1、待機狀態：
在如下(xia)幾種情(qing)況下(xia)會處理待機狀態(tai)：
a. 輸(shu)入電壓(ya)低于電路最低工作電壓(ya)。
b. 電池電壓充飽后。
c. 利用外(wai)置開關(guan)強(qiang)行關(guan)斷IC，停止IC充(chong)電。
待機狀(zhuang)態的電(dian)壓(ya)電(dian)流特性：充(chong)電(dian)IC無充(chong)電(dian)電(dian)壓(ya)輸出，IC輸入電(dian)流在uA級(ji)，可以減小電(dian)路損耗(hao)。
2、預(yu)充狀態：如上圖所示(shi)。預(yu)充電(dian)(dian)(dian)時的最佳(jia)電(dian)(dian)(dian)流：即當鋰電(dian)(dian)(dian)池的初(chu)始/空載電(dian)(dian)(dian)壓低(di)于預(yu)充電(dian)(dian)(dian)閾(yu)值時，首(shou)先要經(jing)過一個(ge)(ge)預(yu)充電(dian)(dian)(dian)階段(duan)，就單個(ge)(ge)鋰離子電(dian)(dian)(dian)池而言，這個(ge)(ge)閾(yu)值一般為3.0V，在此階段(duan)，預(yu)充電(dian)(dian)(dian)電(dian)(dian)(dian)流大約為下一個(ge)(ge)階段(duan)——恒流充電(dian)(dian)(dian)階段(duan)電(dian)(dian)(dian)流的10%左(zuo)右。
3、恒流充電(dian)(dian)(dian)(dian)(dian)(dian)狀態(tai)：如上圖所示最(zui)大充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流部分，在電(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)已經大于(yu)預設電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)閥值而(er)小于(yu)最(zui)高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)4.2V時(shi)(shi)，此時(shi)(shi)IC將(jiang)以外掛電(dian)(dian)(dian)(dian)(dian)(dian)阻設定的最(zui)大充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流來給電(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)。將(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)充到等于(yu)最(zui)大充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)（4.2V附近）時(shi)(shi)為止。
。恒流充(chong)電(dian)時的(de)(de)(de)最佳電(dian)流：所(suo)謂恒流就(jiu)是(shi)電(dian)流恒定，電(dian)壓逐漸升高(gao)，此時進入(ru)快速充(chong)電(dian)階段。大多數的(de)(de)(de)恒流充(chong)電(dian)電(dian)流設定為(wei)(wei)0.5~0.8C之(zhi)間(jian)，可以(yi)理解為(wei)(wei)0.7C，也(ye)就(jiu)是(shi)在不考慮其(qi)他因素的(de)(de)(de)情況下，大約(yue)兩(liang)個小時可以(yi)充(chong)滿。之(zhi)所(suo)以(yi)選擇0.7C，是(shi)因為(wei)(wei)這個電(dian)流很好地(di)做(zuo)到(dao)了充(chong)電(dian)時間(jian)與充(chong)電(dian)安全性的(de)(de)(de)平衡。
恒(heng)流充電狀(zhuang)態時需要注意的幾個(ge)問題：
1. 在此狀(zhuang)態下，IC處(chu)于(yu)最大(da)充(chong)電電流狀(zhuang)態，此時的損(sun)耗也(ye)是也(ye)是最大(da)的。線性降壓的損(sun)耗計算＝(VIN-VOUT)×IOUT。此時需(xu)要注意IC的最高工作溫(wen)度。
2. 因(yin)為最高(gao)充電(dian)電(dian)流的(de)造成(cheng)溫升的(de)提高(gao)，IC會自動降低最大充電(dian)流。這就(jiu)是在過(guo)熱時充電(dian)電(dian)流下降的(de)原因(yin)。
4、恒(heng)壓(ya)(ya)(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀態：如上圖所示最大充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)部分，當(dang)檢測到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)等于或者接近電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)時(shi)(shi)。此時(shi)(shi)將會(hui)以恒(heng)定(ding)(ding)4.2V充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，而(er)逐步降壓(ya)(ya)(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)方(fang)式。當(dang)檢測到充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流小于最大設(she)定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)1/10時(shi)(shi)，將會(hui)停止充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。恒(heng)壓(ya)(ya)(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流：就單節鋰離子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)而(er)言，當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)達(da)到一定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)值時(shi)(shi)，即(ji)進(jin)入恒(heng)定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，這(zhe)(zhe)(zhe)個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)值一般為(wei)4.2V，在(zai)此階段(duan)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)不變，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流減小；這(zhe)(zhe)(zhe)種(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流減小是個依次遞減過程，大多數(shu)的(de)(de)(de)鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)保(bao)護選擇0.1C為(wei)終止電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，這(zhe)(zhe)(zhe)也(ye)就意味著(zhu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程進(jin)入結束狀態。