現在太陽能充電器已經很常見了(le)，那么就(jiu)會(hui)有(you)更(geng)多人來關注太(tai)陽(yang)能(neng)(neng)充(chong)電(dian)(dian)(dian)器(qi)的(de)(de)性能(neng)(neng)問(wen)題(ti)。要評價一款太(tai)陽(yang)能(neng)(neng)充(chong)電(dian)(dian)(dian)器(qi)的(de)(de)性能(neng)(neng)，可以從下面三個(ge)方(fang)面來看(kan)：電(dian)(dian)(dian)池(chi)(chi)(chi)： 由(you)于太(tai)陽(yang)能(neng)(neng)充(chong)電(dian)(dian)(dian)器(qi)的(de)(de)使用環境跟普通(tong)的(de)(de)電(dian)(dian)(dian)子產品(pin)有(you)所不(bu)同(tong)，所以太(tai)陽(yang)能(neng)(neng)充(chong)電(dian)(dian)(dian)器(qi)對內(nei)置電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)要求也最高(gao)。但(dan)這(zhe)(zhe)恰恰是消費(fei)者容易(yi)忽略的(de)(de)地方(fang)，同(tong)時也是一些缺(que)乏社會(hui)責任感(gan)的(de)(de)廠家容易(yi)做手腳的(de)(de)地方(fang)。在市面上(shang)，一塊同(tong)樣容量的(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)價格可能(neng)(neng)相差(cha)好幾倍，所以，某(mou)些山寨廠商就(jiu)瞄準了(le)這(zhe)(zhe)塊的(de)(de)暴利，很多非常廉價的(de)(de)充(chong)電(dian)(dian)(dian)器(qi)使用的(de)(de)都是二(er)次電(dian)(dian)(dian)芯翻(fan)新后的(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)，好點的(de)(de)就(jiu)是用電(dian)(dian)(dian)池(chi)(chi)(chi)里的(de)(de)B品(pin)、C品(pin)的(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)。這(zhe)(zhe)樣的(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)使用壽命短不(bu)說，還有(you)可能(neng)(neng)給消費(fei)者帶來人身(shen)安全上(shang)的(de)(de)風險。

    太陽能充電器的(de)內置電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)應以鋰(li)聚(ju)合物(wu)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)為佳(jia)，相對于平時我(wo)們常(chang)見的(de)鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)（液(ye)態鋰(li)離子(zi)），聚(ju)合物(wu)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)鋰(li)離子(zi)成膠(jiao)體裝，活(huo)躍(yue)程度遠小于液(ye)態鋰(li)離子(zi)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，因此不(bu)會產(chan)生爆炸。并且為適用(yong)太(tai)陽能充電(dian)(dian)(dian)器的(de)使(shi)用(yong)環(huan)境，聚(ju)合物(wu)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)最好(hao)經過高溫處理，提升電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)耐高溫極(ji)限(xian)。 最后，需要注意的(de)是外(wai)殼表面處理和它(ta)的(de)各種附件。市面上常(chang)見的(de)太(tai)陽能充電(dian)(dian)(dian)器以塑膠(jiao)殼為主，外(wai)表處理主要有亮(liang)油、橡膠(jiao)漆，UV。亮(liang)油價(jia)格比(bi)較便(bian)宜，同時表面容易出現劃痕。橡膠(jiao)漆手(shou)感非(fei)常(chang)舒適，但隨使(shi)用(yong)時間(jian)的(de)增加會掉漆。UV一般只在(zai)高檔品牌手(shou)機上才使(shi)用(yong)，價(jia)格昂(ang)貴。

