1、待機狀態(tai)：
在如下幾種情況下會處理待機狀態：
a. 輸入電壓低于電路最低工作電壓。
b. 電池(chi)電壓充飽(bao)后。
c. 利用外(wai)置(zhi)開關(guan)強(qiang)行關(guan)斷(duan)IC，停止IC充電。
待機狀(zhuang)態(tai)的電壓電流(liu)特性：充(chong)電IC無充(chong)電電壓輸(shu)出，IC輸(shu)入(ru)電流(liu)在(zai)uA級，可以減小電路(lu)損(sun)耗。
2、預(yu)充(chong)(chong)狀態(tai)：如上圖(tu)所(suo)示。預(yu)充(chong)(chong)電時的最佳電流(liu)：即當(dang)鋰(li)(li)電池的初(chu)始(shi)/空(kong)載電壓低于預(yu)充(chong)(chong)電閾(yu)值(zhi)時，首先要經過一(yi)個預(yu)充(chong)(chong)電階段，就單(dan)個鋰(li)(li)離子(zi)電池而言，這個閾(yu)值(zhi)一(yi)般為3.0V，在此階段，預(yu)充(chong)(chong)電電流(liu)大(da)約為下(xia)一(yi)個階段——恒流(liu)充(chong)(chong)電階段電流(liu)的10%左右。
3、恒(heng)流(liu)充(chong)電(dian)(dian)狀態：如上圖所(suo)示最(zui)(zui)大(da)充(chong)電(dian)(dian)電(dian)(dian)流(liu)部分，在電(dian)(dian)池(chi)電(dian)(dian)壓(ya)(ya)已經大(da)于預設電(dian)(dian)壓(ya)(ya)閥值而小(xiao)于最(zui)(zui)高電(dian)(dian)壓(ya)(ya)4.2V時(shi)，此時(shi)IC將(jiang)以外掛電(dian)(dian)阻(zu)設定(ding)的最(zui)(zui)大(da)充(chong)電(dian)(dian)電(dian)(dian)流(liu)來給電(dian)(dian)池(chi)充(chong)電(dian)(dian)。將(jiang)電(dian)(dian)池(chi)電(dian)(dian)壓(ya)(ya)充(chong)到等(deng)于最(zui)(zui)大(da)充(chong)電(dian)(dian)電(dian)(dian)壓(ya)(ya)（4.2V附近）時(shi)為止。
。恒流(liu)(liu)充(chong)電(dian)(dian)時(shi)的(de)最佳電(dian)(dian)流(liu)(liu)：所(suo)謂恒流(liu)(liu)就是(shi)(shi)電(dian)(dian)流(liu)(liu)恒定，電(dian)(dian)壓(ya)逐漸(jian)升高，此時(shi)進(jin)入快(kuai)速充(chong)電(dian)(dian)階段。大多(duo)數(shu)的(de)恒流(liu)(liu)充(chong)電(dian)(dian)電(dian)(dian)流(liu)(liu)設定為(wei)(wei)0.5~0.8C之(zhi)(zhi)間，可以(yi)理(li)解為(wei)(wei)0.7C，也就是(shi)(shi)在不考慮其他因素的(de)情況(kuang)下，大約兩個小時(shi)可以(yi)充(chong)滿。之(zhi)(zhi)所(suo)以(yi)選擇0.7C，是(shi)(shi)因為(wei)(wei)這個電(dian)(dian)流(liu)(liu)很好地做(zuo)到了充(chong)電(dian)(dian)時(shi)間與(yu)充(chong)電(dian)(dian)安全性的(de)平(ping)衡。
恒(heng)流充電狀態時(shi)需要注意的幾個問題(ti)：
1. 在此狀態(tai)下，IC處于最大充電(dian)電(dian)流狀態(tai)，此時的損耗也是也是最大的。線性降壓的損耗計(ji)算＝(VIN-VOUT)×IOUT。此時需要注意IC的最高(gao)工作溫度。
2. 因為(wei)最高(gao)充(chong)電(dian)電(dian)流的造(zao)成溫升的提高(gao)，IC會自動降(jiang)低(di)最大充(chong)電(dian)流。這(zhe)就是在過熱時充(chong)電(dian)電(dian)流下降(jiang)的原因。
4、恒(heng)壓(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)(zhuang)態(tai)：如上圖所示最(zui)大(da)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)部分(fen)，當檢(jian)測到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)等于(yu)或者(zhe)接近(jin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)時(shi)。此(ci)時(shi)將(jiang)會以(yi)恒(heng)定(ding)4.2V充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，而(er)逐步降壓(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)方(fang)式。