一旦充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)結束，則充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流降為(wei)零(ling)。在(zai)此狀態下(xia)需要(yao)注意的(de)(de)(de)問題就是：當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)大最高(gao)設(she)定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)時(shi)(shi)可以自動關斷，同時(shi)(shi)，當(dang)IC的(de)(de)(de)過壓(ya)(ya)(ya)(ya)保(bao)護點在(zai)非正常電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)狀態下(xia)，可以自動鎖(suo)定(ding)(ding)。
鋰電(dian)(dian)(dian)池(chi)最佳充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流的(de)(de)核心是恒流充(chong)(chong)電(dian)(dian)(dian)時(shi)的(de)(de)電(dian)(dian)(dian)流設計，這里要強(qiang)調的(de)(de)是，大多(duo)數便捷式鋰電(dian)(dian)(dian)池(chi)較宜設計為0.5C~0.8C充(chong)(chong)電(dian)(dian)(dian)，如：iPhone的(de)(de)1400mAh容量(liang)（容量(liang)mAh＝電(dian)(dian)(dian)流mA×時(shi)間h）的(de)(de)電(dian)(dian)(dian)池(chi)為例，蘋果選(xuan)擇了0.7C，即蘋果充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流多(duo)為1A左(zuo)右，大部分的(de)(de)電(dian)(dian)(dian)池(chi)在0.5C--0.8C之(zhi)間你們可以選(xuan)擇了！
鋰電池(chi)(chi)(chi)最大充電電流嚴格說(shuo)是由電池(chi)(chi)(chi)結(jie)構決定(ding)的(de)，因而，各個鋰電池(chi)(chi)(chi)生產廠家對此規定(ding)并(bing)不一致，有的(de)設定(ding)為0.6C，便攜式(shi)鋰電池(chi)(chi)(chi)最高的(de)規定(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(hai)施(shi)能電器(qi)設(she)備有限公(gong)司始(shi)建于1984年(nian)，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(xia)幾種情(qing)況下(xia)會處理待機狀態(tai)：
a. 輸(shu)入電壓(ya)低于電路最低工作電壓(ya)。
b. 電池電壓充飽后。
c. 利用外(wai)置開關(guan)強(qiang)行關(guan)斷IC，停止IC充(chong)電。
待機狀(zhuang)態的電(dian)壓(ya)電(dian)流特性：充(chong)電(dian)IC無充(chong)電(dian)電(dian)壓(ya)輸出，IC輸入電(dian)流在uA級(ji)，可以減小電(dian)路損耗(hao)。
2、預(yu)充狀態：如上圖所示(shi)。預(yu)充電(dian)(dian)(dian)時的最佳(jia)電(dian)(dian)(dian)流：即當鋰電(dian)(dian)(dian)池的初(chu)始/空載電(dian)(dian)(dian)壓低(di)于預(yu)充電(dian)(dian)(dian)閾(yu)值時，首(shou)先要經(jing)過一個(ge)(ge)預(yu)充電(dian)(dian)(dian)階段(duan)，就單個(ge)(ge)鋰離子電(dian)(dian)(dian)池而言，這個(ge)(ge)閾(yu)值一般為3.0V，在此階段(duan)，預(yu)充電(dian)(dian)(dian)電(dian)(dian)(dian)流大約為下一個(ge)(ge)階段(duan)——恒流充電(dian)(dian)(dian)階段(duan)電(dian)(dian)(dian)流的10%左(zuo)右。
3、恒流充電(dian)(dian)(dian)(dian)(dian)(dian)狀態(tai)：如上圖所示最(zui)大充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流部分，在電(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)已經大于(yu)預設電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)閥值而(er)小于(yu)最(zui)高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)4.2V時(shi)(shi)，此時(shi)(shi)IC將(jiang)以外掛電(dian)(dian)(dian)(dian)(dian)(dian)阻設定的最(zui)大充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流來給電(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)。將(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)充到等于(yu)最(zui)大充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)（4.2V附近）時(shi)(shi)為止。
。恒流充(chong)電(dian)時的(de)(de)(de)最佳電(dian)流：所(suo)謂恒流就(jiu)是(shi)電(dian)流恒定，電(dian)壓逐漸升高(gao)，此時進入(ru)快速充(chong)電(dian)階段。大多數的(de)(de)(de)恒流充(chong)電(dian)電(dian)流設定為(wei)(wei)0.5~0.8C之(zhi)間(jian)，可以(yi)理解為(wei)(wei)0.7C，也(ye)就(jiu)是(shi)在不考慮其(qi)他因素的(de)(de)(de)情況下，大約(yue)兩(liang)個小時可以(yi)充(chong)滿。之(zhi)所(suo)以(yi)選擇0.7C，是(shi)因為(wei)(wei)這個電(dian)流很好地(di)做(zuo)到(dao)了充(chong)電(dian)時間(jian)與充(chong)電(dian)安全性的(de)(de)(de)平衡。