     采(cai)用(yong)(yong)UV處理，產(chan)品表(biao)面(mian)(mian)(mian)(mian)光(guang)潔精細(xi)，同時(shi)硬度(du)好，不(bu)掉漆，不(bu)會(hui)留劃痕。 如果太(tai)(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)充電(dian)(dian)(dian)(dian)器有配DC適配器，多(duo)關(guan)(guan)注(zhu)一下(xia)(xia)DC適配器的(de)(de)(de)(de)質量是(shi)有必要(yao)的(de)(de)(de)(de)。畢竟(jing)這關(guan)(guan)系到產(chan)品和(he)(he)人身安(an)全。太(tai)(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)板(ban)： 目前市面(mian)(mian)(mian)(mian)上的(de)(de)(de)(de)太(tai)(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)分為非(fei)晶硅(gui)(gui)和(he)(he)晶體硅(gui)(gui)。其(qi)中晶體硅(gui)(gui)又可(ke)分為多(duo)晶硅(gui)(gui)和(he)(he)單晶硅(gui)(gui)。從三種(zhong)材料(liao)的(de)(de)(de)(de)光(guang)電(dian)(dian)(dian)(dian)轉換效率來(lai)看是(shi)：單晶硅(gui)(gui)（最高可(ke)達(da)１７％）>多(duo)晶硅(gui)(gui)（１２～１５％）>非(fei)晶硅(gui)(gui)（５％　左右）。但(dan)(dan)晶體硅(gui)(gui)（單晶硅(gui)(gui)和(he)(he)多(duo)晶硅(gui)(gui)）的(de)(de)(de)(de)在弱(ruo)(ruo)光(guang)下(xia)(xia)基本上不(bu)會(hui)有電(dian)(dian)(dian)(dian)流(liu)產(chan)生，非(fei)晶硅(gui)(gui)弱(ruo)(ruo)光(guang)型好（在弱(ruo)(ruo)光(guang)下(xia)(xia)能(neng)(neng)(neng)(neng)量本來(lai)就很(hen)少）。所以綜合看來(lai)，宜用(yong)(yong)單晶硅(gui)(gui)或多(duo)晶硅(gui)(gui)作太(tai)(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)(de)材料(liao)。 接下(xia)(xia)來(lai)我(wo)們要(yao)關(guan)(guan)注(zhu)的(de)(de)(de)(de)重點就是(shi)太(tai)(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)板(ban)的(de)(de)(de)(de)功率，一般說來(lai)，太(tai)(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)板(ban)的(de)(de)(de)(de)功率跟太(tai)(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)晶片(pian)的(de)(de)(de)(de)面(mian)(mian)(mian)(mian)積(ji)成正比（太(tai)(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)晶片(pian)的(de)(de)(de)(de)面(mian)(mian)(mian)(mian)積(ji)不(bu)完(wan)全等同于(yu)太(tai)(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)封裝面(mian)(mian)(mian)(mian)板(ban)的(de)(de)(de)(de)面(mian)(mian)(mian)(mian)積(ji)，因為有的(de)(de)(de)(de)太(tai)(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)面(mian)(mian)(mian)(mian)板(ban)雖(sui)然大(da)，但(dan)(dan)太(tai)(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)晶片(pian)排列(lie)的(de)(de)(de)(de)縫隙很(hen)寬，這樣的(de)(de)(de)(de)太(tai)(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)面(mian)(mian)(mian)(mian)板(ban)功率不(bu)一定高。比如我(wo)們的(de)(de)(de)(de)VSC－０３雖(sui)然太(tai)(tai)(tai)陽(yang)能(neng)(neng)(neng)(neng)面(mian)(mian)(mian)(mian)板(ban)不(bu)大(da)，但(dan)(dan)晶片(pian)排列(lie)緊密，在比較小的(de)(de)(de)(de)面(mian)(mian)(mian)(mian)積(ji)上也實現了0.75ｗ的(de)(de)(de)(de)功率）。

    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前端(duan)部分，負責采(cai)集太陽能(neng)(neng)(neng)(neng)并將太陽能(neng)(neng)(neng)(neng)轉(zhuan)化為電(dian)(dian)(dian)(dian)能(neng)(neng)(neng)(neng)，那(nei)么控制電(dian)(dian)(dian)(dian)路(lu)就是整(zheng)個產品的中樞。它主要承擔兩方面的功能(neng)(neng)(neng)(neng)：一(yi)是將前端(duan)產生的電(dian)(dian)(dian)(dian)流盡可能(neng)(neng)(neng)(neng)儲存到內(nei)置電(dian)(dian)(dian)(dian)池(chi)而杜絕或(huo)者將浪費減少到最低(di)限度；二是當充(chong)電(dian)(dian)(dian)(dian)器給手機等(deng)設(she)備(bei)充(chong)電(dian)(dian)(dian)(dian)時，盡可能(neng)(neng)(neng)(neng)多的將內(nei)置電(dian)(dian)(dian)(dian)池(chi)里的電(dian)(dian)(dian)(dian)量輸出給手機等(deng)設(she)備(bei)，而盡量少的將電(dian)(dian)(dian)(dian)量損耗在線路(lu)上(shang)。

