現在太陽能充電器已經(jing)很常(chang)見(jian)了(le)，那么就會有更多(duo)人(ren)來關注太陽能充電(dian)器(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)性(xing)能問(wen)題。要(yao)(yao)評價一款太陽能充電(dian)器(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)性(xing)能，可(ke)以從下面(mian)(mian)三個方面(mian)(mian)來看：電(dian)池： 由于(yu)太陽能充電(dian)器(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)使(shi)用(yong)環境跟普通的(de)(de)(de)(de)(de)(de)電(dian)子產品(pin)(pin)有所不同，所以太陽能充電(dian)器(qi)(qi)(qi)對內置(zhi)電(dian)池的(de)(de)(de)(de)(de)(de)要(yao)(yao)求也最高。但這(zhe)恰(qia)恰(qia)是(shi)消(xiao)費者(zhe)容(rong)易忽略的(de)(de)(de)(de)(de)(de)地(di)方，同時也是(shi)一些缺(que)乏社(she)會責任感(gan)的(de)(de)(de)(de)(de)(de)廠家容(rong)易做(zuo)手腳(jiao)的(de)(de)(de)(de)(de)(de)地(di)方。在市(shi)面(mian)(mian)上(shang)，一塊同樣容(rong)量的(de)(de)(de)(de)(de)(de)電(dian)池價格可(ke)能相(xiang)差(cha)好幾(ji)倍，所以，某(mou)些山寨廠商(shang)就瞄準了(le)這(zhe)塊的(de)(de)(de)(de)(de)(de)暴利，很多(duo)非常(chang)廉價的(de)(de)(de)(de)(de)(de)充電(dian)器(qi)(qi)(qi)使(shi)用(yong)的(de)(de)(de)(de)(de)(de)都是(shi)二(er)次(ci)電(dian)芯翻新后的(de)(de)(de)(de)(de)(de)電(dian)池，好點的(de)(de)(de)(de)(de)(de)就是(shi)用(yong)電(dian)池里的(de)(de)(de)(de)(de)(de)B品(pin)(pin)、C品(pin)(pin)的(de)(de)(de)(de)(de)(de)電(dian)池。這(zhe)樣的(de)(de)(de)(de)(de)(de)電(dian)池使(shi)用(yong)壽命短不說，還有可(ke)能給消(xiao)費者(zhe)帶來人(ren)身安(an)全上(shang)的(de)(de)(de)(de)(de)(de)風險。

    太陽能充電器的(de)(de)內置電(dian)(dian)(dian)池(chi)應以鋰(li)聚(ju)合物(wu)電(dian)(dian)(dian)池(chi)為佳，相對于平時(shi)(shi)我們(men)常見(jian)的(de)(de)鋰(li)電(dian)(dian)(dian)池(chi)（液態(tai)鋰(li)離子），聚(ju)合物(wu)電(dian)(dian)(dian)池(chi)的(de)(de)鋰(li)離子成膠(jiao)體(ti)裝，活躍(yue)程度遠(yuan)小于液態(tai)鋰(li)離子電(dian)(dian)(dian)池(chi)，因此(ci)不會產生(sheng)爆炸。并且為適用太陽(yang)能充電(dian)(dian)(dian)器的(de)(de)使(shi)用環境，聚(ju)合物(wu)電(dian)(dian)(dian)池(chi)最好經(jing)過高溫處(chu)(chu)理，提升(sheng)電(dian)(dian)(dian)池(chi)的(de)(de)耐(nai)高溫極限(xian)。 最后，需要注意的(de)(de)是外殼(ke)表(biao)(biao)面(mian)處(chu)(chu)理和它的(de)(de)各種附件。市面(mian)上常見(jian)的(de)(de)太陽(yang)能充電(dian)(dian)(dian)器以塑(su)膠(jiao)殼(ke)為主，外表(biao)(biao)處(chu)(chu)理主要有(you)亮油、橡膠(jiao)漆，UV。亮油價格比(bi)較便宜(yi)，同時(shi)(shi)表(biao)(biao)面(mian)容易出現劃痕(hen)。橡膠(jiao)漆手感非(fei)常舒適，但隨使(shi)用時(shi)(shi)間(jian)的(de)(de)增加會掉漆。UV一般只在(zai)高檔品牌手機上才(cai)使(shi)用，價格昂貴。