當檢(jian)測到充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)小于(yu)最(zui)大(da)設定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)1/10時(shi)，將(jiang)會停止充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。恒(heng)壓(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)：就(jiu)(jiu)(jiu)單節(jie)鋰(li)離(li)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)而(er)言，當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)達到一定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)值(zhi)時(shi)，即進入(ru)恒(heng)定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，這個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)值(zhi)一般為(wei)(wei)4.2V，在此(ci)階(jie)段，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)不變，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)減小；這種電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)減小是(shi)個(ge)依次遞減過程，大(da)多數的(de)鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)保(bao)護選擇(ze)0.1C為(wei)(wei)終止電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，這也就(jiu)(jiu)(jiu)意(yi)(yi)味著(zhu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程進入(ru)結束狀(zhuang)(zhuang)態(tai)。一旦充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)結束，則(ze)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)降為(wei)(wei)零。在此(ci)狀(zhuang)(zhuang)態(tai)下需要(yao)注意(yi)(yi)的(de)問(wen)題就(jiu)(jiu)(jiu)是(shi)：當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)大(da)最(zui)高設定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)時(shi)可(ke)以(yi)自動關斷，同(tong)時(shi)，當IC的(de)過壓(ya)(ya)保(bao)護點在非正(zheng)常電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)狀(zhuang)(zhuang)態(tai)下，可(ke)以(yi)自動鎖定(ding)。
鋰電(dian)池最佳充(chong)電(dian)電(dian)流(liu)的(de)(de)(de)核心是恒流(liu)充(chong)電(dian)時的(de)(de)(de)電(dian)流(liu)設計，這(zhe)里要強調的(de)(de)(de)是，大(da)(da)多數便捷式鋰電(dian)池較宜(yi)設計為0.5C~0.8C充(chong)電(dian)，如：iPhone的(de)(de)(de)1400mAh容量（容量mAh＝電(dian)流(liu)mA×時間(jian)h）的(de)(de)(de)電(dian)池為例，蘋(pin)果選(xuan)擇(ze)了0.7C，即蘋(pin)果充(chong)電(dian)電(dian)流(liu)多為1A左右，大(da)(da)部分的(de)(de)(de)電(dian)池在(zai)0.5C--0.8C之間(jian)你們可(ke)以(yi)選(xuan)擇(ze)了！
鋰(li)(li)電(dian)(dian)(dian)池最大充電(dian)(dian)(dian)電(dian)(dian)(dian)流嚴格說是由電(dian)(dian)(dian)池結構決(jue)定(ding)(ding)(ding)的，因而，各(ge)個(ge)鋰(li)(li)電(dian)(dian)(dian)池生產(chan)廠家對(dui)此規定(ding)(ding)(ding)并不一致，有的設定(ding)(ding)(ding)為0.6C，便攜式鋰(li)(li)電(dian)(dian)(dian)池最高的規定(ding)(ding)(ding)為1C。
當然也不能忽視預充電和恒壓充電的電流設計，這兩個過程中，如果初始電壓不低于預充電閾值3.0V，則不存在預充電過程。總的來說，在恒流充電過程前后有一個事前醞釀和運動休整的過程有利于鋰電池的長期使用。上海施能電器設備有限公司始建(jian)于(yu)1984年，上海市高新技術企業，中國工業車輛優秀配套供應商，上海電器行業名優產品，主要生產工頻系列充電機，高頻系列充電機，鋰電池充電機，系列放電機，系列充放電機等電器產品。
