電源適配器和(he)充(chong)電器(qi)(qi)在我們(men)的生活中都十分常見，都是充(chong)電的輔助設(she)備(bei)。但是電源適配器(qi)(qi)和(he)充(chong)電器(qi)(qi)是什么(me)?有什么(me)區別和(he)關系(xi)?這些你都了解嗎?今(jin)天我們(men)一(yi)(yi)起來看一(yi)(yi)下。

　　一、充電器

　　充電(dian)器(qi)(qi):英文名稱Charger，通常(chang)指的是一(yi)種將交流電(dian)轉換為低壓直(zhi)流電(dian)的設(she)備，充電(dian)器(qi)(qi)是給(gei)可充電(dian)電(dian)池(chi)用(yong)的專用(yong)直(zhi)流電(dian)源，它內部包(bao)括了限流，限壓等(deng)滿足(zu)充電(dian)特性的控(kong)制電(dian)路(lu)。

　　充電(dian)器在各個領域用(yong)途廣泛，特(te)別是在生活領域被(bei)廣泛用(yong)于(yu)電(dian)動車，手電(dian)筒等常見電(dian)器。它一(yi)般是給(gei)電(dian)池直接(jie)充電(dian)，不通過(guo)任何中介(jie)設備和裝置.

　　充電器的流程

　　充電(dian)器的(de)流程(cheng)是：恒(heng)(heng)流-恒(heng)(heng)壓(ya)(ya)-涓(juan)流，三(san)階式智能充電(dian)。充電(dian)過程(cheng)中的(de)三(san)段(duan)式充電(dian)理論則可以大大提高電(dian)池(chi)的(de)充電(dian)效(xiao)率(lv)，縮短充電(dian)時(shi)間，并能有效(xiao)延(yan)長電(dian)池(chi)壽命。三(san)段(duan)式充電(dian)采(cai)用先恒(heng)(heng)流充電(dian)，再恒(heng)(heng)壓(ya)(ya)充電(dian)，最后(hou)采(cai)用浮充進(jin)行維護充電(dian)。

　　一般分為快速充電(dian)、補足(zu)充電(dian)、涓流充電(dian)三個階(jie)段:

　　1、快速充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段：用大(da)電(dian)(dian)(dian)流對電(dian)(dian)(dian)池(chi)進行充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)以迅速恢復電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)能(neng)，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)速率(lv)可以達1C以上，此時充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓較低，但會限制充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流在一定(ding)數值(zhi)范圍之內。

　　2、補(bu)(bu)足(zu)(zu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段(duan)(duan)：相對于快速充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段(duan)(duan)，補(bu)(bu)足(zu)(zu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段(duan)(duan)又(you)可以稱(cheng)為(wei)慢速充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段(duan)(duan)。當快速充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段(duan)(duan)終止時，電(dian)(dian)(dian)池(chi)并未完全(quan)充(chong)(chong)(chong)(chong)(chong)足(zu)(zu)，還(huan)需加入補(bu)(bu)足(zu)(zu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)過程，補(bu)(bu)足(zu)(zu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)速率(lv)一般(ban)不超過0.3C，因為(wei)電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓經過快速充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段(duan)(duan)后有所(suo)升高，所(suo)以補(bu)(bu)足(zu)(zu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段(duan)(duan)的(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓也應該有所(suo)提升，并且恒定在一定范圍之內。

　　3、涓流(liu)充(chong)電(dian)(dian)階段：在補足(zu)充(chong)電(dian)(dian)階段后期，當檢測(ce)到溫度上升超過(guo)極限值或充(chong)電(dian)(dian)電(dian)(dian)流(liu)減小到一定(ding)(ding)值之(zhi)后，開始用更(geng)小的(de)電(dian)(dian)流(liu)進行(xing)充(chong)電(dian)(dian)直至滿(man)足(zu)一定(ding)(ding)的(de)條件后結束充(chong)電(dian)(dian)。

　　二、電源適配器

　　電源(yuan)(yuan)適配器(qi):英文(wen)名稱Adapter，市場上常見的電源(yuan)(yuan)適配器(qi)是經過變(bian)(bian)壓(ya)，整(zheng)流和(he)穩(wen)壓(ya)的電源(yuan)(yuan)變(bian)(bian)換器(qi)，輸出的是直流，在(zai)滿足功率的情況下可(ke)以理解為低壓(ya)穩(wen)壓(ya)電源(yuan)(yuan)。

　　電(dian)(dian)源適(shi)配器廣泛配套于(yu)路由器、電(dian)(dian)話子母機(ji)、游戲機(ji)、語言復讀機(ji)、隨身聽(ting)、筆記本、手機(ji)等設備中。大部分(fen)電(dian)(dian)源適(shi)配器可以自動檢測100～240V交流(liu)電(dian)(dian)(50/60Hz)。

　　電源(yuan)適配器是小(xiao)型便攜式電子設(she)備(bei)及電子電器的供(gong)電電源(yuan)變(bian)換設(she)備(bei)，它把電源(yuan)外置，用一條(tiao)線和(he)主機(ji)(ji)連接，這樣(yang)可以縮小(xiao)主機(ji)(ji)的體積和(he)重量，只有極少數(shu)的設(she)備(bei)和(he)電器把電源(yuan)內(nei)(nei)置在主機(ji)(ji)內(nei)(nei)。

　　它(ta)內部由電(dian)(dian)源變壓(ya)器和(he)整流電(dian)(dian)路組成，按其輸出類型(xing)可(ke)分為(wei)(wei)交流輸出型(xing)和(he)直(zhi)流輸出型(xing);按連接方式(shi)可(ke)分為(wei)(wei)插墻式(shi)和(he)桌面式(shi)。在電(dian)(dian)源適配器上(shang)都有(you)一(yi)個銘牌(pai)，上(shang)面標(biao)示著功率，輸入輸出電(dian)(dian)壓(ya)和(he)電(dian)(dian)流量等指標(biao)，特別要注意(yi)輸入電(dian)(dian)壓(ya)的范圍。

　　看了以(yi)上(shang)介紹(shao)，相信(xin)大家對于電(dian)源(yuan)(yuan)適配(pei)器和(he)充電(dian)器有(you)了簡單了解，其區別和(he)關(guan)系自然也有(you)所了解。總之電(dian)源(yuan)(yuan)適配(pei)器和(he)充電(dian)器都是(shi)我(wo)們生活中必要(yao)的設備(bei)一定要(yao)慎(shen)重選(xuan)擇!