恒(heng)流充電狀(zhuang)態時需要注意的幾個(ge)問題：
1. 在此狀(zhuang)態下，IC處(chu)于(yu)最大(da)充(chong)電電流狀(zhuang)態，此時的損(sun)耗也(ye)是也(ye)是最大(da)的。線性降壓的損(sun)耗計算＝(VIN-VOUT)×IOUT。此時需(xu)要注意IC的最高工作溫(wen)度。
2. 因(yin)為最高(gao)充電(dian)電(dian)流的(de)造成(cheng)溫升的(de)提高(gao)，IC會自動降低最大充電(dian)流。這就(jiu)是在過(guo)熱時充電(dian)電(dian)流下降的(de)原因(yin)。
4、恒(heng)壓(ya)(ya)(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀態：如上圖所示最大充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)部分，當(dang)檢測到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)等于或者接近電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)時(shi)(shi)。此時(shi)(shi)將會(hui)以恒(heng)定(ding)(ding)4.2V充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，而(er)逐步降壓(ya)(ya)(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)方(fang)式。當(dang)檢測到充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流小于最大設(she)定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)1/10時(shi)(shi)，將會(hui)停止充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。恒(heng)壓(ya)(ya)(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流：就單節鋰離子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)而(er)言，當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)達(da)到一定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)值時(shi)(shi)，即(ji)進(jin)入恒(heng)定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，這(zhe)(zhe)(zhe)個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)值一般為(wei)4.2V，在(zai)此階段(duan)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)不變，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流減小；這(zhe)(zhe)(zhe)種(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流減小是個依次遞減過程，大多數(shu)的(de)(de)(de)鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)保(bao)護選擇0.1C為(wei)終止電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，這(zhe)(zhe)(zhe)也(ye)就意味著(zhu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程進(jin)入結束狀態。一旦充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)結束，則充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流降為(wei)零(ling)。在(zai)此狀態下(xia)需要(yao)注意的(de)(de)(de)問題就是：當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)大最高(gao)設(she)定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)時(shi)(shi)可以自動關斷，同時(shi)(shi)，當(dang)IC的(de)(de)(de)過壓(ya)(ya)(ya)(ya)保(bao)護點在(zai)非正常電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)狀態下(xia)，可以自動鎖(suo)定(ding)(ding)。
鋰電(dian)(dian)(dian)池(chi)最佳充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流的(de)(de)核心是恒流充(chong)(chong)電(dian)(dian)(dian)時(shi)的(de)(de)電(dian)(dian)(dian)流設計，這里要強(qiang)調的(de)(de)是，大多(duo)數便捷式鋰電(dian)(dian)(dian)池(chi)較宜設計為0.5C~0.8C充(chong)(chong)電(dian)(dian)(dian)，如：iPhone的(de)(de)1400mAh容量(liang)（容量(liang)mAh＝電(dian)(dian)(dian)流mA×時(shi)間h）的(de)(de)電(dian)(dian)(dian)池(chi)為例，蘋果選(xuan)擇了0.7C，即蘋果充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流多(duo)為1A左(zuo)右，大部分的(de)(de)電(dian)(dian)(dian)池(chi)在0.5C--0.8C之(zhi)間你們可以選(xuan)擇了！
鋰電池(chi)(chi)(chi)最大充電電流嚴格說(shuo)是由電池(chi)(chi)(chi)結(jie)構決定(ding)的(de)，因而，各個鋰電池(chi)(chi)(chi)生產廠家對此規定(ding)并(bing)不一致，有的(de)設定(ding)為0.6C，便攜式(shi)鋰電池(chi)(chi)(chi)最高的(de)規定(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(hai)施(shi)能電器(qi)設(she)備有限公(gong)司始(shi)建于1984年(nian)，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。
