如何(he)在(zai)满足(zu)空间和(he)成本要求的同(tong)时(shi)，在(zai)很(hen)短(duan)的时(shi)间内提供锂(li)离(li)子(zi)充电(dian)管理(li)解决方案。聚合(he)物锂(li)离(li)子(zi)电(dian)池广泛应用(yong)于便(bian)携式消(xiao)费电(dian)子(zi)产品中。

设计一个(ge)由(you)聚合(he)物锂(li)离子(zi)电(dian)(dian)(dian)(dian)(dian)池供电(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)系统(tong)的(de)(de)(de)传统(tong)方法是将(jiang)系统(tong)负载直接连(lian)接到电(dian)(dian)(dian)(dian)(dian)池上(shang)。系统(tong)负载会导致锂(li)离子(zi)电(dian)(dian)(dian)(dian)(dian)池持续放电(dian)(dian)(dian)(dian)(dian)，消耗电(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)寿命周期。为了(le)大限度地(di)延长锂(li)离子(zi)电(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)使(shi)用(yong)寿命，建(jian)议在有输(shu)入电(dian)(dian)(dian)(dian)(dian)源时(shi)(shi)适当终(zhong)(zhong)止(zhi)充电(dian)(dian)(dian)(dian)(dian)，并(bing)通过(guo)(guo)输(shu)入电(dian)(dian)(dian)(dian)(dian)源给系统(tong)供电(dian)(dian)(dian)(dian)(dian)。为了(le)防止(zhi)锂(li)离子(zi)电(dian)(dian)(dian)(dian)(dian)池过(guo)(guo)度充电(dian)(dian)(dian)(dian)(dian)，通常需(xu)要使(shi)用(yong)一个(ge)历时(shi)(shi)计时(shi)(shi)器作为辅助方法来(lai)关闭电(dian)(dian)(dian)(dian)(dian)池充电(dian)(dian)(dian)(dian)(dian)活(huo)动(dong)，直到满足适当的(de)(de)(de)终(zhong)(zhong)止(zhi)条件(jian)。

恒压级(ji)小(xiao)电(dian)(dian)流(liu)检测是锂(li)离(li)(li)子电(dian)(dian)池的(de)一种典型(xing)终(zhong)端(duan)方法。如(ru)果系统不(bu)断地(di)从锂(li)离(li)(li)子电(dian)(dian)池中吸取电(dian)(dian)流(liu)，小(xiao)电(dian)(dian)流(liu)不(bu)能被用(yong)来(lai)适当(dang)地(di)终(zhong)止充电(dian)(dian)管理(li)系统。它周期性地(di)打开和关闭，或由于定时器(qi)失败条件而(er)发(fa)生错误。聚合物锂(li)离(li)(li)子电(dian)(dian)池旨在克服锂(li)离(li)(li)子电(dian)(dian)池驱(qu)动应用(yong)中的(de)这些(xie)设(she)计挑(tiao)战。