在如下幾種情況下會處理待機狀態：
a. 輸入電壓低于電路最低工作電壓。
b. 電池(chi)電壓充飽(bao)后。
c. 利用外(wai)置(zhi)開關(guan)強(qiang)行關(guan)斷(duan)IC，停止IC充電。
待機狀(zhuang)態(tai)的電壓電流(liu)特性：充(chong)電IC無充(chong)電電壓輸(shu)出，IC輸(shu)入(ru)電流(liu)在(zai)uA級，可以減小電路(lu)損(sun)耗。
2、預(yu)充(chong)(chong)狀態(tai)：如上圖(tu)所(suo)示。預(yu)充(chong)(chong)電時的最佳電流(liu)：即當(dang)鋰(li)(li)電池的初(chu)始(shi)/空(kong)載電壓低于預(yu)充(chong)(chong)電閾(yu)值(zhi)時，首先要經過一(yi)個預(yu)充(chong)(chong)電階段，就單(dan)個鋰(li)(li)離子(zi)電池而言，這個閾(yu)值(zhi)一(yi)般為3.0V，在此階段，預(yu)充(chong)(chong)電電流(liu)大(da)約為下(xia)一(yi)個階段——恒流(liu)充(chong)(chong)電階段電流(liu)的10%左右。
3、恒(heng)流(liu)充(chong)電(dian)(dian)狀態：如上圖所(suo)示最(zui)(zui)大(da)充(chong)電(dian)(dian)電(dian)(dian)流(liu)部分，在電(dian)(dian)池(chi)電(dian)(dian)壓(ya)(ya)已經大(da)于預設電(dian)(dian)壓(ya)(ya)閥值而小(xiao)于最(zui)(zui)高電(dian)(dian)壓(ya)(ya)4.2V時(shi)，此時(shi)IC將(jiang)以外掛電(dian)(dian)阻(zu)設定(ding)的最(zui)(zui)大(da)充(chong)電(dian)(dian)電(dian)(dian)流(liu)來給電(dian)(dian)池(chi)充(chong)電(dian)(dian)。將(jiang)電(dian)(dian)池(chi)電(dian)(dian)壓(ya)(ya)充(chong)到等(deng)于最(zui)(zui)大(da)充(chong)電(dian)(dian)電(dian)(dian)壓(ya)(ya)（4.2V附近）時(shi)為止。
。恒流(liu)(liu)充(chong)電(dian)(dian)時(shi)的(de)最佳電(dian)(dian)流(liu)(liu)：所(suo)謂恒流(liu)(liu)就是(shi)(shi)電(dian)(dian)流(liu)(liu)恒定，電(dian)(dian)壓(ya)逐漸(jian)升高，此時(shi)進(jin)入快(kuai)速充(chong)電(dian)(dian)階段。大多(duo)數(shu)的(de)恒流(liu)(liu)充(chong)電(dian)(dian)電(dian)(dian)流(liu)(liu)設定為(wei)(wei)0.5~0.8C之(zhi)(zhi)間，可以(yi)理(li)解為(wei)(wei)0.7C，也就是(shi)(shi)在不考慮其他因素的(de)情況(kuang)下，大約兩個小時(shi)可以(yi)充(chong)滿。之(zhi)(zhi)所(suo)以(yi)選擇0.7C，是(shi)(shi)因為(wei)(wei)這個電(dian)(dian)流(liu)(liu)很好地做(zuo)到了充(chong)電(dian)(dian)時(shi)間與(yu)充(chong)電(dian)(dian)安全性的(de)平(ping)衡。
恒(heng)流充電狀態時(shi)需要注意的幾個問題(ti)：
1. 在此狀態(tai)下，IC處于最大充電(dian)電(dian)流狀態(tai)，此時的損耗也是也是最大的。線性降壓的損耗計(ji)算＝(VIN-VOUT)×IOUT。此時需要注意IC的最高(gao)工作溫度。
2. 因為(wei)最高(gao)充(chong)電(dian)電(dian)流的造(zao)成溫升的提高(gao)，IC會自動降(jiang)低(di)最大充(chong)電(dian)流。這(zhe)就是在過熱時充(chong)電(dian)電(dian)流下降(jiang)的原因。
4、恒(heng)壓(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)(zhuang)態(tai)：如上圖所示最(zui)大(da)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)部分(fen)，當檢(jian)測到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)等于(yu)或者(zhe)接近(jin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)時(shi)。此(ci)時(shi)將(jiang)會以(yi)恒(heng)定(ding)4.2V充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，而(er)逐步降壓(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)方(fang)式。