dian)電(dian)(dian)流在一定數(shu)值(zhi)范圍之(zhi)內。

　　2、補(bu)足(zu)充電(dian)(dian)階(jie)段：相對于快速(su)充電(dian)(dian)階(jie)段，補(bu)足(zu)充電(dian)(dian)階(jie)段又(you)可以稱為慢(man)速(su)充電(dian)(dian)階(jie)段。當快速(su)充電(dian)(dian)階(jie)段終(zhong)止時，電(dian)(dian)池并(bing)(bing)未完全充足(zu)，還需加入補(bu)足(zu)充電(dian)(dian)過程，補(bu)足(zu)充電(dian)(dian)速(su)率一般不超過0.3C，因為電(dian)(dian)池電(dian)(dian)壓經過快速(su)充電(dian)(dian)階(jie)段后有所(suo)升高，所(suo)以補(bu)足(zu)充電(dian)(dian)階(jie)段的充電(dian)(dian)電(dian)(dian)壓也應該有所(suo)提升，并(bing)(bing)且恒(heng)定(ding)在一定(ding)范圍之(zhi)內。

　　3、涓流充(chong)(chong)(chong)電(dian)(dian)(dian)階段(duan)：在補足充(chong)(chong)(chong)電(dian)(dian)(dian)階段(duan)后期，當檢測到(dao)溫度上升超過極限值或充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流減小到(dao)一定值之后，開始用(yong)更(geng)小的電(dian)(dian)(dian)流進行充(chong)(chong)(chong)電(dian)(dian)(dian)直至滿足一定的條件后結(jie)束充(chong)(chong)(chong)電(dian)(dian)(dian)。

　　二、電源適配器

　　電源適(shi)配器:英文(wen)名稱Adapter，市場上常見的(de)(de)電源適(shi)配器是(shi)經過變壓(ya)(ya)，整流(liu)和穩壓(ya)(ya)的(de)(de)電源變換器，輸(shu)出(chu)的(de)(de)是(shi)直流(liu)，在滿足功(gong)率的(de)(de)情(qing)況下(xia)可以理解為低壓(ya)(ya)穩壓(ya)(ya)電源。

　　電(dian)(dian)源適配(pei)器廣泛配(pei)套于路(lu)由器、電(dian)(dian)話子母(mu)機、游戲機、語言復讀(du)機、隨身(shen)聽、筆記本、手(shou)機等設備中。大部(bu)分電(dian)(dian)源適配(pei)器可以自動檢(jian)測100～240V交(jiao)流電(dian)(dian)(50/60Hz)。

　　電(dian)源(yuan)(yuan)適配器是小(xiao)型便攜式電(dian)子設備(bei)及電(dian)子電(dian)器的供電(dian)電(dian)源(yuan)(yuan)變換設備(bei)，它把(ba)電(dian)源(yuan)(yuan)外置，用一條線和(he)主(zhu)機連接，這(zhe)樣(yang)可以縮小(xiao)主(zhu)機的體(ti)積和(he)重量，只有極少數的設備(bei)和(he)電(dian)器把(ba)電(dian)源(yuan)(yuan)內(nei)置在(zai)主(zhu)機內(nei)。

　　它內部由電(dian)源變壓(ya)(ya)器和整(zheng)流(liu)(liu)電(dian)路組成，按其輸(shu)(shu)出類(lei)型(xing)可(ke)(ke)分(fen)(fen)為(wei)交流(liu)(liu)輸(shu)(shu)出型(xing)和直流(liu)(liu)輸(shu)(shu)出型(xing);按連(lian)接方(fang)式(shi)可(ke)(ke)分(fen)(fen)為(wei)插墻式(shi)和桌面式(shi)。在電(dian)源適配(pei)器上都(dou)有(you)一個(ge)銘牌，上面標示著功率，輸(shu)(shu)入輸(shu)(shu)出電(dian)壓(ya)(ya)和電(dian)流(liu)(liu)量等指標，特別要注意輸(shu)(shu)入電(dian)壓(ya)(ya)的范圍(wei)。

　　看了以上介紹，相(xiang)信大(da)家對于電(dian)(dian)源適配(pei)器(qi)和(he)充電(dian)(dian)器(qi)有了簡(jian)單(dan)了解，其區別和(he)關系(xi)自然也有所了解。總之電(dian)(dian)源適配(pei)器(qi)和(he)充電(dian)(dian)器(qi)都(dou)是我(wo)們生活中必要的(de)設備一定(ding)要慎重(zhong)選擇!