     采用UV處理，產(chan)(chan)品表面(mian)(mian)(mian)(mian)光(guang)潔精細，同(tong)時(shi)硬度(du)好，不(bu)(bu)掉漆(qi)，不(bu)(bu)會留劃痕。 如果太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)充電(dian)器(qi)有(you)(you)配(pei)DC適配(pei)器(qi)，多(duo)關注一(yi)下DC適配(pei)器(qi)的(de)(de)(de)(de)(de)(de)(de)質量(liang)是(shi)有(you)(you)必要(yao)的(de)(de)(de)(de)(de)(de)(de)。畢竟這(zhe)(zhe)關系(xi)到產(chan)(chan)品和(he)人身安全。太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)電(dian)池(chi)板(ban)(ban)(ban)(ban)： 目(mu)前市面(mian)(mian)(mian)(mian)上的(de)(de)(de)(de)(de)(de)(de)太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)電(dian)池(chi)分為(wei)非晶(jing)(jing)(jing)硅(gui)和(he)晶(jing)(jing)(jing)體(ti)(ti)硅(gui)。其中晶(jing)(jing)(jing)體(ti)(ti)硅(gui)又可分為(wei)多(duo)晶(jing)(jing)(jing)硅(gui)和(he)單晶(jing)(jing)(jing)硅(gui)。從三種材料的(de)(de)(de)(de)(de)(de)(de)光(guang)電(dian)轉換效率(lv)(lv)(lv)來(lai)(lai)看是(shi)：單晶(jing)(jing)(jing)硅(gui)（最(zui)高(gao)可達(da)１７％）>多(duo)晶(jing)(jing)(jing)硅(gui)（１２～１５％）>非晶(jing)(jing)(jing)硅(gui)（５％　左右）。但晶(jing)(jing)(jing)體(ti)(ti)硅(gui)（單晶(jing)(jing)(jing)硅(gui)和(he)多(duo)晶(jing)(jing)(jing)硅(gui)）的(de)(de)(de)(de)(de)(de)(de)在弱(ruo)光(guang)下基本上不(bu)(bu)會有(you)(you)電(dian)流產(chan)(chan)生，非晶(jing)(jing)(jing)硅(gui)弱(ruo)光(guang)型好（在弱(ruo)光(guang)下能(neng)(neng)量(liang)本來(lai)(lai)就(jiu)很少）。所以綜(zong)合(he)看來(lai)(lai)，宜(yi)用單晶(jing)(jing)(jing)硅(gui)或多(duo)晶(jing)(jing)(jing)硅(gui)作太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)電(dian)池(chi)的(de)(de)(de)(de)(de)(de)(de)材料。 接(jie)下來(lai)(lai)我(wo)們要(yao)關注的(de)(de)(de)(de)(de)(de)(de)重點就(jiu)是(shi)太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)電(dian)池(chi)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)(de)(de)功(gong)(gong)率(lv)(lv)(lv)，一(yi)般(ban)說來(lai)(lai)，太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)電(dian)池(chi)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)(de)(de)功(gong)(gong)率(lv)(lv)(lv)跟太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)晶(jing)(jing)(jing)片(pian)(pian)的(de)(de)(de)(de)(de)(de)(de)面(mian)(mian)(mian)(mian)積(ji)(ji)成(cheng)正比(bi)（太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)電(dian)池(chi)晶(jing)(jing)(jing)片(pian)(pian)的(de)(de)(de)(de)(de)(de)(de)面(mian)(mian)(mian)(mian)積(ji)(ji)不(bu)(bu)完(wan)全等(deng)同(tong)于太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)封(feng)裝面