電源適配器和(he)充(chong)電(dian)(dian)(dian)器(qi)在我們的生活中(zhong)都十分常見，都是(shi)充(chong)電(dian)(dian)(dian)的輔助設備。但(dan)是(shi)電(dian)(dian)(dian)源適配器(qi)和(he)充(chong)電(dian)(dian)(dian)器(qi)是(shi)什么(me)?有什么(me)區別和(he)關系?這些你都了解嗎(ma)?今天我們一起來看一下(xia)。

　　一、充電器

　　充電(dian)(dian)(dian)(dian)器:英文名稱Charger，通常指的(de)是(shi)一種將(jiang)交流電(dian)(dian)(dian)(dian)轉換(huan)為低壓直流電(dian)(dian)(dian)(dian)的(de)設備，充電(dian)(dian)(dian)(dian)器是(shi)給可(ke)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池用的(de)專(zhuan)用直流電(dian)(dian)(dian)(dian)源，它內部(bu)包括了限(xian)流，限(xian)壓等(deng)滿足充電(dian)(dian)(dian)(dian)特性的(de)控制電(dian)(dian)(dian)(dian)路(lu)。

　　充(chong)電(dian)器在(zai)各個領域用途廣(guang)泛，特別是在(zai)生活領域被廣(guang)泛用于電(dian)動車，手電(dian)筒等常見(jian)電(dian)器。它一般是給電(dian)池直接充(chong)電(dian)，不通過任何中介(jie)設備和(he)裝置.

　　充電器的流程

　　充(chong)(chong)電(dian)(dian)器的(de)流程(cheng)是(shi)：恒(heng)流-恒(heng)壓-涓流，三階式(shi)智能(neng)充(chong)(chong)電(dian)(dian)。充(chong)(chong)電(dian)(dian)過(guo)程(cheng)中的(de)三段式(shi)充(chong)(chong)電(dian)(dian)理論則可(ke)以(yi)大(da)大(da)提高電(dian)(dian)池(chi)的(de)充(chong)(chong)電(dian)(dian)效率，縮短充(chong)(chong)電(dian)(dian)時間(jian)，并能(neng)有效延長(chang)電(dian)(dian)池(chi)壽命。三段式(shi)充(chong)(chong)電(dian)(dian)采(cai)用先恒(heng)流充(chong)(chong)電(dian)(dian)，再恒(heng)壓充(chong)(chong)電(dian)(dian)，最后采(cai)用浮充(chong)(chong)進行(xing)維護充(chong)(chong)電(dian)(dian)。

　　一(yi)般分為快(kuai)速充(chong)電(dian)、補足充(chong)電(dian)、涓流充(chong)電(dian)三個階段:

　　1、快速充電(dian)(dian)階(jie)段(duan)：用(yong)大電(dian)(dian)流(liu)對電(dian)(dian)池進行充電(dian)(dian)以迅速恢復電(dian)(dian)池電(dian)(dian)能，充電(dian)(dian)速率可以達1C以上，此時充電(dian)(dian)電(dian)(dian)壓(ya)較低，但會限制充電(dian)(dian)電(dian)(dian)流(liu)在一定數(shu)值范圍之內。

　　2、補(bu)(bu)(bu)足(zu)充(chong)(chong)(chong)電階(jie)(jie)(jie)段(duan)：相(xiang)對于快(kuai)(kuai)速(su)(su)充(chong)(chong)(chong)電階(jie)(jie)(jie)段(duan)，補(bu)(bu)(bu)足(zu)充(chong)(chong)(chong)電階(jie)(jie)(jie)段(duan)又可(ke)以(yi)稱為(wei)慢速(su)(su)充(chong)(chong)(chong)電階(jie)(jie)(jie)段(duan)。當(dang)快(kuai)(kuai)速(su)(su)充(chong)(chong)(chong)電階(jie)(jie)(jie)段(duan)終(zhong)止時(shi)，電池并未完全充(chong)(chong)(chong)足(zu)，還需加入補(bu)(bu)(bu)足(zu)充(chong)(chong)(chong)電過程，補(bu)(bu)(bu)足(zu)充(chong)(chong)(chong)電速(su)(su)率一般不超過0.3C，因為(wei)電池電壓(ya)(ya)經過快(kuai)(kuai)速(su)(su)充(chong)(chong)(chong)電階(jie)(jie)(jie)段(duan)后有所(suo)(suo)升高，所(suo)(suo)以(yi)補(bu)(bu)(bu)足(zu)充(chong)(chong)(chong)電階(jie)(jie)(jie)段(duan)的(de)充(chong)(chong)(chong)電電壓(ya)(ya)也應該(gai)有所(suo)(suo)提升，并且恒定(ding)在一定(ding)范圍(wei)之(zhi)內。

　　3、涓流充電(dian)階(jie)段：在補足充電(dian)階(jie)段后期，當檢(jian)測到溫度上升超過極限值或充電(dian)電(dian)流減(jian)小到一(yi)定(ding)值之后，開始用更小的電(dian)流進行(xing)充電(dian)直至滿足一(yi)定(ding)的條件后結束充電(dian)。

　　二、電源適配器

　　電(dian)源適配(pei)器(qi):英文名(ming)稱Adapter，市場上常(chang)見的電(dian)源適配(pei)器(qi)是經(jing)過變壓，整流和穩壓的電(dian)源變換器(qi)，輸(shu)出的是直流，在滿足功率的情況下可以理(li)解為低壓穩壓電(dian)源。

　　電(dian)(dian)源適配(pei)器(qi)廣泛(fan)配(pei)套(tao)于(yu)路由器(qi)、電(dian)(dian)話子母機(ji)(ji)、游戲機(ji)(ji)、語(yu)言復讀機(ji)(ji)、隨身聽、筆記本、手機(ji)(ji)等設備中。大部分電(dian)(dian)源適配(pei)器(qi)可以(yi)自(zi)動檢測100～240V交流(liu)電(dian)(dian)(50/60Hz)。

　　電(dian)源(yuan)適配器是小型便攜式電(dian)子設(she)備及電(dian)子電(dian)器的供電(dian)電(dian)源(yuan)變換設(she)備，它把電(dian)源(yuan)外置，用(yong)一條線(xian)和主(zhu)(zhu)機連(lian)接(jie)，這樣可以縮小主(zhu)(zhu)機的體積和重量，只有極少數的設(she)備和電(dian)器把電(dian)源(yuan)內(nei)置在主(zhu)(zhu)機內(nei)。

　　它內部(bu)由(you)電源(yuan)變壓(ya)(ya)器和整流電路組成，按其輸出類型可分為交流輸出型和直流輸出型;按連接(jie)方(fang)式可分為插墻式和桌面(mian)式。在電源(yuan)適配器上都有(you)一個銘牌(pai)，上面(mian)標示(shi)著功率，輸入(ru)輸出電壓(ya)(ya)和電流量等(deng)指標，特別要(yao)注意輸入(ru)電壓(ya)(ya)的范圍。

　　看了(le)(le)(le)以上介紹，相信大(da)家對于電(dian)(dian)源適配器(qi)和(he)充電(dian)(dian)器(qi)有了(le)(le)(le)簡單了(le)(le)(le)解(jie)，其區別和(he)關系自然也有所了(le)(le)(le)解(jie)。總之電(dian)(dian)源適配器(qi)和(he)充電(dian)(dian)器(qi)都是我們生活中必要的設備一定要慎重選擇(ze)!
