20世纪(ji)80年(nian)代首次推出(chu)的充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)器芯片，由于化学物质电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)难(nan)以充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)，简(jian)(jian)化了(le)NiCd和NiMH充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)器的设计。锂(li)离子电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)更(geng)简(jian)(jian)单，而(er)且大多(duo)数现代充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)芯片还(hai)包括为锂(li)离子电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)安全充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)所需的保护电(dian)(dian)(dian)(dian)(dian)路，其他(ta)包括电(dian)(dian)(dian)(dian)(dian)流(liu)和电(dian)(dian)(dian)(dian)(dian)压调整，FET开关，一(yi)些充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)状态指(zhi)示灯和电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)平衡(heng)。

一般充(chong)电(dian)(dian)(dian)(dian)芯(xin)片具有(you)超时(shi)计(ji)时(shi)器，如(ru)果在充(chong)电(dian)(dian)(dian)(dian)过(guo)程中没有(you)出现预期的(de)可预测症状，则会停止为有(you)缺陷的(de)锂电(dian)(dian)(dian)(dian)池充(chong)电(dian)(dian)(dian)(dian)。芯(xin)片还具有(you)充(chong)电(dian)(dian)(dian)(dian)前(qian)调整功(gong)能，以(yi)唤醒(xing)不活跃(yue)的(de)电(dian)(dian)(dian)(dian)池，并在电(dian)(dian)(dian)(dian)池存储时(shi)减少电(dian)(dian)(dian)(dian)路的(de)管理电(dian)(dian)(dian)(dian)流的(de)睡眠模式。

虽然充(chong)电(dian)(dian)器(qi)(qi)芯(xin)片(pian)(pian)(pian)简单且(qie)经济(ji)，但它(ta)们也有局(ju)限性。大多数算法(fa)都(dou)提供(gong)(gong)固定成(cheng)(cheng)本(ben)的(de)算法(fa)，不(bu)(bu)允许针对特殊(shu)用(yong)(yong)途进行微(wei)调。芯(xin)片(pian)(pian)(pian)是(shi)为给定的(de)电(dian)(dian)池制(zhi)(zhi)造的(de)，不(bu)(bu)能满足用(yong)(yong)户(hu)对不(bu)(bu)同化学成(cheng)(cheng)分的(de)要求，或读(du)取(qu)可嵌入在(zai)电(dian)(dian)池座(zuo)中的(de)电(dian)(dian)池代码(ma)。在(zai)给老化的(de)电(dian)(dian)池充(chong)电(dian)(dian)时(shi)(shi)，大多数芯(xin)片(pian)(pian)(pian)也不(bu)(bu)会调整(zheng)到(dao)佳充(chong)电(dian)(dian)电(dian)(dian)流(liu)。微(wei)控(kong)制(zhi)(zhi)器(qi)(qi)提供(gong)(gong)了充(chong)电(dian)(dian)器(qi)(qi)芯(xin)片(pian)(pian)(pian)的(de)替(ti)代品。由于需要额外的(de)编程时(shi)(shi)间，设计成(cheng)(cheng)本(ben)更高，但制(zhi)(zhi)造成(cheng)(cheng)本(ben)与(yu)充(chong)电(dian)(dian)器(qi)(qi)芯(xin)片(pian)(pian)(pian)兼容。充(chong)电(dian)(dian)芯(xin)片(pian)(pian)(pian)或微(wei)控(kong)制(zhi)(zhi)器(qi)(qi)只构成(cheng)(cheng)充(chong)电(dian)(dian)器(qi)(qi)电(dian)(dian)路的(de)一小部分，锂(li)电(dian)(dian)池大部分成(cheng)(cheng)本(ben)是(shi)在(zai)外围组件，包括固态开关、灯和电(dian)(dian)源。部分成(cheng)(cheng)本(ben)与(yu)瓦数直(zhi)接相关。