當檢(jian)測到充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)小于(yu)最(zui)大(da)設定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)1/10時(shi)，將(jiang)會停止充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。恒(heng)壓(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)：就(jiu)(jiu)(jiu)單節(jie)鋰(li)離(li)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)而(er)言，當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)達到一定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)值(zhi)時(shi)，即進入(ru)恒(heng)定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，這個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)值(zhi)一般為(wei)(wei)4.2V，在此(ci)階(jie)段，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)不變，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)減小；這種電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)減小是(shi)個(ge)依次遞減過程，大(da)多數的(de)鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)保(bao)護選擇(ze)0.1C為(wei)(wei)終止電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，這也就(jiu)(jiu)(jiu)意(yi)(yi)味著(zhu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程進入(ru)結束狀(zhuang)(zhuang)態(tai)。一旦充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)結束，則(ze)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)降為(wei)(wei)零。在此(ci)狀(zhuang)(zhuang)態(tai)下需要(yao)注意(yi)(yi)的(de)問(wen)題就(jiu)(jiu)(jiu)是(shi)：當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)大(da)最(zui)高設定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)時(shi)可(ke)以(yi)自動關斷，同(tong)時(shi)，當IC的(de)過壓(ya)(ya)保(bao)護點在非正(zheng)常電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)狀(zhuang)(zhuang)態(tai)下，可(ke)以(yi)自動鎖定(ding)。
鋰電(dian)池最佳充(chong)電(dian)電(dian)流(liu)的(de)(de)(de)核心是恒流(liu)充(chong)電(dian)時的(de)(de)(de)電(dian)流(liu)設計，這(zhe)里要強調的(de)(de)(de)是，大(da)(da)多數便捷式鋰電(dian)池較宜(yi)設計為0.5C~0.8C充(chong)電(dian)，如：iPhone的(de)(de)(de)1400mAh容量（容量mAh＝電(dian)流(liu)mA×時間(jian)h）的(de)(de)(de)電(dian)池為例，蘋(pin)果選(xuan)擇(ze)了0.7C，即蘋(pin)果充(chong)電(dian)電(dian)流(liu)多為1A左右，大(da)(da)部分的(de)(de)(de)電(dian)池在(zai)0.5C--0.8C之間(jian)你們可(ke)以(yi)選(xuan)擇(ze)了！
鋰(li)(li)電(dian)(dian)(dian)池最大充電(dian)(dian)(dian)電(dian)(dian)(dian)流嚴格說是由電(dian)(dian)(dian)池結構決(jue)定(ding)(ding)(ding)的，因而，各(ge)個(ge)鋰(li)(li)電(dian)(dian)(dian)池生產(chan)廠家對(dui)此規定(ding)(ding)(ding)并不一致，有的設定(ding)(ding)(ding)為0.6C，便攜式鋰(li)(li)電(dian)(dian)(dian)池最高的規定(ding)(ding)(ding)為1C。
當然也不能忽視預充電和恒壓充電的電流設計，這兩個過程中，如果初始電壓不低于預充電閾值3.0V，則不存在預充電過程。總的來說，在恒流充電過程前后有一個事前醞釀和運動休整的過程有利于鋰電池的長期使用。上海施能電器設備有限公司始建(jian)于(yu)1984年，上海市高新技術企業，中國工業車輛優秀配套供應商，上海電器行業名優產品，主要生產工頻系列充電機，高頻系列充電機，鋰電池充電機，系列放電機，系列充放電機等電器產品。
