移動電源的特點：移動性(xing)、通用性(xing)、工藝性(xing)

移(yi)(yi)動電(dian)(dian)源的移(yi)(yi)動性是指(zhi)產(chan)品能在移(yi)(yi)動狀態(tai)下(xia)(xia)（例如旅游，開會(hui)，充電(dian)(dian)器不在身邊或不方便(bian)充電(dian)(dian)情況下(xia)(xia)）發揮其功用，即在anywhere（任何地點），anytime（任何時間）不受局限(xian)地給數碼產(chan)品供電(dian)(dian)或充電(dian)(dian)，真實(shi)地給人以(yi)踏實(shi)感(gan)，使生活和工作的品質得以(yi)提升。

移(yi)動(dong)(dong)電(dian)(dian)(dian)(dian)源(yuan)的(de)(de)(de)(de)(de)通用性是指產(chan)(chan)品(pin)(pin)能(neng)(neng)夠(gou)適合最大范(fan)圍的(de)(de)(de)(de)(de)數(shu)碼(ma)產(chan)(chan)品(pin)(pin)。即移(yi)動(dong)(dong)電(dian)(dian)(dian)(dian)源(yuan)能(neng)(neng)夠(gou)為手機(ji)(ji)、MP3、MP4、PDA、游(you)戲機(ji)(ji)（PSP等）、藍牙耳機(ji)(ji)、數(shu)碼(ma)相(xiang)機(ji)(ji)、CD播放機(ji)(ji)、復(fu)讀(du)機(ji)(ji)、數(shu)碼(ma)攝像機(ji)(ji)、便(bian)(bian)攜式DVD、手提電(dian)(dian)(dian)(dian)腦等多(duo)種(zhong)數(shu)碼(ma)產(chan)(chan)品(pin)(pin)服務。不(bu)過(guo)對于使(shi)用電(dian)(dian)(dian)(dian)壓(ya)較高的(de)(de)(de)(de)(de)相(xiang)關(guan)數(shu)碼(ma)產(chan)(chan)品(pin)(pin)，比如手提之(zhi)類的(de)(de)(de)(de)(de)，則需(xu)要配置(zhi)輸出電(dian)(dian)(dian)(dian)壓(ya)較高的(de)(de)(de)(de)(de)移(yi)動(dong)(dong)電(dian)(dian)(dian)(dian)源(yuan)，這個(ge)與移(yi)動(dong)(dong)電(dian)(dian)(dian)(dian)源(yuan)本身實際的(de)(de)(de)(de)(de)容量成正比。其實，不(bu)僅(jin)如此(ci)，移(yi)動(dong)(dong)電(dian)(dian)(dian)(dian)源(yuan)可(ke)以通過(guo)usb電(dian)(dian)(dian)(dian)纜(lan)線(xian)使(shi)用在任何(he)符合USB On-the-Go (USB-OTG)的(de)(de)(de)(de)(de)便(bian)(bian)攜型設備（usb電(dian)(dian)(dian)(dian)燈，usb眼(yan)睛按摩器，usb電(dian)(dian)(dian)(dian)熱咖啡(fei)壺等等等）上，作為移(yi)動(dong)(dong)的(de)(de)(de)(de)(de)最方便(bian)(bian)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)供應。對移(yi)動(dong)(dong)電(dian)(dian)(dian)(dian)源(yuan)來說，它(ta)具(ju)有(you)一(yi)定(ding)的(de)(de)(de)(de)(de)應急(ji)功能(neng)(neng)，在眾多(duo)的(de)(de)(de)(de)(de)數(shu)碼(ma)產(chan)(chan)品(pin)(pin)電(dian)(dian)(dian)(dian)源(yuan)不(bu)能(neng)(neng)蓄(xu)電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)情況下，可(ke)以通過(guo)某些裝置(zhi)供電(dian)(dian)(dian)(dian)，以達數(shu)碼(ma)產(chan)(chan)品(pin)(pin)正常工作的(de)(de)(de)(de)(de)效果。如市(shi)場出現的(de)(de)(de)(de)(de)太陽能(neng)(neng)移(yi)動(dong)(dong)電(dian)(dian)(dian)(dian)源(yuan)、手搖發電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)(de)(de)移(yi)動(dong)(dong)電(dian)(dian)(dian)(dian)源(yuan)、智(zhi)能(neng)(neng)機(ji)(ji)備用電(dian)(dian)(dian)(dian)源(yuan)。

移動電源的(de)(de)工藝性是指產(chan)品的(de)(de)外(wai)觀(guan)設計(ji)參入了消費(fei)者(zhe)的(de)(de)大(da)眾或者(zhe)小眾的(de)(de)審(shen)美觀(guan)。作為隨身攜(xie)帶(dai)且具(ju)有一定功用的(de)(de)電子產(chan)品，消費(fei)者(zhe)很注(zhu)重(zhong)其外(wai)觀(guan)的(de)(de)美觀(guan)性，所(suo)以現在主流廠(chang)商不(bu)僅在加(jia)大(da)電池電源管理技術革新的(de)(de)同(tong)時，也(ye)在加(jia)大(da)符合消費(fei)者(zhe)審(shen)美觀(guan)的(de)(de)產(chan)品外(wai)觀(guan)的(de)(de)研發。

