為什么電源適配器需要做老化測試(shi)
當然使用一(yi)年或者更久出(chu)現問(wen)題(ti)，那(nei)是(shi)(shi)電源的壽命問(wen)題(ti)，這個是(shi)(shi)沒(mei)有辦法控制的。當然這個問(wen)題(ti)也(ye)不能說(shuo)的如(ru)此***，我們分析是(shi)(shi)只(zhi)是(shi)(shi)理論上(shang)的結果(guo)，因為不排除(chu)你買到了山寨產品沒(mei)有做過老化測試(shi)的，但是(shi)(shi)使用起來(lai)就是(shi)(shi)沒(mei)問(wen)題(ti)，或許用個一(yi)年兩年的才出(chu)現問(wen)題(ti)，但是(shi)(shi)做過老化測試(shi)的電源適配器產品更加(jia)安(an)全一(yi)點。

四種(zhong)常見(jian)的電動(dong)車(che)充電方(fang)式
恒壓充(chong)電(dian)(dian)(dian)是指(zhi)每只單體電(dian)(dian)(dian)池(chi)均以某一恒定電(dian)(dian)(dian)壓(一般取單格電(dian)(dian)(dian)池(chi)數(shu)×2.5V)進(jin)行充(chong)電(dian)(dian)(dian)。其主(zhu)要特點為：充(chong)電(dian)(dian)(dian)初期電(dian)(dian)(dian)流相(xiang)(xiang)當大，蓄電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)動勢和電(dian)(dian)(dian)解(jie)液相(xiang)(xiang)對(dui)密度上(shang)升較快，隨著充(chong)電(dian)(dian)(dian)的(de)延(yan)續充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流逐(zhu)漸減小，在(zai)充(chong)電(dian)(dian)(dian)終期只有很小的(de)電(dian)(dian)(dian)流通過(guo);充(chong)電(dian)(dian)(dian)時(shi)間短、能(neng)耗低(di)

影響鋰電池循環性能的(de)因(yin)素
過多的(de)(de)水分(fen)會與(yu)正(zheng)負極活性物質發生副反應、破(po)壞其結構進而影響循環(huan)，同(tong)時水分(fen)過多也不利于SEI膜(mo)的(de)(de)形成，但(dan)在痕(hen)量(liang)的(de)(de)水分(fen)難以除去的(de)(de)同(tong)時，痕(hen)量(liang)的(de)(de)水也可(ke)以一定程度(du)上保(bao)證電芯的(de)(de)性能(neng)。