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)(de)(de)面(mian)(mian)(mian)(mian)積(ji)(ji)，因為(wei)有(you)(you)的(de)(de)(de)(de)(de)(de)(de)太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)雖然大(da)，但太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)晶(jing)(jing)(jing)片(pian)(pian)排列的(de)(de)(de)(de)(de)(de)(de)縫隙很寬，這(zhe)(zhe)樣的(de)(de)(de)(de)(de)(de)(de)太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)功(gong)(gong)率(lv)(lv)(lv)不(bu)(bu)一(yi)定高(gao)。比(bi)如我(wo)們的(de)(de)(de)(de)(de)(de)(de)VSC－０３雖然太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)面(mian)(mian)(mian)(mian)板(ban)(ban)(ban)(ban)不(bu)(bu)大(da)，但晶(jing)(jing)(jing)片(pian)(pian)排列緊密，在比(bi)較小的(de)(de)(de)(de)(de)(de)(de)面(mian)(mian)(mian)(mian)積(ji)(ji)上也實(shi)現了0.75ｗ的(de)(de)(de)(de)(de)(de)(de)功(gong)(gong)率(lv)(lv)(lv)）。

    一般說來，太陽能面板的功率是越大越好，這樣在陽光下產生的電流大，能很快將其內置電池充滿。但現實中，需要在太陽能面板的功率和太陽能充電器的便攜性中找一個平衡點。一般說來，我們認為太陽能充電器的功率最小不能低于0.75w，（此功率的太陽能板在標準光強下有140ｍA的電流產生。在一般陽光下產生的電流在１００mA左右）如果低于此功率充電電流過小，基本上不會有明顯效果。 控制電路： 如果說太陽能面板是充電器的(de)(de)(de)前(qian)端部(bu)分，負責采(cai)集太(tai)(tai)陽能并將太(tai)(tai)陽能轉化為電(dian)(dian)能，那(nei)么控(kong)制(zhi)電(dian)(dian)路就是(shi)整個產品的(de)(de)(de)中樞(shu)。它主要(yao)承(cheng)擔兩(liang)方面的(de)(de)(de)功(gong)能：一是(shi)將前(qian)端產生的(de)(de)(de)電(dian)(dian)流(liu)盡(jin)可能儲(chu)存到(dao)內置電(dian)(dian)池(chi)而杜(du)絕或者將浪費減少到(dao)最低限度；二(er)是(shi)當充(chong)電(dian)(dian)器給手機等設(she)備(bei)充(chong)電(dian)(dian)時，盡(jin)可能多的(de)(de)(de)將內置電(dian)(dian)池(chi)里的(de)(de)(de)電(dian)(dian)量(liang)輸出給手機等設(she)備(bei)，而盡(jin)量(liang)少的(de)(de)(de)將電(dian)(dian)量(liang)損耗在線路上。

      遺憾的(de)(de)是(shi)，由于認知(zhi)或技術(shu)上(shang)的(de)(de)問題，目前(qian)(qian)國內(nei)廠商(shang)對(dui)太(tai)陽(yang)能(neng)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器控制電(dian)(dian)(dian)(dian)(dian)路設(she)計的(de)(de)優化(hua)沒有引起足(zu)夠的(de)(de)重視，導致生(sheng)產出來的(de)(de)太(tai)陽(yang)能(neng)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器實用性(xing)較差：前(qian)(qian)端產生(sheng)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流不能(neng)完(wan)全存(cun)(cun)儲到(dao)(dao)電(dian)(dian)(dian)(dian)(dian)池(chi)；內(nei)置電(dian)(dian)(dian)(dian)(dian)池(chi)給(gei)手機(ji)等(deng)設(she)備(bei)(bei)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時，很(hen)(hen)大一部分電(dian)(dian)(dian)(dian)(dian)流浪(lang)費在線(xian)路上(shang)，未能(neng)輸入到(dao)(dao)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)設(she)備(bei)(bei)上(shang)。 