移動電源的工作原理：

移動(dong)電(dian)(dian)(dian)(dian)源(yuan)是(shi)一(yi)個集(ji)儲電(dian)(dian)(dian)(dian)，升(sheng)壓(ya)，充電(dian)(dian)(dian)(dian)管(guan)理于(yu)一(yi)體的便攜式設備。儲電(dian)(dian)(dian)(dian)介質一(yi)般采用鋰(li)(li)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)芯，因為鋰(li)(li)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)芯體積(ji)相對小(xiao)巧(qiao)，容量(liang)大，市場(chang)流通(tong)廣，價(jia)格適(shi)中，被廣泛用于(yu)數碼產品(pin)。鋰(li)(li)電(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)壓(ya)在2.7-4.2V 之(zhi)間，電(dian)(dian)(dian)(dian)壓(ya)隨著電(dian)(dian)(dian)(dian)量(liang)的下(xia)(xia)降而(er)下(xia)(xia)降。而(er)2.7-4.2V的電(dian)(dian)(dian)(dian)壓(ya)是(shi)不能直接給(gei)其它數碼產品(pin)充電(dian)(dian)(dian)(dian)的，因為數碼產品(pin)的鋰(li)(li)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)也是(shi)2.7-4.2V,同電(dian)(dian)(dian)(dian)位(wei)的電(dian)(dian)(dian)(dian)壓(ya)之(zhi)間是(shi)不能充電(dian)(dian)(dian)(dian)的。所(suo)以移動(dong)電(dian)(dian)(dian)(dian)源(yuan)向外(wai)輸出電(dian)(dian)(dian)(dian)能是(shi)必須(xu)要(yao)有升(sheng)壓(ya)系統(tong)，把(ba)2.7-4.2V 的鋰(li)(li)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)升(sheng)壓(ya)到(dao)5V，這樣就可(ke)以給(gei)其它數碼產品(pin)充電(dian)(dian)(dian)(dian)了，如手(shou)機、MP4、平(ping)板電(dian)(dian)(dian)(dian)腦、PSP等。

當(dang)然，移(yi)動(dong)電(dian)(dian)(dian)(dian)源(yuan)不是一(yi)次性設備，它可(ke)以(yi)反復使用(yong)數百次以(yi)上(shang)。所(suo)以(yi)當(dang)移(yi)動(dong)電(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)能使用(yong)完(wan)后，我(wo)們必須給移(yi)動(dong)電(dian)(dian)(dian)(dian)源(yuan)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)。其原理(li)(li)和給手機充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)一(yi)樣。連接到5V的(de)USB 電(dian)(dian)(dian)(dian)腦(nao)接口(kou)或(huo)USB 充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)上(shang)即可(ke)給移(yi)動(dong)電(dian)(dian)(dian)(dian)源(yuan)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)。所(suo)以(yi)移(yi)動(dong)電(dian)(dian)(dian)(dian)源(yuan)內部還(huan)必須有(you)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)管(guan)(guan)理(li)(li)系統。充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)管(guan)(guan)理(li)(li)系統能根據(ju)鋰電(dian)(dian)(dian)(dian)的(de)電(dian)(dian)(dian)(dian)壓，自動(dong)調節充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流。過程(cheng)有(you)：預充(chong)(chong)(chong)(chong)(chong)，恒壓充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，和浮充(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)等(deng)。

移動電源的組成部分：

　　電源電芯：常用的有聚合物鋰電、18650鋰電、AAA鎳氫電池。 　　聚合物電池：標準電壓3.7 V，形狀較多，可定制，具有容量大，物美價廉，應用廣泛，如：手機、MP4、便攜音箱等。 　　18650鋰電：標準電壓3.7V，體積小，容量大，標準電壓3.7V，主要用在筆記本電腦等高端產品。 　　AAA 鎳氫電池：標準電壓1.2V 。容量相對較小。應該廣泛，家用電器，玩家的等。 　　升壓系統： 　　升壓主流技術基本采用DC to DC 的升壓方式。國內技術轉換效率普遍低，一般在50-70%。臺灣的在75-80%。美國的相對會高些。也有降壓方案的，效率比較高，但對電芯的一致性要求高，所以幾乎很少采用。 　　根據產品轉換效率計算電源輸出電量： 　　以力客LK-5200移動電源為例： 　　實際輸出容量=(移動電源容量5200mAhx3.7Vx轉化率85%)/5V=3270mAh 　　充電管理系統： 　　目前國內充電管理系統比較成熟，智能IC監控整個充電過程。主流管理IC 有PT4056,PX40等。充電時間5000maH 大約8小時。過快充對電池的壽命有不良影響。
