電源適配器和充(chong)(chong)電器(qi)在我(wo)(wo)們(men)的生活中都(dou)十分常見，都(dou)是(shi)充(chong)(chong)電的輔(fu)助(zhu)設備。但是(shi)電源適配器(qi)和充(chong)(chong)電器(qi)是(shi)什么?有什么區別和關系?這些你都(dou)了(le)解(jie)嗎?今天我(wo)(wo)們(men)一起來看一下。

　　一、充電器

　　充(chong)電器:英(ying)文名(ming)稱(cheng)Charger，通(tong)常指的(de)是一(yi)種將交(jiao)流(liu)(liu)電轉換(huan)為(wei)低(di)壓直(zhi)流(liu)(liu)電的(de)設備，充(chong)電器是給可充(chong)電電池用的(de)專用直(zhi)流(liu)(liu)電源，它內部包括了限流(liu)(liu)，限壓等滿足(zu)充(chong)電特性的(de)控制電路。

　　充電(dian)(dian)器(qi)在(zai)各個領域(yu)用途廣(guang)泛，特別(bie)是在(zai)生活(huo)領域(yu)被廣(guang)泛用于電(dian)(dian)動車，手電(dian)(dian)筒等(deng)常見電(dian)(dian)器(qi)。它一般是給電(dian)(dian)池直接充電(dian)(dian)，不通過任何(he)中介設(she)備(bei)和裝置.

　　充電器的流程

　　充(chong)(chong)電(dian)器的流程是：恒(heng)流-恒(heng)壓-涓(juan)流，三(san)階式智能充(chong)(chong)電(dian)。充(chong)(chong)電(dian)過程中(zhong)的三(san)段(duan)式充(chong)(chong)電(dian)理論則可以大(da)大(da)提(ti)高(gao)電(dian)池的充(chong)(chong)電(dian)效率，縮短充(chong)(chong)電(dian)時間(jian)，并能有效延長電(dian)池壽命。三(san)段(duan)式充(chong)(chong)電(dian)采用(yong)先恒(heng)流充(chong)(chong)電(dian)，再恒(heng)壓充(chong)(chong)電(dian)，最后采用(yong)浮充(chong)(chong)進行(xing)維(wei)護充(chong)(chong)電(dian)。

　　一(yi)般(ban)分為(wei)快速充(chong)電(dian)、補(bu)足充(chong)電(dian)、涓(juan)流充(chong)電(dian)三(san)個階(jie)段:

　　1、快速(su)充電(dian)階段：用大電(dian)流對電(dian)池進行充電(dian)以(yi)迅速(su)恢復電(dian)池電(dian)能，充電(dian)速(su)率可(ke)以(yi)達(da)1C以(yi)上，此(ci)時充電(dian)電(dian)壓較(jiao)低，但會限制(zhi)充電(dian)電(dian)流在一定數(shu)值范圍之內。

　　2、補足(zu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)階(jie)段(duan)(duan)：相對于快(kuai)速(su)(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)階(jie)段(duan)(duan)，補足(zu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)階(jie)段(duan)(duan)又可以(yi)稱為慢速(su)(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)階(jie)段(duan)(duan)。當快(kuai)速(su)(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)階(jie)段(duan)(duan)終止(zhi)時，電(dian)(dian)(dian)(dian)(dian)池(chi)并(bing)未(wei)完全充(chong)(chong)足(zu)，還需加入補足(zu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)過程，補足(zu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)速(su)(su)率(lv)一般不超過0.3C，因為電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)壓經過快(kuai)速(su)(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)階(jie)段(duan)(duan)后(hou)有所(suo)升高，所(suo)以(yi)補足(zu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)階(jie)段(duan)(duan)的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓也(ye)應(ying)該(gai)有所(suo)提升，并(bing)且恒定在(zai)一定范圍之內。

　　3、涓流(liu)充電(dian)(dian)(dian)(dian)階(jie)(jie)段：在補足充電(dian)(dian)(dian)(dian)階(jie)(jie)段后(hou)(hou)期，當檢測(ce)到溫度上升超(chao)過極限值或(huo)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)減小(xiao)到一定值之后(hou)(hou)，開始(shi)用更(geng)小(xiao)的電(dian)(dian)(dian)(dian)流(liu)進行充電(dian)(dian)(dian)(dian)直至(zhi)滿足一定的條(tiao)件后(hou)(hou)結(jie)束充電(dian)(dian)(dian)(dian)。

　　二、電源適配器

　　電(dian)(dian)源適配(pei)器:英文名稱Adapter，市場(chang)上(shang)常見(jian)的電(dian)(dian)源適配(pei)器是(shi)經過變(bian)壓(ya)(ya)(ya)，整流和穩(wen)(wen)壓(ya)(ya)(ya)的電(dian)(dian)源變(bian)換器，輸出的是(shi)直流，在滿(man)足功率的情況下可(ke)以(yi)理解為低壓(ya)(ya)(ya)穩(wen)(wen)壓(ya)(ya)(ya)電(dian)(dian)源。

　　電(dian)(dian)源適配器(qi)廣泛配套于路由器(qi)、電(dian)(dian)話(hua)子母機(ji)、游戲機(ji)、語言復讀機(ji)、隨身(shen)聽、筆記本、手(shou)機(ji)等(deng)設備中(zhong)。大(da)部分電(dian)(dian)源適配器(qi)可以(yi)自動(dong)檢測100～240V交流(liu)電(dian)(dian)(50/60Hz)。

　　電源適配器(qi)是(shi)小(xiao)型便(bian)攜式電子設備(bei)及(ji)電子電器(qi)的供電電源變換設備(bei)，它把(ba)電源外置，用一(yi)條線和主(zhu)(zhu)機(ji)連接，這樣可以縮小(xiao)主(zhu)(zhu)機(ji)的體(ti)積和重量，只(zhi)有極少數的設備(bei)和電器(qi)把(ba)電源內(nei)置在主(zhu)(zhu)機(ji)內(nei)。

　　它內部(bu)由電(dian)源變壓(ya)器(qi)和整流(liu)電(dian)路(lu)組(zu)成，按其輸(shu)(shu)出類型可分為交流(liu)輸(shu)(shu)出型和直流(liu)輸(shu)(shu)出型;按連接方(fang)式(shi)可分為插墻式(shi)和桌面式(shi)。在電(dian)源適配器(qi)上都有一個銘牌，上面標示著功率，輸(shu)(shu)入(ru)輸(shu)(shu)出電(dian)壓(ya)和電(dian)流(liu)量等指(zhi)標，特別(bie)要注意(yi)輸(shu)(shu)入(ru)電(dian)壓(ya)的范圍。

　　看了以上介紹，相(xiang)信大家對(dui)于電源適配器和(he)(he)(he)充電器有了簡單了解(jie)，其區別和(he)(he)(he)關系自然也有所了解(jie)。總(zong)之電源適配器和(he)(he)(he)充電器都是我們生活中必要的設備一定要慎重(zhong)選擇(ze)!
