鋰離子電池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)和(he)(he)系統(tong)(tong)控制架構是最大(da)(da)化電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)容量(liang)和(he)(he)最小化電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)間(jian)的(de)重要部分。在(zai)本文中，我們首先討(tao)論鋰離(li)子電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)算法，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)容量(liang)和(he)(he)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)壽命(ming)之(zhi)間(jian)的(de)權(quan)衡。我們還(huan)將討(tao)論電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)系統(tong)(tong)與充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)的(de)相互作用，例如電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)故障定時(shi)器(qi)的(de)結(jie)束(shu)，并描述(shu)動(dong)態電(dian)(dian)(dian)(dian)(dian)源(yuan)路徑管理（DPPM）技(ji)術。DPPM電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)為(wei)系統(tong)(tong)和(he)(he)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)提供獨立的(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)路徑，允許充(chong)(chong)分利(li)用適配器(qi)的(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)，同時(shi)最大(da)(da)限度地縮(suo)短(duan)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)間(jian)。它還(huan)可(ke)以在(zai)為(wei)系統(tong)(tong)供電(dian)(dian)(dian)(dian)(dian)時(shi)防止系統(tong)(tong)崩潰并為(wei)放(fang)電(dian)(dian)(dian)(dian)(dian)的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。

問：電池充電速度越快，電池壽命越短？

這是因(yin)為當(dang)充電(dian)速率為1C或(huo)更高時，額外(wai)的鋰(li)(li)離子(zi)從陽極變為金屬鋰(li)(li)。由于(yu)金屬鋰(li)(li)是活(huo)性材料(liao)，它(ta)容易與電(dian)解質(zhi)溶液反(fan)應，并(bing)且鋰(li)(li)永(yong)久(jiu)地損失。因(yin)此，電(dian)池充電(dian)率小于(yu)1C。

電池充電器和系統互動的原理

電(dian)池(chi)充電(dian)輸(shu)出也(ye)為(wei)系統(tong)供(gong)電(dian)，因此(ci)架構簡單，成本低。但是(shi)，當系統(tong)負載連(lian)接到電(dian)池(chi)時，會出現許多問(wen)題，例如電(dian)池(chi)充電(dian)時間延遲(chi)，充電(dian)終(zhong)止(zhi)，故障(zhang)安全定(ding)時器警告等。

在這種配置中，充(chong)(chong)電(dian)(dian)器(qi)的(de)輸(shu)出電(dian)(dian)流I CHG在系(xi)統和充(chong)(chong)電(dian)(dian)器(qi)之(zhi)間共(gong)享(xiang)，而不(bu)僅僅是(shi)(shi)電(dian)(dian)池。I CHG是(shi)(shi)可由(you)充(chong)(chong)電(dian)(dian)器(qi)控(kong)制的(de)電(dian)(dian)流，充(chong)(chong)電(dian)(dian)器(qi)根據(ju)此(ci)電(dian)(dian)流確(que)定是(shi)(shi)否充(chong)(chong)電(dian)(dian)。因此(ci)，充(chong)(chong)電(dian)(dian)器(qi)不(bu)能直接監視(shi)和控(kong)制有(you)效電(dian)(dian)池充(chong)(chong)電(dian)(dian)電(dian)(dian)流I BAT。

在(zai)預(yu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)階段，當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池單(dan)元電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓低于(yu)3.0V時(shi)(shi)(shi)，預(yu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流通常是(shi)快速充(chong)(chong)(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)10％。系(xi)(xi)統(tong)負載(zai)I SYS截取(qu)一些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，有(you)效充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流變小。這(zhe)不僅增(zeng)加(jia)(jia)了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間，而(er)且(qie)如果在(zai)預(yu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)定(ding)(ding)(ding)時(shi)(shi)(shi)器時(shi)(shi)(shi)段內電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓沒有(you)升至3V，則還可(ke)能(neng)導致(zhi)(zhi)預(yu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)定(ding)(ding)(ding)時(shi)(shi)(shi)器錯(cuo)誤結束。這(zhe)可(ke)能(neng)導致(zhi)(zhi)錯(cuo)誤預(yu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)安(an)全(quan)定(ding)(ding)(ding)時(shi)(shi)(shi)器警告，不是(shi)因(yin)(yin)為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池故障，而(er)是(shi)因(yin)(yin)為預(yu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流不足。系(xi)(xi)統(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流可(ke)能(neng)大于(yu)預(yu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，因(yin)(yin)此電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池不會充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)而(er)是(shi)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。為解決此問題，系(xi)(xi)統(tong)必須處于(yu)關(guan)斷模式或(huo)低靜態電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流待機模式，以(yi)便在(zai)預(yu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)安(an)全(quan)定(ding)(ding)(ding)時(shi)(shi)(shi)器周期(qi)內將(jiang)預(yu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)至3.0V以(yi)上。類似地，一旦電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池進(jin)入快速充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)階段，系(xi)(xi)統(tong)負載(zai)連續(xu)地中斷來自(zi)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)輸出的(de)(de)一些充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，增(zeng)加(jia)(jia)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間并終止高安(an)全(quan)時(shi)(shi)(shi)間誤差。