所以消費者在選(xuan)擇太(tai)陽(yang)能(neng)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器時，需要(yao)多留意一下(xia)這(zhe)兩(liang)個(ge)指標：二(er)次轉換率(lv)(lv)(lv)(lv)（前(qian)(qian)端產生(sheng)的(de)(de)電(dian)(dian)(dian)(dian)(dian)存(cun)(cun)儲到(dao)(dao)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)效(xiao)率(lv)(lv)(lv)(lv)）和放電(dian)(dian)(dian)(dian)(dian)效(xiao)率(lv)(lv)(lv)(lv)（內(nei)置電(dian)(dian)(dian)(dian)(dian)池(chi)里的(de)(de)電(dian)(dian)(dian)(dian)(dian)輸入到(dao)(dao)需要(yao)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)設(she)備(bei)(bei)上(shang)的(de)(de)效(xiao)率(lv)(lv)(lv)(lv)）。這(zhe)兩(liang)個(ge)效(xiao)率(lv)(lv)(lv)(lv)是(shi)越高越好。一般(ban)說(shuo)來，二(er)次存(cun)(cun)儲效(xiao)率(lv)(lv)(lv)(lv)目前(qian)(qian)做得很(hen)(hen)好的(de)(de)可以達(da)到(dao)(dao)９５％，放電(dian)(dian)(dian)(dian)(dian)效(xiao)率(lv)(lv)(lv)(lv)可以達(da)到(dao)(dao)８３％以上(shang)。

　　衡(heng)量控(kong)制(zhi)(zhi)電(dian)路(lu)(lu)好壞的另一個重要標準(zhun)是(shi)：控(kong)制(zhi)(zhi)電(dian)路(lu)(lu)是(shi)否(fou)做(zuo)了各(ge)種保(bao)(bao)(bao)護(hu)(hu)。通常來說，一款好的太陽能(neng)充電(dian)器，控(kong)制(zhi)(zhi)電(dian)路(lu)(lu)應該具備(bei)(bei)：過(guo)流(liu)保(bao)(bao)(bao)護(hu)(hu)（當(dang)(dang)電(dian)流(liu)過(guo)高時能(neng)自(zi)動(dong)限流(liu)，不會對充電(dian)設(she)備(bei)(bei)產生(sheng)(sheng)損(sun)害），過(guo)沖(chong)保(bao)(bao)(bao)護(hu)(hu)（當(dang)(dang)電(dian)池(chi)電(dian)量達(da)到設(she)定的限度時，將自(zi)動(dong)停(ting)止對電(dian)池(chi)的充電(dian)，從而杜絕(jue)電(dian)池(chi)損(sun)壞甚至爆炸的可能(neng)），過(guo)放保(bao)(bao)(bao)護(hu)(hu)（主要是(shi)用來保(bao)(bao)(bao)護(hu)(hu)電(dian)池(chi)，避免(mian)深度放電(dian)而對電(dian)池(chi)產生(sheng)(sheng)損(sun)害），溫(wen)度保(bao)(bao)(bao)護(hu)(hu)（當(dang)(dang)控(kong)制(zhi)(zhi)電(dian)路(lu)(lu)溫(wen)度超過(guo)設(she)定溫(wen)度，充電(dian)器將自(zi)動(dong)停(ting)止工(gong)作，以保(bao)(bao)(bao)護(hu)(hu)電(dian)池(chi)）。

      如果控制電路上這些保護都沒做或者大部分沒做的話，那將會把太陽能充電器的(de)質量風(feng)險轉嫁給(gei)需要充(chong)電的(de)手機(ji)等數碼設備，很(hen)有可(ke)能給(gei)消(xiao)費者(zhe)帶來損失。象我們(men)維勝特自己研發太陽能充(chong)電器時(shi)，首先想到(dao)的(de)就是安(an)全性如何保證。在(zai)這方面我們(men)下了很(hen)多功夫。所以消(xiao)費者(zhe)在(zai)購(gou)買太陽能充(chong)電器不(bu)要一味去看價格。盡管(guan)電路保護設計(ji)不(bu)健全的(de)充(chong)電器未必就一定會損害您充(chong)電的(de)設備，但(dan)花錢買個(ge)安(an)心還是有必要的(de)。