      遺憾的是，由于(yu)認知或技術上的問(wen)題，目前(qian)國內(nei)(nei)廠商(shang)對太(tai)陽(yang)能充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)控(kong)制電(dian)(dian)(dian)(dian)(dian)路設計的優化沒有(you)引起足夠的重視，導致(zhi)生(sheng)(sheng)產出(chu)來(lai)的太(tai)陽(yang)能充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)實(shi)用(yong)性較差：前(qian)端產生(sheng)(sheng)的電(dian)(dian)(dian)(dian)(dian)流(liu)不能完全(quan)存(cun)儲(chu)到(dao)(dao)(dao)電(dian)(dian)(dian)(dian)(dian)池；內(nei)(nei)置(zhi)電(dian)(dian)(dian)(dian)(dian)池給手機等設備(bei)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時，很(hen)大一(yi)部分電(dian)(dian)(dian)(dian)(dian)流(liu)浪費(fei)在(zai)線路上，未(wei)能輸入到(dao)(dao)(dao)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)設備(bei)上。 所以(yi)消費(fei)者(zhe)在(zai)選擇太(tai)陽(yang)能充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)時，需要多留(liu)意一(yi)下這(zhe)兩個指標：二次轉換率(lv)（前(qian)端產生(sheng)(sheng)的電(dian)(dian)(dian)(dian)(dian)存(cun)儲(chu)到(dao)(dao)(dao)電(dian)(dian)(dian)(dian)(dian)池的效率(lv)）和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)效率(lv)（內(nei)(nei)置(zhi)電(dian)(dian)(dian)(dian)(dian)池里的電(dian)(dian)(dian)(dian)(dian)輸入到(dao)(dao)(dao)需要充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)設備(bei)上的效率(lv)）。這(zhe)兩個效率(lv)是越高越好(hao)。一(yi)般(ban)說來(lai)，二次存(cun)儲(chu)效率(lv)目前(qian)做得很(hen)好(hao)的可以(yi)達到(dao)(dao)(dao)９５％，放(fang)電(dian)(dian)(dian)(dian)(dian)效率(lv)可以(yi)達到(dao)(dao)(dao)８３％以(yi)上。

　　衡量控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)好壞的(de)另一個重要(yao)(yao)標準(zhun)是：控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)是否做了各(ge)種保(bao)護(hu)(hu)。通常來(lai)說，一款好的(de)太陽能充電(dian)(dian)(dian)(dian)(dian)(dian)器，控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)應該具備：過(guo)(guo)流(liu)(liu)保(bao)護(hu)(hu)（當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)過(guo)(guo)高時能自(zi)(zi)動限流(liu)(liu)，不(bu)會(hui)對充電(dian)(dian)(dian)(dian)(dian)(dian)設(she)備產生損害(hai)），過(guo)(guo)沖保(bao)護(hu)(hu)（當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)量達到設(she)定(ding)的(de)限度時，將自(zi)(zi)動停止對電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)充電(dian)(dian)(dian)(dian)(dian)(dian)，從而杜(du)絕電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)損壞甚至爆(bao)炸的(de)可(ke)能），過(guo)(guo)放保(bao)護(hu)(hu)（主(zhu)要(yao)(yao)是用(yong)來(lai)保(bao)護(hu)(hu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，避免深度放電(dian)(dian)(dian)(dian)(dian)(dian)而對電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)產生損害(hai)），溫(wen)(wen)(wen)度保(bao)護(hu)(hu)（當(dang)控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)溫(wen)(wen)(wen)度超過(guo)(guo)設(she)定(ding)溫(wen)(wen)(wen)度，充電(dian)(dian)(dian)(dian)(dian)(dian)器將自(zi)(zi)動停止工(gong)作，以保(bao)護(hu)(hu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(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質(zhi)量風險轉(zhuan)嫁(jia)給需(xu)要充(chong)電(dian)(dian)的手(shou)機等(deng)數(shu)碼設(she)備，很(hen)有可能給消費(fei)者帶來損失(shi)。象(xiang)我(wo)們(men)(men)維勝特(te)自己研(yan)發太陽(yang)能充(chong)電(dian)(dian)器時(shi)，首先想到的就(jiu)是安(an)全性如何(he)保證。在(zai)這方面(mian)我(wo)們(men)(men)下(xia)了很(hen)多功(gong)夫(fu)。所以消費(fei)者在(zai)購買太陽(yang)能充(chong)電(dian)(dian)器不要一味去看價格。盡管(guan)電(dian)(dian)路保護設(she)計(ji)不健全的充(chong)電(dian)(dian)器未必就(jiu)一定會損害您充(chong)電(dian)(dian)的設(she)備，但花錢買個安(an)心還是有必要的。
